Autorun WebDynpro Application after J2EE Server Restart

Hi All
I have developed an application which registers the event capturer for KM in webdynpro.This application doesnot have any UI output.
I need to run this application after every J2EE server restart.
I changed the portalapp.xml and added startup = true property, but of no use.
Is there any way to do this ?
Points will be rewarded for helpful answers.

You should create a portal service and set startup = true in portalapp.xml

  • How to disable autostart (application) when managed server restart ?

    Hi Ppl,
    How to disable autostart (application) when managed server restart ?
    I want some of the applications to remain not started. In WebSPhere, we have an option disable auto start for applications.
    I don't find in weblogic.
    Thanks

    Hi,
    I agree with Faisal. When you shutdown your WL server while the application is running, the thing is when you start your server again, it would automatically start the application with it. Now if the application was down when you shutdown the server, it _the application_ won't start with the server.
    So it depends on the application last state, when you start your server.

  • JDBC Connection pool recovery after DB server restart

  • Web Dynpro Application Deployment need server restart?

    Hi Everyone,
    When deploying Web Dynpro application on production environment, do we need to restart the sap portal system and server?
    I have this issue that when ever we deployed new develop Web Dynpro application with new Abap Function module we need to restart our Enterprise portal production server. Is this really necessary. Is there other way to deploy Web Dynpro application with new Abap function module without restarting the server.
    Please help,
    Michael Mondelo

    Hi michel,
    for example , assume you imported a RFC bapi_flights from r/3 to webdynpro dc , and both rfc requests and webdynpro application is deployed to the development server and then moved to quality server.
    now you have done some changes in the rfc bapi_flights i  mean change in the structure .
    case 1 : now with out reimporting the change to webdynpro application and you move the request to the quality r/3, your application dumps . because the structure change is not incorporated at your webdynpro DC.
    case 2 : you have re imported the rfc incorporating the changes to the web dynpro applicaiton dc, now with out moving the structure changes request to the quality r/3 and you deploy the webdynpro Dc having the changes to your quality EP , still the applicaiton dumps because your appliction refers to the rfc with out structure change in quality r/3.
    case 3 : you have moved the abap request having the strucutre change and also the webdynpro development component where the changes are also incorporated , now on moving both , your application might dump , because the meta data cache might have been not updated with the new structure change in the quality ep server. so you have invalidate the cache in the JCos you have used to import the rfc. or else on restarting the EP server , the new structure change will be updated in the server.
    most of the cases  Invalidation of cache works and in some cases you have restart the server fo the changes to update.

  • Best Practice to troubleshoot a Crawler Issue after SQL Server restarts

    Hi Everyone
    I am after some general advice or a suggested place to start when troubleshooting crawler issues after an unplanned, out-of-sequence server restart.
    Specifically, the SQL Database in the SharePoint 2010 farm. Better yet, is there a standard practice way of resolving such issues?<o:p></o:p>
    So far articles I have found suggest options from reviewing the crawl logs, creating a new crawl component, right through to using fiddler to monitor the crawler.
    Are these sufficient places to start / methodologies to follow, what else should be considered?
    Any advice greatly appreciated.
    Thanks,
    Mike

    Well, as I said before, there are lots of different potential issues & resolutions for crawlers.  It really depends on the issue.  I would say that the base troubleshooting steps start the same no matter which service/feature you are looking
    at.  So, I'll try to keep this sort of generic, but beyond finding the details of the problem, the SOP or process will vary greatly based on what the error is.  I hope this helps, and sorry if it's not specific enough.
    1 - check the ULS logs
    2 - check the windows application logs
    3 - verify related services are running (get-spserviceinstance), possibly stop/start them to reprovision the instance on the affected server
    4 - clear the config cache (this alone will clear about 30% of your basic problems)
    6 - verify disk space & resource consumption on affected server (& SQL, SQL is always the potential to be the true "affected" server)
    7 - iisreset
    8 - verify connectivity between all servers in the farm and SP
    9 - verify requir3ed features activated
    10- check if any changes were made to environment recently (new hardware, updates to OS or apps, updates to GPOs, new solutions, etc)
    11- check if the issue is reproducible in another environment (only reliable if this is a similar environment, i.e. same patch level test farm or dr farm).  see if it occurs in other site collections within the web app, different web apps, different
    servers/browsers, etc, basically just try to nail down the scope of the problem
    There is a whole slew of thiings you could check from verifying certificates & perms, to rerunning psconfig, to checking registry keys, again I go back to it depends.  hopefully this can get you started though.  in the end ULS is where all
    the real info on the issue is going to be, so make sure you check there.  don't go in with tunnel vision either.  if you see other errors in ULS, check them out, they may or may not be related; SharePoint is an intricate product with way more moving
    parts than most systems.  fix the little quick ones that you know you can handle, this will help to keep the farm clean and healthy, as well as crossing them off the list of potential suspects for your root cause.

