• SQL SERVER – Video – Beginning Performance Tuning with SQL Server Execution Plan

  - by pinaldave

  Traveling can be most interesting or most exhausting experience. However, traveling is always the most enlightening experience one can have. While going to long journey one has to prepare a lot of things. Pack necessary travel gears, clothes and medicines. However, the most essential part of travel is the journey to the destination. There are many variations one prefer but the ultimate goal is to have a delightful experience during the journey. Here is the video available which explains how to begin with SQL Server Execution plans. Performance Tuning is a Journey Performance tuning is just like a long journey. The goal of performance tuning is efficient and least resources consuming query execution with accurate results. Just as maps are the most essential aspect of performance tuning the same way, execution plans are essentially maps for SQL Server to reach to the resultset. The goal of the execution plan is to find the most efficient path which translates the least usage of the resources (CPU, memory, IO etc). Execution Plans are like Maps When online maps were invented (e.g. Bing, Google, Mapquests etc) initially it was not possible to customize them. They were given a single route to reach to the destination. As time evolved now it is possible to give various hints to the maps, for example ‘via public transport’, ‘walking’, ‘fastest route’, ‘shortest route’, ‘avoid highway’. There are places where we manually drag the route and make it appropriate to our needs. The same situation is with SQL Server Execution Plans, if we want to tune the queries, we need to understand the execution plans and execution plans internals. We need to understand the smallest details which relate to execution plan when we our destination is optimal queries. Understanding Execution Plans The biggest challenge with maps are figuring out the optimal path. The same way the  most common challenge with execution plans is where to start from and which precise route to take. Here is a quick list of the frequently asked questions related to execution plans: Should I read the execution plans from bottoms up or top down? Is execution plans are left to right or right to left? What is the relational between actual execution plan and estimated execution plan? When I mouse over operator I see CPU and IO but not memory, why? Sometime I ran the query multiple times and I get different execution plan, why? How to cache the query execution plan and data? I created an optimal index but the query is not using it. What should I change – query, index or provide hints? What are the tools available which helps quickly to debug performance problems? Etc… Honestly the list is quite a big and humanly impossible to write everything in the words. SQL Server Performance:  Introduction to Query Tuning My friend Vinod Kumar and I have created for the same a video learning course for beginning performance tuning. We have covered plethora of the subject in the course. Here is the quick list of the same: Execution Plan Basics Essential Indexing Techniques Query Design for Performance Performance Tuning Tools Tips and Tricks Checklist: Performance Tuning We believe we have covered a lot in this four hour course and we encourage you to go over the video course if you are interested in Beginning SQL Server Performance Tuning and Query Tuning.

• SOA 10g Developing a Simple Hello World Process

  - by [email protected]

  Softwares & Hardware Needed Intel Pentium D CPU 3 GHz, 2 GB RAM, Windows XP System ( Thats what i am using ) You could as well use Linux , but please choose High End RAM 10G SOA Suite from Oracle(TM) , Read Installation documents at www.Oracle.com J Developer 10.1.3.3 Official Documents at http://www.oracle.com/technology/products/ias/bpel/index.html java -version Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)BPEL Introduction - Developing a Simple Hello World Process  Synchronous BPEL Process      This Exercise focuses on developing a Synchronous Process, which mean you give input to the BPEL Process you get output immediately no waiting at all. The Objective of this exercise is to give input as name and it greets with Hello Appended by that name example, if I give input as "James" the BPEL process returns "Hello James". 1. Open the Oracle JDeveloper click on File -> New Application give the name "JamesApp" you can give your own name if it pleases you. Select the folder where you want to place the application. Click "OK" 2. Right Click on the "JamesApp" in the Application Navigator, Select New Menu. 3. Select "Projects" under "General" and "BPEL Process Project", click "OK" these steps remain same for all BPEL Projects 4. Project Setting Wizard Appears, Give the "Process Name" as "MyBPELProc" and Namespace as http://xmlns.james.com/ MyBPELProc, Select Template as "Synchronous BPEL Process click "Next" 5. Accept the input and output schema names as it is, click "Finish" 6. You would see the BPEL Process Designer, some of the folders such as Integration content and Resources are created and few more files 7. Assign Activity : Allows Assigning values to variables or copying values of one variable to another and also do some string manipulation or mathematical operations In the component palette at extreme right, select Process Activities from the drop down, and drag and drop "Assign" between "receive Input" and "replyOutput" 8. You can right click and edit the Assign activity and give any suitable name "AssignHello", 9. Select "Copy Operation" Tab create "Copy Operation" 10. In the From variables click on expression builder, select input under "input variable", Click on insert into expression bar, complete the concat syntax, Note to use "Ctrl+space bar" inside expression window to Auto Populate the expression as shown in the figure below. What we are actually doing here is concatenating the String "Hello ", with the variable value received through the variable named "input" 11. Observe that once an expression is completed the "To Variable" is assigned to a variable by name "result" 12. Finally the copy variable looks as below 13. It's the time to deploy, start the SOA Suite 14. Establish connection to the Server from JDeveloper, this can be done adding a New Application Server under Connection, give the server name, username and password and test connection. 15. Deploy the "MyBPELProc" to the "default domain" 16. http://localhost:8080/ allows connecting to SOA Suite web portal, click on "BPEL Control" , login with the username "oc4jadmin" password what ever you gave during installation 17. "MyBPELProc" is visisble under "Deployed BPEL Processes" in the "Dashboard" Tab, click on the it 18. Initiate tab open to accept input, enter data such as input is "James" click on "Post XML Button" 19. Click on Visual Flow 20. Click on receive Input , it shows "James" as input received 21. Click on reply Output, it shows "Hello James" so the BPEL process is successfully executed. 22. It may be worth seeing all the instance created everytime a BPEL process is executed by giving some inputs. Purge All button allows to delete all the unwanted previous instances of BPEL process, dont worry it wont delete the BPEL process itself :-) 23. It may also be some importance to understand the XSD File which holds input & output variable names & data types. 24. You could drag n drop variables as elements over sequence at the designer or directly edit the XML Source file.

• Screen Scraping Twitter

  - by BRADINO

  I got an email today asking for help to scrape Twitter. In particular, to be able to login. So I am going to show everyone, NOT to encourage anyone to violate Twitters terms of use but as an educational blog post about how PHP and cURL can be used to post variables and store cookies. Again, I am using the cScrape class I wrote, which you can download. Step 1 First go to twitter.com and look at the source code of the login to get the form field names and the form post location. You will see that the form posts to https://twitter.com/session and the username and password fields are session[username_or_email] and session[password] respectively. Step 2 Now you are ready to login. So using the fetch function in the Scrape class you create an associative array to contain the form values you want to post. The other thing you will need to do is uncomment the lines for CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR. Cookies will be required to stay logged in and scrape around. The paths to the cookie files need to be writable by your app. Also you will need to uncomment the line about CURLOPT_FOLLOWLOCATION. $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $scrape->fetch('https://twitter.com/sessions',$data); Step 1.5 Oops that didn't work. All I got back was 403 Forbidden: The server understood the request, but is refusing to fulfill it. Ahhh I see another variable called authenticity_token I bet Twitter was looking for that. So let's back up and first hit twitter.com to get the authenticity_token variable, and then make the login post request with that variable included in our array of parameters. $scrape->fetch('https://twitter.com'); $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $data['authenticity_token'] = $scrape->fetchBetween('name="authenticity_token" type="hidden" value="','"',$scrape->result); $scrape->fetch('https://twitter.com/sessions',$data); echo $scrape->result; So that's basically it. Now you are logged in and can scrape around and request other pages as you normally would. Sorry it wasn't a longer post. I really do enjoy this kind of stuff so if anyone has a request, hit me up. Errors? 1) Make sure that you are properly parsing the token variable 2) Make sure that you uncommented the lines about CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR, those options need to be enabled and be sure the path set is writable by your application 3) Make sure that the path to the cookie file is writable and that it is getting data written to it 4) If you get a message about being redirected you need to uncomment the line about CURLOPT_FOLLOWLOCATION, that option needs to be enabled true

