  • WCF error service error message with shared classes

    - by sevenalive
    Source code: http://code.google.com/p/sevenupdate/source/browse/#hg/Source/SevenUpdate.Base SevenUpdate.Base.Sui cannot be used since it does not match imported DataContract. Need to exclude this type from referenced types. Now I tried unchecking reuse reference types and I was able to get my project to compile. but when sending a collection from the client it was never received or couldn't be deserialized on the server end. I really need this to work. Any help would be appreciated, the fullsource code is provided by google code.

  • WCF: what timeout property to use?

    - by Tom234
    I have a piece of code like so NetTcpBinding binding = new NetTcpBinding(SecurityMode.Transport); binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows; binding.CloseTimeout = new TimeSpan(0, 0, 1); binding.OpenTimeout = new TimeSpan(0, 0, 1); binding.SendTimeout = new TimeSpan(0, 0, 1); binding.ReceiveTimeout = new TimeSpan(0, 0, 1); EndpointAddress endPoint = new EndpointAddress(new Uri(clientPath)); DuplexChannelFactory<Iservice> channel = new DuplexChannelFactory<Iservice>(new ClientCallBack(clientName), binding, endPoint); channel.Ping() When the endpoint doesn't exist it still waits 20seconds before throwing an EndpointNotFoundException. The weird thing is that when i changed the SendTimeout the exception message changed from The connection attempt lasted for a time span of 00:00:20 to ....01 but still took 20seconds to throw the exception! How can i change this timeout?

  • WCF-endpoint listening

    - by sekar
    There was no endpoint listening at http;//localhost:8080/xdxservice/xdsrepository that could accept the message. This is often caused by an incorrect address or SOAP action.

  • Concurrent WCF calls via shared channel

    - by Kent Boogaart
    I have a web tier that forwards calls onto an application tier. The web tier uses a shared, cached channel to do so. The application tier services in question are stateless and have concurrency enabled. But they are not being called concurrently. If I alter the web tier to create a new channel on every call, then I do get concurrent calls onto the application tier. But I wanted to avoid that cost since it is functionally unnecessary for my scenario. I have no session state, and nor do I need to re-authenticate the caller each time. I understand that the creation of the channel factory is far more expensive than than the creation of the channels, but it is still a cost I'd like to avoid if possible. I found this article on MSDN that states: While channels and clients created by the channels are thread-safe, they might not support writing more than one message to the wire concurrently. If you are sending large messages, particularly if streaming, the send operation might block waiting for another send to complete. Firstly, I'm not sending large messages (just a lot of small ones since I'm doing load testing) but am still seeing the blocking behavior. Secondly, this is rather open-ended and unhelpful documentation. It says they "might not" support writing more than one message but doesn't explain the scenarios under which they would support concurrent messages. Can anyone shed some light on this?

  • vsts load testing wcf app

    - by ashish.s
    I have a simple test written like this public class Test { [ThreadStatic] private static ServiceClient client; [TestMethod] public void TestCase1() { If( client == null) { .... //instantiate client } client.CallMyServiceMethod() } [TestMethod] public void TestCase2() { using(var newClient = new ServiceClient()) { newClient.CallMyServiceMethod() } } The percentage of new users is set to 100 % for the test, and the user load is constant load of 1. But the response time for TestCase1 is about 3 times better than TestCase2. Can someone see what i am missing here ? many thanks

  • Windows service hangs

    - by Ram
    Hi, I have a webdav client-server application. I'm using Cassini webserver to host the webdav server. One important thing here is that I start and Stop my webserver using a windows service. Now, I start my windows service and I attach my webdav server application's debugger to the windows service. Everything used to go fine, that is I could connect to the server using my webdav client, debug the server code. However, a couple of days back, when I tried to debug my webdav server application, which in turn is attached to a windows service, my computer freezes while I'm in the midst of debugging the server app. The freeze does not occur at the same line every time and is therefore not predictable. Every time this happens, I would not be able to do anything at all with my computer except to reboot the system using the power button. What could be the problem? Could it be the service that is freezing or something else? Any help? Thanks, Ram

  • What is the difference between building a WSDL in Eclipse and using WCF?

    - by myermian
    I'm somewhat familiar with WCF in that I can build Web Services in VS.Net ... I understand some of the concepts... But, the other day I cam across this option in Eclipse (I also use Java to code) to create a WSDL. Playing around with it it looks great since it has a GUI method of building itself. I guess I just wanna know what the difference is. 1) Are they different technologies like WSDL vs WCF? Or, is it that WCF uses WSDLs? 2) I read that WSDLs are a top-down approach... so what about WCF, is that top-down or is that bottom-up? 3) Will this WSDL in Eclipse actually be able to generate CSharp code for my server and client efficiently, or will it require a lot of fixing?