    Yes, I did that. I'm not all that happy about this as a solution either, but it's better than making multiple copies.
    We have since found out that his is a known bug and that it is fixed in some, but not all, deployments.

    Composites With WSDL Dependencies Fail To Deploy Following SOA Server Restart [ID 1272070.1]          
    Modified:Jul 19, 2012 Type:PROBLEM Status:MODERATED Priority:3                         
    In this Document
         Symptoms
         Cause
         Solution
         References
    This document is being delivered to you via Oracle Support's Rapid Visibility (RaV) process and therefore has not been subject to an independent technical review.
    Applies to:
    Oracle SOA Platform - Version 11.1.1.3.0 and later
    Information in this document applies to any platform.
    Symptoms
    A SOA Project has an external reference to a Web Service or a reference to another Composite.
    When the SOA Server is started, the Composite is trying to access the WSDL of it's referenced Web Service in order to load data structures. If SOA can not find the WSDL then the Composite fails to load/deploy.
    Once this happens the Composite can not be started, or shutdown, from Enterprise Manager Fusion Middleware Control Application.
    Related Error Messages:

Finally, validate the HTTP proxy settings for the server.]
    javax.wsdl.WSDLException: WSDLException: faultCode=INVALID_WSDL: Error reading import of oramds
    Cause
    When SOA Server is restarting the Composite can not access the WSDL of it's referenced Web Service (it is not available).
    In the first scenario there are two Composites on the same server: CompositeA and CompositeB.
    In SOA Suite 11g there is no possibility to specify the load order for the composites. If CompositeA references CompositeB and if CompositeA is firstly loaded then it can not access the WSDL from CompositeB and the issue occurs.
    In the second situation there is one Composite on the server (CompositeA) which references an external WebService (ExternalWS). If the ExternalWS is not available when the SOA Server is starting then this issue occurs.
    Solution
    Solution 1
    Redeploy the affected Composite into the SOA Server.
    You can do that but it is not advisable in a production environment and in a development environment it will take a lot of time to redeploy the composite manually
    Solution 2
    Copy the abstract WSDL locally into the project.
    This is documented in these articles in our Knowledge base:
    •     Document:1155033.1 Node Restart Cause Composites To Become Unavailable. Response: '503: Service Unavailable'
    •     Document:1151973.1 Boot Order Of The Composites Upon Soa Suite Restart
    Steps:
    o     a. Copy and use the WSDL file in the Project
    o     b. Edit the WebService Adapter
    o     c. Change the "WSDL URL" to point to the WSDL copied into the project
    o     d. Redeploy the Project
    o     e. Make this configuration with all the Projects that have a references with other Web Services
    Solution 3
    Use shared artifacts in Metadata Service (MDS). A WSDL used by more than one composite is a shared artifact per definition. If the WSDL structure is changed (that is not happening frequently in a production environment), you will normally deploy a composite with a new version because overwriting it will break your production environment. Moreover, in a development environment you will need a proper process in place where different developers access the same artifacts within MDS. In addition, when you use external WSDLs (owned by third parties), you will have a proper process/agreement in place to be notified about modifications affecting your applications.
    1.     In order to use shared artifacts a MDS connection must be configured in jDeveloper:
    http://download.oracle.com/docs/cd/E14571_01/integration.1111/e10224/sca_lifecycle.htm#SOASE85488
    2.     Deploy the shared artifacts:
    o     a. Create a JAR profile and include the artifacts to share
    o     b. Create a SOA bundle that includes the JAR profile
    o     c. Deploy the SOA bundle to the application server
    http://download.oracle.com/docs/cd/E14571_01/integration.1111/e10224/sca_lifecycle.htm#SOASE85472
    If the shared artifacts (WSDLs) needed are from other composites this step can be skipped
    3.     Create a new WebService
    o     a. When completing the "WSDL URL" click on "Find existing WSDL's"
    o     b. Select "Resource Palette"
    o     c. Go to the SOA-MDS
    o     d. Select a WSDL from a Composite or the one deployed at step 2.
    Known Restriction 1
    The port and the location for the WSDL reference is not completed automatically by jDeveloper in the composite.xml file. This information must be inserted manually. In Bug:10287325 is raised this issue and it is available for SOA 11gPS2+.
    Known Restriction 2
    Another issue regarding MDS caching is raised in Bug:10218147 - the MDS cache is not refreshed when an artifact is deployed or deleted.
    In order to refresh this cache the server must be restarted. This Bug resolves the issue but in a production environment the server restart will be the preferred option. The reason for that is because in a production environment you never deploy single composites under the same version after artifacts (WSDLs) have been modified.
    The fix for the Bug:10218147 can be an acceptable solution in development environment where redeployment would be quicker than restarting the server.
    Bug:10218147 is available for SOA 11gPS2+.