• DevConnections Slides and Samples Posted

  - by Rick Strahl

  I’ve posted the slides and samples to my DevConnections Sessions for anyone interested. I had a lot of fun with my sessions this time around mainly because the sessions picked were a little off the beaten track (well, the handlers/modules and e-commerce sessions anyway). For those of you that attended I hope you found the sessions useful. For the rest of you – you can check out the slides and samples if you like. Here’s what was covered: Introduction to jQuery with ASP.NET This session covered mostly the client side of jQuery demonstrated on a small sample page with a variety of incrementally built up examples of selection and page manipulation. This session also introduces some of the basics of AJAX communication talking to ASP.NET. When I do this session it never turns out exactly the same way and this time around the examples were on the more basic side and purely done with hands on demonstrations rather than walk throughs of more complex examples. Alas this session always feels like it needs another half an hour to get through the full sortiment of functionality. The slides and samples cover a wider variety of topics and there are many examples that demonstrate more advanced operations like interacting with WCF REST services, using client templating and building rich client only windowed interfaces. Download Low Level ASP.NET: Handlers and Modules This session was a look at the ASP.NET pipeline and it discusses some of the ASP.NET base architecture and key components from HttpRuntime on up through the various modules and handlers that make up the ASP.NET/IIS pipeline. This session is fun as there are a number of cool examples that demonstrate the power and flexibility of ASP.NET, but some of the examples were external and interfacing with other technologies so they’re not actually included in the downloadable samples. However, there are still a few cool ones in there – there’s an image resizing handler, an image overlay module that stamps images with Sample if loaded from a certain folder, an OpenID authentication module (which failed during the demo due to the crappy internet connection at DevConnections this year :-}), Response filtering using a generic filter stream component, a generic error handler and a few others. The slides cover a lot of the ASP.NET pipeline flow and various HttpRuntime components. Download Electronic Payment Processing in ASP.NET Applications This session covered the business end and integration of electronic credit card processing and PayPal. A good part of this session deals with what’s involved in payment processing, getting signed up and who you have to deal with for your merchant account. We then took a look at integration of credit card processing via some generic components provided with the session that allow processing using a unified class interface with specific implementations for several of the most common gateway providers including Authorize.NET, PayFlowPro, LinkPoint, BluePay etc. We also briefly looked at PayPal Classic implementation which provides a quick and cheap if not quite as professional mechanism for taking payments online. The samples provide the Credit Card processing wrappers for the various gateway providers as well as a PayPal helper class to generate the PayPal redirect urls as well as helper code for dealing with IPN callbacks. Download Hope some of you will find the material useful. Enjoy.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

• Dependency Replication with TFS 2010 Build

  - by Jakob Ehn

  Some time ago, I wrote a post about how to implement dependency replication using TFS 2008 Build. We use this for Library builds, where we set up a build definition for a common library, and have the build check the resulting assemblies back into source control. The folder is then branched to the applications that need to reference the common library. See the above post for more details. Of course, we have reimplemented this feature in TFS 2010 Build, which results in a much nicer experience for the developer who wants to setup a new library build. Here is how it looks: There is a separate build process template for library builds registered in all team projects The following properties are used to configure the library build: Deploy Folder in Source Control is the server path where the assemblies should be checked in DeploymentFiles is a list of files and/or extensions to what files to check in. Default here is *.dll;*.pdb which means that all assemblies and debug symbols will be checked in. We can also type for example CommonLibrary.*;SomeOtherAssembly.dll in order to exclude other assemblies You can also see that we are versioning the assemblies as part of the build. This is important, since the resulting assemblies will be deployed together with the referencing application.   When the build executes, it will see of the matching assemblies exist in source control, if not, it will add the files automatically:   After the build has finished, we can see in the history of the TestDeploy folder that the build service account has in fact checked in a new version: Nice!   The implementation of the library build process template is not very complicated, it is a combination of customization of the build process template and some custom activities. We use the generic TFActivity (http://geekswithblogs.net/jakob/archive/2010/11/03/performing-checkins-in-tfs-2010-build.aspx) to check in and out files, but for the part that checks if a file exists and adds it to source control, it was easier to do this in a custom activity:   public sealed class AddFilesToSourceControl : BaseCodeActivity { // Files to add to source control [RequiredArgument] public InArgument<IEnumerable<string>> Files { get; set; } [RequiredArgument] public InArgument<Workspace> Workspace { get; set; } // If your activity returns a value, derive from CodeActivity<TResult> // and return the value from the Execute method. protected override void Execute(CodeActivityContext context) { foreach (var file in Files.Get(context)) { if (!File.Exists(file)) { throw new ApplicationException("Could not locate " + file); } var ws = this.Workspace.Get(context); string serverPath = ws.TryGetServerItemForLocalItem(file); if( !String.IsNullOrEmpty(serverPath)) { if (!ws.VersionControlServer.ServerItemExists(serverPath, ItemType.File)) { TrackMessage(context, "Adding file " + file); ws.PendAdd(file); } else { TrackMessage(context, "File " + file + " already exists in source control"); } } else { TrackMessage(context, "No server path for " + file); } } } } This build template is a very nice tool that makes it easy to do dependency replication with TFS 2010. Next, I will add funtionality for automatically merging the assemblies (using ILMerge) as part of the build, we do this to keep the number of references to a minimum.

• How To Rip an Audio CD to FLAC with Foobar2000

  - by Mysticgeek

  Foobar2000 is a great audio player that is fully customizable, is light on system resources, and contains a lot of tools and features. Today we show you how to use it to rip an audio CD to FLAC format. Note: For this tutorial we’re going to assume this is the first time you’re ripping a disc with Foobar2000. We’re running it on Windows 7 Ultimate 64-bit. Install Foobar2000 and FLAC First download and install Foobar2000 (link below). The main thing you’ll want to make sure to enable during the install process is Audio CD Support… And the freedb Tagger which are located under Optional Features, then continue through the rest of the install wizard. Next you need to install the latest version of the FLAC codec (link below) following the defaults. Rip Audio CD To rip a CD, place it in your CDROM drive, launch Foobar2000 and click File \ Open Audio CD. Select the appropriate CD drive and click the Rip button. Next you’ll want to lookup the disc information with freedb…or you can manually enter in the track data if it’s a custom disc. Select the proper tag information in the freedb tagger window, then click Update files. The data will be entered in, make sure the radio button next to Go to the Converter Setup dialog is selected, and click the Rip button. In the Converter Setup screen, here you can select the output format, where in our case we’re selecting FLAC. In this window you can choose several other options like the output path, merging the tracks into one or individual files…etc. When you have those settings completed click OK. Next you’ll need to find flac.exe which is located wherever you installed it. On our 64-bit Windows 7 system the default path is C:\Program Files (x86)\FLAC Now wait while your CD is ripped and converted to FLAC. You’ll get a Converter Status Report…after you’ve checked it over you can close out of it. If you set the option to show the output files after conversion you can take a look, make sure all tracks were converted, and play them right away if you want. You can play the tracks in Foobar2000 or any player that supports FLAC. If you want to use WMC or WMP see our article on how to play FLAC files in Windows 7 Media Center or Player. That’s all there is to it! If you’re a fan of Foobar2000 and enjoy your music converted to FLAC format, Foobar2000 does the job quite well. There are a lot of customizations and tools you can use in Foobar2000 that we’ll be taking a look at in future articles.

