Posting from ASP.NET WebForms page to another URL

- by hajan

Few days ago I had a case when I needed to make FORM POST from my ASP.NET WebForms page to an external site URL. More specifically, I was working on implementing Simple Payment System (like Amazon, PayPal, MoneyBookers). The operator asks to make FORM POST request to a given URL in their website, sending parameters together with the post which are computed on my application level (access keys, secret keys, signature, return-URL… etc). So, since we are not allowed nesting another form inside the <form runat=”server”> … </form>, which is required because other controls in my ASPX code work on server-side, I thought to inject the HTML and create FORM with method=”POST”. After making some proof of concept and testing some scenarios, I’ve concluded that I can do this very fast in two ways: Using jQuery to create form on fly with the needed parameters and make submit() Using HttpContext.Current.Response.Write to write the form on server-side (code-behind) and embed JavaScript code that will do the post Both ways seemed fine. 1. Using jQuery to create FORM html code and Submit it. Let’s say we have ‘PAY NOW’ button in our ASPX code: <asp:Button ID="btnPayNow" runat="server" Text="Pay Now" /> Now, if we want to make this button submit a FORM using POST method to another website, the jQuery way should be as follows: <script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.5.1.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { $("#btnPayNow").click(function (event) { event.preventDefault(); //construct htmlForm string var htmlForm = "<form id='myform' method='POST' action='http://www.microsoft.com'>" + "<input type='hidden' id='name' value='hajan' />" + "</form>"; //Submit the form $(htmlForm).appendTo("body").submit(); }); }); </script> Yes, as you see, the code fires on btnPayNow click. It removes the default button behavior, then creates htmlForm string. After that using jQuery we append the form to the body and submit it. Inside the form, you can see I have set the htttp://www.microsoft.com URL, so after clicking the button you should be automatically redirected to the Microsoft website (just for test, of course for Payment I’m using Operator's URL). 2. Using HttpContext.Current.Response.Write to write the form on server-side (code-behind) and embed JavaScript code that will do the post The C# code behind should be something like this: public void btnPayNow_Click(object sender, EventArgs e) { string Url = "http://www.microsoft.com"; string formId = "myForm1"; StringBuilder htmlForm = new StringBuilder(); htmlForm.AppendLine("<html>"); htmlForm.AppendLine(String.Format("<body onload='document.forms[\"{0}\"].submit()'>",formId)); htmlForm.AppendLine(String.Format("<form id='{0}' method='POST' action='{1}'>", formId, Url)); htmlForm.AppendLine("<input type='hidden' id='name' value='hajan' />"); htmlForm.AppendLine("</form>"); htmlForm.AppendLine("</body>"); htmlForm.AppendLine("</html>"); HttpContext.Current.Response.Clear(); HttpContext.Current.Response.Write(htmlForm.ToString()); HttpContext.Current.Response.End(); } So, with this code we create htmlForm string using StringBuilder class and then just write the html to the page using HttpContext.Current.Response.Write. The interesting part here is that we submit the form using JavaScript code: document.forms["myForm1"].submit() This code runs on body load event, which means once the body is loaded the form is automatically submitted. Note: In order to test both solutions, create two applications on your web server and post the form from first to the second website, then get the values in the second website using Request.Form[“input-field-id”] I hope this was useful post for you.

Extracting the Date from a DateTime in Entity Framework 4 and LINQ

- by Ken Cox [MVP]

In my current ASP.NET 4 project, I’m displaying dates in a GridDateTimeColumn of Telerik’s ASP.NET Radgrid control. I don’t care about the time stuff, so my DataFormatString shows only the date bits: <telerik:GridDateTimeColumn FilterControlWidth="100px" DataField="DateCreated" HeaderText="Created" SortExpression="DateCreated" ReadOnly="True" UniqueName="DateCreated" PickerType="DatePicker" DataFormatString="{0:dd MMM yy}"> My problem was that I couldn’t get the built-in column filtering (it uses Telerik’s DatePicker control) to behave. The DatePicker assumes that the time is 00:00:00 but the data would have times like 09:22:21. So, when you select a date and apply the EqualTo filter, you get no results. You would get results if all the time portions were 00:00:00. In essence, I wanted my Entity Framework query to give the DatePicker what it wanted… a Date without the Time portion. Fortunately, EF4 provides the TruncateTime function. After you include Imports System.Data.Objects.EntityFunctions You’ll find that your EF queries will accept the TruncateTime function. Here’s my routine: Protected Sub RadGrid1_NeedDataSource _ (ByVal source As Object, _ ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) _ Handles RadGrid1.NeedDataSource Dim ent As New OfficeBookDBEntities1 Dim TopBOMs = From t In ent.TopBom, i In ent.Items _ Where t.BusActivityID = busActivityID _ And i.BusActivityID And t.ItemID = i.RecordID _ Order By t.DateUpdated Descending _ Select New With {.TopBomID = t.TopBomID, .ItemID = t.ItemID, _ .PartNumber = i.PartNumber, _ .Description = i.Description, .Notes = t.Notes, _ .DateCreated = TruncateTime(t.DateCreated), _ .DateUpdated = TruncateTime(t.DateUpdated)} RadGrid1.DataSource = TopBOMs End Sub Now when I select March 14, 2011 on the DatePicker, the filter doesn’t stumble on time values that don’t make sense. Full Disclosure: Telerik gives me (and other developer MVPs) free copies of their suite.

WLS MBeans

- by Jani Rautiainen

WLS provides a set of Managed Beans (MBeans) to configure, monitor and manage WLS resources. We can use the WLS MBeans to automate some of the tasks related to the configuration and maintenance of the WLS instance. The MBeans can be accessed a number of ways; using various UIs and programmatically using Java or WLST Python scripts.For customization development we can use the features to e.g. manage the deployed customization in MDS, control logging levels, automate deployment of dependent libraries etc. This article is an introduction on how to access and use the WLS MBeans. The goal is to illustrate the various access methods in a single article; the details of the features are left to the linked documentation.This article covers Windows based environment, steps for Linux would be similar however there would be some differences e.g. on how the file paths are defined. MBeansThe WLS MBeans can be categorized to runtime and configuration MBeans.The Runtime MBeans can be used to access the runtime information about the server and its resources. The data from runtime beans is only available while the server is running. The runtime beans can be used to e.g. check the state of the server or deployment.The Configuration MBeans contain information about the configuration of servers and resources. The configuration of the domain is stored in the config.xml file and the configuration MBeans can be used to access and modify the configuration data. For more information on the WLS MBeans refer to: Understanding WebLogic Server MBeans WLS MBean reference Java Management Extensions (JMX)We can use JMX APIs to access the WLS MBeans. This allows us to create Java programs to configure, monitor, and manage WLS resources. In order to use the WLS MBeans we need to add the following library into the class-path: WL_HOME\lib\wljmxclient.jar Connecting to a WLS MBean server The WLS MBeans are contained in a Mbean server, depending on the requirement we can connect to (MBean Server / JNDI Name): Domain Runtime MBean Server weblogic.management.mbeanservers.domainruntime Runtime MBean Server weblogic.management.mbeanservers.runtime Edit MBean Server weblogic.management.mbeanservers.edit To connect to the WLS MBean server first we need to create a map containing the credentials; Hashtable<String, String> param = new Hashtable<String, String>(); param.put(Context.SECURITY_PRINCIPAL, "weblogic"); param.put(Context.SECURITY_CREDENTIALS, "weblogic1"); param.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES, "weblogic.management.remote"); These define the user, password and package containing the protocol. Next we create the connection: JMXServiceURL serviceURL = new JMXServiceURL("t3","127.0.0.1",7101, "/jndi/weblogic.management.mbeanservers.domainruntime"); JMXConnector connector = JMXConnectorFactory.connect(serviceURL, param); MBeanServerConnection connection = connector.getMBeanServerConnection(); With the connection we can now access the MBeans for the WLS instance. For a complete example see Appendix A of this post. For more details refer to Accessing WebLogic Server MBeans with JMX Accessing WLS MBeans The WLS MBeans are structured hierarchically; in order to access content we need to know the path to the MBean we are interested in. The MBean is accessed using “MBeanServerConnection. getAttribute” API. WLS provides entry points to the hierarchy allowing us to navigate all the WLS MBeans in the hierarchy (MBean Server / JMX object name): Domain Runtime MBean Server com.bea:Name=DomainRuntimeService,Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean Runtime MBean Servers com.bea:Name=RuntimeService,Type=weblogic.management.mbeanservers.runtime.RuntimeServiceMBean Edit MBean Server com.bea:Name=EditService,Type=weblogic.management.mbeanservers.edit.EditServiceMBean For example we can access the Domain Runtime MBean using: ObjectName service = new ObjectName( "com.bea:Name=DomainRuntimeService," + "Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean"); Same syntax works for any “child” WLS MBeans e.g. to find out all application deployments we can: ObjectName domainConfig = (ObjectName)connection.getAttribute(service,"DomainConfiguration"); ObjectName[] appDeployments = (ObjectName[])connection.getAttribute(domainConfig,"AppDeployments"); Alternatively we could access the same MBean using the full syntax: ObjectName domainConfig = new ObjectName("com.bea:Location=DefaultDomain,Name=DefaultDomain,Type=Domain"); ObjectName[] appDeployments = (ObjectName[])connection.getAttribute(domainConfig,"AppDeployments"); For more details refer to Accessing WebLogic Server MBeans with JMX Invoking operations on WLS MBeans The WLS MBean operations can be invoked with MBeanServerConnection. invoke API; in the following example we query the state of “AppsLoggerService” application: ObjectName appRuntimeStateRuntime = new ObjectName("com.bea:Name=AppRuntimeStateRuntime,Type=AppRuntimeStateRuntime"); Object[] parameters = { "AppsLoggerService", "DefaultServer" }; String[] signature = { "java.lang.String", "java.lang.String" }; String result = (String)connection.invoke(appRuntimeStateRuntime,"getCurrentState",parameters, signature); The result returned should be "STATE_ACTIVE" assuming the "AppsLoggerService" application is up and running. WebLogic Scripting Tool (WLST) The WebLogic Scripting Tool (WLST) is a command-line scripting environment that we can access the same WLS MBeans. The tool is located under: $MW_HOME\oracle_common\common\bin\wlst.bat Do note that there are several instances of the wlst script under the $MW_HOME, each of them works, however the commands available vary, so we want to use the one under “oracle_common”. The tool is started in offline mode. In offline mode we can access and manipulate the domain configuration. In online mode we can access the runtime information. We connect to the Administration Server : connect("weblogic","weblogic1", "t3://127.0.0.1:7101") In both online and offline modes we can navigate the WLS MBean using commands like "ls" to print content and "cd" to navigate between objects, for example: All the commands available can be obtained with: help('all') For details of the tool refer to WebLogic Scripting Tool and for the commands available WLST Command and Variable Reference. Also do note that the WLST tool can be invoked from Java code in Embedded Mode. Running Scripts The WLST tool allows us to automate tasks using Python scripts in Script Mode. The script can be manually created or recorded by the WLST tool. Example commands of recording a script: startRecording("c:/temp/recording.py") <commands that we want to record> stopRecording() We can run the script from WLST: execfile("c:/temp/recording.py") We can also run the script from the command line: C:\apps\Oracle\Middleware\oracle_common\common\bin\wlst.cmd c:/temp/recording.py There are various sample scripts are provided with the WLS instance. UI to Access the WLS MBeans There are various UIs through which we can access the WLS MBeans. Oracle Enterprise Manager Fusion Middleware Control Oracle WebLogic Server Administration Console Fusion Middleware Control MBean Browser In the integrated JDeveloper environment only the Oracle WebLogic Server Administration Console is available to us. For more information refer to the documentation, one noteworthy feature in the console is the ability to record WLST scripts based on the navigation. In addition to the UIs above the JConsole included in the JDK can be used to access the WLS MBeans. The JConsole needs to be started with specific parameter to force WLS objects to be used and jar files in the classpath: "C:\apps\Oracle\Middleware\jdk160_24\bin\jconsole" -J-Djava.class.path=C:\apps\Oracle\Middleware\jdk160_24\lib\jconsole.jar;C:\apps\Oracle\Middleware\jdk160_24\lib\tools.jar;C:\apps\Oracle\Middleware\wlserver_10.3\server\lib\wljmxclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote For more details refer to the Accessing Custom MBeans from JConsole. Summary In this article we have covered various ways we can access and use the WLS MBeans in context of integrated WLS in JDeveloper to be used for Fusion Application customization development.

