Now Available – Windows Azure SDK 1.6

- by Shaun

Microsoft has just announced the Windows Azure SDK 1.6 and the Windows Azure Tools for Visual Studio 1.6. Now people can download the latest product through the WebPI. After you downloaded and installed the SDK you will find that The SDK 1.6 can be stayed side by side with the SDK 1.5, which means you can still using the 1.5 assemblies. But the Visual Studio Tools would be upgraded to 1.6. Different from the previous SDK, in this version it includes 4 components: Windows Azure Authoring Tools, Windows Azure Emulators, Windows Azure Libraries for .NET 1.6 and the Windows Azure Tools for Microsoft Visual Studio 2010. There are some significant upgrades in this version, which are Publishing Enhancement: More easily connect to the Windows Azure when publish your application by retrieving a publish setting file. It will let you configure some settings of the deployment, without getting back to the developer portal. Multi-profiles: The publish settings, cloud configuration files, etc. will be stored in one or more MSBuild files. It will be much easier to switch the settings between vary build environments. MSBuild Command-line Build Support. In-Place Upgrade Support. Publishing Enhancement So let’s have a look about the new features of the publishing. Just create a new Windows Azure project in Visual Studio 2010 with a MVC 3 Web Role, and right-click the Windows Azure project node in the solution explorer, then select Publish, we will find the new publish dialog. In this version the first thing we need to do is to connect to our Windows Azure subscription. Click the “Sign in to download credentials” link, we will be navigated to the login page to provide the Live ID. The Windows Azure Tool will generate a certificate file and uploaded to the subscriptions those belong to us. Then we will download a PUBLISHSETTINGS file, which contains the credentials and subscriptions information. The Visual Studio Tool will generate a certificate and deployed to the subscriptions you have as the Management Certificate. The VS Tool will use this certificate to connect to the subscription in the next step. In the next step, I would back to the Visual Studio (the publish dialog should be stilling opened) and click the Import button, select the PUBLISHSETTINGS file I had just downloaded. Then all my subscriptions will be shown in the dropdown list. Select a subscription that I want the application to be published and press the Next button, then we can select the hosted service, environment, build configuration and service configuration shown in the dialog. In this version we can create a new hosted service directly here rather than go back to the developer portal. Just select the <Create New …> item in the hosted service. What we need to do is to provide the hosted service name and the location. Once clicked the OK, after several seconds the hosted service will be established. If we went to the developer portal we will find the new hosted service in my subscription. a) Currently we cannot select the Affinity Group when create a new hosted service through the Visual Studio Publish dialog. b) Although we can specify the hosted service name and DNS prefixing through the developer portal, we cannot do so from the VS Tool, which means the DNS prefixing would be the same as what we specified for the hosted service name. For example, we specified our hosted service name as “Sdk16Demo”, so the public URL would be http://sdk16demo.cloudapp.net/. After created a new hosted service we can select the cloud environment (production or staging), the build configuration (release or debug), and the service configuration (cloud or local). And we can set the Remote Desktop by check the related checkbox as well. One thing should be note is that, in this version when we set the Remote Desktop settings we don’t need to specify a certificate by default. This is because the Visual Studio will generate a new certificate for us by default. But we can still specify an existing certificate for RDC, by clicking the “More Options” button. Visual Studio Tool will create another certificate for the Remote Desktop connection. It will NOT use the certificate that managing the subscription. We also can select the “Advanced Settings” page to specify the deployment label, storage account, IntelliTrace and .NET profiling information, etc.. Press Next button, the dialog will display all settings I had just specified and it will save them as a new profile. The last step is to click the Publish button. Since we enabled the Remote Desktop feature, the first step of publishing was uploading the certificate. And then it will verify the storage account we specified and upload the package, then finally created the website in Windows Azure. Multi-Profiles After published, if we back to the Visual Studio we can find a AZUREPUBXML file under the Profiles folder in the Azure project. It includes all settings we specified before. If we publish this project again, we can just use the current settings (hosted service, environment, RDC, etc.) from this profile without input them again. And this is very useful when we have more than one deployment settings. For example it would be able to have one AZUREPUBXML profile for deploying to testing environment (debug building, less roles with RDC and IntelliTrace) and one for production (release building, more roles but without IntelliTrace). In-Place Upgrade Support Let’s change some codes in the MVC pages and click the Publish menu from the azure project node. No need to specify any settings, here we can use the pervious settings by loading the azure profile file (AZUREPUBXML). After clicked the Publish button the VS Tool brought a dialog to us to indicate that there’s a deployment available in the hosted service environment, and prompt to REPLACE it or not. Notice that in this version, the dialog tool said “replace” rather than “delete”, which means by default the VS Tool will use In-Place Upgrade when we deploy to a hosted service that has a deployment already exist. After click Yes the VS Tool will upload the package and perform the In-Place Upgrade. If we back to the developer portal we can find that the status of the hosted service was turned to “Updating…”. But in the previous SDK, it will try to delete the whole deployment and publish a new one. Summary When the Microsoft announced the features that allows the changing VM size via In-Place Upgrade, they also mentioned that in the next few versions the user experience of publishing the azure application would be improved. The target was trying to accomplish the whole publish experience in Visual Studio, which means no need to touch developer portal any more. In the SDK 1.6 we can see from the new publish dialog, as a developer we can do the whole process, includes creating hosted service, specifying the environment, configuration, remote desktop, etc. values without going back the the developer portal.

Robotic Arm – Hardware

- by Szymon Kobalczyk

This is first in series of articles about project I've been building in my spare time since last Summer. Actually it all began when I was researching a topic of modeling human motion kinematics in order to create gesture recognition library for Kinect. This ties heavily into motion theory of robotic manipulators so I also glanced at some designs of robotic arms. Somehow I stumbled upon this cool looking open source robotic arm: It was featured on Thingiverse and published by user jjshortcut (Jan-Jaap). Since for some time I got hooked on toying with microcontrollers, robots and other electronics, I decided to give it a try and build it myself. In this post I will describe the hardware build of the arm and in later posts I will be writing about the software to control it. Another reason to build the arm myself was the cost factor. Even small commercial robotic arms are quite expensive – products from Lynxmotion and Dagu look great but both cost around USD $300 (actually there is one cheap arm available but it looks more like a toy to me). In comparison this design is quite cheap. It uses seven hobby grade servos and even the cheapest ones should work fine. The structure is build from a set of laser cut parts connected with few metal spacers (15mm and 47mm) and lots of M3 screws. Other than that you’d only need a microcontroller board to drive the servos. So in total it comes a lot cheaper to build it yourself than buy an of the shelf robotic arm. Oh, and if you don’t like this one there are few more robotic arm projects at Thingiverse (including one by oomlout). Laser cut parts Some time ago I’ve build another robot using laser cut parts so I knew the process already. You can grab the design files in both DXF and EPS format from Thingiverse, and there are also 3D models of each part in STL. Actually the design is split into a second project for the mini servo gripper (there is also a standard servo version available but it won’t fit this arm). I wanted to make some small adjustments, layout, and add measurements to the parts before sending it for cutting. I’ve looked at some free 2D CAD programs, and finally did all this work using QCad 3 Beta with worked great for me (I also tried LibreCAD but it didn’t work that well). All parts are cut from 4 mm thick material. Because I was worried that acrylic is too fragile and might break, I also ordered another set cut from plywood. In the end I build it from plywood because it was easier to glue (I was told acrylic requires a special glue). Btw. I found a great laser cutter service in Kraków and highly recommend it (www.ebbox.com.pl). It cost me only USD $26 for both sets ($16 acrylic + $10 plywood). Metal parts I bought all the M3 screws and nuts at local hardware store. Make sure to look for nylon lock (nyloc) nuts for the gripper because otherwise it unscrews and comes apart quickly. I couldn’t find local store with metal spacers and had to order them online (you’d need 11 x 47mm and 3 x 15mm). I think I paid less than USD $10 for all metal parts. Servos This arm uses five standards size servos to drive the arm itself, and two micro servos are used on the gripper. Author of the project used Modelcraft RS-2 Servo and Modelcraft ES-05 HT Servo. I had two Futaba S3001 servos laying around, and ordered additional TowerPro SG-5010 standard size servos and TowerPro SG90 micro servos. However it turned out that the SG90 won’t fit in the gripper so I had to replace it with a slightly smaller E-Sky EK2-0508 micro servo. Later it also turned out that Futaba servos make some strange noise while working so I swapped one with TowerPro SG-5010 which has higher torque (8kg / cm). I’ve also bought three servo extension cables. All servos cost me USD $45. Assembly The build process is not difficult but you need to think carefully about order of assembling it. You can do the base and upper arm first. Because two servos in the base are close together you need to put first with one piece of lower arm already connected before you put the second servo. Then you connect the upper arm and finally put the second piece of lower arm to hold it together. Gripper and base require some gluing so think it through too. Make sure to look closely at all the photos on Thingiverse (also other people copies) and read additional posts on jjshortcust’s blog: My mini servo grippers and completed robotic arm Multiply the robotic arm and electronics Here is also Rob’s copy cut from aluminum My assembled arm looks like this – I think it turned out really nice: Servo controller board The last piece of hardware I needed was an electronic board that would take command from PC and drive all seven servos. I could probably use Arduino for this task, and in fact there are several Arduino servo shields available (for example from Adafruit or Renbotics). However one problem is that most support only up to six servos, and second that their accuracy is limited by Arduino’s timer frequency. So instead I looked for dedicated servo controller and found a series of Maestro boards from Pololu. I picked the Pololu Mini Maestro 12-Channel USB Servo Controller. It has many nice features including native USB connection, high resolution pulses (0.25µs) with no jitter, built-in speed and acceleration control, and even scripting capability. Another cool feature is that besides servo control, each channel can be configured as either general input or output. So far I’m using seven channels so I still have five available to connect some sensors (for example distance sensor mounted on gripper might be useful). And last but important factor was that they have SDK in .NET – what more I could wish for! The board itself is very small – half of the size of Tic-Tac box. I picked one for about USD $35 in this store. Perhaps another good alternative would be the Phidgets Advanced Servo 8-Motor – but it is significantly more expensive at USD $87.30. The Maestro Controller Driver and Software package includes Maestro Control Center program with lets you immediately configure the board. For each servo I first figured out their move range and set the min/max limits. I played with setting the speed an acceleration values as well. Big issue for me was that there are two servos that control position of lower arm (shoulder joint), and both have to be moved at the same time. This is where the scripting feature of Pololu board turned out very helpful. I wrote a script that synchronizes position of second servo with first one – so now I only need to move one servo and other will follow automatically. This turned out tricky because I couldn’t find simple offset mapping of the move range for each servo – I had to divide it into several sub-ranges and map each individually. The scripting language is bit assembler-like but gets the job done. And there is even a runtime debugging and stack view available. Altogether I’m very happy with the Pololu Mini Maestro Servo Controller, and with this final piece I completed the build and was able to move my arm from the Meastro Control program. The total cost of my robotic arm was: $10 laser cut parts $10 metal parts $45 servos $35 servo controller ----------------------- $100 total So here you have all the information about the hardware. In next post I’ll start talking about the software that I wrote in Microsoft Robotics Developer Studio 4. Stay tuned!