• Software development stack 2012

  A couple of months ago, I posted on Google+ about my evaluation period for a new software development stack in general. "Analysing existing 'jungle' of multiple applications and tools in various languages for clarification and future design decisions. Great fun and lots of headaches... #DevelopersLife" Surprisingly, there was response... ;-) - And this series of articles is initiated by this post. Thanks Olaf. The past few years... Well, after all my first choice of software development in the past was Microsoft Visual FoxPro 6.0 - 9.0 in combination with Microsoft SQL Server 2000 - 2008 and Crystal Reports 9.x - XI. Honestly, it is my main working environment due to exisiting maintenance and support plans with my customers, but also for new project requests. And... hands on, it is still my first choice for data manipulation and migration options. But the earth is spinning, and as a software craftsman one has to be flexible with the choice of tools. In parallel to my knowledge and expertise in the above mentioned tools, I already started very early to get my hands dirty with the Microsoft .NET Framework. If I remember correctly, I started back in 2002/2003 with the first version ever. But this was more out of curiousity. During the years this kind of development got more serious and demanding, and I focused myself on interop and integrational libraries and applications. Mainly, to expose exisitng features of the .NET Framework to Visual FoxPro - I even had a session about that at the German Developer's Conference in Frankfurt. Observation of recent developments With the recent hype on Javascript and HTML5, especially for Windows 8 and Windows Phone 8 development, I had several 'Deja vu' events... Back in early 2006 (roughly) I had a conversation on the future of Web and Desktop development with my former colleagues Golo Roden and Thomas Wilting about the underestimation of Javascript and its root as a prototype-based, dynamic, full-featured programming language. During this talk with them I took the Mozilla applications, namely Firefox and Thunderbird, as a reference which are mainly based on XML, CSS, Javascript and images - besides the core rendering engine. And that it is very simple to write your own extensions for the Gecko rendering engine. Looking at the Windows Vista Sidebar widgets, just underlines this kind of usage. So, yes the 'Modern UI' of Windows 8 based on HTML5, CSS3 and Javascript didn't come as any surprise to me. Just allow me to ask why did it take so long for Microsoft to come up with this step? A new set of tools Ok, coming from web development in HTML 4, CSS and Javascript prior to Visual FoxPro, I am partly going back to that combination of technologies. What is the other part of the software development stack here at IOS Indian Ocean Software Ltd? Frankly, it is easy and straight forward to describe: Microsoft Visual FoxPro 9.0 SP 2 - still going strong! Visual Studio 2012 (C# on latest .NET Framework) MonoDevelop Telerik DevCraft Suite WPF ASP.NET MVC Windows 8 Kendo UI OpenAccess ORM Reporting JustCode CODE Framework by EPS Software MonoTouch and Mono for Android Subversion and additional tools for the daily routine: Notepad++, JustCode, SQL Compare, DiffMerge, VMware, etc. Following the principles of Clean Code Developer and the Agile Manifesto Actually, nothing special about this combination but rather a solid fundament to work with and create line of business applications for customers.Honestly, I am really interested in your choice of 'weapons' for software development, and hopefully there might be some nice conversations in the comment section. Over the next coming days/weeks I'm going to describe a little bit more in detail about the reasons for my decision. Articles will be added bit by bit here as reference, too. Please bear with me... Regards, JoKi

• Install GIMP 2.7.1 on Lucid Lynx using PPA

  - by Vivek

  GIMP lovers are going to be disappointed to hear that GIMP is going away in the next release of much awaited Ubuntu 10.04. Today we take a look at installing in on Lucid Lynx using PPA. The reason for getting rid of it as cited by the GIMP developers, is that GIMP is too professional a software to be included in regular desktop version of Ubuntu. And it takes up too much of space on the disk. Also, the fact that it’s too complicated for regular users. If you can’t live without it…let’s see how to install GIMP 2.7.1 on Lucid Lynx (Currently in Alpha). The new version of GIMP supports single window mode and we will also see how to enable this feature as well. First we need to add the official GIMP 2.7.1 PPA in the software sources of Ubuntu 10.04, by opening the terminal window and typing the following command: sudo sh -c “echo ‘deb http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu lucid main’ >> /etc/apt/sources.list” Now that we have added the PPA we need to add the GPG key, so type the following in your Terminal window. sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 405A15CB Next up we have to update the software repository… sudo apt-get update All that is left is to install GIMP 2.7.1 by typing in the following… sudo apt-get install gimp Click ‘Y’ (for yes) to install GIMP Once GIMP is installed you can start it by going to Applications > Graphics > GNU Image Manipulation Program. You now have your favorite GIMP on your favorite Ubuntu 10.04. As you can see in the image below, GIMP still comes with default 3 windows, which could clog up your lower panel In Ubuntu 10.04. However, now you can run GIMP in single window mode by going to Windows > Single-Window mode. That’s all! Now you have your GIMP running in single window mode with less of hassle to manage 3 windows. It’s unfortunate that GIMP will not be included, but by following these instructions, you’ll be able to enjoy using it in Ubuntu 10.04.

• Creating an HttpHandler to handle request of your own extension

  - by Jalpesh P. Vadgama

  I have already posted about http handler in details before some time here. Now let’s create an http handler which will handle my custom extension. For that we need to create a http handlers class which will implement Ihttphandler. As we are implementing IHttpHandler we need to implement one method called process request and another one is isReusable property. The process request function will handle all the request of my custom extension. so Here is the code for my http handler class. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; namespace Experiement { public class MyExtensionHandler:IHttpHandler { public MyExtensionHandler() { //Implement intialization here } bool IHttpHandler.IsReusable { get { return true; } } void IHttpHandler.ProcessRequest(HttpContext context) { string excuttablepath = context.Request.AppRelativeCurrentExecutionFilePath; if (excuttablepath.Contains("HelloWorld.dotnetjalps")) { Page page = new HelloWorld(); page.AppRelativeVirtualPath = context.Request.AppRelativeCurrentExecutionFilePath; page.ProcessRequest(context); } } } } Here in above code you can see that in process request function I am getting current executable path and then I am processing that page. Now Lets create a page with extension .dotnetjalps and then we will process this page with above created http handler. so let’s create it. It will create a page like following. Now let’s write some thing in page load Event like following. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace Experiement { public partial class HelloWorld : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Response.Write("Hello World"); } } } Now we have to tell our web server that we want to process request from this .dotnetjalps extension through our custom http handler for that we need to add a tag in httphandler sections of web.config like following. <configuration> <system.web> <compilation debug="true" targetFramework="4.0" /> <httpHandlers> <add verb="*" path="*.dotnetjalps" type="Experiement.MyExtensionHandler,Experiement"/> </httpHandlers> </system.web> </configuration> That’s it now run that page into browser and it will execute like following in browser That’s you.. Isn’t it cool.. Stay tuned for more.. Happy programming.. Technorati Tags: HttpHandler,ASP.NET,Extension

• Do NOT Change "Copy Local” project references to false, unless understand subsequences.