  • JBoss Clustered Service that sends emails from txt file

    - by michael lucas
    I need a little push in the right direction. Here's my problem: I have to create an ultra-reliable service that sends email messages to clients whose addresses are stored in txt file on FTP server. Single txt file may contain unlimited number of entries. Most often the file contains about 300,000 entries. Service exposes interface with just two simple methods: TaskHandle sendEmails(String ftpFilePath); ProcessStatus checkProcessStatus(TaskHandle taskHandle); Method sendEmails() returns TaskHandle by which we can ask for ProcessStatus. For such a service to be reliable clustering is necessary. Processing single txt file might take a long time. Restarting one node in a cluster should have no impact on sending emails. We use JBoss AS 4.2.0 which comes with a nice HASingletonController that ensure one instance of service is running at given time. But once a fail-over happens, the second service should continue work from where the first one stopped. How can I share state between nodes in a cluster in such a way that leaves no possibility of sending some emails twice?

  • destroy an android service

    - by Jack Trowbridge
    I am using a service in my android app, which is called when an alarm is activated by a calander. When the service has been activated i want it to be destroyed by the OnStart() method once it has completed its code. My OnStart() method: @Override public void onStart(Intent intent, int startId) { super.onStart(intent, startId); Vibrator vi = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); vi.vibrate(5000); Toast.makeText(this, "MyAlarmService.onStart()", Toast.LENGTH_LONG).show(); //CODE HERE TO DESTROY SERVICE?? } This bassically means when the service is called it runs the code in the OnStart() method and i want it to destroy itself. Any Ideas, methods that would do this?. Thanks, jack.

  • Using WCF in .NET how can I make it auto generate SOAP docs like ASMX did?

    - by Hades
    I'm currently writing a web service using WCF in VB.NET. Previous web services I wrote used ASMX but I wanted to learn WCF and so far it's going well. I actually prefer the way WCF does things. One thing I miss however is the way that ASMX used to generate example SOAP requests and responses. It was like getting documentation for free. Is there anyway to auto generate SOAP documentation for WCF? If not, is there any way to generate it in a .NET page using the WSDL?

  • Best practice for error handling in an Android Service

    - by Omar Kohl
    I have an Android Service that does some background processing on an image using a separate Thread. If an error occurs in this Service or even worse in the thread, what is the best practice to inform the launching Activity of the problem and allow the application to recover to a stable state (i.e. the state it was in before launching the service). From within the Service I could post a Toast or a Notification, but that doesn't help me. I would like to inform the user about the problem but at the same time recover the application to a stable state.

  • WCF DataContract class with methods

    - by jmlaplante
    This is more of a philosophical/best-practice sort of question rather than a technical problem. Are there any strong arguments against writing a DataContract class with methods that are to be used server-side only? Or what about additional properties that are not decorated with the DataMember attribute? For example: [DataContract] public class LogEntry { [DataMember] public string Message { get; set; } [DataMember] public string Severity { get; set; } public string SomeOtherProperty { get; set; } ... public void WriteToDatabase() { ... } } Not doing it seems like an awful lot of extra work that I would prefer to avoid, although using extension methods could make it easier. But, as a good developer, I am wondering if it is bad practice to do so.