Silverlight for Windows Embedded Tutorial (step 5 and a bit of Windows Phone 7)

- by Valter Minute

If you haven’t spent the last week in the middle of the Sahara desert or traveling on a sled in the north pole area you should have heard something about the launch of Windows Phone 7 Series (or Windows Phone Series 7, or Windows Series Phone 7 or something like that). Even if you are in the middle of the desert or somewhere around the north pole you may have been reached by the news, since it seems that WP7S (using the full name will kill my available bandwidth!) is generating a lot of buzz in the development and IT communities. One of the most important aspects of this new platform is that it will be programmed using a new set of tools and frameworks, completely different from the ones used on older releases of Windows Mobile (or SmartPhone, or PocketPC or whatever…). WP7S applications can be developed using Silverlight or XNA. If you want to learn something more about WP7S development you can download the preview of Charles Petzold’s book about it: http://www.charlespetzold.com/phone/index.html Charles Petzold is also the author of “Programming Windows”, the first book I ever read about programming on Windows (it was Windows 3.0 at that time!). The fact that even I was able to learn how to develop Windows application is a proof of the quality of Petzold’s work. This book is up to his standards and the 150pages preview is already rich in technical contents without being boring or complicated to understand. I may be able to become a Windows Phone developer thanks to mr. Petzold. Mr. Petzold uses some nice samples to introduce the basic concepts of Silverlight development on WP7S. On this new platform you’ll use managed code to develop your application, so those samples can’t be ported on Windows CE R3 as they are, but I would like to take one of the first samples (called “SilverlightTapHello1”) and adapt it to Silverlight for Windows Embedded to show that even plain old native code can be used to develop “cool” user interfaces! The sample shows the standard WP7S title header and a textbox with an hello world message inside it. When the user touches the textbox, it will change its color. When the user touches the background (Grid) behind it, its default color (plain old White) will be restored. Let’s see how we can implement the same features on our embedded device! I took the XAML code of the sample (you can download the book samples here: http://download.microsoft.com/download/1/D/B/1DB49641-3956-41F1-BAFA-A021673C709E/CodeSamples_DRAFTPreview_ProgrammingWindowsPhone7Series.zip) and changed it a little bit to remove references to WP7S or managed runtime. If you compare the resulting files you will see that I was able to keep all the resources inside the App.xaml files and the structure of MainPage.XAML almost intact. This is the Silverlight for Windows Embedded version of MainPage.XAML: <UserControl x:Class="SilverlightTapHello1.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phoneNavigation="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Navigation" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="800" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" Width="640" Height="480"> <Grid x:Name="LayoutRoot" Background="{StaticResource PhoneBackgroundBrush}"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions>  <Grid x:Name="TitleGrid" Grid.Row="0"> <TextBlock Text="SILVERLIGHT TAP HELLO #1" x:Name="textBlockPageTitle" Style="{StaticResource PhoneTextPageTitle1Style}"/> <TextBlock Text="main page" x:Name="textBlockListTitle" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid>  <Grid x:Name="ContentGrid" Grid.Row="1" MouseLeftButtonDown="ContentGrid_MouseButtonDown" Background="{StaticResource PhoneBackgroundBrush}"> <TextBlock x:Name="TextBlock" Text="Hello, Silverlight for Windows Embedded!" HorizontalAlignment="Center" VerticalAlignment="Center" /> </Grid> </Grid> </UserControl> If you compare it to the WP7S sample (not reported here to avoid any copyright issue) you’ll notice that I had to replace the original phoneNavigation:PhoneApplicationPage with UserControl as the root node. This make sense because there is not support for phone applications on CE 6. I also had to specify width and height of my main page (on the WP7S device this will be adjusted by the OS) and I had to replace the multi-touch event handler with the MouseLeftButtonDown event (no multitouch support for Windows CE R3, still). I also changed the hello message, of course. I used XAML2CPP to generate the boring part of our application and then added the initialization code to WinMain: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow) { if (!XamlRuntimeInitialize()) return -1; HRESULT retcode; IXRApplicationPtr app; if (FAILED(retcode=GetXRApplicationInstance(&app))) return -1; XRXamlSource dictsrc; dictsrc.SetResource(hInstance,TEXT("XAML"),IDR_XAML_App); if (FAILED(retcode=app->LoadResourceDictionary(&dictsrc,NULL))) return -1; MainPage page; if (FAILED(page.Init(hInstance,app))) return -1; UINT exitcode; if (FAILED(page.GetVisualHost()->StartDialog(&exitcode))) return -1; return exitcode; } You may have noticed that there is something different from the previous samples. I added the code to load a resource dictionary. Resources are an important feature of XAML that allows you to define some values that could be replaced inside any XAML file loaded by the runtime. You can use resources to define custom styles for your fonts, backgrounds, controls etc. and to support internationalization, by providing different strings for different languages. The rest of our WinMain isn’t that different. It creates an instances of our MainPage object and displays it. The MainPage class implements an event handler for the MouseLeftButtonDown event of the ContentGrid: class MainPage : public TMainPage<MainPage> { public: HRESULT ContentGrid_MouseButtonDown(IXRDependencyObject* source,XRMouseButtonEventArgs* args) { HRESULT retcode; IXRSolidColorBrushPtr brush; IXRApplicationPtr app; if (FAILED(retcode=GetXRApplicationInstance(&app))) return retcode; if (FAILED(retcode=app->CreateObject(IID_IXRSolidColorBrush,&brush))) return retcode; COLORREF color=RGBA(0xff,0xff,0xff,0xff); if (args->pOriginalSource==TextBlock) color=RGBA(rand()&0xFF,rand()&0xFF,rand()&0xFF,0xFF); if (FAILED(retcode=brush->SetColor(color))) return retcode; if (FAILED(retcode=TextBlock->SetForeground(brush))) return retcode; return S_OK; } }; As you can see this event is generated when a used clicks inside the grid or inside one of the objects it contains. Since our TextBlock is inside the grid, we don’t need to provide an event handler for its MouseLeftButtonDown event. We can just use the pOriginalSource member of the event arguments to check if the event was generated inside the textblock. If the event was generated inside the grid we create a white brush,if it’s inside the textblock we create some randomly colored brush. Notice that we need to use the RGBA macro to create colors, specifying also a transparency value for them. If we use the RGB macro the resulting color will have its Alpha channel set to zero and will be transparent. Using the SetForeground method we can change the color of our control. You can compare this to the managed code that you can find at page 40-41 of Petzold’s preview book and you’ll see that the native version isn’t much more complex than the managed one. As usual you can download the full code of the sample here: http://cid-9b7b0aefe3514dc5.skydrive.live.com/self.aspx/.Public/SilverlightTapHello1.zip And remember to pre-order Charles Petzold’s “Programming Windows Phone 7 series”, I bet it will be a best-seller!

WCF – interchangeable data-contract types

- by nmarun

In a WSDL based environment, unlike a CLR-world, we pass around the ‘state’ of an object and not the reference of an object. Well firstly, what does ‘state’ mean and does this also mean that we can send a struct where a class is expected (or vice-versa) as long as their ‘state’ is one and the same? Let’s see. So I have an operation contract defined as below: 1: [ServiceContract] 2: public interface ILearnWcfServiceExtend : ILearnWcfService 3: { 4: [OperationContract] 5: Employee SaveEmployee(Employee employee); 6: } 7: 8: [ServiceBehavior] 9: public class LearnWcfService : ILearnWcfServiceExtend 10: { 11: public Employee SaveEmployee(Employee employee) 12: { 13: employee.EmployeeId = 123; 14: return employee; 15: } 16: } Quite simplistic operation there (which translates to ‘absolutely no business value’). Now, the data contract Employee mentioned above is a struct. 1: public struct Employee 2: { 3: public int EmployeeId { get; set; } 4: 5: public string FName { get; set; } 6: } After compilation and consumption of this service, my proxy (in the Reference.cs file) looks like below (I’ve ignored the rest of the details just to avoid unwanted confusion): 1: public partial struct Employee : System.Runtime.Serialization.IExtensibleDataObject, System.ComponentModel.INotifyPropertyChanged I call the service with the code below: 1: private static void CallWcfService() 2: { 3: Employee employee = new Employee { FName = "A" }; 4: Console.WriteLine("IsValueType: {0}", employee.GetType().IsValueType); 5: Console.WriteLine("IsClass: {0}", employee.GetType().IsClass); 6: Console.WriteLine("Before calling the service: {0} - {1}", employee.EmployeeId, employee.FName); 7: employee = LearnWcfServiceClient.SaveEmployee(employee); 8: Console.WriteLine("Return from the service: {0} - {1}", employee.EmployeeId, employee.FName); 9: } The output is: I now change my Employee type from a struct to a class in the proxy class and run the application: 1: public partial class Employee : System.Runtime.Serialization.IExtensibleDataObject, System.ComponentModel.INotifyPropertyChanged { The output this time is: The state of an object implies towards its composition, the properties and the values of these properties and not based on whether it is a reference type (class) or a value type (struct). And as shown above, we’re actually passing an object by its state and not by reference. Continuing on the same topic of ‘type-interchangeability’, WCF treats two data contracts as equivalent if they have the same ‘wire-representation’. We can do so using the DataContract and DataMember attributes’ Name property. 1: [DataContract] 2: public struct Person 3: { 4: [DataMember] 5: public int Id { get; set; } 6: 7: [DataMember] 8: public string FirstName { get; set; } 9: } 10: 11: [DataContract(Name="Person")] 12: public class Employee 13: { 14: [DataMember(Name = "Id")] 15: public int EmployeeId { get; set; } 16: 17: [DataMember(Name="FirstName")] 18: public string FName { get; set; } 19: } I’ve created two data contracts with the exact same wire-representation. Just remember that the names and the types of data members need to match to be considered equivalent. The question then arises as to what gets generated in the proxy class. Despite us declaring two data contracts (Person and Employee), only one gets emitted – Person. This is because we’re saying that the Employee type has the same wire-representation as the Person type. Also that the signature of the SaveEmployee operation gets changed on the proxy side: 1: [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")] 2: [System.ServiceModel.ServiceContractAttribute(ConfigurationName="ServiceProxy.ILearnWcfServiceExtend")] 3: public interface ILearnWcfServiceExtend 4: { 5: [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ILearnWcfServiceExtend/SaveEmployee", ReplyAction="http://tempuri.org/ILearnWcfServiceExtend/SaveEmployeeResponse")] 6: ClientApplication.ServiceProxy.Person SaveEmployee(ClientApplication.ServiceProxy.Person employee); 7: } But, on the service side, the SaveEmployee still accepts and returns an Employee data contract. 1: [ServiceBehavior] 2: public class LearnWcfService : ILearnWcfServiceExtend 3: { 4: public Employee SaveEmployee(Employee employee) 5: { 6: employee.EmployeeId = 123; 7: return employee; 8: } 9: } Despite all these changes, our output remains the same as the last one: This is type-interchangeability at work! Here’s one more thing to ponder about. Our Person type is a struct and Employee type is a class. Then how is it that the Person type got emitted as a ‘class’ in the proxy? It’s worth mentioning that WSDL describes a type called Employee and does not say whether it is a class or a struct (see the SOAP message below): 1: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 2: xmlns:tem="http://tempuri.org/" 3: xmlns:ser="http://schemas.datacontract.org/2004/07/ServiceApplication"> 4: <soapenv:Header/> 5: <soapenv:Body> 6: <tem:SaveEmployee> 7:  8: <tem:employee> 9:  10: <ser:EmployeeId>?</ser:EmployeeId> 11:  12: <ser:FName>?</ser:FName> 13: </tem:employee> 14: </tem:SaveEmployee> 15: </soapenv:Body> 16: </soapenv:Envelope> There are some differences between how ‘Add Service Reference’ and the svcutil.exe generate the proxy class, but turns out both do some kind of reflection and determine the type of the data contract and emit the code accordingly. So since the Employee type is a class, the proxy ‘Person’ type gets generated as a class. In fact, reflecting on svcutil.exe application, you’ll see that there are a couple of places wherein a flag actually determines a type as a class or a struct. One example is in the ExportISerializableDataContract method in the System.Runtime.Serialization.CodeExporter class. Seems like these flags have a say in deciding whether the type gets emitted as a struct or a class. This behavior is different if you use the WSDL tool though. WSDL tool does not do any kind of reflection of the data contract / serialized type, it emits the type as a class by default. You can check this using the two command lines below: Note to self: Remember ‘state’ and type-interchangeability when traversing through the WSDL planet!