Dynamic XAP loading in Task-It - Part 1

Download Source Code NOTE 1: The source code provided is running against the RC versions of Silverlight 4 and VisualStudio 2010, so you will need to update to those bits to run it. NOTE 2: After downloading the source, be sure to set the .Web project as the StartUp Project, and Default.aspx as the Start Page In my MEF into post, MEF to the rescue in Task-It, I outlined a couple of issues I was facing and explained why I chose MEF (the Managed Extensibility Framework) to solve these issues. Other posts to check out There are a few other resources out there around dynamic XAP loading that you may want to review (by the way, Glenn Block is the main dude when it comes to MEF): Glenn Blocks 3-part series on a dynamically loaded dashboard Glenn and John Papas Silverlight TV video on dynamic xap loading These provide some great info, but didnt exactly cover the scenario I wanted to achieve in Task-Itand that is dynamically loading each of the apps pages the first time the user enters a page. The code In the code I provided for download above, I created a simple solution that shows the technique I used for dynamic XAP loading in Task-It, but without all of the other code that surrounds it. Taking all that other stuff away should make it easier to grasp. Having said that, there is still a fair amount of code involved. I am always looking for ways to make things simpler, and to achieve the desired result with as little code as possible, so if I find a better/simpler way I will blog about it, but for now this technique works for me. When I created this solution I started by creating a new Silverlight Navigation Application called DynamicXAP Loading. I then added the following line to my UriMappings in MainPage.xaml: <uriMapper:UriMapping Uri="/{assemblyName};component/{path}" MappedUri="/{assemblyName};component/{path}"/> In the section of MainPage.xaml that produces the page links in the upper right, I kept the Home link, but added a couple of new ones (page1 and page 2). These are the pages that will be dynamically (lazy) loaded: <StackPanel x:Name="LinksStackPanel" Style="{StaticResource LinksStackPanelStyle}"> <HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/Home" TargetName="ContentFrame" Content="home"/> <Rectangle Style="{StaticResource DividerStyle}"/> <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 1" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage1}"/> <Rectangle Style="{StaticResource DividerStyle}"/> <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 2" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage2}"/> </StackPanel> In App.xaml.cs I added a bit of MEF code. In Application_Startup I call a method called InitializeContainer, which creates a PackageCatalog (a MEF thing), then I create a CompositionContainer and pass it to the CompositionHost.Initialize method. This is boiler-plate MEF stuff that allows you to do 'composition' and import 'packages'. You're welcome to do a bit more MEF research on what is happening here if you'd like, but for the purpose of this example you can just trust that it works. :-) private void Application_Startup(object sender, StartupEventArgs e) { InitializeContainer(); this.RootVisual = new MainPage(); } private static void InitializeContainer() { var catalog = new PackageCatalog(); catalog.AddPackage(Package.Current); var container = new CompositionContainer(catalog); container.ComposeExportedValue(catalog); CompositionHost.Initialize(container); } Infrastructure In the sample code you'll notice that there is a project in the solution called DynamicXAPLoading.Infrastructure. This is simply a Silverlight Class Library project that I created just to move stuff I considered application 'infrastructure' code into a separate place, rather than cluttering the main Silverlight project (DynamicXapLoading). I did this same thing in Task-It, as the amount of this type of code was starting to clutter up the Silverlight project, and it just seemed to make sense to move things like Enums, Constants and the like off to a separate place. In the DynamicXapLoading.Infrastructure project you'll see 3 classes: Enums - There is only one enum in here called ModuleEnum. We'll use these later. PageMetadata - We will use this class later to add metadata to a new dynamically loaded project. ViewModelBase - This is simply a base class for view models that we will use in this, as well as future samples. As mentioned in my MVVM post, I will be using the MVVM pattern throughout my code for reasons detailed in the post. By the way, the ViewModelExtension class in there allows me to do strongly-typed property changed notification, so rather than OnPropertyChanged("MyProperty"), I can do this.OnPropertyChanged(p => p.MyProperty). It's just a less error-prown approach, because if you don't spell "MyProperty" correctly using the first method, nothing will break, it just won't work. Adding a new page We currently have a couple of pages that are being dynamically (lazy) loaded, but now let's add a third page. 1. First, create a new Silverlight Application project: In this example I call it Page3. In the future you may prefer to use a different name, like DynamicXAPLoading.Page3, or even DynamicXAPLoading.Modules.Page3. It can be whatever you want. In my Task-It application I used the latter approach (with 'Modules' in the name). I do think of these application as 'modules', but Prism uses the same term, so some folks may not like that. Use whichever naming convention you feel is appropriate, but for now Page3 will do. When you change the name to Page3 and click OK, you will be presented with the Add New Project dialog: It is important that you leave the 'Host the Silverlight application in a new or existing Web site in the solution' checked, and the .Web project will be selected in the dropdown below. This will create the .xap file for this project under ClientBin in the .Web project, which is where we want it. 2. Uncheck the 'Add a test page that references the application' checkbox, and leave everything else as is. 3. Once the project is created, you can delete App.xaml and MainPage.xaml. 4. You will need to add references your new project to the following: DynamicXAPLoading.Infrastructure.dll (this is a Project reference) DynamicNavigation.dll (this is in the Libs directory under the DynamicXAPLoading project) System.ComponentModel.Composition.dll System.ComponentModel.Composition.Initialization.dll System.Windows.Controls.Navigation.dll If you have installed the latest RC bits you will find the last 3 dll's under the .NET tab in the Add Referenced dialog. They live in the following location, or if you are on a 64-bit machine like me, it will be Program Files (x86). C:\Program Files\Microsoft SDKs\Silverlight\v4.0\Libraries\Client Now let's create some UI for our new project. 5. First, create a new Silverlight User Control called Page3.dyn.xaml 6. Paste the following code into the xaml: <dyn:DynamicPageShim xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation" xmlns:my="clr-namespace:Page3;assembly=Page3"> <my:Page3Host /> </dyn:DynamicPageShim> This is just a 'shim', part of David Poll's technique for dynamic loading. 7. Expand the icon next to Page3.dyn.xaml and delete the code-behind file (Page3.dyn.xaml.cs). 8. Next we will create a control that will 'host' our page. Create another Silverlight User Control called Page3Host.xaml and paste in the following XAML: <dyn:DynamicPage x:Class="Page3.Page3Host" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation" xmlns:Views="clr-namespace:Page3.Views" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400" Title="Page 3"> <Views:Page3/> </dyn:DynamicPage> 9. Now paste the following code into the code-behind for this control: using DynamicXAPLoading.Infrastructure; namespace Page3 { [PageMetadata(NavigateUri = "/Page3;component/Page3.dyn.xaml", Module = Enums.Page3)] public partial class Page3Host { public Page3Host() { InitializeComponent(); } } } Notice that we are now using that PageMetadata custom attribute class that we created in the Infrastructure project, and setting its two properties. NavigateUri - This tells it that the assembly is called Page3 (with a slash beforehand), and the page we want to load is Page3.dyn.xaml...our 'shim'. That line we added to the UriMapper in MainPage.xaml will use this information to load the page. Module - This goes back to that ModuleEnum class in our Infrastructure project. However, setting the Module to ModuleEnum.Page3 will cause a compilation error, so... 10. Go back to that Enums.cs under the Infrastructure project and add a 3rd entry for Page3: public enum ModuleEnum { Page1, Page2, Page3 } 11. Now right-click on the Page3 project and add a folder called Views. 12. Right-click on the Views folder and create a new Silverlight User Control called Page3.xaml. We won't bother creating a view model for this User Control as I did in the Page 1 and Page 2 projects, just for the sake of simplicity. Feel free to add one if you'd like though, and copy the code from one of those other projects. Right now those view models aren't really doing anything anyway...though they will in my next post. :-) 13. Now let's replace the xaml for Page3.xaml with the following: <dyn:DynamicPage x:Class="Page3.Views.Page3" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400" Style="{StaticResource PageStyle}"> <Grid x:Name="LayoutRoot"> <ScrollViewer x:Name="PageScrollViewer" Style="{StaticResource PageScrollViewerStyle}"> <StackPanel x:Name="ContentStackPanel"> <TextBlock x:Name="HeaderText" Style="{StaticResource HeaderTextStyle}" Text="Page 3"/> <TextBlock x:Name="ContentText" Style="{StaticResource ContentTextStyle}" Text="Page 3 content"/> </StackPanel> </ScrollViewer> </Grid> </dyn:DynamicPage> 14. And in the code-behind remove the inheritance from UserControl, so it should look like this: namespace Page3.Views { public partial class Page3 { public Page3() { InitializeComponent(); } } } One thing you may have noticed is that the base class for the last two User Controls we created is DynamicPage. Once again, we are using the infrastructure that David Poll created. 15. OK, a few last things. We need a link on our main page so that we can access our new page. In MainPage.xaml let's update our links to look like this: <StackPanel x:Name="LinksStackPanel" Style="{StaticResource LinksStackPanelStyle}"> <HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/Home" TargetName="ContentFrame" Content="home"/> <Rectangle Style="{StaticResource DividerStyle}"/> <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 1" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage1}"/> <Rectangle Style="{StaticResource DividerStyle}"/> <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 2" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage2}"/> <Rectangle Style="{StaticResource DividerStyle}"/> <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 3" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage3}"/> </StackPanel> 16. Next, we need to add the following at the bottom of MainPageViewModel in the ViewModels directory of our DynamicXAPLoading project: public ModuleEnum ModulePage3 { get { return ModuleEnum.Page3; } } 17. And at last, we need to add a case for our new page to the switch statement in MainPageViewModel: switch (module) { case ModuleEnum.Page1: DownloadPackage("Page1.xap"); break; case ModuleEnum.Page2: DownloadPackage("Page2.xap"); break; case ModuleEnum.Page3: DownloadPackage("Page3.xap"); break; default: break; } Now fire up the application and click the page 1, page 2 and page 3 links. What you'll notice is that there is a 2-second delay the first time you hit each page. That is because I added the following line to the Navigate method in MainPageViewModel: Thread.Sleep(2000); // Simulate a 2 second initial loading delay The reason I put this in there is that I wanted to simulate a delay the first time the page loads (as the .xap is being downloaded from the server). You'll notice that after the first hit to the page though that there is no delay...that's because the .xap has already been downloaded. Feel free to comment out this 2-second delay, or remove it if you'd like. I just wanted to show how subsequent hits to the page would be quicker than the initial one. By the way, you may want to display some sort of BusyIndicator while the .xap is loading. I have that in my Task-It appplication, but for the sake of simplicity I did not include it here. In the future I'll blog about how I show and hide the BusyIndicator using events (I'm currently using the eventing framework in Prism for that, but may move to the one in the MVVM Light Toolkit some time soon). Whew, that felt like a lot of steps, but it does work quite nicely. As I mentioned earlier, I'll try to find ways to simplify the code (I'd like to get away from having things like hard-coded .xap file names) and will blog about it in the future if I find a better way. In my next post, I'll talk more about what is actually happening with the code that makes this all work.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

How to install Oracle Weblogic Server using OS-specific Package installer?(Linux/Solaris)

- by PratikS -- Oracle

Note: OS-specific Package installer As the name suggests the installer is platform specific. It is meant for installation with a 32bit JVM only. Both SUN and JROCKIT 32 bit JDKs come bundled with "OS-specific Package installer", so no need to install the JDK in advance. There are three different ways of installing Oracle Weblogic Server: Graphical mode Console mode Silent mode For Linux/Solaris: Steps to install OS-specific Package .bin installer(for Linux/Solaris) are almost same as windows except for the way we launch the installation.Installer: wls_<version>_<linux/solaris>32.bin (E.g. wls1036_linux32.bin/wls1036_solaris32.bin) 1) Graphical mode: Log in to the target UNIX system. Go to the directory that contains the installation program.(Make sure GUI is enabled or else it will default to console mode) Launch the installation by entering the following commands: [weblogic@pratik ~]$ pwd/home/oracle[weblogic@pratik ~]$ cd WLSInstallers/[weblogic@pratik WLSInstallers]$ ls -ltrtotal 851512-rw-rw-r-- 1 oracle oracle 871091023 Dec 22 2011 wls1036_linux32.bin[weblogic@pratik WLSInstallers]$ chmod a+x wls1036_linux32.bin[weblogic@pratik WLSInstallers]$ ls -ltrtotal 851512-rwxrwxr-x 1 oracle oracle 871091023 Dec 22 2011 wls1036_linux32.bin[weblogic@pratik WLSInstallers]$ ./wls1036_linux32.bin As soon as you run ./wls1036_linux32.bin with GUI enabled you would see the following screen: Rest of the screens and steps are similar to that of Graphical mode installation on windows, refer: How to install Oracle Weblogic Server using OS-specific Package installer?(Windows) 2) Console mode: Log in to the target UNIX system.