  - by Michael Freidgeim

  To optimize performance of visual studio build I've found multiple recommendations to change CopyLocal property for dependent dlls to false,e.g. From http://stackoverflow.com/questions/690033/best-practices-for-large-solutions-in-visual-studio-2008 CopyLocal? For sure turn this offhttp://stackoverflow.com/questions/280751/what-is-the-best-practice-for-copy-local-and-with-project-referencesAlways set the Copy Local property to false and enforce this via a custom msbuild stephttp://codebetter.com/patricksmacchia/2007/06/20/benefit-from-the-c-and-vb-net-compilers-perf/BenefitBenefitMy advice is to always set ‘Copy Local’ to falseSome time ago we've tried to change the setting to false, and found that it causes problem for deployment of top-level projects.Recently I've followed the suggestion and changed the settings for middle-level projects. It didn't cause immediate issues, but I was warned by Readify Consultant Colin Savage about possible errors during deploymentsI haven't undone the changes immediately and we found a few issues during testing.There are many scenarios, when you need to have Copy Local’ left to True.The concerns are highlighted in some stack overflow answers, but they have small number of votes.Top-level projects:  set copy local = true.First of all, it doesn't work correctly for top-level projects, i.e. executables or web sites.As pointed in the answer http://stackoverflow.com/a/6529461/52277for all the references in the one at the top set copy local = true.Alternatively you have to change output directory as it's described in http://www.simple-talk.com/dotnet/.net-framework/partitioning-your-code-base-through-.net-assemblies-and-visual-studio-projects/If you set ‘ Copy Local = false’, VS will, unless you tell it otherwise, place each assembly alone in its own .\bin\Debugdirectory. Because of this, you will need to configure VS to place assemblies together in the same directory. To do so, for each VS project, go to VS > Project Properties > Build tab > Output path, and set the Ouput path to ..\bin\Debugfor debug configuration, and ..\bin\Release for release configuration.Second-level  dependencies:  set copy local = true.Another example when copylocal =false fails on run-time, is when top level assembly doesn't directly referenced one of indirect dependencies.E..g. Top-level assembly A has reference to assembly B with copylocal =true, but assembly B has reference to assembly C with copylocal =false. Most likely assembly C will be missing on runtime and will cause errors E.g. http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1Copy local is important for deployment scenarios and tools. As a general rule you should use CopyLocal=True and http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1 Unfortunately there are some quirks and CopyLocal won't necessary work as expected for assembly references in secondary assemblies structured as shown below.MainApp.exe MyLibrary.dll ThirdPartyLibrary.dll (if in the GAC CopyLocal won't copy to MainApp bin folder)This makes xcopy deployments difficult . .Reflection called DLLs  dependencies:  set copy local = true.E.g user can see error "ISystem.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."The fix for the issue is recommended in http://stackoverflow.com/a/6200173/52277"I solved this issue by setting the Copy Local attribute of my project's references to true."In general, the problems with investigation of deployment issues may overweight the benefits of reduced build time. Setting the Copy Local to false without considering deployment issues is not a good idea.

• Hello World Pagelet

  - by astemkov

  Introduction The goal of this exercise is to give you a basic feel of how you can use Pagelet Producer to proxy a web page We will proxy a simple static Hello World web page, cut one section out of that page and present it as a pagelet that you can later insert on your own application page or to your portal page such as WebCenter Portal space or WebCenter Interaction community page. Hello World sample app This is the static web page we will work with: Let's assume the following: The Hello World web page is running on server http://appserver.company.com:1234/ The Hello World web page path is: http://appserver.company.com:1234/helloworld/ Initial Pagelet Producer setup Let's assume that the Pagelet Producer server is running on http://pageletserver.company.com:8889/pagelets/ First let's check that Pagelet Producer is up and running. In order to do that we just need to access the following URL: http://pageletserver.company.com:8889/pagelets/ And this is what should be returned: Now you can access Pagelet Producer administration screens using this URL: http://pageletserver.company.com:8889/pagelets/admin This is how the UI looks: Now if you connect to the internet via proxy server, you need to configure proxy in Pagelet Producer settings. In the Navigator pane: Jump To - Settings Click on "Proxy" Enter your proxy server configuration: Creating a resource First thing that you need to do is to create a resource for your web page. This will tell Pagelet Producer that all sub-paths of the web page should be proxied. It also will allow you to setup common rules of how your web page should be proxied and will serve as a container for your pagelets. In the Navigator pane: Jump To - Resources Click on any existing resource (ex. welcome_resource) Click on "Create selected type" toolbar button at the top of the Navigator pane Select "Web" in the "Select Producer Type" dialog box and click "OK" Now after the resource is created let's click on "General" sub-item a specify the following values Name = AppServer Source URL = http://appserver.company.com:1234/ Destination URL = /appserver/ Click on "Save" toolbar button at the top of the Navigator pane After the resource is created our web page becomes accessible by the URL: http://pageletserver.company.com:8889/pagelets/appserver/helloworld/ So in original web page address Source URL is replaced with Pagelet Producer URL (http://pageletserver.company.com:8889/pagelets) + Destination URL Creating a pagelet Now let's create "Hello World" pagelet. Under the resource node activate Pagelets subnode Click on "Create selected type" toolbar button at the top of the Navigator pane Click on "General" sub-node of newly created pagelet and specify the following values Name = Hello_World Library = MyLib Library is used for logical grouping. The portals use the "Library" value to group pagelets in their respective UI's. For example, when adding pagelets to a WebCenter Portal space you would see the individual pagelets listed under the "Library" name. URL Suffix = helloworld/index.html this is where the Hello World page html is served from Click on "Save" toolbar button at the top of the Navigator pane The Library name can be anything you want, it doesn't have to match the resource name at all. It is used as a logical grouping of pagelets, and you can include pagelets from multiple resources into the same library or create a new library for each pagelet. After you save the pagelet you can access it here: http://pageletserver.company.com:8889/pagelets/inject/v2/pagelet/MyLib/Hello_World which is : http://pageletserver.company.com:8889/pagelets/inject/v2/pagelet/ + [Library] + [Name] Or to test the injection of a pagelet into iframe you can click on the pagelets "Documentation" sub-node and use "Access Pagelet using REST" URL: This is what we will see: Clipping The pagelet that we just created covers the whole web page, but we want just the "Hello World" segment of it. So let's clip it. Under the Hello_World pagelet node activate Clipper sub-node Click on "Create selected type" toolbar button at the top of the Navigator pane Specify a Name for newly created clipper. For example: "c1" Click on "Content" sub-node of the clipper Click on "Launch Clipper" button New browser window will open By moving a mouse pointer over the web page select the area you want to clip: Click left mouse button - the browser window will disappear and you will see that Clipping Path was automatically generated Now let's save and access the link from the "Documentation" page again Here's our pagelet nicely clipped and ready for being used on your Web Center Space