SQL SERVER – Repair a SQL Server Database Using a Transaction Log Explorer

- by Pinal Dave

In this blog, I’ll show how to use ApexSQL Log, a SQL Server transaction log viewer. You can download it for free, install, and play along. But first, let’s describe some disaster recovery scenarios where it’s useful. About SQL Server disaster recovery Along with database development and administration, you must work on a good recovery plan. Disasters do happen and no one’s immune. What you can do is take all actions needed to be ready for a disaster and go through it with minimal data loss and downtime. Besides creating a recovery plan, it’s necessary to have a list of steps that will be executed when a disaster occurs and to test them before a disaster. This way, you’ll know that the plan is good and viable. Testing can also be used as training for all team members, so they can all understand and execute it when the time comes. It will show how much time is needed to have your servers fully functional again and how much data you can lose in a real-life situation. If these don’t meet recovery-time and recovery-point objectives, the plan needs to be improved. Keep in mind that all major changes in environment configuration, business strategy, and recovery objectives require a new recovery plan testing, as these changes most probably induce a recovery plan changing and tweaking. What is a good SQL Server disaster recovery plan? A good SQL Server disaster recovery strategy starts with planning SQL Server database backups. An efficient strategy is to create a full database backup periodically. Between two successive full database backups, you can create differential database backups. It is essential is to create transaction log backups regularly between full database backups. Keep in mind that transaction log backups can be created only on databases in the full recovery model. In other words, a simple, but efficient backup strategy would be a full database backup every night, a transaction log backup every hour, or every 15 minutes. The frequency depends on how much data you can afford to lose and how busy the database is. Another option, instead of creating a full database backup every night, is to create a full database backup once a week (e.g. on Friday at midnight) and differential database backup every night until next Friday when you will create a full database backup again. Once you create your SQL Server database backup strategy, schedule the backups. You can do that easily using SQL Server maintenance plans. Why are transaction logs important? Transaction log backups contain transactions executed on a SQL Server database. They provide enough information to undo and redo the transactions and roll back or forward the database to a point in time. In SQL Server disaster recovery situations, transaction logs enable to repair a SQL Server database and bring it to the state before the disaster. Be aware that even with regular backups, there will be some data missing. These are the transactions made between the last transaction log backup and the time of the disaster. In some situations, to repair your SQL Server database it’s not necessary to re-create the database from its last backup. The database might still be online and all you need to do is roll back several transactions, such as wrong update, insert, or delete. The restore to a point in time feature is available in SQL Server, but for large databases, it is very time-consuming, as SQL Server first restores a full database backup, and then restores transaction log backups, one after another, up to the recovery point. During that time, the database is unavailable. This is where a SQL Server transaction log viewer can help. For optimal recovery, besides having a database in the full recovery model, it’s important that you haven’t manually truncated the online transaction log. This ensures that all transactions made after the last transaction log backup are still in the online transaction log. All you have to do is read and replay them. How to read a SQL Server transaction log? SQL Server doesn’t provide an option to read transaction logs. There are several SQL Server commands and functions that read the content of a transaction log file (fn_dblog, fn_dump_dblog, and DBCC PAGE), but they are undocumented. They require T-SQL knowledge, return a large number of not easy to read and understand columns, sometimes in binary or hexadecimal format. Another challenge is reading UPDATE statements, as it’s necessary to match it to a value in the MDF file. When you finally read the transactions executed, you have to create a script for it. How to easily repair a SQL database? The easiest solution is to use a transaction log reader that will not only read the transactions in the transaction log files, but also automatically create scripts for the read transactions. In the following example, I will show how to use ApexSQL Log to repair a SQL database after a crash. If a database has crashed and both MDF and LDF files are lost, you have to rely on the full database backup and all subsequent transaction log backups. In another scenario, the MDF file is lost, but the LDF file is available. First, restore the last full database backup on SQL Server using SQL Server Management Studio. I’ll name it Restored_AW2014. Then, start ApexSQL Log It will automatically detect all local servers. If not, click the icon right to the Server drop-down list, or just type in the SQL Server instance name. Select the Windows or SQL Server authentication type and select the Restored_AW2014 database from the database drop-down list. When all options are set, click Next. ApexSQL Log will show the online transaction log file. Now, click Add and add all transaction log backups created after the full database backup I used to restore the database. In case you don’t have transaction log backups, but the LDF file hasn’t been lost during the SQL Server disaster, add it using Add. To repair a SQL database to a point in time, ApexSQL Log needs to read and replay all the transactions in the transaction log backups (or the LDF file saved after the disaster). That’s why I selected the Whole transaction log option in the Filter setup. ApexSQL Log offers a range of various filters, which are useful when you need to read just specific transactions. You can filter transactions by the time of the transactions, operation type (e.g. to read only data inserts), table name, SQL Server login that made the transaction, etc. In this scenario, to repair a SQL database, I’ll check all filters and make sure that all transactions are included. In the Operations tab, select all schema operations (DDL). If you omit these, only the data changes will be read so if there were any schema changes, such as a new function created, or an existing table modified, they will be ignored and database will not be properly repaired. The data repair for modified tables will fail. In the Tables tab, I’ll make sure all tables are selected. I will uncheck the Show operations on dropped tables option, to reduce the number of transactions. Click Next. ApexSQL Log offers three options. Select Open results in grid, to get a user-friendly presentation of the transactions. As you can see, details are shown for every transaction, including the old and new values for updated columns, which are clearly highlighted. Now, select them all and then create a redo script by clicking the Create redo script icon in the menu. For a large number of transactions and in a critical situation, when acting fast is a must, I recommend using the Export results to file option. It will save some time, as the transactions will be directly scripted into a redo file, without showing them in the grid first. Select Generate reconstruction (REDO) script , change the output path if you want, and click Finish. After the redo T-SQL script is created, ApexSQL Log shows the redo script summary: The third option will create a command line statement for a batch file that you can use to schedule execution, which is not really applicable when you repair a SQL database, but quite useful in daily auditing scenarios. To repair your SQL database, all you have to do is execute the generated redo script using an integrated developer environment tool such as SQL Server Management Studio or any other, against the restored database. You can find more information about how to read SQL Server transaction logs and repair a SQL database on ApexSQL Solution center. There are solutions for various situations when data needs to be recovered, restored, or transactions rolled back.

SQL – Migrate Database from SQL Server to NuoDB – A Quick Tutorial

- by Pinal Dave

Data is growing exponentially and every organization with growing data is thinking of next big innovation in the world of Big Data. Big data is a indeed a future for every organization at one point of the time. Just like every other next big thing, big data has its own challenges and issues. The biggest challenge associated with the big data is to find the ideal platform which supports the scalability and growth of the data. If you are a regular reader of this blog, you must be familiar with NuoDB. I have been working with NuoDB for a while and their recent release is the best thus far. NuoDB is an elastically scalable SQL database that can run on local host, datacenter and cloud-based resources. A key feature of the product is that it does not require sharding (read more here). Last week, I was able to install NuoDB in less than 90 seconds and have explored their Explorer and Admin sections. You can read about my experiences in these posts: SQL – Step by Step Guide to Download and Install NuoDB – Getting Started with NuoDB SQL – Quick Start with Admin Sections of NuoDB – Manage NuoDB Database SQL – Quick Start with Explorer Sections of NuoDB – Query NuoDB Database Many SQL Authority readers have been following me in my journey to evaluate NuoDB. One of the frequently asked questions I’ve received from you is if there is any way to migrate data from SQL Server to NuoDB. The fact is that there is indeed a way to do so and NuoDB provides a fantastic tool which can help users to do it. NuoDB Migrator is a command line utility that supports the migration of Microsoft SQL Server, MySQL, Oracle, and PostgreSQL schemas and data to NuoDB. The migration to NuoDB is a three-step process: NuoDB Migrator generates a schema for a target NuoDB database It loads data into the target NuoDB database It dumps data from the source database Let’s see how we can migrate our data from SQL Server to NuoDB using a simple three-step approach. But before we do that we will create a sample database in MSSQL and later we will migrate the same database to NuoDB: Setup Step 1: Build a sample data CREATE DATABASE [Test]; CREATE TABLE [Department]( [DepartmentID] [smallint] NOT NULL, [Name] VARCHAR(100) NOT NULL, [GroupName] VARCHAR(100) NOT NULL, [ModifiedDate] [datetime] NOT NULL, CONSTRAINT [PK_Department_DepartmentID] PRIMARY KEY CLUSTERED ( [DepartmentID] ASC ) ) ON [PRIMARY]; INSERT INTO Department SELECT * FROM AdventureWorks2012.HumanResources.Department; Note that I am using the SQL Server AdventureWorks database to build this sample table but you can build this sample table any way you prefer. Setup Step 2: Install Java 64 bit Before you can begin the migration process to NuoDB, make sure you have 64-bit Java installed on your computer. This is due to the fact that the NuoDB Migrator tool is built in Java. You can download 64-bit Java for Windows, Mac OSX, or Linux from the following link: http://java.com/en/download/manual.jsp. One more thing to remember is that you make sure that the path in your environment settings is set to your JAVA_HOME directory or else the tool will not work. Here is how you can do it: Go to My Computer >> Right Click >> Select Properties >> Click on Advanced System Settings >> Click on Environment Variables >> Click on New and enter the following values. Variable Name: JAVA_HOME Variable Value: C:\Program Files\Java\jre7 Make sure you enter your Java installation directory in the Variable Value field. Setup Step 3: Install JDBC driver for SQL Server. There are two JDBC drivers available for SQL Server. Select the one you prefer to use by following one of the two links below: Microsoft JDBC Driver jTDS JDBC Driver In this example we will be using jTDS JDBC driver. Once you download the driver, move the driver to your NuoDB installation folder. In my case, I have moved the JAR file of the driver into the C:\Program Files\NuoDB\tools\migrator\jar folder as this is my NuoDB installation directory. Now we are all set to start the three-step migration process from SQL Server to NuoDB: Migration Step 1: NuoDB Schema Generation Here is the command I use to generate a schema of my SQL Server Database in NuoDB. First I go to the folder C:\Program Files\NuoDB\tools\migrator\bin and execute the nuodb-migrator.bat file. Note that my database name is ‘test’. Additionally my username and password is also ‘test’. You can see that my SQL Server database is running on my localhost on port 1433. Additionally, the schema of the table is ‘dbo’. nuodb-migrator schema –source.driver=net.sourceforge.jtds.jdbc.Driver –source.url=jdbc:jtds:sqlserver://localhost:1433/ –source.username=test –source.password=test –source.catalog=test –source.schema=dbo –output.path=/tmp/schema.sql The above script will generate a schema of all my SQL Server tables and will put it in the folder C:\tmp\schema.sql . You can open the schema.sql file and execute this file directly in your NuoDB instance. You can follow the link here to see how you can execute the SQL script in NuoDB. Please note that if you have not yet created the schema in the NuoDB database, you should create it before executing this step. Step 2: Generate the Dump File of the Data Once you have recreated your schema in NuoDB from SQL Server, the next step is very easy. Here we create a CSV format dump file, which will contain all the data from all the tables from the SQL Server database. The command to do so is very similar to the above command. Be aware that this step may take a bit of time based on your database size. nuodb-migrator dump –source.driver=net.sourceforge.jtds.jdbc.Driver –source.url=jdbc:jtds:sqlserver://localhost:1433/ –source.username=test –source.password=test –source.catalog=test –source.schema=dbo –output.type=csv –output.path=/tmp/dump.cat Once the above command is successfully executed you can find your CSV file in the C:\tmp\ folder. However, you do not have to do anything manually. The third and final step will take care of completing the migration process. Migration Step 3: Load the Data into NuoDB After building schema and taking a dump of the data, the very next step is essential and crucial. It will take the CSV file and load it into the NuoDB database. nuodb-migrator load –target.url=jdbc:com.nuodb://localhost:48004/mytest –target.schema=dbo –target.username=test –target.password=test –input.path=/tmp/dump.cat Please note that in the above script we are now targeting the NuoDB database, which we have already created with the name of “MyTest”. If the database does not exist, create it manually before executing the above script. I have kept the username and password as “test”, but please make sure that you create a more secure password for your database for security reasons. Voila! You’re Done That’s it. You are done. It took 3 setup and 3 migration steps to migrate your SQL Server database to NuoDB. You can now start exploring the database and build excellent, scale-out applications. In this blog post, I have done my best to come up with simple and easy process, which you can follow to migrate your app from SQL Server to NuoDB. Download NuoDB I strongly encourage you to download NuoDB and go through my 3-step migration tutorial from SQL Server to NuoDB. Additionally here are two very important blog post from NuoDB CTO Seth Proctor. He has written excellent blog posts on the concept of the Administrative Domains. NuoDB has this concept of an Administrative Domain, which is a collection of hosts that can run one or multiple databases. Each database has its own TEs and SMs, but all are managed within the Admin Console for that particular domain. http://www.nuodb.com/techblog/2013/03/11/getting-started-provisioning-a-domain/ http://www.nuodb.com/techblog/2013/03/14/getting-started-running-a-database/ Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: Big Data, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: NuoDB