Synchronize Data between a Silverlight ListBox and a User Control

- by psheriff

One of the great things about XAML is the powerful data-binding capabilities. If you load up a list box with a collection of objects, you can display detail data about each object without writing any C# or VB.NET code. Take a look at Figure 1 that shows a collection of Product objects in a list box. When you click on a list box you bind the current Product object selected in the list box to a set of controls in a user control with just a very simple Binding statement in XAML. Figure 1: Synchronizing a ListBox to a User Control is easy with Data Binding Product and Products Classes To illustrate this data binding feature I am going to just create some local data instead of using a WCF service. The code below shows a Product class that has three properties, namely, ProductId, ProductName and Price. This class also has a constructor that takes 3 parameters and allows us to set the 3 properties in an instance of our Product class. C#public class Product{ public Product(int productId, string productName, decimal price) { ProductId = productId; ProductName = productName; Price = price; } public int ProductId { get; set; } public string ProductName { get; set; } public decimal Price { get; set; }} VBPublic Class Product Public Sub New(ByVal _productId As Integer, _ ByVal _productName As String, _ ByVal _price As Decimal) ProductId = _productId ProductName = _productName Price = _price End Sub Private mProductId As Integer Private mProductName As String Private mPrice As Decimal Public Property ProductId() As Integer Get Return mProductId End Get Set(ByVal value As Integer) mProductId = value End Set End Property Public Property ProductName() As String Get Return mProductName End Get Set(ByVal value As String) mProductName = value End Set End Property Public Property Price() As Decimal Get Return mPrice End Get Set(ByVal value As Decimal) mPrice = value End Set End PropertyEnd Class To fill up a list box you need a collection class of Product objects. The code below creates a generic collection class of Product objects. In the constructor of the Products class I have hard-coded five product objects and added them to the collection. In a real-world application you would get your data through a call to service to fill the list box, but for simplicity and just to illustrate the data binding, I am going to just hard code the data. C#public class Products : List<Product>{ public Products() { this.Add(new Product(1, "Microsoft VS.NET 2008", 1000)); this.Add(new Product(2, "Microsoft VS.NET 2010", 1000)); this.Add(new Product(3, "Microsoft Silverlight 4", 1000)); this.Add(new Product(4, "Fundamentals of N-Tier eBook", 20)); this.Add(new Product(5, "ASP.NET Security eBook", 20)); }} VBPublic Class Products Inherits List(Of Product) Public Sub New() Me.Add(New Product(1, "Microsoft VS.NET 2008", 1000)) Me.Add(New Product(2, "Microsoft VS.NET 2010", 1000)) Me.Add(New Product(3, "Microsoft Silverlight 4", 1000)) Me.Add(New Product(4, "Fundamentals of N-Tier eBook", 20)) Me.Add(New Product(5, "ASP.NET Security eBook", 20)) End SubEnd Class The Product Detail User Control Below is a user control (named ucProduct) that is used to display the product detail information seen in the bottom portion of Figure 1. This is very basic XAML that just creates a text block and a text box control for each of the three properties in the Product class. Notice the {Binding Path=[PropertyName]} on each of the text box controls. This means that if the DataContext property of this user control is set to an instance of a Product class, then the data in the properties of that Product object will be displayed in each of the text boxes. <UserControl x:Class="SL_SyncListBoxAndUserControl_CS.ucProduct" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" HorizontalAlignment="Left" VerticalAlignment="Top"> <Grid Margin="4"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition MinWidth="120" /> <ColumnDefinition /> </Grid.ColumnDefinitions> <TextBlock Grid.Row="0" Grid.Column="0" Text="Product Id" /> <TextBox Grid.Row="0" Grid.Column="1" Text="{Binding Path=ProductId}" /> <TextBlock Grid.Row="1" Grid.Column="0" Text="Product Name" /> <TextBox Grid.Row="1" Grid.Column="1" Text="{Binding Path=ProductName}" /> <TextBlock Grid.Row="2" Grid.Column="0" Text="Price" /> <TextBox Grid.Row="2" Grid.Column="1" Text="{Binding Path=Price}" /> </Grid></UserControl> Synchronize ListBox with User Control You are now ready to fill the list box with the collection class of Product objects and then bind the SelectedItem of the list box to the Product detail user control. The XAML below is the complete code for Figure 1. <UserControl x:Class="SL_SyncListBoxAndUserControl_CS.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:src="clr-namespace:SL_SyncListBoxAndUserControl_CS" VerticalAlignment="Top" HorizontalAlignment="Left"> <UserControl.Resources> <src:Products x:Key="productCollection" /> </UserControl.Resources> <Grid x:Name="LayoutRoot" Margin="4" Background="White"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <ListBox x:Name="lstData" Grid.Row="0" BorderBrush="Black" BorderThickness="1" ItemsSource="{Binding Source={StaticResource productCollection}}" DisplayMemberPath="ProductName" /> <src:ucProduct x:Name="prodDetail" Grid.Row="1" DataContext="{Binding ElementName=lstData, Path=SelectedItem}" /> </Grid></UserControl> The first step to making this happen is to reference the Silverlight project (SL_SyncListBoxAndUserControl_CS) where the Product and Products classes are located. I added this namespace and assigned it a namespace prefix of “src” as shown in the line below: xmlns:src="clr-namespace:SL_SyncListBoxAndUserControl_CS" Next, to use the data from an instance of the Products collection, you create a UserControl.Resources section in the XAML and add a tag that creates an instance of the Products class and assigns it a key of “productCollection”. <UserControl.Resources> <src:Products x:Key="productCollection" /> </UserControl.Resources> Next, you bind the list box to this productCollection object using the ItemsSource property. You bind the ItemsSource of the list box to the static resource named productCollection. You can then set the DisplayMemberPath attribute of the list box to any property of the Product class that you want. In the XAML below I used the ProductName property. <ListBox x:Name="lstData" ItemsSource="{Binding Source={StaticResource productCollection}}" DisplayMemberPath="ProductName" /> You now need to create an instance of the ucProduct user contol below the list box. You do this by once again referencing the “src” namespace and typing in the name of the user control. You then set the DataContext property on this user control to a binding. The binding uses the ElementName attribute to bind to the list box name, in this case “lstData”. The Path of the data is SelectedItem. These two attributes together tell Silverlight to bind the DataContext to the selected item of the list box. That selected item is a Product object. So, once this is bound, the bindings on each text box in the user control are updated and display the current product information. <src:ucProduct x:Name="prodDetail" DataContext="{Binding ElementName=lstData, Path=SelectedItem}" /> Summary Once you understand the basics of data binding in XAML, you eliminate a lot code that is otherwise needed to move data into controls and out of controls back into an object. Connecting two controls together is easy by just binding using the ElementName and Path properties of the Binding markup extension. Another good tip out of this blog is use user controls and set the DataContext of the user control to have all of the data on the user control update through the bindings.

Improving WIF’s Claims-based Authorization - Part 3 (Usage)

- by Your DisplayName here!

In the previous posts I showed off some of the additions I made to WIF’s authorization infrastructure. I now want to show some samples how I actually use these extensions. The following code snippets are from Thinktecture.IdentityServer on Codeplex. The following shows the MVC attribute on the WS-Federation controller: [ClaimsAuthorize(Constants.Actions.Issue, Constants.Resources.WSFederation)] public class WSFederationController : Controller or… [ClaimsAuthorize(Constants.Actions.Administration, Constants.Resources.RelyingParty)] public class RelyingPartiesAdminController : Controller In other places I used the imperative approach (e.g. the WRAP endpoint): if (!ClaimsAuthorize.CheckAccess(principal, Constants.Actions.Issue, Constants.Resources.WRAP)) { Tracing.Error("User not authorized"); return new UnauthorizedResult("WRAP", true); } For the WCF WS-Trust endpoints I decided to use the per-request approach since the SOAP actions are well defined here. The corresponding authorization manager roughly looks like this: public class AuthorizationManager : ClaimsAuthorizationManager { public override bool CheckAccess(AuthorizationContext context) { var action = context.Action.First(); var id = context.Principal.Identities.First(); // if application authorization request if (action.ClaimType.Equals(ClaimsAuthorize.ActionType)) { return AuthorizeCore(action, context.Resource, context.Principal.Identity as IClaimsIdentity); } // if ws-trust issue request if (action.Value.Equals(WSTrust13Constants.Actions.Issue)) { return AuthorizeTokenIssuance(new Collection<Claim> { new Claim(ClaimsAuthorize.ResourceType, Constants.Resources.WSTrust) }, id); } return base.CheckAccess(context); } } You see that it is really easy now to distinguish between per-request and application authorization which makes the overall design much easier.

Create excel files with GemBox.Spreadsheet .NET component

- by hajan

Generating excel files from .NET code is not always a very easy task, especially if you need to make some formatting or you want to do something very specific that requires extra coding. I’ve recently tried the GemBox Spreadsheet and I would like to share my experience with you. First of all, you can install GemBox Spreadsheet library from VS.NET 2010 Extension manager by searching in the gallery: Go in the Online Gallery tab (as in the picture bellow) and write GemBox in the Search box on top-right of the Extension Manager, so you will get the following result: Click Download on GemBox.Spreadsheet and you will be directed to product website. Click on the marked link then you will get to the following page where you have the component download link Once you download it, install the MSI file. Open the installation folder and find the Bin folder. There you have GemBox.Spreadsheet.dll in three folders each for different .NET Framework version. Now, lets move to Visual Studio.NET. 1. Create sample ASP.NET Web Application and give it a name. 2. Reference The GemBox.Spreadsheet.dll file in your project So you don’t need to search for the dll file in your disk but you can simply find it in the .NET tab in ‘Add Reference’ window and you have all three versions. I chose the version for 4.0.30319 runtime. Next, I will retrieve data from my Pubs database. I’m using Entity Framework. Here is the code (read the comments in it): //get data from pubs database, tables: authors, titleauthor, titles pubsEntities context = new pubsEntities(); var authorTitles = (from a in context.authors join tl in context.titleauthor on a.au_id equals tl.au_id join t in context.titles on tl.title_id equals t.title_id select new AuthorTitles { Name = a.au_fname, Surname = a.au_lname, Title = t.title, Price = t.price, PubDate = t.pubdate }).ToList(); //using GemBox library now ExcelFile myExcelFile = new ExcelFile(); ExcelWorksheet excWsheet = myExcelFile.Worksheets.Add("Hajan's worksheet"); excWsheet.Cells[0, 0].Value = "Pubs database Authors and Titles"; excWsheet.Cells[0, 0].Style.Borders.SetBorders(MultipleBorders.Bottom,System.Drawing.Color.Red,LineStyle.Thin); excWsheet.Cells[0, 1].Style.Borders.SetBorders(MultipleBorders.Bottom, System.Drawing.Color.Red, LineStyle.Thin); int numberOfColumns = 5; //the number of properties in the authorTitles we have //for each column for (int c = 0; c < numberOfColumns; c++) { excWsheet.Columns[c].Width = 25 * 256; //set the width to each column } //header row cells excWsheet.Rows[2].Cells[0].Value = "Name"; excWsheet.Rows[2].Cells[1].Value = "Surname"; excWsheet.Rows[2].Cells[2].Value = "Title"; excWsheet.Rows[2].Cells[3].Value = "Price"; excWsheet.Rows[2].Cells[4].Value = "PubDate"; //bind authorTitles in the excel worksheet int currentRow = 3; foreach (AuthorTitles at in authorTitles) { excWsheet.Rows[currentRow].Cells[0].Value = at.Name; excWsheet.Rows[currentRow].Cells[1].Value = at.Surname; excWsheet.Rows[currentRow].Cells[2].Value = at.Title; excWsheet.Rows[currentRow].Cells[3].Value = at.Price; excWsheet.Rows[currentRow].Cells[4].Value = at.PubDate; currentRow++; } //stylizing my excel file look CellStyle style = new CellStyle(myExcelFile); style.HorizontalAlignment = HorizontalAlignmentStyle.Left; style.VerticalAlignment = VerticalAlignmentStyle.Center; style.Font.Color = System.Drawing.Color.DarkRed; style.WrapText = true; style.Borders.SetBorders(MultipleBorders.Top | MultipleBorders.Left | MultipleBorders.Right | MultipleBorders.Bottom, System.Drawing.Color.Black, LineStyle.Thin); //pay attention on this, we set created style on the given (firstRow, firstColumn, lastRow, lastColumn) //in my example: //firstRow = 2; firstColumn = 0; lastRow = authorTitles.Count+1; lastColumn = numberOfColumns-1; variable excWsheet.Cells.GetSubrangeAbsolute(3, 0, authorTitles.Count+2, numberOfColumns-1).Style = style; //save my excel file myExcelFile.SaveXls(Server.MapPath(".") + @"/myFile.xls"); The AuthorTitles class: public class AuthorTitles { public string Name { get; set; } public string Surname { get; set; } public string Title { get; set; } public decimal? Price { get; set; } public DateTime PubDate { get; set; } } The excel file will be generated in the root of your ASP.NET Web Application. The result is: There is a lot more you can do with this library. A set of good examples you have in the GemBox.Spreadsheet Samples Explorer application which comes together with the installation and you can find it by default in Start –> All Programs –> GemBox Software –> GemBox.Spreadsheet Samples Explorer. Hope this was useful for you. Best Regards, Hajan

