How to deploy jBPM 3.2.2 console on Oracle 10g iAS

- by Balint Pato

Hi! Does anybody have experience regarding deployment of the jBPM Administration Console on Oracle 10g iAS? I successfully deployed it using an .ear, security mappings working, I can even login to the console, Hibernate finds the JNDI datasource but it cannot find the TransactionManager. I see no log, only the exception thrown in the jsf page: Can anybody help me? The hibernate.cfg.xml file now looks like this: <?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

NServiceBus Generic Host and mqsvc.exe high CPU

- by Michael Stephenson

We have been doing some work with NServiceBus recently and observed some unusual behaviour which was caused by our mistake and seemed worthy of a small post. The Scenario In our solution we were doing some standard NServiceBus stuff by pushing a message to a queue using NServiceBus. We had a direct send/receive scenario rather than a publish/subscribe one. The background process which was meant to collect the message and then process it was a normal NServiceBus message handler. We would run the NServiceBus.Host.exe which would find the handler and then do the usual NServiceBus magic. The Problem In this solution we were creating some automated tests around this module of the integration process to ensure that it would work well. We had two tests. Test 1 This test would start NServiceBus.Host.exe using the Process object, then seed a message to the queue via our web service façade sitting above the queue which wrapped NServiceBus. The background process would then process the message and the test would check the message had been processed fine. If all was well then the NServiceBus.Host.exe process was stopped. Test 2 In test 2 we would do a very similar thing except that instead of starting the process the test would install NServiceBus.Host.exe as a windows service and then start the service before the test and once the test was executed it would stop the test. The Results of the Tests Test 1 worked really well, however in test 2 we found that it didn’t really work at all, instead of doing the background process we were finding that between mqsvc.exe and NServiceBus.Host.exe the CPU on the machine was maxed and nothing was really happening. The Solution After trying a few things we found it was the permissions on the queue were not set correctly. Once this was resolved it all worked fine and CPU was not excessive and ran just like the console application. I think the couple of take aways from this are: Make sure you set the windows service for NserviceBus Generic Host to the right credentials When you install the generic host as a windows service then by default it will use the default windows credentials. For any production like scenario you should be using a domain account to run the process as via the windows service. Make sure you have the queue set with the right permissions For the credentials you have used to configure the generic host as a windows service you should ensure that this user has the appropriate permissions for any queues it will interact with. Make sure you turn on the right logging configuration in NServiceBus When this wasnt working correctly we didnt know there was an issue, we were just experiencing the high CPU condition. I am a little surprised that there wasnt something logged and that the process didnt crash. I guess this could be by design bearing in mind that the process could be monitoring many queues. In this point Im just saying that originally we didnt have all of the log4net logging which is available from NServiceBus turned on. Its probably a good idea to have this turned on and configured until you are happy your solution is working fine. Thanks to Ahmed Hashmi on my team who got this working in the end.

Extended Logging with Caller Info Attributes

- by João Angelo

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

NHibernate.Bytecode.UnableToLoadProxyFactoryFactoryException

I have the following code set up in my Startup IDictionary properties = new Dictionary(); properties.Add("connection.driver_class", "NHibernate.Driver.SqlClientDriver"); properties.Add("dialect", "NHibernate.Dialect.MsSql2005Dialect"); properties.Add("proxyfactory.factory_class", "NNHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle"); properties.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider"); properties.Add("connection.connection_string", "Data Source=ZEUS;Initial Catalog=mydb;Persist Security Info=True;User ID=sa;Password=xxxxxxxx"); InPlaceConfigurationSource source = new InPlaceConfigurationSource(); source.Add(typeof(ActiveRecordBase), (IDictionary<string, string>) properties); Assembly asm = Assembly.Load("Repository"); Castle.ActiveRecord.ActiveRecordStarter.Initialize(asm, source); I am getting the following error: failed: NHibernate.Bytecode.UnableToLoadProxyFactoryFactoryException : Unable to load type 'NNHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle' during configuration of proxy factory class. Possible causes are: - The NHibernate.Bytecode provider assembly was not deployed. - The typeName used to initialize the 'proxyfactory.factory_class' property of the session-factory section is not well formed. I have read and read I am referecning the All the assemblies listed and I am at a total loss as what to try next. Castle.ActiveRecord.dll Castle.DynamicProxy2.dll Iesi.Collections.dll log4net.dll NHibernate.dll NHibernate.ByteCode.Castle.dll I am 100% sure the assembly is in the bin. Anyone have any ideas?

Problem in Apache CXF (Simple Frontend): 'Already connected'

- by seanizer

I am using apache CXF for the first time. I am trying to establish a connection based on the CXF simple front end (Configuration notes) technology. I can't really see what I've done wrong, but I am getting a weird error (see below). I have also posted this question to [email protected], but I haven't received a response yet. Perhaps someone here can help. The service bean that is wrapped here is a Spring / JPA service that does not know anything about the web, I want to use simple frontend to publish it as a web service without having to annotate it with Jax-ws etc. (This works in theory).