• Extended Logging with Caller Info Attributes

  - by João Angelo

  .NET 4.5 caller info attributes may be one of those features that do not get much airtime, but nonetheless are a great addition to the framework. These attributes will allow you to programmatically access information about the caller of a given method, more specifically, the code file full path, the member name of the caller and the line number at which the method was called. They are implemented by taking advantage of C# 4.0 optional parameters and are a compile time feature so as an added bonus the returned member name is not affected by obfuscation. The main usage scenario will be for tracing and debugging routines as will see right now. In this sample code I’ll be using NLog, but the example is also applicable to other logging frameworks like log4net. First an helper class, without any dependencies and that can be used anywhere to obtain caller information: using System; using System.IO; using System.Runtime.CompilerServices; public sealed class CallerInfo { private CallerInfo(string filePath, string memberName, int lineNumber) { this.FilePath = filePath; this.MemberName = memberName; this.LineNumber = lineNumber; } public static CallerInfo Create( [CallerFilePath] string filePath = "", [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0) { return new CallerInfo(filePath, memberName, lineNumber); } public string FilePath { get; private set; } public string FileName { get { return this.fileName ?? (this.fileName = Path.GetFileName(this.FilePath)); } } public string MemberName { get; private set; } public int LineNumber { get; private set; } public override string ToString() { return string.Concat(this.FilePath, "|", this.MemberName, "|", this.LineNumber); } private string fileName; } Then an extension class specific for NLog Logger: using System; using System.Runtime.CompilerServices; using NLog; public static class LoggerExtensions { public static void TraceMemberEntry( this Logger logger, [CallerFilePath] string filePath = "", [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0) { LogMemberEntry(logger, LogLevel.Trace, filePath, memberName, lineNumber); } public static void TraceMemberExit( this Logger logger, [CallerFilePath] string filePath = "", [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0) { LogMemberExit(logger, LogLevel.Trace, filePath, memberName, lineNumber); } public static void DebugMemberEntry( this Logger logger, [CallerFilePath] string filePath = "", [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0) { LogMemberEntry(logger, LogLevel.Debug, filePath, memberName, lineNumber); } public static void DebugMemberExit( this Logger logger, [CallerFilePath] string filePath = "", [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0) { LogMemberExit(logger, LogLevel.Debug, filePath, memberName, lineNumber); } public static void LogMemberEntry( this Logger logger, LogLevel logLevel, [CallerFilePath] string filePath = "", [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0) { const string MsgFormat = "Entering member {1} at line {2}"; InternalLog(logger, logLevel, MsgFormat, filePath, memberName, lineNumber); } public static void LogMemberExit( this Logger logger, LogLevel logLevel, [CallerFilePath] string filePath = "", [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0) { const string MsgFormat = "Exiting member {1} at line {2}"; InternalLog(logger, logLevel, MsgFormat, filePath, memberName, lineNumber); } private static void InternalLog( Logger logger, LogLevel logLevel, string format, string filePath, string memberName, int lineNumber) { if (logger == null) throw new ArgumentNullException("logger"); if (logLevel == null) throw new ArgumentNullException("logLevel"); logger.Log(logLevel, format, filePath, memberName, lineNumber); } } Finally an usage example: using NLog; internal static class Program { private static readonly Logger Logger = LogManager.GetCurrentClassLogger(); private static void Main(string[] args) { Logger.TraceMemberEntry(); // Compile time feature // Next three lines output the same except for line number Logger.Trace(CallerInfo.Create().ToString()); Logger.Trace(() => CallerInfo.Create().ToString()); Logger.Trace(delegate() { return CallerInfo.Create().ToString(); }); Logger.TraceMemberExit(); } } NOTE: Code for helper class and Logger extension also available here.

• WCF REST Service Activation Errors when AspNetCompatibility is enabled

  - by Rick Strahl

  I’m struggling with an interesting problem with WCF REST since last night and I haven’t been able to track this down. I have a WCF REST Service set up and when accessing the .SVC file it crashes with a version mismatch for System.ServiceModel: Server Error in '/AspNetClient' Application. Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.TypeLoadException: Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [TypeLoadException: Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.] System.RuntimeTypeHandle.GetTypeByName(String name, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMarkHandle stackMark, Boolean loadTypeFromPartialName, ObjectHandleOnStack type) +0 System.RuntimeTypeHandle.GetTypeByName(String name, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMark& stackMark, Boolean loadTypeFromPartialName) +95 System.RuntimeType.GetType(String typeName, Boolean throwOnError, Boolean ignoreCase, Boolean reflectionOnly, StackCrawlMark& stackMark) +54 System.Type.GetType(String typeName, Boolean throwOnError, Boolean ignoreCase) +65 System.Web.Compilation.BuildManager.GetType(String typeName, Boolean throwOnError, Boolean ignoreCase) +69 System.Web.Configuration.HandlerFactoryCache.GetTypeWithAssert(String type) +38 System.Web.Configuration.HandlerFactoryCache.GetHandlerType(String type) +13 System.Web.Configuration.HandlerFactoryCache..ctor(String type) +19 System.Web.HttpApplication.GetFactory(String type) +81 System.Web.MaterializeHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +223 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +184 Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1 What’s really odd about this is that it crashes only if it runs inside of IIS (it works fine in Cassini) and only if ASP.NET Compatibility is enabled in web.config:<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> Arrrgh!!!!! After some experimenting and some help from Glenn Block and his team mates I was able to track down the problem in ApplicationHost.config. Specifically the problem was that there were multiple *.svc mappings in the ApplicationHost.Config file and the older 2.0 runtime specific versions weren’t marked for the proper runtime. Because these handlers show up at the top of the list they execute first resulting in assembly load errors for the wrong version assembly. To fix this problem I ended up making a couple changes in applicationhost.config. On the machine level root’s Handler mappings I had an entry that looked like this:<add name="svc-Integrated" path="*.svc" verb="*" type="System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="integratedMode" /> and it needs to be changed to this:<add name="svc-Integrated" path="*.svc" verb="*" type="System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="integratedMode,runtimeVersionv2.0" />Notice the explicit runtime version assignment in the preCondition attribute which is key to keep ASP.NET 4.0 from executing that handler. The key here is that the runtime version needs to be set explicitly so that the various *.svc handlers don’t fire only in the order defined which in case of a .NET 4.0 app with the original setting would result in an incompatible version of System.ComponentModel to load.What was really hard to track this down is that even when looking in the debugger when launching the Web app, the AppDomain assembly loads showed System.ServiceModel V4.0 starting up just fine. Apparently the ASP.NET runtime load occurs at a different point and that’s when things break.So how did this break? According to the Microsoft folks it’s some older tools that got installed that change the default service handlers. There’s a blog entry that points at this problem with more detail:http://blogs.iis.net/webtopics/archive/2010/04/28/system-typeloadexception-for-system-servicemodel-activation-httpmodule-in-asp-net-4.aspxNote that I tried running aspnet_regiis and that did not fix the problem for me. I had to manually change the entries in applicationhost.config.   © Rick Strahl, West Wind Technologies, 2005-2011Posted in AJAX   ASP.NET  WCF