Create nice animation on your ASP.NET Menu control using jQuery

- by hajan

In this blog post, I will show how you can apply some nice animation effects on your ASP.NET Menu control. ASP.NET Menu control offers many possibilities, but together with jQuery, you can make very rich, interactive menu accompanied with animations and effects. Lets start with an example: - Create new ASP.NET Web Application and give it a name - Open your Default.aspx page (or any other .aspx page where you will create the menu) - Our page ASPX code is: <form id="form1" runat="server"> <div id="menu"> <asp:Menu ID="Menu1" runat="server" Orientation="Horizontal" RenderingMode="List"> <Items> <asp:MenuItem NavigateUrl="~/Default.aspx" ImageUrl="~/Images/Home.png" Text="Home" Value="Home" /> <asp:MenuItem NavigateUrl="~/About.aspx" ImageUrl="~/Images/Friends.png" Text="About Us" Value="AboutUs" /> <asp:MenuItem NavigateUrl="~/Products.aspx" ImageUrl="~/Images/Box.png" Text="Products" Value="Products" /> <asp:MenuItem NavigateUrl="~/Contact.aspx" ImageUrl="~/Images/Chat.png" Text="Contact Us" Value="ContactUs" /> </Items> </asp:Menu> </div> </form> As you can see, we have ASP.NET Menu with Horizontal orientation and RenderMode=”List”. It has four Menu Items where for each I have specified NavigateUrl, ImageUrl, Text and Value properties. All images are in Images folder in the root directory of this web application. The images I’m using for this demo are from Free Web Icons. - Next, lets create CSS for the LI and A tags (place this code inside head tag) <style type="text/css"> li { border:1px solid black; padding:20px 20px 20px 20px; width:110px; background-color:Gray; color:White; cursor:pointer; } a { color:White; font-family:Tahoma; } </style> This is nothing very important and you can change the style as you want. - Now, lets reference the jQuery core library directly from Microsoft CDN. <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.min.js"></script> - And we get to the most interesting part, applying the animations with jQuery Before we move on writing jQuery code, lets see what is the HTML code that our ASP.NET Menu control generates in the client browser. <ul class="level1"> <li><a class="level1" href="Default.aspx"><img src="Images/Home.png" alt="" title="" class="icon" />Home</a></li> <li><a class="level1" href="About.aspx"><img src="Images/Friends.png" alt="" title="" class="icon" />About Us</a></li> <li><a class="level1" href="Products.aspx"><img src="Images/Box.png" alt="" title="" class="icon" />Products</a></li> <li><a class="level1" href="Contact.aspx"><img src="Images/Chat.png" alt="" title="" class="icon" />Contact Us</a></li> </ul> So, it generates unordered list which has class level1 and for each item creates li element with an anchor with image + menu text inside it. If we want to access the list element only from our menu (not other list element sin the page), we need to use the following jQuery selector: “ul.level1 li”, which will find all li elements which have parent element ul with class level1. Hence, the jQuery code is: <script type="text/javascript"> $(function () { $("ul.level1 li").hover(function () { $(this).stop().animate({ opacity: 0.7, width: "170px" }, "slow"); }, function () { $(this).stop().animate({ opacity: 1, width: "110px" }, "slow"); }); }); </script> I’m using hover, so that the animation will occur once we go over the menu item. The two different functions are one for the over, the other for the out effect. The following line $(this).stop().animate({ opacity: 0.7, width: "170px" }, "slow"); does the real job. So, this will first stop any previous animations (if any) that are in progress and will animate the menu item by giving to it opacity of 0.7 and changing the width to 170px (the default width is 110px as in the defined CSS style for li tag). This happens on mouse over. The second function on mouse out reverts the opacity and width properties to the default ones. The last parameter “slow” is the speed of the animation. The end result is: The complete ASPX code: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>ASP.NET Menu + jQuery</title> <style type="text/css"> li { border:1px solid black; padding:20px 20px 20px 20px; width:110px; background-color:Gray; color:White; cursor:pointer; } a { color:White; font-family:Tahoma; } </style> <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.min.js"></script> <script type="text/javascript"> $(function () { $("ul.level1 li").hover(function () { $(this).stop().animate({ opacity: 0.7, width: "170px" }, "slow"); }, function () { $(this).stop().animate({ opacity: 1, width: "110px" }, "slow"); }); }); </script> </head> <body> <form id="form1" runat="server"> <div id="menu"> <asp:Menu ID="Menu1" runat="server" Orientation="Horizontal" RenderingMode="List"> <Items> <asp:MenuItem NavigateUrl="~/Default.aspx" ImageUrl="~/Images/Home.png" Text="Home" Value="Home" /> <asp:MenuItem NavigateUrl="~/About.aspx" ImageUrl="~/Images/Friends.png" Text="About Us" Value="AboutUs" /> <asp:MenuItem NavigateUrl="~/Products.aspx" ImageUrl="~/Images/Box.png" Text="Products" Value="Products" /> <asp:MenuItem NavigateUrl="~/Contact.aspx" ImageUrl="~/Images/Chat.png" Text="Contact Us" Value="ContactUs" /> </Items> </asp:Menu> </div> </form> </body> </html> Hope this was useful.

UAT Testing for SOA 10G Clusters

- by [email protected]

A lot of customers ask how to verify their SOA clusters and make them production ready. Here is a list that I recommend using for 10G SOA Clusters. v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false EN-CA X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; mso-bidi-font-size:12.0pt; font-family:"Calibri","sans-serif"; mso-fareast-language:EN-US;} Test cases for each component - Oracle Application Server 10G General Application Server test cases This section is going to cover very General test cases to make sure that the Application Server cluster has been set up correctly and if you can start and stop all the components in the server via opmnct and AS Console. Test Case 1 Check if you can see AS instances in the console Implementation 1. Log on to the AS Console --> check to see if you can see all the nodes in your AS cluster. You should be able to see all the Oracle AS instances that are part of the cluster. This means that the OPMN clustering worked and the AS instances successfully joined the AS cluster. Result You should be able to see if all the instances in the AS cluster are listed in the EM console. If the instances are not listed here are the files to check to see if OPMN joined the cluster properly: $ORACLE_HOME\opmn\logs{*}opmn.log*$ORACLE_HOME\opmn\logs{*}opmn.dbg* If OPMN did not join the cluster properly, please check the opmn.xml file to make sure the discovery multicast address and port are correct (see this link for opmn documentation). Restart the whole instance using opmnctl stopall followed by opmnctl startall. Log on to AS console to see if instance is listed as part of the cluster. Test Case 2 Check to see if you can start/stop each component Implementation Check each OC4J component on each AS instanceStart each and every component through the AS console to see if they will start and stop.Do that for each and every instance. Result Each component should start and stop through the AS console. You can also verify if the component started by checking opmnctl status by logging onto each box associated with the cluster Test Case 3 Add/modify a datasource entry through AS console on a remote AS instance (not on the instance where EM is physically running) Implementation Pick an OC4J instanceCreate a new data-source through the AS consoleModify an existing data-source or connection pool (optional) Result Open $ORACLE_HOME\j2ee\<oc4j_name>\config\data-sources.xml to see if the new (and or the modified) connection details and data-source exist. If they do then the AS console has successfully updated a remote file and MBeans are communicating correctly. Test Case 4 Start and stop AS instances using opmnctl @cluster command Implementation 1. Go to $ORACLE_HOME\opmn\bin and use the opmnctl @cluster to start and stop the AS instances Result Use opmnctl @cluster status to check for start and stop statuses. HTTP server test cases This section will deal with use cases to test HTTP server failover scenarios. In these examples the HTTP server will be talking to the BPEL console (or any other web application that the client wants), so the URL will be _http://hostname:port\BPELConsole Test Case 1 Shut down one of the HTTP servers while accessing the BPEL console and see the requested routed to the second HTTP server in the cluster Implementation Access the BPELConsoleCheck $ORACLE_HOME\Apache\Apache\logs\access_log --> check for the timestamp and the URL that was accessed by the user. Timestamp and URL would look like this 1xx.2x.2xx.xxx [24/Mar/2009:16:04:38 -0500] "GET /BPELConsole=System HTTP/1.1" 200 15 After you have figured out which HTTP server this is running on, shut down this HTTP server by using opmnctl stopproc --> this is a graceful shutdown.Access the BPELConsole again (please note that you should have a LoadBalancer in front of the HTTP server and configured the Apache Virtual Host, see EDG for steps)Check $ORACLE_HOME\Apache\Apache\logs\access_log --> check for the timestamp and the URL that was accessed by the user. Timestamp and URL would look like above Result Even though you are shutting down the HTTP server the request is routed to the surviving HTTP server, which is then able to route the request to the BPEL Console and you are able to access the console. By checking the access log file you can confirm that the request is being picked up by the surviving node. Test Case 2 Repeat the same test as above but instead of calling opmnctl stopproc, pull the network cord of one of the HTTP servers, so that the LBR routes the request to the surviving HTTP node --> this is simulating a network failure. Test Case 3 In test case 1 we have simulated a graceful shutdown, in this case we will simulate an Apache crash Implementation Use opmnctl status -l to get the PID of the HTTP server that you would like forcefully bring downOn Linux use kill -9 <PID> to kill the HTTP serverAccess the BPEL console Result As you shut down the HTTP server, OPMN will restart the HTTP server. The restart may be so quick that the LBR may still route the request to the same server. One way to check if the HTTP server restared is to check the new PID and the timestamp in the access log for the BPEL console. BPEL test cases This section is going to cover scenarios dealing with BPEL clustering using jGroups, BPEL deployment and testing related to BPEL failover. Test Case 1 Verify that jGroups has initialized correctly. There is no real testing in this use case just a visual verification by looking at log files that jGroups has initialized correctly. Check the opmn log for the BPEL container for all nodes at $ORACLE_HOME/opmn/logs/<group name><container name><group name>~1.log. This logfile will contain jGroups related information during startup and steady-state operation. Soon after startup you should find log entries for UDP or TCP.Example jGroups Log Entries for UDPApr 3, 2008 6:30:37 PM org.collaxa.thirdparty.jgroups.protocols.UDP createSockets · INFO: sockets will use interface 144.25.142.172· · Apr 3, 2008 6:30:37 PM org.collaxa.thirdparty.jgroups.protocols.UDP createSockets· · INFO: socket information:· · local_addr=144.25.142.172:1127, mcast_addr=228.8.15.75:45788, bind_addr=/144.25.142.172, ttl=32· sock: bound to 144.25.142.172:1127, receive buffer size=64000, send buffer size=32000· mcast_recv_sock: bound to 144.25.142.172:45788, send buffer size=32000, receive buffer size=64000· mcast_send_sock: bound to 144.25.142.172:1128, send buffer size=32000, receive buffer size=64000· Apr 3, 2008 6:30:37 PM org.collaxa.thirdparty.jgroups.protocols.TP$DiagnosticsHandler bindToInterfaces· · -------------------------------------------------------· · GMS: address is 144.25.142.172:1127· ------------------------------------------------------- Example jGroups Log Entries for TCPApr 3, 2008 6:23:39 PM org.collaxa.thirdparty.jgroups.blocks.ConnectionTable start · INFO: server socket created on 144.25.142.172:7900· · Apr 3, 2008 6:23:39 PM org.collaxa.thirdparty.jgroups.protocols.TP$DiagnosticsHandler bindToInterfaces· · -------------------------------------------------------· GMS: address is 144.25.142.172:7900------------------------------------------------------- In the log below the "socket created on" indicates that the TCP socket is established on the own node at that IP address and port the "created socket to" shows that the second node has connected to the first node, matching the logfile above with the IP address and port.Apr 3, 2008 6:25:40 PM org.collaxa.thirdparty.jgroups.blocks.ConnectionTable start · INFO: server socket created on 144.25.142.173:7901· · Apr 3, 2008 6:25:40 PM org.collaxa.thirdparty.jgroups.protocols.TP$DiagnosticsHandler bindToInterfaces· · ------------------------------------------------------· GMS: address is 144.25.142.173:7901· -------------------------------------------------------· Apr 3, 2008 6:25:41 PM org.collaxa.thirdparty.jgroups.blocks.ConnectionTable getConnectionINFO: created socket to 144.25.142.172:7900 Result By reviewing the log files, you can confirm if BPEL clustering at the jGroups level is working and that the jGroup channel is communicating. Test Case 2 Test connectivity between BPEL Nodes Implementation Test connections between different cluster nodes using ping, telnet, and traceroute. The presence of firewalls and number of hops between cluster nodes can affect performance as they have a tendency to take down connections after some time or simply block them.Also reference Metalink Note 413783.1: "How to Test Whether Multicast is Enabled on the Network." Result Using the above tools you can confirm if Multicast is working and whether BPEL nodes are commnunicating. Test Case3 Test deployment of BPEL suitcase to one BPEL node. Implementation Deploy a HelloWorrld BPEL suitcase (or any other client specific BPEL suitcase) to only one BPEL instance using ant, or JDeveloper or via the BPEL consoleLog on to the second BPEL console to check if the BPEL suitcase has been deployed Result If jGroups has been configured and communicating correctly, BPEL clustering will allow you to deploy a suitcase to a single node, and jGroups will notify the second instance of the deployment. The second BPEL instance will go to the DB and pick up the new deployment after receiving notification. The result is that the new deployment will be "deployed" to each node, by only deploying to a single BPEL instance in the BPEL cluster. Test Case 4 Test to see if the BPEL server failsover and if all asynch processes are picked up by the secondary BPEL instance Implementation Deploy a 2 Asynch process: A ParentAsynch Process which calls a ChildAsynchProcess with a variable telling it how many times to loop or how many seconds to sleepA ChildAsynchProcess that loops or sleeps or has an onAlarmMake sure that the processes are deployed to both serversShut down one BPEL serverOn the active BPEL server call ParentAsynch a few times (use the load generation page)When you have enough ParentAsynch instances shut down this BPEL instance and start the other one. Please wait till this BPEL instance shuts down fully before starting up the second one.Log on to the BPEL console and see that the instance were picked up by the second BPEL node and completed Result The BPEL instance will failover to the secondary node and complete the flow ESB test cases This section covers the use cases involved with testing an ESB cluster.

