• Long running stateful service in .NET

  - by Asaf R

  Hi, I need to create a service in .NET that maintains (inner) state in-memory, spawns multiple threads and is generally long-running. There are a lot options - Good-old Windows Service Windows Communication Services Windows Workflow Foundation I really don't know which to choose. Most of the functionality is in a library used by this service, so the service itself is rather simple. On one hand, it's important the service host is as close to "simply working" as possible, which excludes Windows Service. On the other hand, it's important that the service is not taken down by the host just because there's no external activity, which makes WCF kind o' "scary". As for WF, it's strongest selling point is the ability to create processes as, um..., workflows, which is something I don't need nor want. To sum it up, the plethora of Microsoft technologies got me a bit confused. I'd appreciate help regarding the pros and cons of each solution (or other's I've failed to mention) for the problem of a stateful, long running service in .NET Thanks, Asaf P.S., I'm using .NET 4. EDIT: What I mean by the host "simply working" is, for example, that the service I create be reactivated if it crashes. I guess the reason for this question is that I've created Windows Services in the past (I think it was in plain C++ with Win32 API), and I don't want to miss out on something simpler if there's is such as thing. Thanks for all the replies thus far! Asaf.

• wcf 4.0 service on IIS7

  - by Jan

  I am currently developing a service with wcf 4.0 (visual studio 2010 RC). When I try my service on the Visual Studio Development Server, it all works perfect. However, when I tree to run my service on IIS7 on a windows 7 machine, the service doesn't work anymore. (I already changed the framework version on my application pool). When I call an operation on the service, like the default operation GetData when I create a service, I get an error. I used the WCF test client to connect to the service. When I call the operation on the service, the Visual Studio Just-In-Time debugger shows the following message: An unhandled win32 exception occured in w3wp.exe The Just-In-Time debugger was launched without necessary security permissions. To debug this proces, the JIT debugger must be run as an administrator. Would you like to debug the proces? As far as I know, I am running Visual Studio as an administrator and this is probably the process that starts the JIT debugger. The only option I have is to debug the W3WP process, which is probably not the right thing to do. What can I do the make the Service to run on IIS7?

• How to establish a two-way communication between Activity and Service in different process?

  - by steff

  Hi everyone, I'm working on establishing a two-way communication between an Activity and a Service which runs in a different process. Querying the process from the Activity is no big deal. But I want the process to notify the Activity on events. The idea behind it is this: the service runs independently from the actual app. It queries a webserver periodically. If a new task is found on the webserver the process should notify the activity. I found this thread over at AndDev.org but it doesn't seem to work for me. I've been messing around with BroadcastReceiver. I've implemented an interface which should notify the Activity but the problem is that the listener is always null since the Broadcast from the process is done via Intent, hence the class that extends BroadcastReceiver will be newly instantiated. How can I establish a 2-way communication? This has to be possible. Thanks for any help, steff

• C# client to Java web service

  - by tomislavg

  I have received wsdl file from outside company. I'm using VS2005 c#. With wsdl.exe I have created class containing methods and types for the given web service. To connect to the service outside company requires that certificate from the smart card is inputed in the header. I think i have achieved this with service.ClientCertificates.Add("Path to exported cert" - at least for now, after probably later i will take it from Certificate Store When service is called there are three steps that are taken and visible by the Fidller(Web Debugging Proxy)). service is called on the url http://test.company.com/webservice.wsdl service redirects the request to certificate server and pin needs to be inputed to get cookie for the server service is again redirected to url http://test.company.com/webservice.wsdl At point 1. I can see that my request send to the server contains .... but at point 3. i can not see request` just a empty string. The exception is thrown Msg: Possible SOAP version mismatch: Envelope namespace http://schemas.xmlsoap.org/wsdl/ was unexpected. Expecting http://schemas.xmlsoap.org/soap/envelope/. Does somebody have an example how to connect to java web service with certificate and AlowRedirect enabled for the web service? Any ideas what i am doing wrong are more that welcome.