Dynamically creating a Generic Type at Runtime

- by Rick Strahl

I learned something new today. Not uncommon, but it's a core .NET runtime feature I simply did not know although I know I've run into this issue a few times and worked around it in other ways. Today there was no working around it and a few folks on Twitter pointed me in the right direction. The question I ran into is: How do I create a type instance of a generic type when I have dynamically acquired the type at runtime? Yup it's not something that you do everyday, but when you're writing code that parses objects dynamically at runtime it comes up from time to time. In my case it's in the bowels of a custom JSON parser. After some thought triggered by a comment today I realized it would be fairly easy to implement two-way Dictionary parsing for most concrete dictionary types. I could use a custom Dictionary serialization format that serializes as an array of key/value objects. Basically I can use a custom type (that matches the JSON signature) to hold my parsed dictionary data and then add it to the actual dictionary when parsing is complete. Generic Types at Runtime One issue that came up in the process was how to figure out what type the Dictionary<K,V> generic parameters take. Reflection actually makes it fairly easy to figure out generic types at runtime with code like this: if (arrayType.GetInterface("IDictionary") != null) { if (arrayType.IsGenericType) { var keyType = arrayType.GetGenericArguments()[0]; var valueType = arrayType.GetGenericArguments()[1]; … } } The GetArrayType method gets passed a type instance that is the array or array-like object that is rendered in JSON as an array (which includes IList, IDictionary, IDataReader and a few others). In my case the type passed would be something like Dictionary<string, CustomerEntity>. So I know what the parent container class type is. Based on the the container type using it's then possible to use GetGenericTypeArguments() to retrieve all the generic types in sequential order of definition (ie. string, CustomerEntity). That's the easy part. Creating a Generic Type and Providing Generic Parameters at RunTime The next problem is how do I get a concrete type instance for the generic type? I know what the type name and I have a type instance is but it's generic, so how do I get a type reference to keyvaluepair<K,V> that is specific to the keyType and valueType above? Here are a couple of things that come to mind but that don't work (and yes I tried that unsuccessfully first): Type elementType = typeof(keyvalue<keyType, valueType>); Type elementType = typeof(keyvalue<typeof(keyType), typeof(valueType)>); The problem is that this explicit syntax expects a type literal not some dynamic runtime value, so both of the above won't even compile. I turns out the way to create a generic type at runtime is using a fancy bit of syntax that until today I was completely unaware of: Type elementType = typeof(keyvalue<,>).MakeGenericType(keyType, valueType); The key is the type(keyvalue<,>) bit which looks weird at best. It works however and produces a non-generic type reference. You can see the difference between the full generic type and the non-typed (?) generic type in the debugger: The nonGenericType doesn't show any type specialization, while the elementType type shows the string, CustomerEntity (truncated above) in the type name. Once the full type reference exists (elementType) it's then easy to create an instance. In my case the parser parses through the JSON and when it completes parsing the value/object it creates a new keyvalue<T,V> instance. Now that I know the element type that's pretty trivial with: // Objects start out null until we find the opening tag resultObject = Activator.CreateInstance(elementType); Here the result object is picked up by the JSON array parser which creates an instance of the child object (keyvalue<K,V>) and then parses and assigns values from the JSON document using the types key/value property signature. Internally the parser then takes each individually parsed item and adds it to a list of List<keyvalue<K,V>> items. Parsing through a Generic type when you only have Runtime Type Information When parsing of the JSON array is done, the List needs to be turned into a defacto Dictionary<K,V>. This should be easy since I know that I'm dealing with an IDictionary, and I know the generic types for the key and value. The problem is again though that this needs to happen at runtime which would mean using several Convert.ChangeType() calls in the code to dynamically cast at runtime. Yuk. In the end I decided the easier and probably only slightly slower way to do this is a to use the dynamic type to collect the items and assign them to avoid all the dynamic casting madness: else if (IsIDictionary) { IDictionary dict = Activator.CreateInstance(arrayType) as IDictionary; foreach (dynamic item in items) { dict.Add(item.key, item.value); } return dict; } This code creates an instance of the generic dictionary type first, then loops through all of my custom keyvalue<K,V> items and assigns them to the actual dictionary. By using Dynamic here I can side step all the explicit type conversions that would be required in the three highlighted areas (not to mention that this nested method doesn't have access to the dictionary item generic types here). Static <- -> Dynamic Dynamic casting in a static language like C# is a bitch to say the least. This is one of the few times when I've cursed static typing and the arcane syntax that's required to coax types into the right format. It works but it's pretty nasty code. If it weren't for dynamic that last bit of code would have been a pretty ugly as well with a bunch of Convert.ChangeType() calls to litter the code. Fortunately this type of type convulsion is rather rare and reserved for system level code. It's not every day that you create a string to object parser after all :-)© Rick Strahl, West Wind Technologies, 2005-2011Posted in .NET CSharp Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

SQL Server Master class winner

- by Testas

The winner of the SQL Server MasterClass competition courtesy of the UK SQL Server User Group and SQL Server Magazine! Steve Hindmarsh There is still time to register for the seminar yourself at: www.regonline.co.uk/kimtrippsql More information about the seminar Where: Radisson Edwardian Heathrow Hotel, London When: Thursday 17th June 2010 This one-day MasterClass will focus on many of the top issues companies face when implementing and maintaining a SQL Server-based solution. In the case where a company has no dedicated DBA, IT managers sometimes struggle to keep the data tier performing well and the data available. This can be especially troublesome when the development team is unfamiliar with the affect application design choices have on database performance. The Microsoft SQL Server MasterClass 2010 is presented by Paul S. Randal and Kimberly L. Tripp, two of the most experienced and respected people in the SQL Server world. Together they have over 30 years combined experience working with SQL Server in the field, and on the SQL Server product team itself. This is a unique opportunity to hear them present at a UK event which will: Debunk many of the ingrained misconceptions around SQL Server's behaviour Show you disaster recovery techniques critical to preserving your company's life-blood - the data Explain how a common application design pattern can wreak havoc in the database Walk through the top-10 points to follow around operations and maintenance for a well-performing and available data tier! Please Note: Agenda may be subject to change Sessions Abstracts KEYNOTE: Bridging the Gap Between Development and Production Applications are commonly developed with little regard for how design choices will affect performance in production. This is often because developers don't realize the implications of their design on how SQL Server will be able to handle a high workload (e.g. blocking, fragmentation) and/or because there's no full-time trained DBA that can recognize production problems and help educate developers. The keynote sets the stage for the rest of the day. Discussing some of the issues that can arise, explaining how some can be avoided and highlighting some of the features in SQL 2008 that can help developers and DBAs make better use of SQL Server, and troubleshoot when things go wrong. SESSION ONE: SQL Server Mythbusters It's amazing how many myths and misconceptions have sprung up and persisted over the years about SQL Server - after many years helping people out on forums, newsgroups, and customer engagements, Paul and Kimberly have heard it all. Are there really non-logged operations? Can interrupting shrinks or rebuilds cause corruption? Can you override the server's MAXDOP setting? Will the server always do a table-scan to get a row count? Many myths lead to poor design choices and inappropriate maintenance practices so these are just a few of many, many myths that Paul and Kimberly will debunk in this fast-paced session on how SQL Server operates and should be managed and maintained. SESSION TWO: Database Recovery Techniques Demo-Fest Even if a company has a disaster recovery strategy in place, they need to practice to make sure that the plan will work when a disaster does strike. In this fast-paced demo session Paul and Kimberly will repeatedly do nasty things to databases and then show how they are recovered - demonstrating many techniques that can be used in production for disaster recovery. Not for the faint-hearted! SESSION THREE: GUIDs: Use, Abuse, and How To Move Forward Since the addition of the GUID (Microsoft’s implementation of the UUID), my life as a consultant and "tuner" has been busy. I’ve seen databases designed with GUID keys run fairly well with small workloads but completely fall over and fail because they just cannot scale. And, I know why GUIDs are chosen - it simplifies the handling of parent/child rows in your batches so you can reduce round-trips or avoid dealing with identity values. And, yes, sometimes it's even for distributed databases and/or security that GUIDs are chosen. I'm not entirely against ever using a GUID but overusing and abusing GUIDs just has to be stopped! Please, please, please let me give you better solutions and explanations on how to deal with your parent/child rows, round-trips and clustering keys! SESSION 4: Essential Database Maintenance In this session, Paul and Kimberly will run you through their top-ten database maintenance recommendations, with a lot of tips and tricks along the way. These are distilled from almost 30 years combined experience working with SQL Server customers and are geared towards making your databases more performant, more available, and more easily managed (to save you time!). Everything in this session will be practical and applicable to a wide variety of databases. Topics covered include: backups, shrinks, fragmentation, statistics, and much more! Focus will be on 2005 but we'll explain some of the key differences for 2000 and 2008 as well. Speaker Biographies Kimberley L. Tripp Paul and Kimberly are a husband-and-wife team who own and run SQLskills.com, a world-renowned SQL Server consulting and training company. They are both SQL Server MVPs and Microsoft Regional Directors, with over 30 years of combined experience on SQL Server. Paul worked on the SQL Server team for nine years in development and management roles, writing many of the DBCC commands, and ultimately with responsibility for core Storage Engine for SQL Server 2008. Paul writes extensively on his blog (SQLskills.com/blogs/Paul) and for TechNet Magazine, for which he is also a Contributing Editor. Kimberly worked on the SQL Server team in the early 1990s as a tester and writer before leaving to found SQLskills and embrace her passion for teaching and consulting. Kimberly has been a staple at worldwide conferences since she first presented at TechEd in 1996, and she blogs at SQLskills.com/blogs/Kimberly. They have written Microsoft whitepapers and books for SQL Server 2000, 2005 and 2008, and are regular, top-rated presenters worldwide on database maintenance, high availability, disaster recovery, performance tuning, and SQL Server internals. Together they teach the SQL MCM certification and throughout Microsoft.In their spare time, they like to find frogfish in remote corners of the world. Speaker Testimonials "To call them good trainers is an epic understatement. They know how to deliver technical material in ways that illustrate it well. I had to stop Paul at one point and ask him how long it took to build a particular slide because the animations were so good at conveying a hard-to-describe process." "These are not beginner presenters, and they put an extreme amount of preparation and attention to detail into everything that they do. Completely, utterly professional." "When it comes to the instructors themselves, Kimberly and Paul simply have no equal. Not only are they both ultimate authorities, but they have endless enthusiasm about the material, and spot on delivery. If either ever got tired they never showed it, even after going all day and all week. We witnessed countless demos over the course of the week, some extremely involved, multi-step processes, and I can’t recall one that didn’t go the way it was supposed to." "You might think that with this extreme level of skill comes extreme levels of egotism and lack of patience. Nothing could be further from the truth. ... They simply know how to teach, and are approachable, humble, and patient." "The experience Paul and Kimberly have had with real live customers yields a lot more information and things to watch out for than you'd ever get from documentation alone." “Kimberly, I just wanted to send you an email to let you know how awesome you are! I have applied some of your indexing strategies to our website’s homegrown CMS and we are experiencing a significant performance increase. WOW....amazing tips delivered in an exciting way! Thanks again”