Connect ViewModel and View using Unity

- by brainbox

In this post i want to describe the approach of connecting View and ViewModel which I'm using in my last project.The main idea is to do it during resolve inside of unity container. It can be achived using InjectionFactory introduced in Unity 2.0 public static class MVVMUnityExtensions{ public static void RegisterView<TView, TViewModel>(this IUnityContainer container) where TView : FrameworkElement { container.RegisterView<TView, TView, TViewModel>(); } public static void RegisterView<TViewFrom, TViewTo, TViewModel>(this IUnityContainer container) where TViewTo : FrameworkElement, TViewFrom { container.RegisterType<TViewFrom>(new InjectionFactory( c => { var model = c.Resolve<TViewModel>(); var view = Activator.CreateInstance<TViewTo>(); view.DataContext = model; return view; } )); }}}And here is the sample how it could be used:var unityContainer = new UnityContainer();unityContainer.RegisterView<IFooView, FooView, FooViewModel>();IFooView view = unityContainer.Resolve<IFooView>(); // view with injected viewmodel in its datacontextPlease tell me your prefered way to connect viewmodel and view.

New Validation Attributes in ASP.NET MVC 3 Future

- by imran_ku07

Introduction: Validating user inputs is an very important step in collecting information from users because it helps you to prevent errors during processing data. Incomplete or improperly formatted user inputs will create lot of problems for your application. Fortunately, ASP.NET MVC 3 makes it very easy to validate most common input validations. ASP.NET MVC 3 includes Required, StringLength, Range, RegularExpression, Compare and Remote validation attributes for common input validation scenarios. These validation attributes validates most of your user inputs but still validation for Email, File Extension, Credit Card, URL, etc are missing. Fortunately, some of these validation attributes are available in ASP.NET MVC 3 Future. In this article, I will show you how to leverage Email, Url, CreditCard and FileExtensions validation attributes(which are available in ASP.NET MVC 3 Future) in ASP.NET MVC 3 application. Description: First of all you need to download ASP.NET MVC 3 RTM Source Code from here. Then extract all files in a folder. Then open MvcFutures project from mvc3-rtm-sources\mvc3\src\MvcFutures folder. Build the project. In case, if you get compile time error(s) then simply remove the reference of System.Web.WebPages and System.Web.Mvc assemblies and add the reference of System.Web.WebPages and System.Web.Mvc 3 assemblies again but from the .NET tab and then build the project again, it will create a Microsoft.Web.Mvc assembly inside mvc3-rtm-sources\mvc3\src\MvcFutures\obj\Debug folder. Now we can use Microsoft.Web.Mvc assembly inside our application. Create a new ASP.NET MVC 3 application. For demonstration purpose, I will create a dummy model UserInformation. So create a new class file UserInformation.cs inside Model folder and add the following code, public class UserInformation { [Required] public string Name { get; set; } [Required] [EmailAddress] public string Email { get; set; } [Required] [Url] public string Website { get; set; } [Required] [CreditCard] public string CreditCard { get; set; } [Required] [FileExtensions(Extensions = "jpg,jpeg")] public string Image { get; set; } } Inside UserInformation class, I am using Email, Url, CreditCard and FileExtensions validation attributes which are defined in Microsoft.Web.Mvc assembly. By default FileExtensionsAttribute allows png, jpg, jpeg and gif extensions. You can override this by using Extensions property of FileExtensionsAttribute class. Then just open(or create) HomeController.cs file and add the following code, public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(UserInformation u) { return View(); } } Next just open(or create) Index view for Home controller and add the following code, @model NewValidationAttributesinASPNETMVC3Future.Model.UserInformation @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Index</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>UserInformation</legend> <div class="editor-label"> @Html.LabelFor(model => model.Name) </div> <div class="editor-field"> @Html.EditorFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) </div> <div class="editor-label"> @Html.LabelFor(model => model.Email) </div> <div class="editor-field"> @Html.EditorFor(model => model.Email) @Html.ValidationMessageFor(model => model.Email) </div> <div class="editor-label"> @Html.LabelFor(model => model.Website) </div> <div class="editor-field"> @Html.EditorFor(model => model.Website) @Html.ValidationMessageFor(model => model.Website) </div> <div class="editor-label"> @Html.LabelFor(model => model.CreditCard) </div> <div class="editor-field"> @Html.EditorFor(model => model.CreditCard) @Html.ValidationMessageFor(model => model.CreditCard) </div> <div class="editor-label"> @Html.LabelFor(model => model.Image) </div> <div class="editor-field"> @Html.EditorFor(model => model.Image) @Html.ValidationMessageFor(model => model.Image) </div> <p> <input type="submit" value="Save" /> </p> </fieldset> } <div> @Html.ActionLink("Back to List", "Index") </div> Now just run your application. You will find that both client side and server side validation for the above validation attributes works smoothly. Summary: Email, URL, Credit Card and File Extension input validations are very common. In this article, I showed you how you can validate these input validations into your application. I explained this with an example. I am also attaching a sample application which also includes Microsoft.Web.Mvc.dll. So you can add a reference of Microsoft.Web.Mvc assembly directly instead of doing any manual work. Hope you will enjoy this article too. SyntaxHighlighter.all()

jQuery Templates - XHTML Validation

- by hajan

Many developers have already asked me about this. How to make XHTML valid the web page which uses jQuery Templates. Maybe you have already tried, and I don't know what are your results but here is my opinion regarding this. By default, Visual Studio.NET adds the xhtml1-transitional.dtd schema <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> So, if you try to validate your page which has jQuery Templates against this schema, your page won't be XHTML valid. Why? It's because when creating templates, we use HTML tags inside <script> ... </script> block. Yes, I know that the script block has type="text/html" but it's not supported in this schema, thus it's not valid. Let's try validate the following code Code <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>jQuery Templates :: XHTML Validation</title> <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.min.js" type="text/javascript"></script> <script src="http://ajax.aspnetcdn.com/ajax/jquery.templates/beta1/jquery.tmpl.js" type="text/javascript"></script> <script language="javascript" type="text/javascript"> $(function () { var attendees = [ { Name: "Hajan", Surname: "Selmani", speaker: true, phones: [070555555, 071888999, 071222333] }, { Name: "Denis", Surname: "Manski", phones: [070555555, 071222333] } ]; $("#myTemplate").tmpl(attendees).appendTo("#attendeesList"); }); </script> <script id="myTemplate" type="text/html"> <li> ${Name} ${Surname} {{if speaker}} (<font color="red">speaks</font>) {{else}} (attendee) {{/if}} </li> </script> </head> <body> <ol id="attendeesList"></ol> </body> </html> To validate it, go to http://validator.w3.org/#validate_by_input and copy paste the code rendered on client-side browser (it’s almost the same, only the template is rendered inside OL so LI tags are created for each item). Press CHECK and you will get: Result: 1 Errors, 2 warning(s) The error message says: Validation Output: 1 Error Line 21, Column 13: document type does not allow element "li" here <li> Yes, the <li> HTML element is not allowed inside the <script>, so how to make it valid? FIRST: Using <![CDATA][…]]> The first thing that came in my mind was the CDATA. So, by wrapping any HTML tag which is in script blog, inside <![CDATA[ ........ ]]> it will make our code valid. However, the problem is that the template won't render since the template tags {} cannot get evaluated if they are inside CDATA. Ok, lets try with another approach. SECOND: HTML5 validation Well, if we just remove the strikethrough part bellow of the !DOPCTYPE <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> our template is going to be checked as HTML5 and will be valid. Ok, there is another approach I've also tried: THIRD: Separate template to an external file We can separate the template to external file. I didn’t show how to do this previously, so here is the example. 1. Add HTML file with name Template.html in your ASPX website. 2. Place your defined template there without <script> tag Content inside Template.html <li> ${Name} ${Surname} {{if speaker}} (<font color="red">speaks</font>) {{else}} (attendee) {{/if}} </li> 3. Call the HTML file using $.get() jQuery ajax method and render the template with data using $.tmpl() function. $.get("/Templates/Template.html", function (template) { $.tmpl(template, attendees).appendTo("#attendeesList"); }); So the complete code is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>jQuery Templates :: XHTML Validation</title> <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.min.js" type="text/javascript"></script> <script src="http://ajax.aspnetcdn.com/ajax/jquery.templates/beta1/jquery.tmpl.js" type="text/javascript"></script> <script language="javascript" type="text/javascript"> $(function () { var attendees = [ { Name: "Hajan", Surname: "Selmani", speaker: true, phones: [070555555, 071888999, 071222333] }, { Name: "Denis", Surname: "Manski", phones: [070555555, 071222333] } ]; $.get("/Templates/Template.html", function (template) { $.tmpl(template, attendees).appendTo("#attendeesList"); }); }); </script> </head> <body> <ol id="attendeesList"></ol> </body> </html> This document was successfully checked as XHTML 1.0 Transitional! Result: Passed If you have any additional methods for XHTML validation, you can share it :). Thanks,Hajan

NoSQL with MongoDB, NoRM and ASP.NET MVC - Part 2

- by shiju

In my last post, I have given an introduction to MongoDB and NoRM using an ASP.NET MVC demo app. I have updated the demo ASP.NET MVC app and a created a new drop at codeplex. You can download the demo at http://mongomvc.codeplex.com/In my last post, we have discussed to doing basic CRUD operations against a simple domain entity. In this post, let’s discuss on domain entity with deep object graph.The below is our domain entities public class Category { [MongoIdentifier] public ObjectId Id { get; set; } [Required(ErrorMessage = "Name Required")] [StringLength(25, ErrorMessage = "Must be less than 25 characters")] public string Name { get; set;} public string Description { get; set; } public List<Expense> Expenses { get; set; } public Category() { Expenses = new List<Expense>(); } } public class Expense { [MongoIdentifier] public ObjectId Id { get; set; } public Category Category { get; set; } public string Transaction { get; set; } public DateTime Date { get; set; } public double Amount { get; set; } } We have two domain entities - Category and Expense. A single category contains a list of expense transactions and every expense transaction should have a Category.The MongoSession class internal class MongoSession : IDisposable { private readonly MongoQueryProvider provider; public MongoSession() { this.provider = new MongoQueryProvider("Expense"); } public IQueryable<Category> Categories { get { return new MongoQuery<Category>(this.provider); } } public IQueryable<Expense> Expenses { get { return new MongoQuery<Expense>(this.provider); } } public MongoQueryProvider Provider { get { return this.provider; } } public void Add<T>(T item) where T : class, new() { this.provider.DB.GetCollection<T>().Insert(item); } public void Dispose() { this.provider.Server.Dispose(); } public void Delete<T>(T item) where T : class, new() { this.provider.DB.GetCollection<T>().Delete(item); } public void Drop<T>() { this.provider.DB.DropCollection(typeof(T).Name); } public void Save<T>(T item) where T : class,new() { this.provider.DB.GetCollection<T>().Save(item); } } ASP.NET MVC view model for Expense transaction public class ExpenseViewModel { public ObjectId Id { get; set; } public ObjectId CategoryId { get; set; } [Required(ErrorMessage = "Transaction Required")] public string Transaction { get; set; } [Required(ErrorMessage = "Date Required")] public DateTime Date { get; set; } [Required(ErrorMessage = "Amount Required")] public double Amount { get; set; } public IEnumerable<SelectListItem> Category { get; set; } } Let's create action method for Insert and Update a expense transaction [HttpPost] public ActionResult Save(ExpenseViewModel expenseViewModel) { try { if (!ModelState.IsValid) { using (var session = new MongoSession()) { var categories = session.Categories.AsEnumerable<Category>(); expenseViewModel.Category = categories.ToSelectListItems(expenseViewModel.CategoryId); } return View("Save", expenseViewModel); } var expense=new Expense(); ModelCopier.CopyModel(expenseViewModel, expense); using (var session = new MongoSession()) { ObjectId Id = expenseViewModel.CategoryId; var category = session.Categories .Where(c => c.Id ==Id ) .FirstOrDefault(); expense.Category = category; session.Save(expense); } return RedirectToAction("Index"); } catch { return View(); } } Query with Expenses using (var session = new MongoSession()) { var expenses = session.Expenses. Where(exp => exp.Date >= StartDate && exp.Date <= EndDate) .AsEnumerable<Expense>(); } We are doing a LINQ query expression with a Date filter. We can easily work with MongoDB using NoRM driver and can managing object graph of domain entities are pretty cool.