I am trying to use the simple frontend, as my service is not annotated with jax-ws annotations and I would like to keep it that way. Can someone help? Thanks in advance. Sean

ASP.NET MVC 2 with NServiceBus unable to load requested types

- by dp

I am trying to use NServiceBus with an ASP.NET MVC 2 website (using VS 2010 and the .NET 4.0 framework). However, when I run the site on my local machine, I get the following error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. Here are the relevant steps I have taken: Downloaded the NServiceBus.2.0.0.1145 binaries In my asp.net mvc app, I've added references to NServiceBus.dll and NServiceBus.Core.dll In Global.asax.cs I've added: public static IBus Bus { get; private set; } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); Bus = NServiceBus.Configure .WithWeb() .Log4Net() .DefaultBuilder() .XmlSerializer() .MsmqTransport() .IsTransactional(false) .PurgeOnStartup(false) .UnicastBus() .ImpersonateSender(false) .CreateBus() .Start(); } In web.config, I've added: <MsmqTransportConfig InputQueue="MyWebClient" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5"/> <UnicastBusConfig> <MessageEndpointMappings> <add Messages="Messages" Endpoint="MyServerInputQueue"/> </MessageEndpointMappings> </UnicastBusConfig> The error indicates that the problem is with the first line in the Global.asax.cs file. Is it possible that there is a problem with NServiceBus running under .NET 4.0?

How to use InterfaceInterceptor with NServiceBus UnityBuilder

- by David

I have a MessageHandler with a dependency declared as: public IRepository<Person> PersonRepository {get;set;} I set up my Unity container with: IUnityContainer container = new UnityContainer(); container.AddNewExtension<Interception>(); container.RegisterType(typeof(IRepository<Person>), typeof(Example.Data.InMemory.Repository<Person>)); container.Configure<Interception>() .AddPolicy("PersonAddAdvice") .AddMatchingRule(new AddMatchingRule()) .AddCallHandler(new PersonAddedEventPublishingCallHandler()); container.Configure<Interception>() .SetInterceptorFor<IRepository<Person>>(new InterfaceInterceptor()); Then I Init my endpoint with: class EndpointConfig : IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .Log4Net() .UnityBuilder(ContainerConfig.LoadContainer()) .XmlSerializer(); } } (ContainerConfig.LoadContainer() returns the pre-configured IUnityContainer) the problem is that the IRepository dependency in my MessageHandler is not resolved (it's null when handling the messages). If I remove the interception configuration from the Unity container, and simply do this: IUnityContainer container = new UnityContainer(); container.RegisterType(typeof(IRepository<Person>), typeof(Example.Data.InMemory.Repository<Person>)); It works as expected, and the MessageHandler has an instance if IRepository resolved.

Troubleshooting ASP .NET Application on Shared Hosting

- by James

Hi, My company has a CRM site hosted externally on a shared server and recently it has been very problematic. Users are being logged out randomly, sometimes only seconds after logging in. We are also getting viewstate validation errors at times. Both problems seem to occur more often when there are two or more people logged in at the same time, but I can't really see any particular pattern. I am using log4net to track the application state and from what I can tell it seems that the application is frequently restarting, causing all sorts of issues. I can see log messages from the Application_Start event handler but there is not always a corresponding message from the Application_End event handler. There is also logging code in the Application_Error event handler but it is not catching anything at the time of the restart. These errors started to occur soon after we moved our site to this shared server, although I don't remember it being this bad at first. Any advice on how to track down these problems would be appreciated. The server is running Windows Server 2003 and IIS 6.0. Sadly I don't have access to the server other than through Parallels Plesk and it doesn't seem to have any useful diagnostic information.

Global.asax parser errors when deploying MVC 1 application to remote server.

- by mannish

So we're having some issues deploying an ASP.NET MVC app to a client site. Basically when we try to test the app from localhost, we get the dreaded Global.asax parser error indicating it could not load the application global. Research indicates there are basically 4 possible reasons for this exception we're seeing: The solution hasn't been built. This clearly isn't the case since we can deploy it here and it runs fine on any machine we deploy to AND we had to build and publish the darn thing to deploy it anyway. The Global.asax namespace inheritance does not match the application global code file. Again we double checked this and since it runs just fine here that can't be the issue. Miscellaneous non-descript IIS/VS.NET mischief. Basically something get's wonky in IIS or VS.NET and the web server won't behave correctly for this application. We've done cleans and rebuilds, we've deleted virtual dir and recreated, and performed all of the IIS munging that we've found elsewhere online. Various combinations of IIS bounces, server reboots, virtual dir/application recreation, etc. Code level permissions issue. We've verified full trust in machine/web config in the framework directory, we've set .NET trust to full in IIS, we've granted Everyone full control on the directories just to hit it with the security hammer, etc. etc. The pertinent detials: Windows Server 2008 x64 IIS 7, 32 bit compatible app pool (app was written on 32 bit OS compiled for any cpu) App pool identity set to NetworkService Microsoft ASP.NET MVC 1.0 XCopy deployment We deployed another read-only app just fine. The significant difference in this app is the use of NHibernate and Log4Net which require full trust. Additionally, the actual project name of the web project differs from the default namespace however the Inherits namespace in Global.asax and the Global.asax.cs files match so this shouldn't be an issue. Anybody have any bright ideas? We're officially down to just the dim ones.