A pseudo-listener for AlwaysOn Availability Groups for SQL Server virtual machines running in Azure

- by MikeD

I am involved in a project that is implementing SharePoint 2013 on virtual machines hosted in Azure. The back end data tier consists of two Azure VMs running SQL Server 2012, with the SharePoint databases contained in an AlwaysOn Availability Group. I used this "Tutorial: AlwaysOn Availability Groups in Windows Azure (GUI)" to help me implement this setup.Because Azure DHCP will not assign multiple unique IP addresses to the same VM, having an AG Listener in Azure is not currently supported. I wanted to figure out another mechanism to support a "pseudo listener" of some sort. First, I created a CNAME (alias) record in the DNS zone with a short TTL (time to live) of 5 minutes (I may yet make this even shorter). The record represents a logical name (let's say the alias is SPSQL) of the server to connect to for the databases in the availability group (AG). When Server1 was hosting the primary replica of the AG, I would set the CNAME of SPSQL to be SERVER1. When the AG failed over to Server1, I wanted to set the CNAME to SERVER2. Seemed simple enough.(It's important to point out that the connection strings for my SharePoint services should use the CNAME alias, and not the actual server name. This whole thing falls apart otherwise.)To accomplish this, I created identical SQL Agent Jobs on Server1 and Server2, with two steps:1. Step 1: Determine if this server is hosting the primary replica.This is a TSQL step using this script:declare @agName sysname = 'AGTest'set nocount on declare @primaryReplica sysnameselect @primaryReplica = agState.primary_replicafrom sys.dm_hadr_availability_group_states agState join sys.availability_groups ag on agstate.group_id = ag.group_id where ag.name = @AGname if not exists( select * from sys.dm_hadr_availability_group_states agState join sys.availability_groups ag on agstate.group_id = ag.group_id where @@Servername = agstate.primary_replica and ag.name = @AGname)begin raiserror ('Primary replica of %s is not hosted on %s, it is hosted on %s',17,1,@Agname, @@Servername, @primaryReplica) endThis script determines if the primary replica value of the AG group is the same as the server name, which means that our server is hosting the current AG (you should update the value of the @AgName variable to the name of your AG). If this is true, I want the DNS alias to point to this server. If the current server is not hosting the primary replica, then the script raises an error. Also, if the script can't be executed because it cannot connect to the server, that also will generate an error. For the job step settings, I set the On Failure option to "Quit the job reporting success". The next step in the job will set the DNS alias to this server name, and I only want to do that if I know that it is the current primary replica, otherwise I don't want to do anything. I also include the step output in the job history so I can see the error message.Job Step 2: Update the CNAME entry in DNS with this server's name.I used a PowerShell script to accomplish this:$cname = "SPSQL.contoso.com"$query = "Select * from MicrosoftDNS_CNAMEType"$dns1 = "dc01.contoso.com"$dns2 = "dc02.contoso.com"if ((Test-Connection -ComputerName $dns1 -Count 1 -Quiet) -eq $true){ $dnsServer = $dns1}elseif ((Test-Connection -ComputerName $dns2 -Count 1 -Quiet) -eq $true) { $dnsServer = $dns2}else{ $msg = "Unable to connect to DNS servers: " + $dns1 + ", " + $dns2 Throw $msg}$record = Get-WmiObject -Namespace "root\microsoftdns" -Query $query -ComputerName $dnsServer | ? { $_.Ownername -match $cname }$thisServer = [System.Net.Dns]::GetHostEntry("LocalHost").HostName + "."$currentServer = $record.RecordData if ($currentServer -eq $thisServer ) { $cname + " CNAME is up to date: " + $currentServer}else{ $cname + " CNAME is being updated to " + $thisServer + ". It was " + $currentServer $record.RecordData = $thisServer $record.put()}This script does a few things:finds a responsive domain controller (Test-Connection does a ping and returns a Boolean value if you specify the -Quiet parameter)makes a WMI call to the domain controller to get the current CNAME record value (Get-WmiObject)gets the FQDN of this server (GetHostEntry)checks if the CNAME record is correct and updates it if necessary(You should update the values of the variables $cname, $dns1 and $dns2 for your environment.)Since my domain controllers are also hosted in Azure VMs, either one of them could be down at any point in time, so I need to find a DC that is responsive before attempting the DNS call. The other little thing here is that the CNAME record contains the FQDN of a machine, plus it ends with a period. So the comparison of the CNAME record has to take the trailing period into account. When I tested this step, I was getting ACCESS DENIED responses from PowerShell for the Get-WmiObject cmdlet that does a remote lookup on the DC. This occurred because the SQL Agent service account was not a member of the Domain Admins group, so I decided to create a SQL Credential to store the credentials for a domain administrator account and use it as a PowerShell proxy (rather than give the service account Domain Admins membership).In SQL Management Studio, right click on the Credentials node (under the server's Security node), and choose New Credential...Then, under SQL Agent-->Proxies, right click on the PowerShell node and choose New Proxy...Finally, in the job step properties for the PowerShell step, select the new proxy in the Run As drop down.I created this two step Job on both nodes of the Availability Group, but if you had more than two nodes, just create the same job on all the servers. I set the schedule for the job to execute every minute.When the server that is hosting the primary replica is running the job, the job history looks like this:The job history on the secondary server looks like this: When a failover occurs, the SQL Agent job on the new primary replica will detect that the CNAME needs to be updated within a minute. Based on the TTL of the CNAME (which I said at the beginning was 5 minutes), the SharePoint servers will get the new alias within five minutes and should be able to reconnect. I may want to shorten up the TTL to reduce the time it takes for the client connections to use the new alias. Using a DNS CNAME and a SQL Agent Job on all servers hosting AG replicas, I was able to create a pseudo-listener to automatically change the name of the server that was hosting the primary replica, for a scenario where I cannot use a regular AG listener (in this case, because the servers are all hosted in Azure).

Udev webcam rule read, but not respected?

- by user89305

I have two usb-webcams on them machine, but at bot they some switch /dev/video number. The solution to this problem seems to be new udev rule. I have added this rule in/etc/udev/rules.d/jj-video.rules: Fix webcam 1 KERNEL=="video1", SUBSYSTEM=="video4linux", SUBSYSTEMS=="usb", ATTRS{idVendor}=="1d6b", ATTRS{idProduct}=="0001", SYMLINK+="webcam1" Fix webcam 2 KERNEL=="video2", SUBSYSTEM=="video4linux", ATTR{name}=="Logitech QuickCam Pro 3000", KERNELS=="0000:00:1d.0", SUBSYSTEMS=="pci", DRIVERS=="uhci_hcd", ATTRS{vendor}=="0x8086", ATTRS##{device}=="0x2658", SYMLINK+="webcam2" but the symlinks are not created. I have tried many different combinations in this file. The present ones are just my lates attempts. I found the parameters in: jjk@eee-old:~$ udevadm info -a -p $(udevadm info -q path -p /class/video4linux/video1) Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device. looking at device '/devices/pci0000:00/0000:00:1d.0/usb2/2-2/2-2:1.0/video4linux/video1': KERNEL=="video1" SUBSYSTEM=="video4linux" DRIVER=="" ATTR{name}=="Logitech QuickCam Pro 3000" ATTR{index}=="0" ATTR{button}=="0" looking at parent device '/devices/pci0000:00/0000:00:1d.0/usb2/2-2/2-2:1.0': KERNELS=="2-2:1.0" SUBSYSTEMS=="usb" DRIVERS=="Philips webcam" ATTRS{bInterfaceNumber}=="00" ATTRS{bAlternateSetting}==" 9" ATTRS{bNumEndpoints}=="02" ATTRS{bInterfaceClass}=="0a" ATTRS{bInterfaceSubClass}=="ff" ATTRS{bInterfaceProtocol}=="00" ATTRS{supports_autosuspend}=="0" looking at parent device '/devices/pci0000:00/0000:00:1d.0/usb2/2-2': KERNELS=="2-2" SUBSYSTEMS=="usb" DRIVERS=="usb" ATTRS{configuration}=="" ATTRS{bNumInterfaces}==" 3" ATTRS{bConfigurationValue}=="1" ATTRS{bmAttributes}=="a0" ATTRS{bMaxPower}=="500mA" ATTRS{urbnum}=="371076" ATTRS{idVendor}=="046d" ATTRS{idProduct}=="08b0" ATTRS{bcdDevice}=="0002" ATTRS{bDeviceClass}=="00" ATTRS{bDeviceSubClass}=="00" ATTRS{bDeviceProtocol}=="00" ATTRS{bNumConfigurations}=="1" ATTRS{bMaxPacketSize0}=="8" ATTRS{speed}=="12" ATTRS{busnum}=="2" ATTRS{devnum}=="2" ATTRS{devpath}=="2" ATTRS{version}==" 1.10" ATTRS{maxchild}=="0" ATTRS{quirks}=="0x0" ATTRS{avoid_reset_quirk}=="0" ATTRS{authorized}=="1" ATTRS{serial}=="01402100A5000000" looking at parent device '/devices/pci0000:00/0000:00:1d.0/usb2': KERNELS=="usb2" SUBSYSTEMS=="usb" DRIVERS=="usb" ATTRS{configuration}=="" ATTRS{bNumInterfaces}==" 1" ATTRS{bConfigurationValue}=="1" ATTRS{bmAttributes}=="e0" ATTRS{bMaxPower}==" 0mA" ATTRS{urbnum}=="34" ATTRS{idVendor}=="1d6b" ATTRS{idProduct}=="0001" ATTRS{bcdDevice}=="0302" ATTRS{bDeviceClass}=="09" ATTRS{bDeviceSubClass}=="00" ATTRS{bDeviceProtocol}=="00" ATTRS{bNumConfigurations}=="1" ATTRS{bMaxPacketSize0}=="64" ATTRS{speed}=="12" ATTRS{busnum}=="2" ATTRS{devnum}=="1" ATTRS{devpath}=="0" ATTRS{version}==" 1.10" ATTRS{maxchild}=="2" ATTRS{quirks}=="0x0" ATTRS{avoid_reset_quirk}=="0" ATTRS{authorized}=="1" ATTRS{manufacturer}=="Linux 3.2.0-29-generic uhci_hcd" ATTRS{product}=="UHCI Host Controller" ATTRS{serial}=="0000:00:1d.0" ATTRS{authorized_default}=="1" looking at parent device '/devices/pci0000:00/0000:00:1d.0': KERNELS=="0000:00:1d.0" SUBSYSTEMS=="pci" DRIVERS=="uhci_hcd" ATTRS{vendor}=="0x8086" ATTRS{device}=="0x2658" ATTRS{subsystem_vendor}=="0x1043" ATTRS{subsystem_device}=="0x82d8" ATTRS{class}=="0x0c0300" ATTRS{irq}=="23" ATTRS{local_cpus}=="ff" ATTRS{local_cpulist}=="0-7" ATTRS{dma_mask_bits}=="32" ATTRS{consistent_dma_mask_bits}=="32" ATTRS{broken_parity_status}=="0" ATTRS{msi_bus}=="" looking at parent device '/devices/pci0000:00': KERNELS=="pci0000:00" SUBSYSTEMS=="" DRIVERS=="" jjk@eee-old:~$ And tested the setup: sudo udevadm --debug test /sys/class/video4linux/video1 main: runtime dir '/run/udev' run_command: calling: test adm_test: version 175 This program is for debugging only, it does not run any program, specified by a RUN key.