Part 2: The Customization Lifecycle

- by volker.eckardt(at)oracle.com

To understand the challenges when working with Customizations better, please allow me to explain my understanding from the Customization Lifecycle. The starting point is the functional GAP list. Any GAP can lead to a customization (but not have to). The decision is driven by priority, gain, costs, future functionality, accepted workarounds etc. Let's assume the customization has been accepted as such - including estimation. (Otherwise this blog would not have any value)Now the customization life-cycle starts and could look like this:- Functional specification- Technical specification- Technical development- Functional setup- Module Test- System Test- Integration Test (if required)- Acceptance Test- Production mode- Usage- 10 x Rework- 10 x Retest - 2 x Upgrade- 2 x Upgrade Test- Usage- 10 x Rework- 10 x Retest - 1 x Upgrade- 1 x Upgrade Test- Usage- Review for Retirement- Accepted Retirement- De-installationWhat I like to highlight herewith is that any material and documentation you create upfront or during the first phases will usually be used multiple times, partial or complete, will be enhanced, reviewed, retested. The better the quality right from the beginning is, the better we can perform the next steps.What I see very often is the wish to remove a customization, our customers are upgrading and they like to get at least some of the customizations replaced with standard functionality. To be able to support this process best, the customization documentation should contain at least the following key information: What is/are the business process(es) where this customization is used or linked to?Who was involved in the different customization phases?What are the objects comprising the customization?What is the setup necessary for the customization?What setup comes with the customization, what has to be done via other tools or manually?What are the test steps and test results (in all test areas)?What are linked customizations? What is the customization complexity?How is this customization classified?Which technologies were used?How many days were needed to create/test/upgrade the customization?Etc.If all this is available, a replacement / retirement can be done much more efficient and precise, or an estimation and upgrade itself can be executed with much better support.In the following blog entries I will explain in more detail why we suggest tracking such information, by whom this task shall be done and how.Volker Eckardt

Routes for IIS Classic and Integrated Mode

- by imran_ku07

Introduction: ASP.NET MVC Routing feature makes it very easy to provide clean URLs. You just need to configure routes in global.asax file to create an application with clean URLs. In most cases you define routes works in IIS 6, IIS 7 (or IIS 7.5) Classic and Integrated mode. But in some cases your routes may only works in IIS 7 Integrated mode, like in the case of using extension less URLs in IIS 6 without a wildcard extension map. So in this article I will show you how to create different routes which works in IIS 6 and IIS 7 Classic and Integrated mode. Description: Let's say that you need to create an application which must work both in Classic and Integrated mode. Also you have no control to setup a wildcard extension map in IIS. So you need to create two routes. One with extension less URL for Integrated mode and one with a URL with an extension for Classic Mode. routes.MapRoute( "DefaultClassic", // Route name "{controller}.aspx/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); routes.MapRoute( "DefaultIntegrated", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); Now you have set up two routes, one for Integrated mode and one for Classic mode. Now you only need to ensure that Integrated mode route should only match if the application is running in Integrated mode and Classic mode route should only match if the application is running in Classic mode. For making this work you need to create two custom constraint for Integrated and Classic mode. So replace the above routes with these routes, routes.MapRoute( "DefaultClassic", // Route name "{controller}.aspx/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults new { mode = new ClassicModeConstraint() }// Constraints ); routes.MapRoute( "DefaultIntegrated", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults new { mode = new IntegratedModeConstraint() }// Constraints ); The first route which is for Classic mode adds a ClassicModeConstraint and second route which is for Integrated mode adds a IntegratedModeConstraint. Next you need to add the implementation of these constraint classes. public class ClassicModeConstraint : IRouteConstraint { public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { return !HttpRuntime.UsingIntegratedPipeline; } } public class IntegratedModeConstraint : IRouteConstraint { public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection) { return HttpRuntime.UsingIntegratedPipeline; } } HttpRuntime.UsingIntegratedPipeline returns true if the application is running on Integrated mode; otherwise, it returns false. So routes for Integrated mode only matched when the application is running on Integrated mode and routes for Classic mode only matched when the application is not running on Integrated mode. Summary: During developing applications, sometimes developers are not sure that whether this application will be host on IIS 6 or IIS 7 (or IIS 7.5) Integrated mode or Classic mode. So it's a good idea to create separate routes for both Classic and Integrated mode so that your application will use extension less URLs where possible and use URLs with an extension where it is not possible to use extension less URLs. In this article I showed you how to create separate routes for IIS Integrated and Classic mode. Hope you will enjoy this article too. SyntaxHighlighter.all()

MVVM in Task-It

As I'm gearing up to write a post about dynamic XAP loading with MEF, I'd like to first talk a bit about MVVM, the Model-View-ViewModel pattern, as I will be leveraging this pattern in my future posts. Download Source Code Why MVVM? Your first question may be, "why do I need this pattern? I've been using a code-behind approach for years and it works fine." Well, you really don't have to make the switch to MVVM, but let me first explain some of the benefits I see for doing so. MVVM Benefits Testability - This is the one you'll probably hear the most about when it comes to MVVM. Moving most of the code from your code-behind to a separate view model class means you can now write unit tests against the view model without any knowledge of a view (UserControl). Multiple UIs - Let's just say that you've created a killer app, it's running in the browser, and maybe you've even made it run out-of-browser. Now what if your boss comes to you and says, "I heard about this new Windows Phone 7 device that is coming out later this year. Can you start porting the app to that device?". Well, now you have to create a new UI (UserControls, etc.) because you have a lot less screen real estate to work with. So what do you do, copy all of your existing UserControls, paste them, rename them, and then start changing the code? Hmm, that doesn't sound so good. But wait, if most of the code that makes your browser-based app tick lives in view model classes, now you can create new view (UserControls) for Windows Phone 7 that reference the same view model classes as your browser-based app. Page state - In Silverlight you're at some point going to be faced with the same issue you dealt with for years in ASP.NET, maintaining page state. Let's say a user hits your Products page, does some stuff (filters record, etc.), then leaves the page and comes back later. It would be best if the Products page was in the same state as when they left it right? Well, if you've thrown away your view (UserControl or Page) and moved off to another part of the UI, when you come back to Products you're probably going to re-instantiate your view...which will put it right back in the state it was when it started. Hmm, not good. Well, with a little help from MEF you can store the state in your view model class, MEF will keep that view model instance hanging around in memory, and then you simply rebind your view to the view model class. I made that sound easy, but it's actually a bit of work to properly store and restore the state. At least it can be done though, which will make your users a lot happier! I'll talk more about this in an upcoming blog post. No event handlers? Another nice thing about MVVM is that you can bind your UserControls to the view model, which may eliminate the need for event handlers in your code-behind. So instead of having a Click handler on a Button (or RadMenuItem), for example, you can now bind your control's Command property to a DelegateCommand in your view model (I'll talk more about Commands in an upcoming post). Instead of having a SelectionChanged event handler on your RadGridView you can now bind its SelectedItem property to a property in your view model, and each time the user clicks a row, the view model property's setter will be called. Now through the magic of binding we can eliminate the need for traditional code-behind based event handlers on our user interface controls, and the best thing is that the view model knows about everything that's going on...which means we can test things without a user interface. The brains of the operation So what we're seeing here is that the view is now just a dumb layer that binds to the view model, and that the view model is in control of just about everything, like what happens when a RadGridView row is selected, or when a RadComboBoxItem is selected, or when a RadMenuItem is clicked. It is also responsible for loading data when the page is hit, as well as kicking off data inserts, updates and deletions. Once again, all of this stuff can be tested without the need for a user interface. If the test works, then it'll work regardless of whether the user is hitting the browser-based version of your app, or the Windows Phone 7 version. Nice! The database Before running the code for this app you will need to create the database. First, create a database called MVVMProject in SQL Server, then run MVVMProject.sql in the MVVMProject/Database directory of your downloaded .zip file. This should give you a Task table with 3 records in it. When you fire up the solution you will also need to update the connection string in web.config to point to your database instead of IBM12\SQLSERVER2008. The code One note about this code is that it runs against the latest Silverlight 4 RC and WCF RIA Services code. Please see my first blog post about updating to the RC bits. Beta to RC - Part 1 At the top of this post is a link to a sample project that demonstrates a sample application with a Tasks page that uses the MVVM pattern. This is a simplified version of how I have implemented the Tasks page in the Task-It application. Youll notice that Tasks.xaml has very little code to it. Just a TextBlock that displays the page title and a ContentControl. <StackPanel> <TextBlock Text="Tasks" Style="{StaticResource PageTitleStyle}"/> <Rectangle Style="{StaticResource StandardSpacerStyle}"/> <ContentControl x:Name="ContentControl1"/> </StackPanel> In List.xaml we have a RadGridView. Notice that the ItemsSource is bound to a property in the view model class call Tasks, SelectedItem is bound to a property in the view model called SelectedItem, and IsBusy is bound to a property in the view model called IsLoading. <Grid> <telerikGridView:RadGridView ItemsSource="{Binding Tasks}" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" IsBusy="{Binding IsLoading}" AutoGenerateColumns="False" IsReadOnly="True" RowIndicatorVisibility="Collapsed" IsFilteringAllowed="False" ShowGroupPanel="False"> <telerikGridView:RadGridView.Columns> <telerikGridView:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}" Width="3*"/> <telerikGridView:GridViewDataColumn Header="Due" DataMemberBinding="{Binding DueDate}" DataFormatString="{}{0:d}" Width="*"/> </telerikGridView:RadGridView.Columns> </telerikGridView:RadGridView> </Grid> In Details.xaml we have a Save button that is bound to a property called SaveCommand in our view model. We also have a simple form (Im using a couple of controls here from Silverlight.FX for the form layout, FormPanel and Label simply because they make for a clean XAML layout). Notice that the FormPanel is also bound to the SelectedItem in the view model (the same one that the RadGridView is). The two form controls, the TextBox and RadDatePicker) are bound to the SelectedItem's Name and DueDate properties. These are properties of the Task object that WCF RIA Services creates. <StackPanel> <Button Content="Save" Command="{Binding SaveCommand}" HorizontalAlignment="Left"/> <Rectangle Style="{StaticResource StandardSpacerStyle}"/> <fxui:FormPanel DataContext="{Binding SelectedItem}" Style="{StaticResource FormContainerStyle}"> <fxui:Label Text="Name:"/> <TextBox Text="{Binding Name, Mode=TwoWay}"/> <fxui:Label Text="Due:"/> <telerikInput:RadDatePicker SelectedDate="{Binding DueDate, Mode=TwoWay}"/> </fxui:FormPanel> </StackPanel> In the code-behind of the Tasks control, Tasks.xaml.cs, I created an instance of the view model class (TasksViewModel) in the constructor and set it as the DataContext for the control. The Tasks page will load one of two child UserControls depending on whether you are viewing the list of tasks (List.xaml) or the form for editing a task (Details.xaml). // Set the DataContext to an instance of the view model class var viewModel = new TasksViewModel(); DataContext = viewModel; // Child user controls (inherit DataContext from this user control) List = new List(); // RadGridView Details = new Details(); // Form When the page first loads, the List is loaded into the ContentControl. // Show the RadGridView first ContentControl1.Content = List; In the code-behind we also listen for a couple of the view models events. The ItemSelected event will be fired when the user clicks on a record in the RadGridView in the List control. The SaveCompleted event will be fired when the user clicks Save in the Details control (the form). Here the view model is in control, and is letting the view know when something needs to change. // Listeners for the view model's events viewModel.ItemSelected += OnItemSelected; viewModel.SaveCompleted += OnSaveCompleted; The event handlers toggle the view between the RadGridView (List) and the form (Details). void OnItemSelected(object sender, RoutedEventArgs e) { // Show the form ContentControl1.Content = Details; } void OnSaveCompleted(object sender, RoutedEventArgs e) { // Show the RadGridView ContentControl1.Content = List; } In TasksViewModel, we instantiate a DataContext object and a SaveCommand in the constructor. DataContext is a WCF RIA Services object that well use to retrieve the list of Tasks and to save any changes to a task. Ill talk more about this and Commands in future post, but for now think of the SaveCommand as an event handler that is called when the Save button in the form is clicked. DataContext = new DataContext(); SaveCommand = new DelegateCommand(OnSave); When the TasksViewModel constructor is called we also make a call to LoadTasks. This sets IsLoading to true (which causes the RadGridViews busy indicator to appear) and retrieves the records via WCF RIA Services. public LoadOperation<Task> LoadTasks() { // Show the loading message IsLoading = true; // Get the data via WCF RIA Services. When the call has returned, called OnTasksLoaded. return DataContext.Load(DataContext.GetTasksQuery(), OnTasksLoaded, false); } When the data is returned, OnTasksLoaded is called. This sets IsLoading to false (which hides the RadGridViews busy indicator), and fires property changed notifications to the UI to let it know that the IsLoading and Tasks properties have changed. This property changed notification basically tells the UI to rebind. void OnTasksLoaded(LoadOperation<Task> lo) { // Hide the loading message IsLoading = false; // Notify the UI that Tasks and IsLoading properties have changed this.OnPropertyChanged(p => p.Tasks); this.OnPropertyChanged(p => p.IsLoading); } Next lets look at the view models SelectedItem property. This is the one thats bound to both the RadGridView and the form. When the user clicks a record in the RadGridView its setter gets called (set a breakpoint and see what I mean). The other code in the setter lets the UI know that the SelectedItem has changed (so the form displays the correct data), and fires the event that notifies the UI that a selection has occurred (which tells the UI to switch from List to Details). public Task SelectedItem { get { return _selectedItem; } set { _selectedItem = value; // Let the UI know that the SelectedItem has changed (forces it to re-bind) this.OnPropertyChanged(p => p.SelectedItem); // Notify the UI, so it can switch to the Details (form) page NotifyItemSelected(); } } One last thing, saving the data. When the Save button in the form is clicked it fires the SaveCommand, which calls the OnSave method in the view model (once again, set a breakpoint to see it in action). public void OnSave() { // Save the changes via WCF RIA Services. When the save is complete, call OnSaveCompleted. DataContext.SubmitChanges(OnSaveCompleted, null); } In OnSave, we tell WCF RIA Services to submit any changes, which there will be if you changed either the Name or the Due Date in the form. When the save is completed, it calls OnSaveCompleted. This method fires a notification back to the UI that the save is completed, which causes the RadGridView (List) to show again. public virtual void OnSaveCompleted(SubmitOperation so) { // Clear the item that is selected in the grid (in case we want to select it again) SelectedItem = null; // Notify the UI, so it can switch back to the List (RadGridView) page NotifySaveCompleted(); } Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