Messages not forwarded to error queue when exception is thrown in handler (it works on my machine)

- by darthjit

e are using NServicebus 4.0.5 with sql server(sql server 2012) as transport. When the handler throws an exception, NSB does not retry or move the message to the error queue. Successful messages make it to the audit queue but the failed/errored ones don't! . Interestingly, all this works on our local machines(windows 7 ,sql server localdb) but not on windows server 2012 (sql server 2012). Here is the config info on the subscriber: <add name="NServiceBus/Transport" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <add name="NServiceBus/Persistence" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <MessageForwardingInCaseOfFaultConfig ErrorQueue="error" /> <UnicastBusConfig ForwardReceivedMessagesTo="audit"> <MessageEndpointMappings> <add Assembly="Services.Section.Messages" Endpoint= "Services.ACL.Worker" /> </MessageEndpointMappings> </UnicastBusConfig> And in code it is configured as follows: public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization { public void Init() { IContainer container = ContainerInstanceProvider. GetContainerInstance(); Configure .Transactions.Enable(); Configure.With() .AutofacBuilder(container) .UseTransport<SqlServer>() .Log4Net() //.Serialization.Json() .UseNHibernateSubscriptionPersister() .UseNHibernateTimeoutPersister() .MessageForwardingInCaseOfFault() .RijndaelEncryptionService() .DefiningCommandsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Commands")) .DefiningEventsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Events")) .UnicastBus(); } } Any ideas on how to fix this? here is the log info (there is a lot there, search for error to see the relevant parts) https://gist.github.com/ranji/7378249

Improve Log Exceptions

- by Jaider

I am planning to use log4net in a new web project. In my experience, I see how big the log table can get, also I notice that errors or exceptions are repeated. For instance, I just query a log table that have more than 132.000 records, and I using distinct and found that only 2.500 records are unique (~2%), the others (~98%) are just duplicates. so, I came up with this idea to improve logging. Having a couple of new columns: counter and updated_dt, that are updated every time try to insert same record. If want to track the user that cause the exception, need to create a user_log or log_user table, to map N-N relationship. Create this model may made the system slow and inefficient trying to compare all these long text... Here the trick, we should also has a hash column of binary of 16 or 32, that hash the message and the exception, and configure an index on it. We can use HASHBYTES to help us. I am not an expert in DB, but I think that will made the faster way to locate a similar record. And because hashing doesn't guarantee uniqueness, will help to locale those similar record much faster and later compare by message or exception directly to make sure that are unique. This is a theoretical/practical solution, but will it work or bring more complexity? what aspects I am leaving out or what other considerations need to have? the trigger will do the job of insert or update, but is the trigger the best way to do it?

ASP.Net MVC DotNetOpenAuth Sample Issue on publish

- by Roger D. Pharr

I'm trying to use the MSDN Open ID project template for ASP.NET MVC C#. I've been able to configure a local copy to run well. But when I publish it to my hosting provider - it craps out. The error is "500 internal server error". Is there something I should know about publishing this template that I haven't noticed? Here are some more details (for diligence): Hosting provider is GoDaddy/SQL2005/IIS7. When I configure & publish the blank MVC template, it works. The local database publishes successfully, but I haven't been able to troubleshoot the connection in web.config yet. I expect there are connection string problems in the file. I tried disabling all of the references to log4net, as it seemed to be invoked several times on startup. But those changes did not seem to make a difference in either the local or published application performance. My IDE is Visual Studio 2010 Pro Any help would be greatly appreciated!

NHibernate will not insert a record

- by Brian Beckham

I have an application that is now 4+ years old that is exhibiting some odd behavior on our latest deployment. The application uses nHibernate for all inserts / updates / selects, etc. We are currently using .NET 2.0, and nHibernate 1.2 (I know, we need to upgrade) This deployment is on Windows 2008 Server x64, IIS 7.5 - what I have seen so far is that the application runs, but is unable to insert or update records in the DB - reads seem fine so far, but writes are a problem. SOME writes actually work, inserts into some small tables, but most never even make it to the DB. Using SQL Profiler, the insert / updates never make it to the server, and turning log4net up to DEBUG, and show_sql true - the select statements appear, but the insert / update statements never make it into the log at all, and never show up at the server. What's even more odd is that the application seems to be oblivious to this - the commandandclose runs without exception (open session in view with an httpmodule), the domain objects come back with uuid's generated, etc. but never get persisted. Certainly an upgrade is due, but I would hate to try it during a deployment, and without time to accurately test the app. Any ideas?

NHibernate + Fluent long startup time

- by PaRa

Hi all, am new to NHibernate. When performing below test took 11.2 seconds (debug mode) i am seeing this large startup time in all my tests (basically creating the first session takes a tone of time) setup = Windows 2003 SP2 / Oracle10gR2 latest CPU / ODP.net 2.111.7.20 / FNH 1.0.0.636 / NHibernate 2.1.2.4000 / NUnit 2.5.2.9222 / VS2008 SP1 using System; using System.Collections; using System.Data; using System.Globalization; using System.IO; using System.Text; using System.Data; using NUnit.Framework; using System.Collections.Generic; using System.Data.Common; using NHibernate; using log4net.Config; using System.Configuration; using FluentNHibernate; [Test()] public void GetEmailById() { Email result; using (EmailRepository repository = new EmailRepository()) { results = repository.GetById(1111); } Assert.IsTrue(results != null); } public class EmailRepository : RepositoryBase { public EmailRepository():base() { } } In my RepositoryBase public T GetById(object id) { using (var session = sessionFactory.OpenSession()) using (var transaction = session.BeginTransaction()) { try { T returnVal = session.Get(id); transaction.Commit(); return returnVal; } catch (HibernateException ex) { // Logging here transaction.Rollback(); return null; } } } The query time is very small. The resulting entity is really small. Subsequent queries are fine. Its seems to be getting the first session started. Has anyone else seen something similar?