• OWB 11gR2 - Find and Search Metadata in Designer

  - by David Allan

  Here are some tools and techniques for finding objects, specifically in the design repository. There are ways of navigating and collating objects that are useful for day to day development and build-time usage - this includes features out of the box and utilities constructed on top. There are a variety of techniques to navigate and find objects in the repository, the first 3 are out of the box, the 4th is an expert utility. Navigating by the tree, grouping by project and module - ok if you are aware of the exact module/folder that objects reside in. The structure panel is a useful way of finding parts of an object, especially when large rather than using the canvas. In large scale projects it helps to have accelerators (either find or collections below). Advanced find to search by name - 11gR2 included a find capability specifically for large scale projects. There were improvements in both the tree search and the object editors (including highlighting in mapping for example). So you can now do regular expression based search and quickly navigate to objects within a repository. Collections - logically organize your objects into virtual folders by shortcutting the actual objects. This is useful for a range of things since all the OWB services operate on collections too (export/import, validation, deployment). See the post here for new collection functionality in 11gR2. Reports for searching by type, updated on, updated by etc. Useful for activities such as periodic incremental actions (deploy all mappings changed in the past week). The report style view is useful since I can quickly see who changed what and when. You can see all the audit details for objects within each objects property inspector, but its useful to just get all objects changed today or example, all objects changed since my last build etc. This utility combines both UI extensions via experts and the public views on the repository. In the figure to the right you see the contextual option 'Object Search' which invokes the utility, you can see I have quite a number of modules within my project. Figure out all the potential objects which have been changed is not simple. The utility is an expert which provides this kind of search capability. The utility provides a report of the objects in the design repository which satisfy some filter criteria. The type of criteria includes; objects updated in the last n days optionally filter the objects updated by user filter the user by project and by type (table/mappings etc.) The search dialog appears with these options, you can multi-select the object types, so for example you can select TABLE and MAPPING. Its also possible to search across projects if need be. If you have multiple users using the repository you can define the OWB user name in the 'Updated by' property to restrict the report to just that user also. Finally there is a search name that will be used for some of the options such as building a collection - this name is used for the collection to be built. In the example I have done, I've just searched my project for all process flows and mappings that users have updated in the last 7 days. The results of the query are returned in a table containing the object names, types, full path and audit details. The columns are sort-able, you can sort the results by name, type, path etc. One of the cool things here, is that you can then perform operations on these objects - such as edit them, export single selection or entire results to MDL, create a collection from the results (now you have a saved set of references in the repository, you could do deploy/export etc.), create a deployment script from the results...or even add in your own ideas! You see from this that you can do bulk operations on sets of objects based on search results. So for example selecting the 'Build Collection' option creates a collection with all of the objects from my search, you can subsequently deploy/generate/maintain this collection of objects. Under the hood of the expert if just basic OMB commands from the product and the use of the public views on the design repository. You can see how easy it is to build up macro-like capabilities that will help you do day-to-day as well as build like tasks on sets of objects.

• SQL SERVER – DQS Error – Cannot connect to server – A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessions” – SetDataQualitySessionPhaseTwo

  - by pinaldave

  Earlier I wrote a blog post about how to install DQS in SQL Server 2012. Today I decided to write a second part of this series where I explain how to use DQS, however, as soon as I started the DQS client, I encountered an error that will not let me pass through and connect with DQS client. It was a bit strange to me as everything was functioning very well when I left it last time.  The error was very big but here are the first few words of it. Cannot connect to server. A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessions”: System.Data.SqlClient.SqlException (0×80131904): A .NET Framework error occurred during execution of user-defined routine or aggregate “SetDataQualitySessionPhaseTwo”: The error continues – here is the quick screenshot of the error. As my initial attempts could not fix the error I decided to search online and I finally received a wonderful solution from Microsoft Site. The error has happened due to latest update I had installed on .NET Framework 4. There was a  mismatch between the Module Version IDs (MVIDs) of the SQL Common Language Runtime (SQLCLR) assemblies in the SQL Server 2012 database and the Global Assembly Cache (GAC). This mismatch was to be resolved for the DQS to work properly. The workaround is specified here in detail. Scroll to subtopic 4.23 Some .NET Framework 4 Updates Might Cause DQS to Fail. The script was very much straight forward. Here are the few things to not to miss while applying workaround. Make sure DQS client is properly closed The NETAssemblies is based on your OS. NETAssemblies for 64 bit machine – which is my machine is “c:\windows\Microsoft.NET\Framework64\v4.0.30319″. If you have Winodws installed on any other drive other than c:\windows do not forget to change that in the above path. Additionally if you have 32 bit version installed on c:\windows you should use path as ”c:\windows\Microsoft.NET\Framework\v4.0.30319″ Make sure that you execute the script specified in 4.23 sections in this article in the database DQS_MAIN. Do not run this in the master database as this will not fix your error. Do not forget to restart your SQL Services once above script has been executed. Once you open the client it will work this time. Here is the script which I have bit modified from original script. I strongly suggest that you use original script mentioned 4.23 sections. However, this one is customized my own machine. /* Original source: http://bit.ly/PXX4NE (Technet) Modifications: -- Added Database context -- Added environment variable @NETAssemblies -- Main script modified to use @NETAssemblies */ USE DQS_MAIN GO BEGIN -- Set your environment variable -- assumption - Windows is installed in c:\windows folder DECLARE @NETAssemblies NVARCHAR(200) -- For 64 bit uncomment following line SET @NETAssemblies = 'c:\windows\Microsoft.NET\Framework64\v4.0.30319\' -- For 32 bit uncomment following line -- SET @NETAssemblies = 'c:\windows\Microsoft.NET\Framework\v4.0.30319\' DECLARE @AssemblyName NVARCHAR(200), @RefreshCmd NVARCHAR(200), @ErrMsg NVARCHAR(200) DECLARE ASSEMBLY_CURSOR CURSOR FOR SELECT name AS NAME FROM sys.assemblies WHERE name NOT LIKE '%ssdqs%' AND name NOT LIKE '%microsoft.sqlserver.types%' AND name NOT LIKE '%practices%' AND name NOT LIKE '%office%' AND name NOT LIKE '%stdole%' AND name NOT LIKE '%Microsoft.Vbe.Interop%' OPEN ASSEMBLY_CURSOR FETCH NEXT FROM ASSEMBLY_CURSOR INTO @AssemblyName WHILE @@FETCH_STATUS = 0 BEGIN BEGIN TRY SET @RefreshCmd = 'ALTER ASSEMBLY [' + @AssemblyName + '] FROM ''' + @NETAssemblies + @AssemblyName + '.dll' + ''' WITH PERMISSION_SET = UNSAFE' EXEC sp_executesql @RefreshCmd PRINT 'Successfully upgraded assembly ''' + @AssemblyName + '''' END TRY BEGIN CATCH IF ERROR_NUMBER() != 6285 BEGIN SET @ErrMsg = ERROR_MESSAGE() PRINT 'Failed refreshing assembly ' + @AssemblyName + '.