  • A Patent for Workload Management Based on Service Level Objectives

    - by jsavit
    I'm very pleased to announce that after a tiny :-) wait of about 5 years, my patent application for a workload manager was finally approved. Background Many operating systems have a resource manager which lets you control machine resources. For example, Solaris provides controls for CPU with several options: shares for proportional CPU allocation. If you have twice as many shares as me, and we are competing for CPU, you'll get about twice as many CPU cycles), dedicated CPU allocation in which a number of CPUs are exclusively dedicated to an application's use. You can say that a zone or project "owns" 8 CPUs on a 32 CPU machine, for example. And, capped CPU in which you specify the upper bound, or cap, of how much CPU an application gets. For example, you can throttle an application to 0.125 of a CPU. (This isn't meant to be an exhaustive list of Solaris RM controls.) Workload management Useful as that is (and tragic that some other operating systems have little resource management and isolation, and frighten people into running only 1 app per OS instance - and wastefully size every server for the peak workload it might experience) that's not really workload management. With resource management one controls the resources, and hope that's enough to meet application service objectives. In fact, we hold resource distribution constant, see if that was good enough, and adjust resource distribution if that didn't meet service level objectives. Here's an example of what happens today: Let's try 30% dedicated CPU. Not enough? Let's try 80% Oh, that's too much, and we're achieving much better response time than the objective, but other workloads are starving. Let's back that off and try again. It's not the process I object to - it's that we to often do this manually. Worse, we sometimes identify and adjust the wrong resource and fiddle with that to no useful result. Back in my days as a customer managing large systems, one of my users would call me up to beg for a "CPU boost": Me: "it won't make any difference - there's plenty of spare CPU to be had, and your application is completely I/O bound." User: "Please do it anyway." Me: "oh, all right, but it won't do you any good." (I did, because he was a friend, but it didn't help.) Prior art There are some operating environments that take a stab about workload management (rather than resource management) but I find them lacking. I know of one that uses synthetic "service units" composed of the sum of CPU, I/O and memory allocations multiplied by weighting factors. A workload is set to make a target rate of service units consumed per second. But this seems to be missing a key point: what is the relationship between artificial 'service units' and actually meeting a throughput or response time objective? What if I get plenty of one of the components (so am getting enough service units), but not enough of the resource whose needed to remove the bottleneck? Actual workload management That's not really the answer either. What is needed is to specify a workload's service levels in terms of externally visible metrics that are meaningful to a business, such as response times or transactions per second, and have the workload manager figure out which resources are not being adequately provided, and then adjust it as needed. If an application is not meeting its service level objectives and the reason is that it's not getting enough CPU cycles, adjust its CPU resource accordingly. If the reason is that the application isn't getting enough RAM to keep its working set in memory, then adjust its RAM assignment appropriately so it stops swapping. Simple idea, but that's a task we keep dumping on system administrators. In other words - don't hold the number of CPU shares constant and watch the achievement of service level vary. Instead, hold the service level constant, and dynamically adjust the number of CPU shares (or amount of other resources like RAM or I/O bandwidth) in order to meet the objective. Instrumenting non-instrumented applications There's one little problem here: how do I measure application performance in a way relating to a service level. I don't want to do it based on internal resources like number of CPU seconds it received per minute - We need to make resource decisions based on externally visible and meaningful measures of performance, not synthetic items or internal resource counters. If I have a way of marking the beginning and end of a transaction, I can then measure whether or not the application is meeting an objective based on it. If I can observe the delay factors for an application, I can see which resource shortages are slowing an application enough to keep it from meeting its objectives. I can then adjust resource allocations to relieve those shortages. Fortunately, Solaris provides facilities for both marking application progress and determining what factors cause application latency. The Solaris DTrace facility let's me introspect on application behavior: in particular I can see events like "receive a web hit" and "respond to that web hit" so I can get transaction rate and response time. DTrace (and tools like prstat) let me see where latency is being added to an application, so I know which resource to adjust. Summary After a delay of a mere few years, I am the proud creator of a patent (advice to anyone interested in going through the process: don't hold your breath!). The fundamental idea is fairly simple: instead of holding resource constant and suffering variable levels of success meeting service level objectives, properly characterise the service level objective in meaningful terms, instrument the application to see if it's meeting the objective, and then have a workload manager change resource allocations to remove delays preventing service level attainment. I've done it by hand for a long time - I think that's what a computer should do for me.

  • Robust Large File Transfer with WCF

    - by Sharov
    I want to transfer big files (1GB) over unreliable transport channels. When connection is interrupted, I don't want start file transfering from the begining. I can partially store it in a temp table and store last readed position, so when connection is reestablished I can request continue uploading of file from this position. Is there any best-practice for such kind of things. I'm currently use chunking channel.

  • .NET Windows Service, threads and garbage collection (possible memory leaks)

    - by Evgeny
    I am developing a .NET Windows service that is creating a couple of threads and then uses these threads to send print jobs to printers (there is a thread for each printer). I have some issues which sometimes can be fixed by restarting the service. Some issues also arise when the service has been running for a while. This makes me suspect a possible memory leak. So, a couple of questions: Would a garbage collector collect an object if it was created inside a thread, or will the object exist until the thread is stopped/terminated? What tools can I use to monitor the amount of memory used by a Windows service and by a thread that I am starting programmatically?

  • wcf possible to override the dipose of proxy

    - by pdiddy
    I'd like to override the Dispose method of generated proxy (ClientBase) because of the fact that disposing of a proxy calls Close and can throw an exception when the channel is faulted. The only way I came up was to create a partial class to my generatedproxy, make it inherit from IDisposable. : public partial class MyServiceProxy : IDisposable { #region IDisposable Members public void Dispose() { if (State != System.ServiceModel.CommunicationState.Faulted) Close(); else Abort(); } #endregion } I did some test and my Dipose method is indeed called. Do you see any issue with this strategy? Also, I don't like the fact that I'll have to create this partial class for every generated proxy. It be nice if I was able to make my proxy inherit from a base class...

  • Silverlight Business Application template with WCF is throwing warning.

    - by Manoj
    Hi, I am using the Silvelight Business Application template. I wrote a function which uses Membership.getUserList function to return the user list. I tried exposing it as Service using WCF. But when I try to compile the client side code it throws a warning saying "Client Proxy Generation for user_authentication.Web.Service1 failed'. Why does it happen? The complete warning message is: Warning 4 Client proxy generation for service 'user_authentication.Web.Service1' failed: Generating metadata files... Warning: Unable to load a service with configName 'user_authentication.Web.Service1'. To export a service provide both the assembly containing the service type and an executable with configuration for this service. Details:Either none of the assemblies passed were executables with configuration files or none of the configuration files contained services with the config name 'user_authentication.Web.Service1'. Warning: No metadata files were generated. No service contracts were exported. To export a service, use the /serviceName option. To export data contracts, specify the /dataContractOnly option. This can sometimes occur in certain security contexts, such as when the assembly is loaded over a UNC network file share. If this is the case, try copying the assembly into a trusted environment and running it.