Installing UCMA 3.0 and Creating a Communications Server "14"Trusted Application Pool

A lot of setup and administration tasks have gotten a lot easier in Communications Server 14; one of them is building an application server to develop and run your UCMA 3.0 applications on. In this post, Ill walk you through installing the UCMA 3.0 Core SDK and creating a Trusted Application Pool on the server, thus adding it to the Communications Server 14 topology and allowing you to host and run UCMA 3.0 applications on it. Note: These instructions will change slightly as the bits get updated for the eventual Beta release I will update this post as soon as I get a chance to run this setup on a more recent build. Im doing the install on a simple Communications Server 14 topology consisting of the following Windows Server 2008 R2 Hyper-V images: DC Domain Controller ExchangeUM Exchange Server 2010 CS-SE Microsoft Communications Server 2010 Standard Edition TS Development machine Ill walk through setting up UCMA 3.0 on the TS VM, which is a fully patched Windows Server 2008 R2 machine that is joined to the Fabrikam domain. Im also running Visual Studio 2010 on this VM because I intend to use it as a development machine. In a future post, Ill walk through installing just the UCMA 3.0 run time to build a true production UCMA application server. Im making a couple of assumptions here: You have an existing CS 2010 site and cluster configured(well look at this in a future post) Youre starting with a fully patched Windows Server 2008 R2 machine The machine is joined to your domain This walkthrough was done in my Fabrikam VM environment but can easily be modified for your own environment. Installing the UCMA 3.0 SDK Lets start by installing the UCMA 3.0 SDK. Run UcmaSdkWebDownload.msi to kick off the SDK installer package extract process. The installed package is extracted to C: >> Program Files >> Microsoft UCMA 3.0 >> SDK Installer Package. Browse there and run setup.exe. Click Install to install the UCMA 3.0 Core SDK and Workflow SDK. Install Communications Server Core Components UCMA 3.0 introduces a new concept called Auto-provisioning, which is most easily explained from the developer point of view. Remember what your app.config looked it in UCMA 2.0? You had to store the application GRUU, the trusted contact SIP Uri, the port for your application, and the name of the certificate authority. Thats all gone with auto-provisioning all you need in your app.config is your ApplicationId, e.g.: urn:application:MyApplication. How does CS 2010 do this? All of the applications configuration data is associated with the applications id. UCMA also queries a replicated copy of the Central Management Database to retrieve the applications configuration data and also the configuration data for any endpoints. In this step, well run Bootstrapper.exe to install the CS Core components, this checked for the following components and installs them if they are not already present: VcRedist Sqlexpress Sqlnativeclient Sqlbackcompat Ucmaredist OcsCore.msi Open a command window at C: >> Program Files >> Microsoft Communications Server 2010 >> Deployment and run the following command: Bootstrapper.exe /BootstrapReplica /MinCache /SourceDirectory:"%ProgramFiles%\Microsoft UCMA 3.0\SDK Installer Package\Prereq\BootstrapperCache" Create a New Trusted Application Pool The next step is to create a new trusted application pool for the new server. Fire up the Communications Server Management Shell from Start >> Microsoft Communications Server 2010 >> Communications Server Management Shell and enter the following PowerShell command: New-CsTrustedApplicationPool -Identity <FQDN of Server> -Registrar <FQDN of CS Server> -Site <CS Site Name> Verify that the new server was added to the CS topology by running the following PowerShell command: (Get-CsTopology -AsXml).ToString() > Topology.xml This created a file called Topology.xml in the directory that you ran the command from. Open the file and find the Clusters section and look for a node for the new server. The Cluster Fqdn is the name of your server, and note the name of the Site that this Cluster is a part of. <Cluster Fqdn="appsrv.fabrikam.com" RequiresReplication="true" RequiresSetup="true"> <ClusterId SiteId="UcMarketing2" Number="5" /> <Machine OrdinalInCluster="1" Fqdn="appsrv.fabrikam.com"> <NetInterface InterfaceSide="Primary" InterfaceNumber="1" IPAddress="0.0.0.0" /> </Machine> </Cluster> Configure CS Management Store Replication At this point, we have the CS Core components installed and the server configured as a trusted application pool. We now need to set up replication so that the Central Management Store replicates down to the new server. From the Communications Server Management Shell, run the following PowerShell command to enable the Replica service on the new server: Enable-CSReplica The Replica service is enabled, but hasn't done anything yet. This can be verified by running the following PowerShell command to check the replication status for the various servers in the topology: Get-CSManagementStoreReplicationStatus You can see in the screenshot below that the UpToDate property of the new server is still False Run the following PowerShell command to force the replication to run: Invoke-CSManagementStoreReplicationStatus Run Get-CSManagementStoreReplicationStatus again to verify that the new service is now up to date Request and Set a New Certificate The last step in the process is to request a new certificate from the certificate authority on the domain and assign it to the new server. From the Communications Server Management Shell, run the following PowerShell command to request a new certificate: Request-CSCertificate -Action new -Type default -CA <Domain Controller FQDN>\<Certificate Authority> Setting the -Verbose switch on the cmdlet creates an Xml file with its output. Open the Xml file and copy the thumbprint of the generated certificate. <?xml version="1.0" encoding="utf-8"?> <Action Name="Request-CsCertificate" Time="20100512T212258"> <Action Name="Request-CsCertificate" Time="20100512T212258"> <Info Title="Connection" Time="20100512T212258">Data Source=(local)\rtclocal;Initial Catalog=xds;Integrated Security=True</Info> <Action Time="20100512T212258"> <Info Title="Certificate use" Time="20100512T212258">urn:certref:default</Info> <Info Title="Subject distinguished name" Time="20100512T212258">CN="appsrv2.fabrikam.com"</Info> <Info Time="20100512T212259">The certificate request is submitted to the Certification Authority dc.fabrikam.com\FabrikamCA.</Info> <Info Time="20100512T212259">The certificate was issued.</Info> <Info Time="20100512T212259">The certificate was imported with thumbprint AFC3C46E459C1A39AD06247676F3555826DBF705.</Info> <Complete Time="20100512T212259" /> </Action> <Info Title="command status" Time="20100512T212259">Command execution processing completed</Info> <Action Name="DeploymentXdsCmdlet.SaveCachedItems" Time="20100512T212259"> <Info Time="20100512T212259">0 updates</Info> <Complete Time="20100512T212259" /> </Action> <Info Title="command status" Time="20100512T212259">Command has completed</Info> </Action> </Action> Run the following PowerShell command to set the certificate: Set-CsCertificate -Type Default -Thumbprint <Thumbprint> Wrapping Up You now have a new UCMA 3.0 application server in your Communications Server 2010 server topology. You can provision trusted applications and trusted application endpoints on the new server using the Communications Server 2010 Management Shell. Well take a look at how to do that in another post. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