Automating Solaris 11 Zones Installation Using The Automated Install Server

- by Orgad Kimchi

Introduction How to use the Oracle Solaris 11 Automated install server in order to automate the Solaris 11 Zones installation. In this document I will demonstrate how to setup the Automated Install server in order to provide hands off installation process for the Global Zone and two Non Global Zones located on the same system. Architecture layout: Figure 1. Architecture layout Prerequisite Setup the Automated install server (AI) using the following instructions “How to Set Up Automated Installation Services for Oracle Solaris 11” The first step in this setup will be creating two Solaris 11 Zones configuration files. Step 1: Create the Solaris 11 Zones configuration files The Solaris Zones configuration files should be in the format of the zonecfg export command. # zonecfg -z zone1 export > /var/tmp/zone1# cat /var/tmp/zone1 create -b set brand=solaris set zonepath=/rpool/zones/zone1 set autoboot=true set ip-type=exclusive add anet set linkname=net0 set lower-link=auto set configure-allowed-address=true set link-protection=mac-nospoof set mac-address=random end Create a backup copy of this file under a different name, for example, zone2. # cp /var/tmp/zone1 /var/tmp/zone2 Modify the second configuration file with the zone2 configuration information You should change the zonepath for example: set zonepath=/rpool/zones/zone2 Step2: Copy and share the Zones configuration files Create the NFS directory for the Zones configuration files # mkdir /export/zone_config Share the directory for the Zones configuration file # share –o ro /export/zone_config Copy the Zones configuration files into the NFS shared directory # cp /var/tmp/zone1 /var/tmp/zone2 /export/zone_config Verify that the NFS share has been created using the following command # share export_zone_config /export/zone_config nfs sec=sys,ro Step 3: Add the Global Zone as client to the Install Service Use the installadm create-client command to associate client (Global Zone) with the install service To find the MAC address of a system, use the dladm command as described in the dladm(1M) man page. The following command adds the client (Global Zone) with MAC address 0:14:4f:2:a:19 to the s11x86service install service. # installadm create-client -e “0:14:4f:2:a:19" -n s11x86service You can verify the client creation using the following command # installadm list –c Service Name Client Address Arch Image Path ------------ -------------- ---- ---------- s11x86service 00:14:4F:02:0A:19 i386 /export/auto_install/s11x86service We can see the client install service name (s11x86service), MAC address (00:14:4F:02:0A:19 and Architecture (i386). Step 4: Global Zone manifest setup First, get a list of the installation services and the manifests associated with them: # installadm list -m Service Name Manifest Status ------------ -------- ------ default-i386 orig_default Default s11x86service orig_default Default Then probe the s11x86service and the default manifest associated with it. The -m switch reflects the name of the manifest associated with a service. Since we want to capture that output into a file, we redirect the output of the command as follows: # installadm export -n s11x86service -m orig_default > /var/tmp/orig_default.xml Create a backup copy of this file under a different name, for example, orig-default2.xml, and edit the copy. # cp /var/tmp/orig_default.xml /var/tmp/orig_default2.xml Use the configuration element in the AI manifest for the client system to specify non-global zones. Use the name attribute of the configuration element to specify the name of the zone. Use the source attribute to specify the location of the config file for the zone.The source location can be any http:// or file:// location that the client can access during installation. The following sample AI manifest specifies two Non-Global Zones: zone1 and zone2 You should replace the server_ip with the ip address of the NFS server. <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install> <ai_instance> <target> <logical> <zpool name="rpool" is_root="true"> <filesystem name="export" mountpoint="/export"/> <filesystem name="export/home"/> <be name="solaris"/> </zpool> </logical> </target> <software type="IPS"> <source> <publisher name="solaris"> <origin name="http://pkg.oracle.com/solaris/release"/> </publisher> </source> <software_data action="install"> <name>pkg:/entire@latest</name> <name>pkg:/group/system/solaris-large-server</name> </software_data> </software> <configuration type="zone" name="zone1" source="file:///net/server_ip/export/zone_config/zone1"/> <configuration type="zone" name="zone2" source="file:///net/server_ip/export/zone_config/zone2"/> </ai_instance> </auto_install> The following example adds the /var/tmp/orig_default2.xml AI manifest to the s11x86service install service # installadm create-manifest -n s11x86service -f /var/tmp/orig_default2.xml -m gzmanifest You can verify the manifest creation using the following command # installadm list -n s11x86service -m Service/Manifest Name Status Criteria --------------------- ------ -------- s11x86service orig_default Default None gzmanifest Inactive None We can see from the command output that the new manifest named gzmanifest has been created and associated with the s11x86service install service. Step 5: Non Global Zone manifest setup The AI manifest for non-global zone installation is similar to the AI manifest for installing the global zone. If you do not provide a custom AI manifest for a non-global zone, the default AI manifest for Zones is used The default AI manifest for Zones is available at /usr/share/auto_install/manifest/zone_default.xml. In this example we should use the default AI manifest for zones The following sample default AI manifest for zones # cat /usr/share/auto_install/manifest/zone_default.xml <?xml version="1.0" encoding="UTF-8"?>  <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install> <ai_instance name="zone_default"> <target> <logical> <zpool name="rpool">  <filesystem name="export" mountpoint="/export"/> <filesystem name="export/home"/> <be name="solaris"> <options> <option name="compression" value="on"/> </options> </be> </zpool> </logical> </target> <software type="IPS"> <destination> <image>  <facet set="false">facet.locale.*</facet> <facet set="true">facet.locale.de</facet> <facet set="true">facet.locale.de_DE</facet> <facet set="true">facet.locale.en</facet> <facet set="true">facet.locale.en_US</facet> <facet set="true">facet.locale.es</facet> <facet set="true">facet.locale.es_ES</facet> <facet set="true">facet.locale.fr</facet> <facet set="true">facet.locale.fr_FR</facet> <facet set="true">facet.locale.it</facet> <facet set="true">facet.locale.it_IT</facet> <facet set="true">facet.locale.ja</facet> <facet set="true">facet.locale.ja_*</facet> <facet set="true">facet.locale.ko</facet> <facet set="true">facet.locale.ko_*</facet> <facet set="true">facet.locale.pt</facet> <facet set="true">facet.locale.pt_BR</facet> <facet set="true">facet.locale.zh</facet> <facet set="true">facet.locale.zh_CN</facet> <facet set="true">facet.locale.zh_TW</facet> </image> </destination> <software_data action="install"> <name>pkg:/group/system/solaris-small-server</name> </software_data> </software> </ai_instance> </auto_install> (optional) We can customize the default AI manifest for Zones Create a backup copy of this file under a different name, for example, zone_default2.xml and edit the copy # cp /usr/share/auto_install/manifest/zone_default.xml /var/tmp/zone_default2.xml Edit the copy (/var/tmp/zone_default2.xml) The following example adds the /var/tmp/zone_default2.xml AI manifest to the s11x86service install service and specifies that zone1 and zone2 should use this manifest. # installadm create-manifest -n s11x86service -f /var/tmp/zone_default2.xml -m zones_manifest -c zonename="zone1 zone2" Note: Do not use the following elements or attributes in a non-global zone AI manifest: The auto_reboot attribute of the ai_instance element The http_proxy attribute of the ai_instance element The disk child element of the target element The noswap attribute of the logical element The nodump attribute of the logical element The configuration element Step 6: Global Zone profile setup We are going to create a global zone configuration profile which includes the host information for example: host name, ip address name services etc… # sysconfig create-profile –o /var/tmp/gz_profile.xml You need to provide the host information for example: Default router Root password DNS information The output should eventually disappear and be replaced by the initial screen of the System Configuration Tool (see Figure 2), where you can do the final configuration. Figure 2. Profile creation menu You can validate the profile using the following command # installadm validate -n s11x86service –P /var/tmp/gz_profile.xml Validating static profile gz_profile.xml... Passed Next, instantiate a profile with the install service. In our case, use the following syntax for doing this # installadm create-profile -n s11x86service -f /var/tmp/gz_profile.xml -p gz_profile You can verify profile creation using the following command # installadm list –n s11x86service -p Service/Profile Name Criteria -------------------- -------- s11x86service gz_profile None We can see that the gz_profie has been created and associated with the s11x86service Install service. Step 7: Setup the Solaris Zones configuration profiles The step should be similar to the Global zone profile creation on step 6 # sysconfig create-profile –o /var/tmp/zone1_profile.xml # sysconfig create-profile –o /var/tmp/zone2_profile.xml You can validate the profiles using the following command # installadm validate -n s11x86service -P /var/tmp/zone1_profile.xml Validating static profile zone1_profile.xml... Passed # installadm validate -n s11x86service -P /var/tmp/zone2_profile.xml Validating static profile zone2_profile.xml... Passed Next, associate the profiles with the install service The following example adds the zone1_profile.xml configuration profile to the s11x86service install service and specifies that zone1 should use this profile. # installadm create-profile -n s11x86service -f /var/tmp/zone1_profile.xml -p zone1_profile -c zonename=zone1 The following example adds the zone2_profile.xml configuration profile to the s11x86service install service and specifies that zone2 should use this profile. # installadm create-profile -n s11x86service -f /var/tmp/zone2_profile.xml -p zone2_profile -c zonename=zone2 You can verify the profiles creation using the following command # installadm list -n s11x86service -p Service/Profile Name Criteria -------------------- -------- s11x86service zone1_profile zonename = zone1 zone2_profile zonename = zone2 gz_profile None We can see that we have three profiles in the s11x86service install service Global Zone gz_profile zone1 zone1_profile zone2 zone2_profile. Step 8: Global Zone setup Associate the global zone client with the manifest and the profile that we create in the previous steps The following example adds the manifest and profile to the client (global zone), where: gzmanifest is the name of the manifest. gz_profile is the name of the configuration profile. mac="0:14:4f:2:a:19" is the client (global zone) mac address s11x86service is the install service name. # installadm set-criteria -m gzmanifest –p gz_profile -c mac="0:14:4f:2:a:19" -n s11x86service You can verify the manifest and profile association using the following command # installadm list -n s11x86service -p -m Service/Manifest Name Status Criteria --------------------- ------ -------- s11x86service gzmanifest mac = 00:14:4F:02:0A:19 orig_default Default None Service/Profile Name Criteria -------------------- -------- s11x86service gz_profile mac = 00:14:4F:02:0A:19 zone2_profile zonename = zone2 zone1_profile zonename = zone1 Step 9: Provision the host with the Non-Global Zones The next step is to boot the client system off the network and provision it using the Automated Install service that we just set up. First, boot the client system. Figure 3 shows the network boot attempt (when done on an x86 system): Figure 3. Network Boot Then you will be prompted by a GRUB menu, with a timer, as shown in Figure 4. The default selection (the "Text Installer and command line" option) is highlighted. Press the down arrow to highlight the second option labeled Automated Install, and then press Enter. The reason we need to do this is because we want to prevent a system from being automatically re-installed if it were to be booted from the network accidentally. Figure 4. GRUB Menu What follows is the continuation of a networked boot from the Automated Install server,. The client downloads a mini-root (a small set of files in which to successfully run the installer), identifies the location of the Automated Install manifest on the network, retrieves that manifest, and then processes it to identify the address of the IPS repository from which to obtain the desired software payload. Non-Global Zones are installed and configured on the first reboot after the Global Zone is installed. You can list all the Solaris Zones status using the following command # zoneadm list -civ Once the Zones are in running state you can login into the Zone using the following command # zlogin –z zone1 Troubleshooting Automated Installations If an installation to a client system failed, you can find the client log at /system/volatile/install_log. NOTE: Zones are not installed if any of the following errors occurs: A zone config file is not syntactically correct. A collision exists among zone names, zone paths, or delegated ZFS datasets in the set of zones to be installed Required datasets are not configured in the global zone. For more troubleshooting information see “Installing Oracle Solaris 11 Systems” Conclusion This paper demonstrated the benefits of using the Automated Install server to simplify the Non Global Zones setup, including the creation and configuration of the global zone manifest and the Solaris Zones profiles.