• Consuming WCF Web Service

  - by Debby

  Hi, I have a simple web service running and I have a console application client consuming the service. I did have issues getting this running and I had been helped by some wonderful people in this community. I have another problem: if I want to call the service from the client in a loop, it doesn't work. It works only for the first time and then it just keeps waiting. Why is this happening and how can I resolve it. The code: namespace WebService { [ServiceContract] public interface IService { [OperationContract(Name="Result")] [WebGet(UriTemplate = "/")] Stream Result(); } public class Service:IService { public Stream Result() { // read a file from the server and return it as stream } } } The client: namespace WebServiceClient { [ServiceContract] public interface IService { [OperationContract(Name="Result")] [WebGet(UriTemplate = "/")] Stream Result(); } } static void Main() { Console.WriteLine("Press enter when the service is available"); Console.ReadLine(); // creating factory HttpChunkingBinding binding = new HttpChunkingBinding(); binding.MaxReceivedMessageSize = 0x7fffffffL; ChannelFactory<WebServiceClient.IService> factory = new ChannelFactory<WebServiceClient.IService> (binding, new EndpointAddress("http://localhost/WebService/Service")); WebServiceClient.IService service = factory.CreateChannel(); for(int i = 0; i < 10; i++) { Stream s = service.Result(); // write this stream to a file and close the stream } //Closing our channel. ((IClientChannel)service).Close(); } Thanks,

• connecting to a webservice from android - AsyncTask or Service?

  - by football

  I'm writing an android app that will connect to a REST/JSON webservice. Users will be retrieving information, uploading comments, downloading and uploading images etc. I know that I shouldn't keep all this network communication in the Activity/UI thread, as it will cause ANRs. What I'm confused about is whether I should use an AsyncTask or a Service with "manual" threading to accomplish this; With a Service, I'd simply have a public method for each method in the webservice's API. I'd then implement threading within each of these methods. If I used an AsyncTask, I would create a helper class that defined AsyncTasks for each method in the webservice's API. Which method is preferred? Interaction with the webservice will only happen while the user is in the Activity. Once they switch to another application, or exit the program, there is no need for communication with the webservice.

• How to control the memory size of continuously running windows service?

  - by Snowill

  Hi, I have created a windows service which is continuously polling a database. For this purpose i have a timer in place. Ever time i am querying a database table i open a connection and close it immediately after my work is done. Right now i am doing this every 20 seconds for testing purpose, but later this time might increase to 5 - 10 minutes. What happens is everytime the database table is polled there is an increase of 10-12 KB in the size of the memory of the service running. This i can see in the task manager. Is there any way to control this.

• Service Bus / Request Forwarding

  - by codputer

  I'm doing some development with a thrid party that issues either a Get or POST to a public URL that I specify. What I would like to do is set up a Relay service on the Azure Service Bus that my dev machine can listen to. When the request comes in, I want to forward that request as if my web service was taking the request directly from the thrid party service. When I'm ready, I'll deploy the application to a public service, change the URL that the thrid party service is sending too, and viola I should be up and running. What I'm looking for looks exactly like this: Clemens the Master of Service Bus but it's from the 2009 CTP. I'm working at it, but haven't yet got it working using all the new bits in 2012 (a.ka. its over my head at the moment). Somebody want to help? Clemens also help somebody else create a Reverse Proxy using the Service Bus, but I can't seem to find it. Yes I've also tweeted Clemens, but I'm sure he is a busy man! p.s. I know about Application Request Routing, but my dev machine is not on a public URL, I need to rewrite the URL after my client listener on the service bus recieves the message that was relayed from the Server side endpoint.

• How to run an executable as a system service?

  - by byanity

  I've got a file and data distribution application written in .NET 2.0 I've written similar to Steam. This application will need to run in Windows 7 and will need to be able to run and install applications that require administrator rights. However the users will not have admin rights. My thought was to run the application as a Local System Service. I figured by doing this the application could perform admin rights actions (registry edits, launching apps, etc) when the user isn't an admin. Are my assumptions correct? What steps do I need to take to have this app install as a Local System Service? An Administrator will be installing the application but it will be run by a user without Administrator rights. Thanks in advance!

• Locking a file to verify a single execution of a service. How reliable?

  - by Camilo Díaz

  Hello, I am deploying a little service to an UNIX(AIX) system. I want to check if there is no active instance of that service running when starting it. How reliable is to implement that check like this? Try to acquire a lock on a file (w/ FileChannel) If succeeds, keep lock and continue execution If fails, exit and refuse to run the main body I am aware of software like the Tanuki wrapper, however, I'm longing for a simpler(maybe not portable) solution. Regarding PIDFILE(s): I want to avoid using them if possible, as I don't have administrative rights on the machine, neither knowledge in AIX's shell programming.

• Definitive list of service providers in Visual Studio 2010?