• SQL SERVER – Understanding XML – Contest Win Joes 2 Pros Combo (USD 198) – Day 5 of 5

  - by pinaldave

  August 2011 we ran a contest where every day we give away one book for an entire month. The contest had extreme success. Lots of people participated and lots of give away. I have received lots of questions if we are doing something similar this month. Absolutely, instead of running a contest a month long we are doing something more interesting. We are giving away USD 198 worth gift every day for this week. We are giving away Joes 2 Pros 5 Volumes (BOOK) SQL 2008 Development Certification Training Kit every day. One copy in India and One in USA. Total 2 of the giveaway (worth USD 198). All the gifts are sponsored from the Koenig Training Solution and Joes 2 Pros. The books are available here Amazon | Flipkart | Indiaplaza How to Win: Read the Question Read the Hints Answer the Quiz in Contact Form in following format Question Answer Name of the country (The contest is open for USA and India residents only) 2 Winners will be randomly selected announced on August 20th. Question of the Day: Is following XML a well formed XML Document? <?xml version=”1.0″?> <address> <firstname>Pinal</firstname> <lastname>Dave</lastname> <title>Founder</title> <company>SQLAuthority.com</company> </address> a) Yes b) No c) I do not know Query Hints: BIG HINT POST A common observation by people seeing an XML file for the first time is that it looks like just a bunch of data inside a text file. XML files are text-based documents, which makes them easy to read.  All of the data is literally spelled out in the document and relies on a just a few characters (<, >, =) to convey relationships and structure of the data.  XML files can be used by any commonly available text editor, like Notepad. Much like a book’s Table of Contents, your first glance at well-formed XML will tell you the subject matter of the data and its general structure. Hints appearing within the data help you to quickly identify the main theme (similar to book’s subject), its headers (similar to chapter titles or sections of a book), data elements (similar to a book’s characters or chief topics), and so forth. We’ll learn to recognize and use the structural “hints,” which are XML’s markup components (e.g., XML tags, root elements). The XML Raw and Auto modes are great for displaying data as all attributes or all elements – but not both at once. If you want your XML stream to have some of its data shown in attributes and some shown as elements, then you can use the XML Path mode. If you are using an XML Path stream, then by default all values will be shown as elements. However, it is possible to pick one or more elements to be shown with an attribute(s) as well. Additional Hints: I have previously discussed various concepts from SQL Server Joes 2 Pros Volume 5. SQL Joes 2 Pros Development Series – OpenXML Options SQL Joes 2 Pros Development Series – Preparing XML in Memory SQL Joes 2 Pros Development Series – Shredding XML SQL Joes 2 Pros Development Series – Using Root With Auto XML Mode SQL Joes 2 Pros Development Series – Using Root With Auto XML Mode SQL Joes 2 Pros Development Series – What is XML? SQL Joes 2 Pros Development Series – What is XML? – 2 Next Step: Answer the Quiz in Contact Form in following format Question - Answer Name of the country (The contest is open for USA and India) Bonus Winner Leave a comment with your favorite article from the “additional hints” section and you may be eligible for surprise gift.

• Customizing Spaces UI

  - by vijaykumar.yenne

  In most common scenarios we stumble up on use cases to customize the Web center spaces UI. Is the Spaces UI customizable? What is the extent to which we can customize? How do i customize it? These are some questions that developers/architects normally come across. Well to clear the air, OOTB spaces comes with some default "site templates" and it also gives a flexibility to create custom site templates suiting the organization needs. The site templates concept has been introduced in the latest PS1 release of webcenter and to customize/create the the new site template, we have to leverage the Extend Spaces Project available on OTN. You could download the the project from here. Also there is white paper available on what all can be customized/extended from spaces perspective listed here . There is a specific details outlined on how to create custom site template in the Customizing Site Template white paper. One of the things the white paper high lights is "While you can create new site templates and modify the sample site templates but you cannot modify either of the out-of-the-box site templates ie the default and maximized. So if my need is to either increase the size of header to fit in a bigger logo or introduce couple of extra links on the default/maximized lay out how do i achieve this? All you need to do is customize the OOTB shell (shell-config.xml). 1. Copy the shell config's available in the Source Files Directory of the extended spaces unzipped directory into the CustomSite Template Project ExtendWebCenterSpaces\CustomSiteTemplate\custom\oracle\webcenter\webcenterapp\metadata\shell 2. Modify the appropriate shell 3. Deploy the CustomSite Template as ADF Jar 4. ensure you have the profile dependency on the aboproject int he custom webcenter spaces project 5. Deploy the Spaces Extension on the Webcenter Spaces Instance. (Details in the first white paper). You should see the changes immediately. eg: In the default shell, i have changed the height from 30 to 60 to increase the header size height="60" This is what i get to see : If you have worked on the R1 release time frame, where you created a custom shell/chrome, how do we make them compatible and make it available in the Spaces PS1 instance? All you need to do is the following: 1. Copy the custom shell in to the shell directory of the custom site template project 2. Register the shell with WCSiteTemplates.xml available in the same project. Eg : Yo can add the below entry pagePath="/oracle/webcenter/webcenterapp/view/templates/MyShellTemplate.jspx" pageDefPath="/oracle/webcenter/webcenterapp/bindings/pageDefs/oracle_webcenter_webcenterapp_view_templates_WebCenterAppShellTemplatePageDef.xml" displayName="myShell" chromeLevel="myShell"/ Note : pagePath - Absolute path of the template JSPX file. This path must be unique. So you might have to do the following to get your custom chrome working absolutely fine with no problems at all: 1. Create a jspx page, say /custom/mysite/SiteTemplate.jspx 2. Include the the default jspx in the new site template like following SiteTemplate.jspx ------------------ 3. Add the newly created site template in the WCSiteTemplate.xml file like following - pagePath="/custom/mysite/SiteTemplate.jspx" pageDefPath="/oracle/webcenter/webcenterapp/bindings/pageDefs/oracle_webcenter_webcenterapp_view_templates_WebCenterAppShellTemplatePageDef.xml" displayName="myShell" chromeLevel="myShell"/

• Use Any Folder For Your Ubuntu Desktop (Even a Dropbox Folder)

  - by Trevor Bekolay

  By default, Ubuntu creates a folder called Desktop in your home directory that gets displayed on your desktop. What if you want to use something else, like your Dropbox folder? Here we look at how to use any folder for your desktop. Not only can you change your desktop folder, you can change the location of any other folder Ubuntu creates for you in your home folder, like Documents or Music – and this works in any Linux distribution using the Gnome desktop manager. In this example, we’re going to change desktop to show our Dropbox folder. Open your home folder in a File Browser by clicking on Places > Home Folder. In the Home Folder, open the .config folder. By default, .config is hidden, so you may have to show hidden folders (temporarily) by clicking on View > Show Hidden Files. Then open the .config folder by double-clicking on it. Now open the user-dirs.dirs file… If double-clicking on it does not open it in a text editor, right-click on it and choose Open with Other Application… and find a text editor like Gedit. Change the entry associated with XDG_DESKTOP_DIR to the folder you want to be shown as your desktop. In our case, this is $HOME/Dropbox. Note: The “~” shortcut for the home directory won’t work in this file (use $HOME for that), but an absolute path (i.e. a path starting with “/”) will work. Feel free to change the locations of the other folders as well. Save and close user-dirs.dirs. At this point you can either log off and then log back on to get your desktop back, or open a terminal window Applications > Accessories > Terminal and enter: killall nautilus Nautilus (the file manager in Gnome) will restart itself and display your newly chosen folder as the desktop! This is a cool trick to use any folder for your Ubuntu desktop. What did you use as your desktop folder? Let us know in the comments!