Simple way of converting server side objects into client side using JSON serialization for asp.net websites

- by anil.kasalanati

Introduction:- With the growth of Web2.0 and the need for faster user experience the spotlight has shifted onto javascript based applications built using REST pattern or asp.net AJAX Pagerequest manager. And when we are working with javascript wouldn’t it be much better if we could create objects in an OOAD way and easily push it to the client side. Following are the reasons why you would push the server side objects onto client side - Easy availability of the complex object. - Use C# compiler and rick intellisense to create and maintain the objects but use them in the javascript. You could run code analysis etc. - Reduce the number of calls we make to the server side by loading data on the pageload. I would like to explain about the 3rd point because that proved to be highly beneficial to me when I was fixing the performance issues of a major website. There could be a scenario where in you be making multiple AJAX based webrequestmanager calls in order to get the same response in a single page. This happens in the case of widget based framework when all the widgets are independent but they need some common information available in the framework to load the data. So instead of making n multiple calls we could load the data needed during pageload. The above picture shows the scenario where in all the widgets need the common information and then call GetData webservice on the server side. Ofcourse the result can be cached on the client side but a better solution would be to avoid the call completely. In order to do that we need to JSONSerialize the content and send it in the DOM. Example:- I have developed a simple application to demonstrate the idea and I would explaining that in detail here. The class called SimpleClass would be sent as serialized JSON to the client side . And this inherits from the base class which has the implementation for the GetJSONString method. You can create a single base class and all the object which need to be pushed to the client side can inherit from that class. The important thing to note is that the class should be annotated with DataContract attribute and the methods should have the Data Member attribute. This is needed by the .Net DataContractSerializer and this follows the opt-in mode so if you want to send an attribute to the client side then you need to annotate the DataMember attribute. So if I didn’t want to send the Result I would simple remove the DataMember attribute. This is default WCF/.Net 3.5 stuff but it provides the flexibility of have a fullfledged object on the server side but sending a smaller object to the client side. Sometimes you may hide some values due to security constraints. And thing you will notice is that I have marked the class as Serializable so that it can be stored in the Session and used in webfarm deployment scenarios. Following is the implementation of the base class – This implements the default DataContractJsonSerializer and for more information or customization refer to following blogs – http://softcero.blogspot.com/2010/03/optimizing-net-json-serializing-and-ii.html http://weblogs.asp.net/gunnarpeipman/archive/2010/12/28/asp-net-serializing-and-deserializing-json-objects.aspx The next part is pretty simple, I just need to inject this object into the aspx page. And in the aspx markup I have the following line – <script type="text/javascript"> var data =(<%=SimpleClassJSON %>); alert(data.ResultText); </script> This will output the content as JSON into the variable data and this can be any element in the DOM. And you can verify the element by checking data in the Firebug console. Design Consideration – If you have a lot of javascripts then you need to think about using Script # and you can write javascript in C#. Refer to Nikhil’s blog – http://projects.nikhilk.net/ScriptSharp Ensure that you are taking security into consideration while exposing server side objects on to client side. I have seen application exposing passwords, secret key so it is not a good practice. The application can be tested using the following url – http://techconsulting.vpscustomer.com/Samples/JsonTest.aspx The source code is available at http://techconsulting.vpscustomer.com/Source/HistoryTest.zip

ODEE Green Field (Windows) Part 5 - Deployment and Validation

- by AndyL-Oracle

And here we are, almost finished with our installation of Oracle Documaker Enterprise Edition ("ODEE") in a Windows green field environment. Let's recap what we've done so far: In part 1, I went over the basic process that I intended to show with installing an ODEE on a green field server. I walked you through the basic installation of Oracle 11g database In part 2, I covered the installation of WebLogic application server. In part 3, I showed you how to install SOA Suite for WebLogic. In part 4, we did the first part of the installation of ODEE itself. What remains after all of that, is the deployment of the ODEE components onto the database and application server - so let's get to it! DATABASE First, we'll deploy the schemas to the database. The schemas are created during the ODEE installation according to the responses provided during the install process. To deploy the schemas, you'll need to login to the database server in your green field environment. Open a command line and CD into ODEE_HOME\documaker\database\oracle11g.Run SQLPLUS as SYSDBA and execute dmkr_admin.sql: sqlplus / as sysdba @dmkr_admin.sql Execute dmkr_asline.sql, dmkr_admin_correspondence_example.sql. If you require additional languages, run the appropriate SQL scripts (e.g. dmkr_asline_es.sql for Spanish). APPLICATION SERVER Next, we'll deploy the WebLogic domain and it's components - Documaker web services, Documaker Interactive, Documaker dashboard, and more. To deploy the components, you'll need to login to the application server in your green field environment. 1. Open Windows Explorer and navigate to ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts.2. Using a text editor such as Notepad++, modify weblogic_installation_properties and set location of MIDDLEWARE_HOME and ODEE HOME. If you have used the defaults you’ll probably need to change the E: to C: and that’s it. Save the changes.3. Continuing in the same directory, use your text editor to modify set_middleware_env.cmd and set the drive and path to MIDDLEWARE_HOME. If you have used the defaults you’ll probably need to just change E: to C: and that’s it. Save the changes.4. In the same directory, execute wls_create_domain.cmd by double-clicking it. This should run to completion. If it does not, review any errors and correct them, and rerun the script.5. In the same directory, execute wls_add_correspondence.cmd by double-clicking it - again this should run to completion. 6. Next, we'll start the AdminServer - this is the main WebLogic domain server. To start it, use Windows Explorer and navigate to MIDDLEWARE_HOME\user_projects\domains\idocumaker_domain. Double-click startWebLogic.cmd and the server startup will begin. Once you see output that indicates that the server status changed to RUNNING you may proceed. a. Note: if you saw database connection errors, you probably didn’t make sure your database name and connection type match. You can change this manually in the WebLogic Console. Open a browser and navigate to http://localhost:7001/console (replace localhost with the name of your application server host if you aren't opening the browser on the server), and login with the the weblogic credential you provided in the ODEE installation process. b. Once you're logged in, open Services?Data Sources. Select dmkr_admin and click Connection Pool. c. The end of the URL should match the connection type you chose. If you chose ServiceName, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<serviceName> and if you chose SID, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<SIDname> d. An example serviceName is a fully qualified DNS-style name, e.g. "idmaker.us.oracle.com". (It does not need to actually resolve in DNS). An example SID is just a name, e.g. IDMAKER. e. Save the change and repeat for the data source dmkr_asline. f. You will also need to make the same changes in the ODEE_HOME/documaker/docfactory/config/context/.bindings file - open the file in a text editor, locate the URL lines and make the appropriate change, then save the file. 7. Back in the ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts directory, execute create_users_groups.cmd. 8. In the same directory, execute create_users_groups_correspondence_example.cmd. 9. Open a browser and navigate to http://localhost:7001/jpsquery. Replace localhost with the name of your application server host if you aren't running the browser on the application server. If you changed the default port for the AdminServer from 7001, use the port you changed it to. You should see output like this: 10. Start the WebLogic managed servers by opening a command prompt and navigating to MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/. When you start the servers listed below, you will be prompted to enter the WebLogic credentials to start the server. You can prevent this by providing the credential in the startManagedwebLogic.cmd file for the WLS_USER and WLS_PASS values. Note that the credential will be stored in cleartext. To start the server, type in the command shown. a. Start the JMS Server: ./startManagedWebLogic.cmd jms_server b. Start Dashboard/Documaker Administrator: ./startManagedWebLogic.cmd dmkr_server c. Start Documaker Interactive for Correspondence: ./startManagedWebLogic.cmd idm_server SOA Composites If you're planning on testing out the approval process components of BPEL that can be used with Documaker Interactive, then use the following steps to deploy the SOA composites. If you're not going to use BPEL, you can skip to the next section.1. Stop the servers listed in the previous section (Step 10) in the reverse order that they were started.2. Run the Domain configuration command: navigate to and execute MIDDLEWARE_HOME/wlserver_10.3/common/bin/config.cmd.3. Select Extend and click next. 4. Select the iDocumaker Domain and click Next. 5. Select the Oracle SOA Suite – 11.1.1.0 (this may automatically select other components which is OK). Click Next. 6. View the Configure JDBC resources screen. You should not make any changes. Click Next. 7. Check both connections and click Test Connections. After successful test, click Next. If the tests fail, something is broken. Go back to configure JDBC resources and check your service name/SID. 8. Check all schemas. Set a password (will be the same for all schemas). Enter the database information (service name, host name, port). Click Next. 9. Connections should test successfully. If not, go back and fix any errors. Click Next. 10. Click Next to pass through Optional Configuration. 11. Click Extend. 12. Click Done. 13. Open a terminal window and navigate to/execute: ODEE_HOME/documaker/j2ee/weblogic/oracle11g/bpel/antbuild.cmd14. Start the WebLogic Servers – AdminServer, jms_server, dmkr_server, idm_server. If you forgot how to do this, see the previous section Step 10. Note: if you previously changed the startManagedWebLogic.cmd script for WLS_USER and WLS_PASS you will need to make those changes again. 15. Start the WebLogic server soa_server1: MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/startManagedWebLogic.cmd soa_server116. Open a browser to http://localhost:7001/console and login. 17. Navigate to Services?Data Sources and select DMKR_ASLINE. 18. Click the Targets tab. Check soa_server1, then click Save. Repeat for the DMKR_ADMIN data source. 19. Open a command prompt and navigate to ODEE_HOME/j2ee/weblogic/oracle11g/scripts, then execute deploy_soa.cmd. That's it! (As if that wasn't enough?) DOCUMAKER Deploy the sample MRL resources by navigating to/executing ODEE_HOME/documaker/mstrres/dmres/deploysamplemrl.bat. You should see approximately 500 resources deployed into the database. Start the Factory Services. Start?Run?services.msc. Locate the service named "ODDF xxxx" and right-click, select Start. Note that each Assembly Line has a separate Factory setup, including its own Factory service and Docupresentment service. The services are named for the assembly line and the machine on which they are installed (because you could have multiple machines servicing a single assembly line, so this allows for easy scripting to control all the services if you choose to do so. Repeat for the Docupresentment service. Note that each Assembly Line has a separate Docupresentment. Using Windows Explorer, navigate to ODEE_HOME/documaker/mstrres/dmres/input and select one of the XML files, and copy it into ODEE_HOME/documaker/hotdirectory. Note: if you chose a different hot directory during installation, copy the file there instead. Momentarily you should see the XML file disappear! Open browser and navigate to http://localhost:10001/DocumakerDashboard (previous versions 12.0-12.2 use http://localhost:10001/dashboard) and verify that job processed successfully. Note that some transactions may fail if you do not have a properly configured email server, and this is ok. You can set up a simple SMTP server (just search the internet for "SMTP developer" and you'll get several to choose from. So... that's it? Where are we at this point? You now have a completely functional ODEE installation, from soup to nuts as they say. You can further expand your installation by doing some of the following activities: clustering WebLogic services configuring WebLogic for redundancy configuring Oracle 11g for RAC adding additional Factory servers for redundancy/processing capacity setting up a real MRL (instead of the sample resources) testing Documaker Web Services for job submission and more! I certainly hope you've enjoyed this and find it useful. If you find yourself running into trouble, visit the Oracle Community for Documaker - there is plenty of activity there and you can ask questions. For more concentrated assistance, you can engage an Oracle consultant who is a subject matter expert to assist you. Feel free to email me [andy (dot) little (at) oracle (dot) com] and I can connect you with the appropriate resource to get started. Best of luck! -Andy