Azure - Part 4 - Table Storage Service in Windows Azure

- by Shaun

In Windows Azure platform there are 3 storage we can use to save our data on the cloud. They are the Table, Blob and Queue. Before the Chinese New Year Microsoft announced that Azure SDK 1.1 had been released and it supports a new type of storage – Drive, which allows us to operate NTFS files on the cloud. I will cover it in the coming few posts but now I would like to talk a bit about the Table Storage. Concept of Table Storage Service The most common development scenario is to retrieve, create, update and remove data from the data storage. In the normal way we communicate with database. When we attempt to move our application over to the cloud the most common requirement should be have a storage service. Windows Azure provides a in-build service that allow us to storage the structured data, which is called Windows Azure Table Storage Service. The data stored in the table service are like the collection of entities. And the entities are similar to rows or records in the tradtional database. An entity should had a partition key, a row key, a timestamp and set of properties. You can treat the partition key as a group name, the row key as a primary key and the timestamp as the identifer for solving the concurrency problem. Different with a table in a database, the table service does not enforce the schema for tables, which means you can have 2 entities in the same table with different property sets. The partition key is being used for the load balance of the Azure OS and the group entity transaction. As you know in the cloud you will never know which machine is hosting your application and your data. It could be moving based on the transaction weight and the number of the requests. If the Azure OS found that there are many requests connect to your Book entities with the partition key equals “Novel” it will move them to another idle machine to increase the performance. So when choosing the partition key for your entities you need to make sure they indecate the category or gourp information so that the Azure OS can perform the load balance as you wish. Consuming the Table Although the table service looks like a database, you cannot access it through the way you are using now, neither ADO.NET nor ODBC. The table service exposed itself by ADO.NET Data Service protocol, which allows you can consume it through the RESTful style by Http requests. The Azure SDK provides a sets of classes for us to connect it. There are 2 classes we might need: TableServiceContext and TableServiceEntity. The TableServiceContext inherited from the DataServiceContext, which represents the runtime context of the ADO.NET data service. It provides 4 methods mainly used by us: CreateQuery: It will create a IQueryable instance from a given type of entity. AddObject: Add the specified entity into Table Service. UpdateObject: Update an existing entity in the Table Service. DeleteObject: Delete an entity from the Table Service. Beofre you operate the table service you need to provide the valid account information. It’s something like the connect string of the database but with your account name and the account key when you created the storage service on the Windows Azure Development Portal. After getting the CloudStorageAccount you can create the CloudTableClient instance which provides a set of methods for using the table service. A very useful method would be CreateTableIfNotExist. It will create the table container for you if it’s not exsited. And then you can operate the eneities to that table through the methods I mentioned above. Let me explain a bit more through an exmaple. We always like code rather than sentence. Straightforward Accessing to the Table Here I would like to build a WCF service on the Windows Azure platform, and for now just one requirement: it would allow the client to create an account entity on the table service. The WCF service would have a method named Register and accept an instance of the account which the client wants to create. After perform some validation it will add the entity into the table service. So the first thing I should do is to create a Cloud Application on my VIstial Studio 2010 RC. (The Azure SDK 1.1 only supports VS2008 and VS2010 RC.) The solution should be like this below. Then I added a configuration items for the storage account through the Settings section under the cloud project. (Double click the Services file under Roles folder and navigate to the Setting section.) This setting will be used when to retrieve my storage account information. Since for now I just in the development phase I will select “UseDevelopmentStorage=true”. And then I navigated to the WebRole.cs file under my WCF project. If you have read my previous posts you would know that this file defines the process when the application start, and terminate on the cloud. What I need to do is to when the application start, set the configuration publisher to load my config file with the config name I specified. So the code would be like below. I removed the original service and contract created by the VS template and add my IAccountService contract and its implementation class - AccountService. And I add the service method Register with the parameters: email, password and it will return a boolean value to indicates the result which is very