Retrieving only the first record or record at a certain index in LINQ

- by vik20000in

While working with data it’s not always required that we fetch all the records. Many a times we only need to fetch the first record, or some records in some index, in the record set. With LINQ we can get the desired record very easily with the help of the provided element operators. Simple get the first record. If you want only the first record in record set we can use the first method [Note that this can also be done easily done with the help of the take method by providing the value as one]. List<Product> products = GetProductList(); Product product12 = ( from prod in products where prod.ProductID == 12 select prod) .First(); We can also very easily put some condition on which first record to be fetched. string[] strings = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; string startsWithO = strings.First(s => s[0] == 'o'); In the above example the result would be “one” because that is the first record starting with “o”. Also the fact that there will be chances that there are no value returned in the result set. When we know such possibilities we can use the FirstorDefault() method to return the first record or incase there are no records get the default value. int[] numbers = {}; int firstNumOrDefault = numbers.FirstOrDefault(); In case we do not want the first record but the second or the third or any other later record then we can use the ElementAt() method. In the ElementAt() method we need to pass the index number for which we want the record and we will receive the result for that element. int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; int fourthLowNum = ( from num in numbers where num > 5 select num ) .ElementAt(1); Vikram

Alert visualization recipe: Get out your blender, drop in some sp_send_dbmail, Google Charts API, add your favorite colors and sprinkle with html. Blend till it’s smooth and looks pretty enough to taste.

- by Maria Zakourdaev

I really like database monitoring. My email inbox have a constant flow of different types of alerts coming from our production servers with all kinds of information, sometimes more useful and sometimes less useful. Usually database alerts look really simple, it’s usually a plain text email saying “Prod1 Database data file on Server X is 80% used. You’d better grow it manually before some query triggers the AutoGrowth process”. Imagine you could have received email like the one below. In addition to the alert description it could have also included the the database file growth chart over the past 6 months. Wouldn’t it give you much more information whether the data growth is natural or extreme? That’s truly what data visualization is for. Believe it or not, I have sent the graph below from SQL Server stored procedure without buying any additional data monitoring/visualization tool. Would you like to visualize your database alerts like I do? Then like myself, you’d love the Google Charts. All you need to know is a little HTML and have a mail profile configured on your SQL Server instance regardless of the SQL Server version. First of all, I hope you know that the sp_send_dbmail procedure has a great parameter @body_format = ‘HTML’, which allows us to send rich and colorful messages instead of boring black and white ones. All that we need is to dynamically create HTML code. This is how, for instance, you can create a table and populate it with some data: DECLARE @html varchar(max) SET @html = '<html>' + '<H3><font id="Text" style='color: Green;'>Top Databases: </H3>' + '<table border="1" bordercolor="#3300FF" style='background-color:#DDF8CC' width='70%' cellpadding='3' cellspacing='3'>' + '<tr><font color="Green"><th>Database Name</th><th>Size</th><th>Physical Name</th></tr>' + CAST( (SELECT TOP 10 td = name,'', td = size * 8/1024 ,'', td = physical_name FROM sys.master_files ORDER BY size DESC FOR XML PATH ('tr'),TYPE ) AS VARCHAR(MAX)) + '</table>' EXEC msdb.dbo.sp_send_dbmail @recipients = '[email protected]', @subject ='Top databases', @body = @html, @body_format = 'HTML' This is the result: If you want to add more visualization effects, you can use Google Charts Tools https://google-developers.appspot.com/chart/interactive/docs/index which is a free and rich library of data visualization charts, they’re also easy to populate and embed. There are two versions of the Google Charts Image based charts: https://google-developers.appspot.com/chart/image/docs/gallery/chart_gall This is an old version, it’s officially deprecated although it will be up for a next few years or so. I really enjoy using this one because it can be viewed within the email body. For mobile devices you need to change the “Load remote images” property in your email application configuration. Charts based on JavaScript classes: https://google-developers.appspot.com/chart/interactive/docs/gallery This API is newer, with rich and highly interactive charts, and it’s much more easier to understand and configure. The only downside of it is that they cannot be viewed within the email body. Outlook, Gmail and many other email clients, as part of their security policy, do not run any JavaScript that’s placed within the email body. However, you can still enjoy this API by sending the report as an email attachment. Here is an example of the old version of Google Charts API, sending the same top databases report as in the previous example but instead of a simple table, this script is using a pie chart right from the T-SQL code DECLARE @html varchar(8000) DECLARE @Series varchar(800),@Labels varchar(8000),@Legend varchar(8000); SET @Series = ''; SET @Labels = ''; SET @Legend = ''; SELECT TOP 5 @Series = @Series + CAST(size * 8/1024 as varchar) + ',', @Labels = @Labels +CAST(size * 8/1024 as varchar) + 'MB'+'|', @Legend = @Legend + name + '|' FROM sys.master_files ORDER BY size DESC SELECT @Series = SUBSTRING(@Series,1,LEN(@Series)-1), @Labels = SUBSTRING(@Labels,1,LEN(@Labels)-1), @Legend = SUBSTRING(@Legend,1,LEN(@Legend)-1) SET @html = '<H3><font color="Green"> '+@@ServerName+' top 5 databases : </H3>'+ '<br>'+ '<img src="http://chart.apis.google.com/chart?'+ 'chf=bg,s,DDF8CC&'+ 'cht=p&'+ 'chs=400x200&'+ 'chco=3072F3|7777CC|FF9900|FF0000|4A8C26&'+ 'chd=t:'+@Series+'&'+ 'chl='+@Labels+'&'+ 'chma=0,0,0,0&'+ 'chdl='+@Legend+'&'+ 'chdlp=b"'+ 'alt="'+@@ServerName+' top 5 databases" />' EXEC msdb.dbo.sp_send_dbmail @recipients = '[email protected]', @subject = 'Top databases', @body = @html, @body_format = 'HTML' This is what you get.

It's not just “Single Sign-on” by Steve Knott (aurionPro SENA)

- by Greg Jensen

It is true that Oracle Enterprise Single Sign-on (Oracle ESSO) started out as purely an application single sign-on tool but as we have seen in the previous articles in this series the product has matured into a suite of tools that can do more than just automated single sign-on and can also provide rapidly deployed, cost effective solution to many demanding password management problems. In the last article of this series I would like to discuss three cases where customers faced password scenarios that required more than just single sign-on and how some of the less well known tools in the Oracle ESSO suite “kitbag” helped solve these challenges. Case #1 One of the issues often faced by our customers is how to keep their applications compliant. I had a client who liked the idea of automated single sign-on for most of his applications but had a key requirement to actually increase the security for one specific SOX application. For the SOX application he wanted to secure access by using two-factor authentication with a smartcard. The problem was that the application did not support two-factor authentication. The solution was to use a feature from the Oracle ESSO suite called authentication manager. This feature enables you to have multiple authentication methods for the same user which in this case was a smartcard and the Windows password. Within authentication manager each authenticator can be configured with a security grade so we gave the smartcard a high grade and the Windows password a normal grade. Security grading in Oracle ESSO can be configured on a per application basis so we set the SOX application to require the higher grade smartcard authenticator. The end result for the user was that they enjoyed automated single sign-on for most of the applications apart from the SOX application. When the SOX application was launched, the user was required by ESSO to present their smartcard before being given access to the application. Case #2 Another example solving compliance issues was in the case of a large energy company who had a number of core billing applications. New regulations required that users change their password regularly and use a complex password. The problem facing the customer was that the core billing applications did not have any native user password change functionality. The customer could not replace the core applications because of the cost and time required to re-develop them. With a reputation for innovation aurionPro SENA were approached to provide a solution to this problem using Oracle ESSO. Oracle ESSO has a password expiry feature that can be triggered periodically based on the timestamp of the users’ last password creation therefore our strategy here was to leverage this feature to provide the password change experience. The trigger can launch an application change password event however in this scenario there was no native change password feature that could be launched therefore a “dummy” change password screen was created that could imitate the missing change password function and connect to the application database on behalf of the user. Oracle ESSO was configured to trigger a change password event every 60 days. After this period if the user launched the application Oracle ESSO would detect the logon screen and invoke the password expiry feature. Oracle ESSO would trigger the “dummy screen,” detect it automatically as the application change password screen and insert a complex password on behalf of the user. After the password event had completed the user was logged on to the application with their new password. All this was provided at a fraction of the cost of re-developing the core applications. Case #3 Recent popular initiatives such as the BYOD and working from home schemes bring with them many challenges in administering “unmanaged machines” and sometimes “unmanageable users.” In a recent case, a client had a dispersed community of casual contractors who worked for the business using their own laptops to access applications. To improve security the around password management the security goal was to provision the passwords directly to these contractors. In a previous article we saw how Oracle ESSO has the capability to provision passwords through Provisioning Gateway but the challenge in this scenario was how to get the Oracle ESSO agent to the casual contractor on an unmanaged machine. The answer was to use another tool in the suite, Oracle ESSO Anywhere. This component can compile the normal Oracle ESSO functionality into a deployment package that can be made available from a website in a similar way to a streamed application. The ESSO Anywhere agent does not actually install into the registry or program files but runs in a folder within the user’s profile therefore no local administrator rights are required for installation. The ESSO Anywhere package can also be configured to stay persistent or disable itself at the end of the user’s session. In this case the user just needed to be told where the website package was located and download the package. Once the download was complete the agent started automatically and the user was provided with single sign-on to their applications without ever knowing the application passwords. Finally, as we have seen in these series Oracle ESSO not only has great utilities in its own tool box but also has direct integration with Oracle Privileged Account Manager, Oracle Identity Manager and Oracle Access Manager. Integrated together with these tools provides a complete and complementary platform to address even the most complex identity and access management requirements. So what next for Oracle ESSO? “Agentless ESSO available in the cloud” – but that will be a subject for a future Oracle ESSO series!