SQL SERVER – A Quick Look at Logging and Ideas around Logging

- by pinaldave

This blog post is written in response to the T-SQL Tuesday post on Logging. When someone talks about logging, personally I get lots of ideas about it. I have seen logging as a very generic term. Let me ask you this question first before I continue writing about logging. What is the first thing comes to your mind when you hear word “Logging”? Now ask the same question to the guy standing next to you. I am pretty confident that you will get a different answer from different people. I decided to do this activity and asked 5 SQL Server person the same question. Question: What is the first thing comes to your mind when you hear the word “Logging”? Strange enough I got a different answer every single time. Let me just list what answer I got from my friends. Let us go over them one by one. Output Clause The very first person replied output clause. Pretty interesting answer to start with. I see what exactly he was thinking. SQL Server 2005 has introduced a new OUTPUT clause. OUTPUT clause has access to inserted and deleted tables (virtual tables) just like triggers. OUTPUT clause can be used to return values to client clause. OUTPUT clause can be used with INSERT, UPDATE, or DELETE to identify the actual rows affected by these statements. Here are some references for Output Clause: OUTPUT Clause Example and Explanation with INSERT, UPDATE, DELETE Reasons for Using Output Clause – Quiz Tips from the SQL Joes 2 Pros Development Series – Output Clause in Simple Examples Error Logs I was expecting someone to mention Error logs when it is about logging. The error log is the most looked place when there is any error either with the application or there is an error with the operating system. I have kept the policy to check my server’s error log every day. The reason is simple – enough time in my career I have figured out that when I am looking at error logs I find something which I was not expecting. There are cases, when I noticed errors in the error log and I fixed them before end user notices it. Other common practices I always tell my DBA friends to do is that when any error happens they should find relevant entries in the error logs and document the same. It is quite possible that they will see the same error in the error log and able to fix the error based on the knowledge base which they have created. There can be many different kinds of error log files exists in SQL Server as well – 1) SQL Server Error Logs 2) Windows Event Log 3) SQL Server Agent Log 4) SQL Server Profile Log 5) SQL Server Setup Log etc. Here are some references for Error Logs: Recycle Error Log – Create New Log file without Server Restart SQL Error Messages Change Data Capture I got surprised with this answer. I think more than the answer I was surprised by the person who had answered me this one. I always thought he was expert in HTML, JavaScript but I guess, one should never assume about others. Indeed one of the cool logging feature is Change Data Capture. Change Data Capture records INSERTs, UPDATEs, and DELETEs applied to SQL Server tables, and makes a record available of what changed, where, and when, in simple relational ‘change tables’ rather than in an esoteric chopped salad of XML. These change tables contain columns that reflect the column structure of the source table you have chosen to track, along with the metadata needed to understand the changes that have been made. Here are some references for Change Data Capture: Introduction to Change Data Capture (CDC) in SQL Server 2008 Tuning the Performance of Change Data Capture in SQL Server 2008 Download Script of Change Data Capture (CDC) CDC and TRUNCATE – Cannot truncate table because it is published for replication or enabled for Change Data Capture Dynamic Management View (DMV) I like this answer. If asked I would have not come up with DMV right away but in the spirit of the original question, I think DMV does log the data. DMV logs or stores or records the various data and activity on the SQL Server. Dynamic management views return server state information that can be used to monitor the health of a server instance, diagnose problems, and tune performance. One can get plethero of information from DMVs – High Availability Status, Query Executions Details, SQL Server Resources Status etc. Here are some references for Dynamic Management View (DMV): SQL SERVER – Denali – DMV Enhancement – sys.dm_exec_query_stats – New Columns DMV – sys.dm_os_windows_info – Information about Operating System DMV – sys.dm_os_wait_stats Explanation – Wait Type – Day 3 of 28 DMV sys.dm_exec_describe_first_result_set_for_object – Describes the First Result Metadata for the Module Transaction Log Impact Detection Using DMV – dm_tran_database_transactions Log Files I almost flipped with this final answer from my friend. This should be probably the first answer. Yes, indeed log file logs the SQL Server activities. One can write infinite things about log file. SQL Server uses log file with the extension .ldf to manage transactions and maintain database integrity. Log file ensures that valid data is written out to database and system is in a consistent state. Log files are extremely useful in case of the database failures as with the help of full backup file database can be brought in the desired state (point in time recovery is also possible). SQL Server database has three recovery models – 1) Simple, 2) Full and 3) Bulk Logged. Each of the model uses the .ldf file for performing various activities. It is very important to take the backup of the log files (along with full backup) as one never knows when backup of the log file come into the action and save the day! How to Stop Growing Log File Too Big Reduce the Virtual Log Files (VLFs) from LDF file Log File Growing for Model Database – model Database Log File Grew Too Big master Database Log File Grew Too Big SHRINKFILE and TRUNCATE Log File in SQL Server 2008 Can I just say I loved this month’s T-SQL Tuesday Question. It really provoked very interesting conversation around me.

A simple Dynamic Proxy

- by Abhijeet Patel

Frameworks such as EF4 and MOQ do what most developers consider "dark magic". For instance in EF4, when you use a POCO for an entity you can opt-in to get behaviors such as "lazy-loading" and "change tracking" at runtime merely by ensuring that your type has the following characteristics: The class must be public and not sealed. The class must have a public or protected parameter-less constructor. The class must have public or protected properties Adhere to this and your type is magically endowed with these behaviors without any additional programming on your part. Behind the scenes the framework subclasses your type at runtime and creates a "dynamic proxy" which has these additional behaviors and when you navigate properties of your POCO, the framework replaces the POCO type with derived type instances. The MOQ framework does simlar magic. Let's say you have a simple interface: public interface IFoo { int GetNum(); } We can verify that the GetNum() was invoked on a mock like so: var mock = new Mock<IFoo>(MockBehavior.Default); mock.Setup(f => f.GetNum()); var num = mock.Object.GetNum(); mock.Verify(f => f.GetNum()); Beind the scenes the MOQ framework is generating a dynamic proxy by implementing IFoo at runtime. the call to moq.Object returns the dynamic proxy on which we then call "GetNum" and then verify that this method was invoked. No dark magic at all, just clever programming is what's going on here, just not visible and hence appears magical! Let's create a simple dynamic proxy generator which accepts an interface type and dynamically creates a proxy implementing the interface type specified at runtime. public static class DynamicProxyGenerator { public static T GetInstanceFor<T>() { Type typeOfT = typeof(T); var methodInfos = typeOfT.GetMethods(); AssemblyName assName = new AssemblyName("testAssembly"); var assBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(assName, AssemblyBuilderAccess.RunAndSave); var moduleBuilder = assBuilder.DefineDynamicModule("testModule", "test.dll"); var typeBuilder = moduleBuilder.DefineType(typeOfT.Name + "Proxy", TypeAttributes.Public); typeBuilder.AddInterfaceImplementation(typeOfT); var ctorBuilder = typeBuilder.DefineConstructor( MethodAttributes.Public, CallingConventions.Standard, new Type[] { }); var ilGenerator = ctorBuilder.GetILGenerator(); ilGenerator.EmitWriteLine("Creating Proxy instance"); ilGenerator.Emit(OpCodes.Ret); foreach (var methodInfo in methodInfos) { var methodBuilder = typeBuilder.DefineMethod( methodInfo.Name, MethodAttributes.Public | MethodAttributes.Virtual, methodInfo.ReturnType, methodInfo.GetParameters().Select(p => p.GetType()).ToArray() ); var methodILGen = methodBuilder.GetILGenerator(); methodILGen.EmitWriteLine("I'm a proxy"); if (methodInfo.ReturnType == typeof(void)) { methodILGen.Emit(OpCodes.Ret); } else { if (methodInfo.ReturnType.IsValueType || methodInfo.ReturnType.IsEnum) { MethodInfo getMethod = typeof(Activator).GetMethod(/span>"CreateInstance",new Type[]{typeof((Type)}); LocalBuilder lb = methodILGen.DeclareLocal(methodInfo.ReturnType); methodILGen.Emit(OpCodes.Ldtoken, lb.LocalType); methodILGen.Emit(OpCodes.Call, typeofype).GetMethod("GetTypeFromHandle")); )); methodILGen.Emit(OpCodes.Callvirt, getMethod); methodILGen.Emit(OpCodes.Unbox_Any, lb.LocalType); } else { methodILGen.Emit(OpCodes.Ldnull); } methodILGen.Emit(OpCodes.Ret); } typeBuilder.DefineMethodOverride(methodBuilder, methodInfo); } Type constructedType = typeBuilder.CreateType(); var instance = Activator.CreateInstance(constructedType); return (T)instance; } } Dynamic proxies are created by calling into the following main types: AssemblyBuilder, TypeBuilder, Modulebuilder and ILGenerator. These types enable dynamically creating an assembly and emitting .NET modules and types in that assembly, all using IL instructions. Let's break down the code above a bit and examine it piece by piece Type typeOfT = typeof(T); var methodInfos = typeOfT.GetMethods(); AssemblyName assName = new AssemblyName("testAssembly"); var assBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(assName, AssemblyBuilderAccess.RunAndSave); var moduleBuilder = assBuilder.DefineDynamicModule("testModule", "test.dll"); var typeBuilder = moduleBuilder.DefineType(typeOfT.Name + "Proxy", TypeAttributes.Public); We are instructing the runtime to create an assembly caled "test.dll"and in this assembly we then emit a new module called "testModule". We then emit a new type definition of name "typeName"Proxy into this new module. This is the definition for the "dynamic proxy" for type T typeBuilder.AddInterfaceImplementation(typeOfT); var ctorBuilder = typeBuilder.DefineConstructor( MethodAttributes.Public, CallingConventions.Standard, new Type[] { }); var ilGenerator = ctorBuilder.GetILGenerator(); ilGenerator.EmitWriteLine("Creating Proxy instance"); ilGenerator.Emit(OpCodes.Ret); The newly created type implements type T and defines a default parameterless constructor in which we emit a call to Console.WriteLine. This call is not necessary but we do this so that we can see first hand that when the proxy is constructed, when our default constructor is invoked. var methodBuilder = typeBuilder.DefineMethod( methodInfo.Name, MethodAttributes.Public | MethodAttributes.Virtual, methodInfo.ReturnType, methodInfo.GetParameters().Select(p => p.GetType()).ToArray() ); We then iterate over each method declared on type T and add a method definition of the same name into our "dynamic proxy" definition if (methodInfo.ReturnType == typeof(void)) { methodILGen.Emit(OpCodes.Ret); } If the return type specified in the method declaration of T is void we simply return. if (methodInfo.ReturnType.IsValueType || methodInfo.ReturnType.IsEnum) { MethodInfo getMethod = typeof(Activator).GetMethod("CreateInstance", new Type[]{typeof(Type)}); LocalBuilder lb = methodILGen.DeclareLocal(methodInfo.ReturnType); methodILGen.Emit(OpCodes.Ldtoken, lb.LocalType); methodILGen.Emit(OpCodes.Call, typeof(Type).GetMethod("GetTypeFromHandle")); methodILGen.Emit(OpCodes.Callvirt, getMethod); methodILGen.Emit(OpCodes.Unbox_Any, lb.LocalType); } If the return type in the method declaration of T is either a value type or an enum, then we need to create an instance of the value type and return that instance the caller. In order to accomplish that we need to do the following: 1) Get a handle to the Activator.CreateInstance method 2) Declare a local variable which represents the Type of the return type(i.e the type object of the return type) specified on the method declaration of T(obtained from the MethodInfo) and push this Type object onto the evaluation stack. In reality a RuntimeTypeHandle is what is pushed onto the stack. 3) Invoke the "GetTypeFromHandle" method(a static method in the Type class) passing in the RuntimeTypeHandle pushed onto the stack previously as an argument, the result of this invocation is a Type object (representing the method's return type) which is pushed onto the top of the evaluation stack. 4) Invoke Activator.CreateInstance passing in the Type object from step 3, the result of this invocation is an instance of the value type boxed as a reference type and pushed onto the top of the evaluation stack. 5) Unbox the result and place it into the local variable of the return type defined in step 2 methodILGen.Emit(OpCodes.Ldnull); If the return type is a reference type then we just load a null onto the evaluation stack methodILGen.Emit(OpCodes.Ret); Emit a a return statement to return whatever is on top of the evaluation stack(null or an instance of a value type) back to the caller Type constructedType = typeBuilder.CreateType(); var instance = Activator.CreateInstance(constructedType); return (T)instance; Now that we have a definition of the "dynamic proxy" implementing all the methods declared on T, we can now create an instance of the proxy type and return that out typed as T. The caller can now invoke the generator and request a dynamic proxy for any type T. In our example when the client invokes GetNum() we get back "0". Lets add a new method on the interface called DayOfWeek GetDay() public interface IFoo { int GetNum(); DayOfWeek GetDay(); } When GetDay() is invoked, the "dynamic proxy" returns "Sunday" since that is the default value for the DayOfWeek enum This is a very trivial example of dynammic proxies, frameworks like MOQ have a way more sophisticated implementation of this paradigm where in you can instruct the framework to create proxies which return specified values for a method implementation.