simple. At this moment if I press F5 the application will be established on my local development fabric and I can see my service runs well through the browser. Let’s implement the service method Rigister, add a new entity to the table service. As I said before the entities you want to store in the table service must have 3 properties: partition key, row key and timespan. You can create a class with these 3 properties. The Azure SDK provides us a base class for that named TableServiceEntity in Microsoft.WindowsAzure.StorageClient namespace. So what we need to do is more simply, create a class named Account and let it derived from the TableServiceEntity. And I need to add my own properties: Email, Password, DateCreated and DateDeleted. The DateDeleted is a nullable date time value to indecate whether this entity had been deleted and when. Do you notice that I missed something here? Yes it’s the partition key and row key I didn’t assigned. The TableServiceEntity base class defined 2 constructors one was a parameter-less constructor which will be used to fill values into the properties from the table service when retrieving data. The other was one with 2 parameters: partition key and row key. As I said below the partition key may affect the load balance and the row key must be unique so here I would like to use the email as the parition key and the email plus a Guid as the row key. OK now we finished the entity class we need to store onto the table service. The next step is to create a data access class for us to add it. Azure SDK gives us a base class for it named TableServiceContext as I mentioned below. So let’s create a class for operate the Account entities. The TableServiceContext need the storage account information for its constructor. It’s the combination of the storage service URI that we will create on Windows Azure platform, and the relevant account name and key. The TableServiceContext will use this information to find the related address and verify the account to operate the storage entities. Hence in my AccountDataContext class I need to override this constructor and pass the storage account into it. All entities will be saved in the table storage with one or many tables which we call them “table containers”. Before we operate an entity we need to make sure that the table container had been created on the storage. There’s a method we can use for that: CloudTableClient.CreateTableIfNotExist. So in the constructor I will perform it firstly to make sure all method will be invoked after the table had been created. Notice that I passed the storage account enpoint URI and the credentials to specify where my storage is located and who am I. Another advise is that, make your entity class name as the same as the table name when create the table. It will increase the performance when you operate it over the cloud especially querying. Since the Register WCF method will add a new account into the table service, here I will create a relevant method to add the account entity. Before implement, I should add a reference - System.Data.Services.Client to the project. This reference provides some common method within the ADO.NET Data Service which can be used in the Windows Azure Table Service. I will use its AddObject method to create my account entity. Since the table service are not fully implemented the ADO.NET Data Service, there are some methods in the System.Data.Services.Client that TableServiceContext doesn’t support, such as AddLinks, etc. Then I implemented the serivce method to add the account entity through the AccountDataContext. You can see in the service implmentation I load the storage account information through my configuration file and created the account table entity from the parameters. Then I created the AccountDataContext. If it’s my first time to invoke this method the constructor of the AccountDataContext will create a table container for me. Then I use Add method to add the account entity into the table. Next, let’s create a farely simple client application to test this service. I created a windows console application and added a service reference to my WCF service. The metadata information of the WCF service cannot be retrieved if it’s deployed on the Windows Azure even though the <serviceMetadata httpGetEnabled="true"/> had been set. If we need to get its metadata we can deploy it on the local development service and then changed the endpoint to the address which is on the cloud. In the client side app.config file I specified the endpoint to the local development fabric address. And the just implement the client to let me input an email and a password then invoke the WCF service to add my acocunt. Let’s run my application and see the result. Of course it should return TRUE to me. And in the local SQL Express I can see the data had been saved in the table. Summary In this post I explained more about the Windows Azure Table Storage Service. I also created a small application for demostration of how to connect and consume it through the ADO.NET Data Service Managed Library provided within the Azure SDK. I only show how to create an eneity in the storage service. In the next post I would like to explain about how to query the entities with conditions thruogh LINQ. I also would like to refactor my AccountDataContext class to make it dyamic for any kinds of entities.