    Solution 4
    The last solution is to use an UDDI (Universal Description Discovery and Integration).
    Oracle recommends Oracle Service Registry 11g (OSR). The advantage is that you can use OSR and SOA Suite in a Shared WebLogic Domain.

    Abstract: WHEN SOA SERVER IS RESTARTED, SOME SOA COMPOSITES COULD NOT LOAD/BE DEPLOYED
    Detailed Problem Description
    ====================
    When a SOA composite get dependencies with other SOA composites located on the same server, if the dependency is still not loaded, the SOA composite will not be loaded, and there is no possibilities for Entreprise Manager console to restart it (EM crash). The only way to make it working is to redeployed the SOA composite from jDeveloper that is not acceptable in a production environment.
    The composite that has the issue cannot be start-up or shut-down, although the Enterprise Manager do not show any errors with it.

  • Start deployed applications when J2EE Server starts

    Hi experts,
    This is my problem.
    I've updated my Netweaver 04s Developer Workplace from SPS1 to SPS10.
    The problem I have is that when I start my J2EE Server via MMC, the applications (j2ee,ear,webdynpro,...) I deployed don't start.
    If in my Visual Administrator I go to server->services->deploy most of them are not started. I can start them manually, but that's not a solution...
    I suppose there are any possibities to set this applications to start when the server is started.
    Any ideas?
    Thanks a lot.
    Alberto.

    Hi Alberto
    If you can start the services manually w/o problems, then maybe you can try to change the startup mode to 'always' so that the service is started automatically. You should be able to check this via Configtool. Switch to the 'configuration editor' mode and go to cluster_data -> server -> cfg -> services. Look for the service and make click on the propertysheet. Usually you can modify the startup mode there.
    I hope this helps.

  • JMS Application on J2EE server

    Hi,
    How can I run a simple PTP client-server application of JMS on windows platform? I am using a machine running windows 98, on which I have installed JDK1.3 and J2SDKEE1.2.1. I use J2EE server to deploy EJBs and Servlets on localmachine. I want to use the same J2EE server (J2SDKEE1.2.1 for windows) for JMS applications also. Please help me.
    Paras.

    Sun's J2EE SDK 1.2.1 does not support JMS. In other words, it does not have a JMS provider.
    You need to use Sun's J2EE SDK 1.3 to use the reference implementation of JMS API.
    However, you could use JMS provider from other vendor and still use J2EE SDK 1.2.1 reference inplementation as your application server.