The JavaScript shown below can be used with an af:clientListener tag on af:inputListOfValues or af:inputDate. At runtime, the JavaScript code determines the component type it is executed on and either opens the LOV dialog or the input Date popup. <af:resource type="javascript"> /** * function to launch dialog if cursor is in LOV or * input date field * @param evt argument to capture the AdfUIInputEvent object */ function launchPopUpUsingF8(evt) { var component = evt.getSource(); if (evt.getKeyCode() == AdfKeyStroke.F8_KEY) { //check for input LOV component if (component.getTypeName() == 'AdfRichInputListOfValues') { AdfLaunchPopupEvent.queue(component, true); //event is handled on the client. Server does not need //to be notified evt.cancel(); } //check for input Date component else if (component.getTypeName() == 'AdfRichInputDate') { //the inputDate af:popup component ID always is ::pop var popupClientId = component.getAbsoluteLocator() + '::pop'; var popup = component.findComponent(popupClientId); var hints = {align : AdfRichPopup.ALIGN_END_AFTER, alignId : component.getAbsoluteLocator()}; popup.show(hints); //event is handled on the client. Server does not need //to be notified evt.cancel(); } } } </af:resource> The af:clientListener that calls the JavaScript is added as shown below. <af:inputDate label="Label 1" id="id1"> <af:clientListener method="launchPopUpUsingF8" type="keyDown"/> </af:inputDate> As you may have noticed, the call to open the popup is different for the af:inputListOfValues and the af:inputDate. For the list of values component, an ADF Faces AdfLaunchPopupEvent is queued with the LOV component passed s an argument. Launching the input date popup is a bit more complicate and requires you to lookup the implicit popup dialog and to open it manually. Because the popup is opened manually using the show() method on the af:popup component, the alignment of the dialog also needs to be handled manually. For this, the popup component specifies alignment hints, that for the ALIGN_END_AFTER hint aligns the dialog at the end and below the date component. The align Id hint specifies the component the dialog is relatively positioned to, which of course should be the input date field. The ADF Faces JavaScript API and how to use it is further explained in the Using JavaScript in ADF Faces Rich Client Applications whitepaper available from the Oracle Technology Network (OTN) http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf An ADF Insider recording about JavaScript in ADF Faces can be watched from here http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/adf-insider-javascript/adf-insider-javascript.html

Generate Strongly Typed Observable Events for the Reactive Extensions for .NET (Rx)

- by Bobby Diaz

I must have tried reading through the various explanations and introductions to the new Reactive Extensions for .NET before the concepts finally started sinking in. The article that gave me the ah-ha moment was over on SilverlightShow.net and titled Using Reactive Extensions in Silverlight. The author did a good job comparing the "normal" way of handling events vs. the new "reactive" methods. Admittedly, I still have more to learn about the Rx Framework, but I wanted to put together a sample project so I could start playing with the new Observable and IObservable<T> constructs. I decided to throw together a whiteboard application in Silverlight based on the Drawing with Rx example on the aforementioned article. At the very least, I figured I would learn a thing or two about a new technology, but my real goal is to create a fun application that I can share with the kids since they love drawing and coloring so much! Here is the code sample that I borrowed from the article: var mouseMoveEvent = Observable.FromEvent<MouseEventArgs>(this, "MouseMove"); var mouseLeftButtonDown = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonDown"); var mouseLeftButtonUp = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonUp"); var draggingEvents = from pos in mouseMoveEvent .SkipUntil(mouseLeftButtonDown) .TakeUntil(mouseLeftButtonUp) .Let(mm => mm.Zip(mm.Skip(1), (prev, cur) => new { X2 = cur.EventArgs.GetPosition(this).X, X1 = prev.EventArgs.GetPosition(this).X, Y2 = cur.EventArgs.GetPosition(this).Y, Y1 = prev.EventArgs.GetPosition(this).Y })).Repeat() select pos; draggingEvents.Subscribe(p => { Line line = new Line(); line.Stroke = new SolidColorBrush(Colors.Black); line.StrokeEndLineCap = PenLineCap.Round; line.StrokeLineJoin = PenLineJoin.Round; line.StrokeThickness = 5; line.X1 = p.X1; line.Y1 = p.Y1; line.X2 = p.X2; line.Y2 = p.Y2; this.LayoutRoot.Children.Add(line); }); One thing that was nagging at the back of my mind was having to deal with the event names as strings, as well as the verbose syntax for the Observable.FromEvent<TEventArgs>() method. I came up with a couple of static/helper classes to resolve both issues and also created a T4 template to auto-generate these helpers for any .NET type. Take the following code from the above example: var mouseMoveEvent = Observable.FromEvent<MouseEventArgs>(this, "MouseMove"); var mouseLeftButtonDown = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonDown"); var mouseLeftButtonUp = Observable.FromEvent<MouseButtonEventArgs>(this, "MouseLeftButtonUp"); Turns into this with the new static Events class: var mouseMoveEvent = Events.Mouse.Move.On(this); var mouseLeftButtonDown = Events.Mouse.LeftButtonDown.On(this); var mouseLeftButtonUp = Events.Mouse.LeftButtonUp.On(this); Or better yet, just remove the variable declarations altogether: var draggingEvents = from pos in Events.Mouse.Move.On(this) .SkipUntil(Events.Mouse.LeftButtonDown.On(this)) .TakeUntil(Events.Mouse.LeftButtonUp.On(this)) .Let(mm => mm.Zip(mm.Skip(1), (prev, cur) => new { X2 = cur.EventArgs.GetPosition(this).X, X1 = prev.EventArgs.GetPosition(this).X, Y2 = cur.EventArgs.GetPosition(this).Y, Y1 = prev.EventArgs.GetPosition(this).Y })).Repeat() select pos; The Move, LeftButtonDown and LeftButtonUp members of the Events.Mouse class are readonly instances of the ObservableEvent<TTarget, TEventArgs> class that provide type-safe access to the events via the On() method. Here is the code for the class: using System; using System.Collections.Generic; using System.Linq; namespace System.Linq { /// <summary> /// Represents an event that can be managed via the <see cref="Observable"/> API. /// </summary> /// <typeparam name="TTarget">The type of the target.</typeparam> /// <typeparam name="TEventArgs">The type of the event args.</typeparam> public class ObservableEvent<TTarget, TEventArgs> where TEventArgs : EventArgs { /// <summary> /// Initializes a new instance of the <see cref="ObservableEvent"/> class. /// </summary> /// <param name="eventName">Name of the event.</param> protected ObservableEvent(String eventName) { EventName = eventName; } /// <summary> /// Registers the specified event name. /// </summary> /// <param name="eventName">Name of the event.</param> /// <returns></returns> public static ObservableEvent<TTarget, TEventArgs> Register(String eventName) { return new ObservableEvent<TTarget, TEventArgs>(eventName); } /// <summary> /// Creates an enumerable sequence of event values for the specified target. /// </summary> /// <param name="target">The target.</param> /// <returns></returns> public IObservable<IEvent<TEventArgs>> On(TTarget target) { return Observable.FromEvent<TEventArgs>(target, EventName); } /// <summary> /// Gets or sets the name of the event. /// </summary> /// <value>The name of the event.</value> public string EventName { get; private set; } } } And this is how it's used: /// <summary> /// Categorizes <see cref="ObservableEvents"/> by class and/or functionality. /// </summary> public static partial class Events { /// <summary> /// Implements a set of predefined <see cref="ObservableEvent"/>s /// for the <see cref="System.Windows.System.Windows.UIElement"/> class /// that represent mouse related events. /// </summary> public static partial class Mouse { /// <summary>Represents the MouseMove event.</summary> public static readonly ObservableEvent<UIElement, MouseEventArgs> Move = ObservableEvent<UIElement, MouseEventArgs>.Register("MouseMove"); // additional members omitted... } } The source code contains a static Events class with prefedined members for various categories (Key, Mouse, etc.). There is also an Events.tt template that you can customize to generate additional event categories for any .NET type. All you should have to do is add the name of your class to the types collection near the top of the template: types = new Dictionary<String, Type>() { //{ "Microsoft.Maps.MapControl.Map, Microsoft.Maps.MapControl", null } { "System.Windows.FrameworkElement, System.Windows", null }, { "Whiteboard.MainPage, Whiteboard", null } }; The template is also a bit rough at this point, but at least it generates code that *should* compile. Please let me know if you run into any issues with it. Some people have reported errors when trying to use T4 templates within a Silverlight project, but I was able to get it to work with a little black magic... You can download the source code for this project or play around with the live demo. Just be warned that it is at a very early stage so don't expect to find much today. I plan on adding alot more options like pen colors and sizes, saving, printing, etc. as time permits. HINT: hold down the ESC key to erase! Enjoy!

We have the following hardware: Sun Blade X6270 2* LSISAS1068E SAS controllers 2* Sun J4400 JBODs with 1 TB disks (24 disks per JBOD) Fedora Core 12 2.6.33 release kernel from FC13 (also tried with latest 2.6.31 kernel from FC12, same results) Here's the datasheet for the SAS hardware: http://www.sun.com/storage/storage_networking/hba/sas/PCIe.pdf It's using PCI Express 1.0a, 8x lanes. With a bandwidth of 250 MB/sec per lane, we should be able to do 2000 MB/sec per SAS controller. Each controller can do 3 Gb/sec per port and has two 4 port PHYs. We connect both PHYs from a controller to a JBOD. So between the JBOD and the controller we have 2 PHYs * 4 SAS ports * 3 Gb/sec = 24 Gb/sec of bandwidth, which is more than the PCI Express bandwidth. With write caching enabled and when doing big writes, each disk can sustain about 80 MB/sec (near the start of the disk). With 24 disks, that means we should be able to do 1920 MB/sec per JBOD. multipath { rr_min_io 100 uid 0 path_grouping_policy multibus failback manual path_selector "round-robin 0" rr_weight priorities alias somealias no_path_retry queue mode 0644 gid 0 wwid somewwid } I tried values of 50, 100, 1000 for rr_min_io, but it doesn't seem to make much difference. Along with varying rr_min_io I tried adding some delay between starting the dd's to prevent all of them writing over the same PHY at the same time, but this didn't make any difference, so I think the I/O's are getting properly spread out. According to /proc/interrupts, the SAS controllers are using a "IR-IO-APIC-fasteoi" interrupt scheme. For some reason only core #0 in the machine is handling these interrupts. I can improve performance slightly by assigning a separate core to handle the interrupts for each SAS controller: echo 2 /proc/irq/24/smp_affinity echo 4 /proc/irq/26/smp_affinity Using dd to write to the disk generates "Function call interrupts" (no idea what these are), which are handled by core #4, so I keep other processes off this core too. I run 48 dd's (one for each disk), assigning them to cores not dealing with interrupts like so: taskset -c somecore dd if=/dev/zero of=/dev/mapper/mpathx oflag=direct bs=128M oflag=direct prevents any kind of buffer cache from getting involved. None of my cores seem maxed out. The cores dealing with interrupts are mostly idle and all the other cores are waiting on I/O as one would expect.

Given the math above I would expect something in the range of 2*1920 ~= 3600+ MB/sec. Does anybody have any idea where my missing bandwidth went? Thanks!