Dependency Injection in ASP.NET MVC NerdDinner App using Unity 2.0

- by shiju

In my previous post Dependency Injection in ASP.NET MVC NerdDinner App using Ninject, we did dependency injection in NerdDinner application using Ninject. In this post, I demonstrate how to apply Dependency Injection in ASP.NET MVC NerdDinner App using Microsoft Unity Application Block (Unity) v 2.0.Unity 2.0Unity 2.0 is available on Codeplex at http://unity.codeplex.com . In earlier versions of Unity, the ObjectBuilder generic dependency injection mechanism, was distributed as a separate assembly, is now integrated with Unity core assembly. So you no longer need to reference the ObjectBuilder assembly in your applications. Two additional Built-In Lifetime Managers - HierarchicalifetimeManager and PerResolveLifetimeManager have been added to Unity 2.0.Dependency Injection in NerdDinner using UnityIn my Ninject post on NerdDinner, we have discussed the interfaces and concrete types of NerdDinner application and how to inject dependencies controller constructors. The following steps will configure Unity 2.0 to apply controller injection in NerdDinner application. Step 1 – Add reference for Unity Application BlockOpen the NerdDinner solution and add reference to Microsoft.Practices.Unity.dll and Microsoft.Practices.Unity.Configuration.dllYou can download Unity from at http://unity.codeplex.com .Step 2 – Controller Factory for Unity The controller factory is responsible for creating controller instances.We extend the built in default controller factory with our own factory for working Unity with ASP.NET MVC. public class UnityControllerFactory : DefaultControllerFactory { protected override IController GetControllerInstance(RequestContext reqContext, Type controllerType) { IController controller; if (controllerType == null) throw new HttpException( 404, String.Format( "The controller for path '{0}' could not be found" + "or it does not implement IController.", reqContext.HttpContext.Request.Path)); if (!typeof(IController).IsAssignableFrom(controllerType)) throw new ArgumentException( string.Format( "Type requested is not a controller: {0}", controllerType.Name), "controllerType"); try { controller = MvcUnityContainer.Container.Resolve(controllerType) as IController; } catch (Exception ex) { throw new InvalidOperationException(String.Format( "Error resolving controller {0}", controllerType.Name), ex); } return controller; } } public static class MvcUnityContainer { public static IUnityContainer Container { get; set; } } Step 3 – Register Types and Set Controller Factory private void ConfigureUnity() { //Create UnityContainer IUnityContainer container = new UnityContainer() .RegisterType<IFormsAuthentication, FormsAuthenticationService>() .RegisterType<IMembershipService, AccountMembershipService>() .RegisterInstance<MembershipProvider>(Membership.Provider) .RegisterType<IDinnerRepository, DinnerRepository>(); //Set container for Controller Factory MvcUnityContainer.Container = container; //Set Controller Factory as UnityControllerFactory ControllerBuilder.Current.SetControllerFactory( typeof(UnityControllerFactory)); } Unity 2.0 provides a fluent interface for type configuration. Now you can call all the methods in a single statement.The above Unity configuration specified in the ConfigureUnity method tells that, to inject instance of DinnerRepositiry when there is a request for IDinnerRepositiry and inject instance of FormsAuthenticationService when there is a request for IFormsAuthentication and inject instance of AccountMembershipService when there is a request for IMembershipService. The AccountMembershipService class has a dependency with ASP.NET Membership provider. So we configure that inject the instance of Membership Provider.After the registering the types, we set UnityControllerFactory as the current controller factory. //Set container for Controller Factory MvcUnityContainer.Container = container; //Set Controller Factory as UnityControllerFactory ControllerBuilder.Current.SetControllerFactory( typeof(UnityControllerFactory)); When you register a type by using the RegisterType method, the default behavior is for the container to use a transient lifetime manager. It creates a new instance of the registered, mapped, or requested type each time you call the Resolve or ResolveAll method or when the dependency mechanism injects instances into other classes. The following are the LifetimeManagers provided by Unity 2.0ContainerControlledLifetimeManager - Implements a singleton behavior for objects. The object is disposed of when you dispose of the container.ExternallyControlledLifetimeManager - Implements a singleton behavior but the container doesn't hold a reference to object which will be disposed of when out of scope.HierarchicalifetimeManager - Implements a singleton behavior for objects. However, child containers don't share instances with parents.PerResolveLifetimeManager - Implements a behavior similar to the transient lifetime manager except that instances are reused across build-ups of the object graph.PerThreadLifetimeManager - Implements a singleton behavior for objects but limited to the current thread.TransientLifetimeManager - Returns a new instance of the requested type for each call. (default behavior)We can also create custome lifetime manager for Unity container. The following code creating a custom lifetime manager to store container in the current HttpContext. public class HttpContextLifetimeManager<T> : LifetimeManager, IDisposable { public override object GetValue() { return HttpContext.Current.Items[typeof(T).AssemblyQualifiedName]; } public override void RemoveValue() { HttpContext.Current.Items.Remove(typeof(T).AssemblyQualifiedName); } public override void SetValue(object newValue) { HttpContext.Current.Items[typeof(T).AssemblyQualifiedName] = newValue; } public void Dispose() { RemoveValue(); } } Step 4 – Modify Global.asax.cs for configure Unity container In the Application_Start event, we call the ConfigureUnity method for configuring the Unity container and set controller factory as UnityControllerFactory void Application_Start() { RegisterRoutes(RouteTable.Routes); ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new MobileCapableWebFormViewEngine()); ConfigureUnity(); }Download CodeYou can download the modified NerdDinner code from http://nerddinneraddons.codeplex.com