• How to create managed properties at site collection level in SharePoint2013

  - by ybbest

  In SharePoint2013, you can create managed properties at site collection. Today, I’d like to show you how to do so through PowerShell. 1. Define your managed properties and crawled properties and managed property Type in an external csv file. PowerShell script will read this file and create the managed and the mapping. 2. As you can see I also defined variant Type, this is because you need the variant type to create the crawled property. In order to have the crawled properties, you need to do a full crawl and also make sure you have data populated for your custom column. However, if you do not want to a full crawl to create those crawled properties, you can create them yourself by using the PowerShell; however you need to make sure the crawled properties you created have the same name if created by a full crawl. Managed properties type: Text = 1 Integer = 2 Decimal = 3 DateTime = 4 YesNo = 5 Binary = 6 Variant Type: Text = 31 Integer = 20 Decimal = 5 DateTime = 64 YesNo = 11 3. You can use the following script to create your managed properties at site collection level, the differences for creating managed property at site collection level is to pass in the site collection id. param( [string] $siteUrl="http://SP2013/", [string] $searchAppName = "Search Service Application", $ManagedPropertiesList=(IMPORT-CSV ".\ManagedProperties.csv") ) Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue $searchapp = $null function AppendLog { param ([string] $msg, [string] $msgColor) $currentDateTime = Get-Date $msg = $msg + " --- " + $currentDateTime if (!($logOnly -eq $True)) { # write to console Write-Host -f $msgColor $msg } # write to log file Add-Content $logFilePath $msg } $scriptPath = Split-Path $myInvocation.MyCommand.Path $logFilePath = $scriptPath + "\CreateManagedProperties_Log.txt" function CreateRefiner {param ([string] $crawledName, [string] $managedPropertyName, [Int32] $variantType, [Int32] $managedPropertyType,[System.GUID] $siteID) $cat = Get-SPEnterpriseSearchMetadataCategory –Identity SharePoint -SearchApplication $searchapp $crawledproperty = Get-SPEnterpriseSearchMetadataCrawledProperty -Name $crawledName -SearchApplication $searchapp -SiteCollection $siteID if($crawledproperty -eq $null) { Write-Host AppendLog "Creating Crawled Property for $managedPropertyName" Yellow $crawledproperty = New-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -VariantType $variantType -SiteCollection $siteID -Category $cat -PropSet "00130329-0000-0130-c000-000000131346" -Name $crawledName -IsNameEnum $false } $managedproperty = Get-SPEnterpriseSearchMetadataManagedProperty -Identity $managedPropertyName -SearchApplication $searchapp -SiteCollection $siteID -ErrorAction SilentlyContinue if($managedproperty -eq $null) { Write-Host AppendLog "Creating Managed Property for $managedPropertyName" Yellow $managedproperty = New-SPEnterpriseSearchMetadataManagedProperty -Name $managedPropertyName -Type $managedPropertyType -SiteCollection $siteID -SearchApplication $searchapp -Queryable:$true -Retrievable:$true -FullTextQueriable:$true -RemoveDuplicates:$false -RespectPriority:$true -IncludeInMd5:$true } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } if($mappedProperty -eq $null) { Write-Host AppendLog "Creating Crawled -> Managed Property mapping for $managedPropertyName" Yellow New-SPEnterpriseSearchMetadataMapping -CrawledProperty $crawledproperty -ManagedProperty $managedproperty -SearchApplication $searchapp -SiteCollection $siteID } $mappedProperty = $crawledproperty.GetMappedManagedProperties() | ?{$_.Name -eq $managedProperty.Name } #Get-FASTSearchMetadataCrawledPropertyMapping -ManagedProperty $managedproperty } $searchapp = Get-SPEnterpriseSearchServiceApplication $searchAppName $site= Get-SPSite $siteUrl $siteId=$site.id Write-Host "Start creating Managed properties" $i = 1 FOREACH ($property in $ManagedPropertiesList) { $propertyName=$property.managedPropertyName $crawledName=$property.crawledName $managedPropertyType=$property.managedPropertyType $variantType=$property.variantType Write-Host $managedPropertyType Write-Host "Processing managed property $propertyName $($i)..." $i++ CreateRefiner $crawledName $propertyName $variantType $managedPropertyType $siteId Write-Host "Managed property created " $propertyName } Key Concepts Crawled Properties: Crawled properties are discovered by the search index service component when crawling content. Managed Properties: Properties that are part of the Search user experience, which means they are available for search results, advanced search, and so on, are managed properties. Mapping Crawled Properties to Managed Properties: To make a crawled property available for the Search experience—to make it available for Search queries and display it in Advanced Search and search results—you must map it to a managed property.

• RPi and Java Embedded GPIO: Writing Java code to blink LED

  - by hinkmond

  So, you've followed the previous steps to install Java Embedded on your Raspberry Pi ?, you went to Fry's and picked up some jumper wires, LEDs, and resistors ?, you hooked up the wires, LED, and resistor the the correct pins ?, and now you want to start programming in Java on your RPi? Yes? ???????! OK, then... Here we go. You can use the following source code to blink your first LED on your RPi using Java. In the code you can see that I'm not using any complicated gpio libraries like wiringpi or pi4j, and I'm not doing any low-level pin manipulation like you can in C. And, I'm not using python (hell no!). This is Java programming, so we keep it simple (and more readable) than those other programming languages. See: Write Java code to do this In the Java code, I'm opening up the RPi Debian Wheezy well-defined file handles to control the GPIO ports. First I'm resetting everything using the unexport/export file handles. (On the RPi, if you open the well-defined file handles and write certain ASCII text to them, you can drive your GPIO to perform certain operations. See this GPIO reference). Next, I write a "1" then "0" to the value file handle of the GPIO0 port (see the previous pinout diagram). That makes the LED blink. Then, I loop to infinity. Easy, huh? import java.io.* /* * Java Embedded Raspberry Pi GPIO app */ package jerpigpio; import java.io.FileWriter; /** * * @author hinkmond */ public class JerpiGPIO { static final String GPIO_OUT = "out"; static final String GPIO_ON = "1"; static final String GPIO_OFF = "0"; static final String GPIO_CH00="0"; /** * @param args the command line arguments */ public static void main(String[] args) { FileWriter commandFile; try { /*** Init GPIO port for output ***/ // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); // Reset the port unexportFile.write(GPIO_CH00); unexportFile.flush(); // Set the port for use exportFile.write(GPIO_CH00); exportFile.flush(); // Open file handle to port input/output control FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio"+GPIO_CH00+"/direction"); // Set port for output directionFile.write(GPIO_OUT); directionFile.flush(); /*--- Send commands to GPIO port ---*/ // Opne file handle to issue commands to GPIO port commandFile = new FileWriter("/sys/class/gpio/gpio"+GPIO_CH00+"/value"); // Loop forever while (true) { // Set GPIO port ON commandFile.write(GPIO_ON); commandFile.flush(); // Wait for a while java.lang.Thread.sleep(200); // Set GPIO port OFF commandFile.write(GPIO_OFF); commandFile.flush(); // Wait for a while java.lang.Thread.sleep(200); } } catch (Exception exception) { exception.printStackTrace(); } } } Hinkmond