  - by Will

  VS2010 has made it easy to write extensions via MEF exports and imports. However, if you want to do anything useful you have to know what service provider(s) you need to implement your super awesoem extension. Unfortunately, this information is often spread out all over the place, not well documented or both. What I'd really love to see is a comprehensive list of all service providers that you can import into your VS extension, and what those providers... um, provide. Has anybody seen something like that?

• Android Service setForeground While Display Sleeps

  - by c12

  I have a background Android Service that's purpose is to communicate with another device (non-phone) using a Bluetooth socket. Everything works fine except that the service gets stopped and restarted by the OS when the phone display is sleeping. This restart sometimes leaves a 15-20 minute gaps where there is no communication between the Service and the Bluetooth device and I need to be able to query the device every minute. Is startForeground the proper approach? Attempted to use: startForeground(int, Notification) //still see gaps when phone sleeps Service: public class ForegroundBluetoothService extends Service{ private boolean isStarted = false; @Override public void onDestroy() { super.onDestroy(); stop(); } /** * @see android.app.Service#onBind(android.content.Intent) */ @Override public IBinder onBind(Intent intent) { return null; } /** * @see android.app.Service#onStartCommand(android.content.Intent, int, int) */ @Override public int onStartCommand(Intent intent, int flags, int startId) { loadServiceInForeground(); return(START_STICKY); } private void loadServiceInForeground() { if (!isStarted) { isStarted=true; Notification notification = new Notification(R.drawable.icon, "Service is Running...", System.currentTimeMillis()); Intent notificationIntent = new Intent(this, MainScreen.class); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(this, "Notification Title", "Service is Running...", pendingIntent); startForeground(12345, notification); try{ queryTheBluetoothDevice(); } catch(Exception ex){ ex.printStackTrace(); } } } private void stop() { if (isStarted) { isStarted=false; stopForeground(true); } } }

• Is it possible to run a hidden console application from a Windows service?

  - by norgepaul

  I've written a server in Delphi 2010 that needs to launch a console application every now and again to back up a database. The console application can send log information to the console window, but it is not required. This works fine when running as an application, but when run as a service I get an access violation when launching the console application. This is the case even if I launch it hidden (SW_HIDE). Is it possible to launch a hidden console application from a Windows service? The solution needs to work on XP, Vista and Windows 7.

• How to invoke RESTful WCF service method with multiple parameters?

  - by Scythe

  I have a RESTful WCF service with a method declared like this: [OperationContract(Name = "IncrementAge")] [WebInvoke(UriTemplate = "/", Method = "POST", ResponseFormat = WebMessageFormat.Json)] Person IncrementAge(Person p); Here's the implementation: public Person IncrementAge(Person p) { p.age++; return p; } So it takes the Person complex type, increments the age property by one, and spits it back, using JSON serialization. I can test the thing by sending a POST message to the service like this: POST http://localhost:3602/RestService.svc/ HTTP/1.1 Host: localhost:3602 User-Agent: Fiddler Content-Type: application/json Content-Length: 51 {"age":25,"firstName":"Hejhaj","surName":"Csuhaj"} This works. What if I'd like to have a method like this? Person IncrementAge(Person p, int amount); So it'd have multiple parameters. How should I construct the POST message for this to work? Is this possible? Thanks

• Changing Endpoint URL for a Web Service Data Control

  - by vishal.s.jain(at)oracle.com

  When you move your application from Development to Production, there is more often then not, a need to change the web service endpoint URL in your ADF application. If you are using a Web Service Data Control(WSDC), you can do this in more than one ways. The following example illustrates how this can be done.At Design TimeIf the application workspace is in your control, you can quickly do this by updating the definition in DataControl.dcx file:Along with this, you will also need to change the endpoint in connections.xml. So invoke the Edit Connections dialog: Then, change the endpoint URL.At DeploymentAnother way to change is changing the endpoint at the ear level, at deployment. So when you select Deploy -> Application Server at the Application level, it will bring up a Deployment Configuration dialog, in which you can edit the WSDL URL:Also, change the Port URL:At Post DeploymentIf your need to change this post deployment, you can do it through Oracle Enterprise Manager. But for this, your application needs to be configured with a writable MDS repository. It is recommended you use a Database MDS store during deployment. So have your application configured (by having an entry in adf-config.xml) and server configured (by having a MDS store registered). Once done, you can configure the ADF Connection in EM for this application:Change the WSDL location here on 'Edit':Also, change the Port using Advance Connection Configuration:Change the Endpoint Address here:Apply Changes and you are done!

• What is start_daemon?