  • BPEL process instance doesn't restart execution after BPEL server restart

    I am using Oracle BPEL server 10.1.2 on Windows with the Oracle lite 10G dehydration datastore.
    I have a one BPEL process (proc1) that invokes another BPEL process (proc2) synchronously. proc1 also invokes proc3 (also a BPEL process, but probably doesn't matter) synchronoulsy in parallel with proc2.
    proc2 has a wait of ~30seconds in it. As soon as proc1 invokes proc2, I shutdown BPEL. Now, when I restart the BPEL server, proc2 instance finishes its execution. But, I don't see instances of proc1 and proc3 in the BPEL console.
    Here are my questions:
    1. If proc1 invokes proc2 and proc3 in parallel, shouldn't I see instances of proc2 and proc3 at the same time? I only see proc2 not even proc1.
    2. Why doesn't proc1 resume its execution after BPEL server is restarted?
    Any pointers appreciated.

    1. If proc1 invokes proc2 and proc3 in parallel, shouldn't I see instances of proc2 and proc3 at the same time? I only see proc2 not even proc1.

    Hello,
    If you put a server in your project and you put the servlet at auto-start your application will start automatically when the server will start.
    To do that you just have to use the element:
    <load-on-startup>1</load-on-startup>
    in the servlet tag.
    server.xml:
    <application name="foo" path="../applications/foo.ear" auto-start="true" />

  • Windows Time source resets after service/server restart

    We have two completely separate domains.  Our main domain has 4 DCs: the PDCe is looking to an outside source for its time source and the other 3 DCs are looking to the PDCe for their time source.  The second domain, our DMZ, is setup the exact
    same way.  The PDCe is looking to an outside source for time and the other 3 DCs are looking to the PDCe for their time.  If the Windows Time service is restarted or the server is restarted (during patching, for example), the time source changes
    from the outside address to "Local CMOS Clock".  From there, everything else will get thrown off.  And now that I think of it, they might also revert to "Local CMOS Clock" after the service is restarted.
    I configured the PDCe using the following command, which completes successfully:
    w32tm /config /manualpeerlist:0.pool.ntp.org /syncfromflags:manual /reliable:yes /update
    I can then run w32tm /query /status and confirm the setting is correct, but if I do the recommended "net stop..." and "net start..." commands, it will revert to "Local
    CMOS Clock".  If I leave it alone and the server reboots, it will again revert.  This problem does not exist in our main domain.  I have the appropriate rights and I don't see anything in the event logs that would indicate what the problem
    is.  Thoughts?
    Chris

    so the first thing is that only your PDCe should be going out to the internet (or another reliable NTP source) to get the time and that's done with:
    w32tm /config /manualpeerlist:0.pool.ntp.org /syncfromflags:manual /reliable:yes /update
    all your other DCs then go to the PDCe to get their time and we do that with:
    w32tm /config /syncfromflags:domhier /update
    so when you say you tested it on "test DC", you need to ensure the right settings are being pushed relevant to that DC's role and I'm not really certain about this test environment you have here
    reading up on this, it all keeps going back to VMs doing time sync with the host, GPOs, scheduled tasks, or startup scripts
    you can check the Systems event logs though, there will be messages in there stating why it reverted back to local cmos. it might do it if it can't reach the time source you specified and that part is normal but you need to check the logs first. even a successful
    time sync message will help eliminate some of the causes
    I think unregistering/registering the service starting with your PDCe should make it stick, as long as it can actually communicate with "0.pool.ntp.org".  to verify this and to make sure UDP port 123 is open, run "w32tm /stripchart /computer:0.pool.ntp.org"
    - if you get a time chart then communication is fine but if you get something else then you may have problems hitting that source and it's reverting back to cmos.

    Hi all
    I need to pass the client reference in a java application(Not web app) to the bean,whether it is session, entity or message, and allow the bean to callback the client (by invoking the method located at the client side or another mean) when some event is happened. Is it possible? and how to do it?

    Look at the JMS API. Subscribing to a topic is the only way I have found to do what you want to do.
    Let me know if you find something else!

  • Webdynpro application automatic start after j2ee startup

    Hi ,
    Is there a way to automatically start any specific webdynpro applications after j2ee startup

    I guess you can write batch file for that.
    Example
    suppose you have a bat file which starts J2EE engine, startJ2EE.
    You can write a new bat file with following commands.
    startJ2EE.bat
    explorer http://<server>:<port>/webdynpro/<URL as application>
    Let me know if you need more help