SQL Server and Hyper-V Dynamic Memory - Part 1

- by SQLOS Team

SQL and Dynamic Memory Blog Post Series Hyper-V Dynamic Memory is a new feature in Windows Server 2008 R2 SP1 that allows the memory assigned to guest virtual machines to vary according to demand. Using this feature with SQL Server is supported, but how well does it work in an environment where available memory can vary dynamically, especially since SQL Server likes memory, and is not very eager to let go of it? The next three posts will look at this question in detail. In Part 1 Serdar Sutay, a program manager in the Windows Hyper-V team, introduces Dynamic Memory with an overview of the basic architecture, configuration and monitoring concepts. In subsequent parts we will look at SQL Server memory handling, and develop some guidelines on using SQL Server with Dynamic Memory. Part 1: Dynamic Memory Introduction In virtualized environments memory is often the bottleneck for reaching higher VM densities. In Windows Server 2008 R2 SP1 Hyper-V introduced a new feature “Dynamic Memory” to improve VM densities on Hyper-V hosts. Dynamic Memory increases the memory utilization in virtualized environments by enabling VM memory to be changed dynamically when the VM is running. This brings up the question of how to utilize this feature with SQL Server VMs as SQL Server performance is very sensitive to the memory being used. In the next three posts we’ll discuss the internals of Dynamic Memory, SQL Server Memory Management and how to use Dynamic Memory with SQL Server VMs. Memory Utilization Efficiency in Virtualized Environments The primary reason memory is usually the bottleneck for higher VM densities is that users tend to be generous when assigning memory to their VMs. Here are some memory sizing practices we’ve heard from customers: · I assign 4 GB of memory to my VMs. I don’t know if all of it is being used by the applications but no one complains. · I take the minimum system requirements and add 50% more. · I go with the recommendations provided by my software vendor. In reality correctly sizing a virtual machine requires significant effort to monitor the memory usage of the applications. Since this is not done in most environments, VMs are usually over-provisioned in terms of memory. In other words, a SQL Server VM that is assigned 4 GB of memory may not need to use 4 GB. How does Dynamic Memory help? Dynamic Memory improves the memory utilization by removing the requirement to determine the memory need for an application. Hyper-V determines the memory needed by applications in the VM by evaluating the memory usage information in the guest with Dynamic Memory. VMs can start with a small amount of memory and they can be assigned more memory dynamically based on the workload of applications running inside. Overview of Dynamic Memory Concepts · Startup Memory: Startup Memory is the starting amount of memory when Dynamic Memory is enabled for a VM. Dynamic Memory will make sure that this amount of memory is always assigned to the VMs by default. · Maximum Memory: Maximum Memory specifies the maximum amount of memory that a VM can grow to with Dynamic Memory. · Memory Demand: Memory Demand is the amount determined by Dynamic Memory as the memory needed by the applications in the VM. In Windows Server 2008 R2 SP1, this is equal to the total amount of committed memory of the VM. · Memory Buffer: Memory Buffer is the amount of memory assigned to the VMs in addition to their memory demand to satisfy immediate memory requirements and file cache needs. Once Dynamic Memory is enabled for a VM, it will start with the “Startup Memory”. After the boot process Dynamic Memory will determine the “Memory Demand” of the VM. Based on this memory demand it will determine the amount of “Memory Buffer” that needs to be assigned to the VM. Dynamic Memory will assign the total of “Memory Demand” and “Memory Buffer” to the VM as long as this value is less than “Maximum Memory” and as long as physical memory is available on the host. What happens when there is not enough physical memory available on the host? Once there is not enough physical memory on the host to satisfy VM needs, Dynamic Memory will assign less than needed amount of memory to the VMs based on their importance. A concept known as “Memory Weight” is used to determine how much VMs should be penalized based on their needed amount of memory. “Memory Weight” is a configuration setting on the VM. It can be configured to be higher for the VMs with high performance requirements. Under high memory pressure on the host, the “Memory Weight” of the VMs are evaluated in a relative manner and the VMs with lower relative “Memory Weight” will be penalized more than the ones with higher “Memory Weight”. Dynamic Memory Configuration Based on these concepts “Startup Memory”, “Maximum Memory”, “Memory Buffer” and “Memory Weight” can be configured as shown below in Windows Server 2008 R2 SP1 Hyper-V Manager. Memory Demand is automatically calculated by Dynamic Memory once VMs start running. Dynamic Memory Monitoring In Windows Server 2008 R2 SP1, Hyper-V Manager displays the memory status of VMs in the following three columns: · Assigned Memory represents the current physical memory assigned to the VM. In regular conditions this will be equal to the sum of “Memory Demand” and “Memory Buffer” assigned to the VM. When there is not enough memory on the host, this value can go below the Memory Demand determined for the VM. · Memory Demand displays the current “Memory Demand” determined for the VM. · Memory Status displays the current memory status of the VM. This column can represent three values for a VM: o OK: In this condition the VM is assigned the total of Memory Demand and Memory Buffer it needs. o Low: In this condition the VM is assigned all the Memory Demand and a certain percentage of the Memory Buffer it needs. o Warning: In this condition the VM is assigned a lower memory than its Memory Demand. When VMs are running in this condition, it’s likely that they will exhibit performance problems due to internal paging happening in the VM. So far so good! But how does it work with SQL Server? SQL Server is aggressive in terms of memory usage for good reasons. This raises the question: How do SQL Server and Dynamic Memory work together? To understand the full story, we’ll first need to understand how SQL Server Memory Management works. This will be covered in our second post in “SQL and Dynamic Memory” series.

SQL Server and Hyper-V Dynamic Memory - Part 1

- by SQLOS Team

SQL and Dynamic Memory Blog Post Series Hyper-V Dynamic Memory is a new feature in Windows Server 2008 R2 SP1 that allows the memory assigned to guest virtual machines to vary according to demand. Using this feature with SQL Server is supported, but how well does it work in an environment where available memory can vary dynamically, especially since SQL Server likes memory, and is not very eager to let go of it? The next three posts will look at this question in detail. In Part 1 Serdar Sutay, a program manager in the Windows Hyper-V team, introduces Dynamic Memory with an overview of the basic architecture, configuration and monitoring concepts. In subsequent parts we will look at SQL Server memory handling, and develop some guidelines on using SQL Server with Dynamic Memory. Part 1: Dynamic Memory Introduction In virtualized environments memory is often the bottleneck for reaching higher VM densities. In Windows Server 2008 R2 SP1 Hyper-V introduced a new feature “Dynamic Memory” to improve VM densities on Hyper-V hosts. Dynamic Memory increases the memory utilization in virtualized environments by enabling VM memory to be changed dynamically when the VM is running. This brings up the question of how to utilize this feature with SQL Server VMs as SQL Server performance is very sensitive to the memory being used.