  - by David Parks

  I'm trying to understand start_daemon in the following /etc/init.d/nagios-nrpe-server startup script: start) if [ "$INETD" = 1 ]; then exit 1 fi log_daemon_msg "Starting $DESC" "$NAME" start_daemon -p $PIDDIR/nrpe.pid $NICENESS $DAEMON -c $CONFIG -d $DAEMON_OPTS log_end_msg $? ;; In particular, when I start this service it isn't writing a PID file as expected, thus the stop service nagios-nrpe-server command is not working (I need to manually kill the processes). I'm trying to figure out how to trouble shoot the problem, but I can't run start_daemon ... from the command line. I want to reproduce what the script is doing manually so I can work on what the problem is.

• Partner Webcast – Platform as a Service with Oracle WebLogic and OpenStack

  - by Thanos Terentes Printzios

  Platform as a service is defined as Platform that facilitates the deployment of applications without the complexity of buying and managing the underlying hardware and software and provisioning hosting capabilities. For Java EE, that would mean an elastic Java EE platform, where the user (IT admin) deploys the application, and then the platform itself takes care of meeting the SLA. With combination of Oracle WebLogic 12c with Dynamic Clusters, Oracle Solaris 11.2 with OpenStack and some scripting, we can completely automate infrastructure and platform provisioning, effectively providing PaaS to the IT users. Join us in this webcast as explore the usage of Weblogic 12c with Openstack, to establish Platform as a Service.

• Windows Server (SBS) 2008 - Telephony service won't start (missing permissions)

  - by Uri

  I am running a SBS 2008 server. It's setup as the domain controller for the network. After a reboot, the Telephony service (and all services that depend on it) refuses to start under the Network Service account. The error given is: Error 1297: A privilege that the service requires to function properly does not exist in the service account configuration. You may use the Services Microsoft Management Console (MMC) snap-in (services.msc) and the Local Security Settings MMC snap-in (secpol.msc) to view the service configuration and the account configuration. This has caused all the network services not to be accessible e.g. terminal services, VPN (RRAS), SQL Server instances. The SSH daemon I have running on the box will accept connections only from localhost, but won't respond on the network. After searching around, the only advice I could find was to grant the Network Service account these permissions: Adjust memory quotas for a process Replace a process level token I set those permissions on both the Default Domain Policy and the Default Domain Controller Policy, but it seemingly had no effect. Most of the services will start if I change them to run under the Local System account, but that didn't make them accessible on the network. I even tried removing the Routing and Remote Access Services feature, rebooting and reinstalling it, but the issue remains. Any ideas?

• Introducing the Oracle Parcel Service&ndash;Example/Reference Application

  - by Jeffrey West

  Over the last few weeks the product management team has been working on a webcast series that is airing in EMEA.  It is a 5-episode series where we talk about different features of WebLogic and show how to build applications that take advantage of these features.  Each session is focused at a different layer of the technology stack, and you can find the schedule below. The application we are building in this series is named the ‘Oracle Parcel Service’.  It is an example application and not a product of Oracle by any stretch of the imagination.  Over the next few weeks we will be finalizing the code and will be releasing it for you to check out.  For updates, request membership to the Oracle Parcel Service project on SampleCode.oracle.com: https://www.samplecode.oracle.com/sf/projects/oracle-parcel-svc/. Here are some of the key features that we are highlighting: JPA 2.0 (new in WebLogic 10.3.4) with EclipseLink Coherence TopLink Grid Level 2 cache for JPA JAX-RS (new in WebLogic 10.3.4) 1.0 for RESTful services Lightweight JQuery Web UI for consuming RESTful services JSF 2.0 (new in WebLogic 10.3.4) utilizing PrimeFaces EJB 3.0 Spring-WS Web Services JAX-WS Web Services Spring MDP’s for Event Driven Architectures Java MDB’s for Event Driven Architectures Partitioned Distributed Topics for Event Driven Architectures   Accessing the Code on SampleCode.Oracle.com You will need to log in using your Oracle.com username and password.  If you have not created an account, you will need to do so.  It’s a simple one-page form and we don’t bother you with too many emails.   Please join the project to be kept up to date on changes to the code and new projects.  Joining the project is not required, but very much appreciated. Once you have signed in you should see an icon for accessing the Source Code via Subversion.  You can also download a zip file containing the code.

• Identity Propagation for Web Service - 11g

  - by Prakash Yamuna

  I came across this post from Beimond on how to do identity propagation using OWSM.As I have mentioned in the past here, here and here - Beimond has a number of excellent posts on OWSM. However I found one part of his comment puzzling. I quote: "OWSM allows you to pass on the identity of the authenticated user to your OWSM protected web service ( thanks to OPSS ), this username can then be used by your service. This will work on one or between different WebLogic domains. Off course when you don't want to use OWSM you can always use Oracle Access Manager OAM which can do the same." The sentence in red highlights the issue i find puzzling. In fact I just discussed this particular topic recently here. So let me try and clarify on a few points: a) OAM is used for Web SSO. b) OWSM is used for securing Web Services. You cannot do identity propagation using OAM for Web Services. c) You use SAML to do identity propagation across Web Services. OAM also supports SAML - but that is the browser profile of SAML relevant in the context of Web SSO and is not related to the SAML Token Profile defined as part of the WS-Security spec.

• Windows Service with Logon a user

  - by David.Chu.ca

  I have a service running in a box with Windows XP and a box of Server (2003). There is one service running in autmactic mode. If I set the log on with a local user, the service will stop running if the user logs off the account from the Windows? In other words, in order to keep the service running, have I to keep the user as login mode? I understand that the service can be set as local system which will not need any one to login as long as the box is powered on. However, the service I need to run has to be running as a local user with the required permissions. The problem I have right now is that the box may reboot itself. If that happens, no one is logged in yet until some one has to log in as the required user. I want to make sure if the required user has to be as a log on user first. If that's the case, any suggestion to deal with unexpected reboot issue?

• How to use the unit of work and repository patterns in a service oriented enviroment

  - by A. Karimi

  I've created an application framework using the unit of work and repository patterns for it's data layer. Data consumer layers such as presentation depend on the data layer design. For example a CRUD abstract form has a dependency to a repository (IRepository). This architecture works like a charm in client/server environments (Ex. a WPF application and a SQL Server). But I'm looking for a good pattern to change or reuse this architecture for a service oriented environment. Of course I have some ideas: Idea 1: The "Adapter" design pattern Keep the current architecture and create a new unit of work and repository implementation which can work with a service instead of the ORM. Data layer consumers are loosely coupled to the data layer so it's possible but the problem is about the unit of work; I have to create a context which tracks the objects state at the client side and sends the changes to the server side on calling the "Commit" (Something that I think the RIA has done for Silverlight). Here the diagram: ----------- CLIENT----------- | ------------------ SERVER ---------------------- [ UI ] -> [ UoW/Repository ] ---> [ Web Services ] -> [ UoW/Repository ] -> [DB] Idea 2: Add another layer Add another layer (let say "local services" or "data provider"), then put it between the data layer (unit of work and repository) and the data consumer layers (like UI). Then I have to rewrite the consumer classes (CRUD and other classes which are dependent to IRepository) to depend on another interface. And the diagram: ----------------- CLIENT ------------------ | ------------------- SERVER --------------------- [ UI ] -> [ Local Services/Data Provider ] ---> [ Web Services ] -> [ UoW/Repository ] -> [DB] Please note that I have the local services layer on the current architecture but it doesn't expose the data layer functionality. In another word the UI layer can communicate with both of the data and local services layers whereas the local services layer also uses the data layer. | | | | | | | | ---> | Local Services | ---> | | | UI | | | | Data | | | | | | | ----------------------------> | |

• Engineering as a Service

  - by jgelhaus

  Oracle Exadata Database Machine is known for great compute performance, and over the past few years, it has also become known as a great platform for any type of Oracle Database workload, from data warehousing to online transaction processing (OLTP). But now organizations are turning to Oracle Exadata for business efficiencies and private cloud solutions—for consolidation and database as a service (DBaaS). University of Minnesota For an inside look at how DBaaS is working in the real world, it’s worth checking into the University of Minnesota’s database hotel.  With more than 50,000 students, the University of Minnesota in Minneapolis is one of the largest universities in the United States. The university’s centralized IT group not only has to support all those students but also must provide support and services to more than 40 departments and colleges within the university. They have two Exadata Database Machine X2-2 half-rack systems from Oracle, with four database nodes each and roughly 30 terabytes of usable disk space for each of the Oracle Exadata systems. The university is using Oracle Real Application Clusters (Oracle RAC) for high availability and the Data Guard feature of Oracle Database, Enterprise Edition, for disaster recovery capabilities. The deployment has been live in production since May 2011. Overhead Door When it comes to overhead, revolving, sliding, or other specialty residential and commercial doors, Overhead Door is the worldwide leader.
