Resource Adapters in clustered env..

Hi All,
          Can anybody throw some light on how resource adapters will behave in
          weblogic clustered environment ?
          thanks and regards

This question falls outside of JMS-land. Perhaps you can try the EJB newsgroup?
          Just in case your trying to use an adapter to receive JMS messages: There's no need to use resource adapters for WebLogic MDBs driven by JMS destinations.

  • HWF UI work list not loading in BPM worklist page (on clustered env)

    hello - Please reply directly as I am not on this alias.
    My SOA project (BPEL+HWF) is successfully deployed on the clustered env successfully.
    My BPEL process runs fine. But my HWF_UI taskflow fails to load on the browser (IE and Firefox, same error)
    I can see the composite & UI ear(enterprise app) on EMConsole & AdminConsole, and all configs/ settings looks ok.
    During execution, the work item pops up on the BPM worklist, but when I click on the work-item, the HWF_UI component is not loading....
    Not Found
    The requested URL /workflow/DOO_Simulation_ProjectUI/faces/adf.task-flow was not found.
    How do I overcome this or get some meaningfull error info.? The log files donot tell much..
    Caused By: oracle.adf.controller.ControllerException: ADFC-12002: The ADF Controller is unable to pop the top-level ADF unbounded task flow from the page flow stack.
    at oracle.adfinternal.controller.state.PageFlowStack.pop(PageFlowStack.java:184)
    Another question:
    How do I test if my HWF task flow component (UI) is installed & working / executing properly? any error logs/ error level settings?
    Edited by: ssondur on Apr 5, 2013 4:17 PM

    It is deploying correctly, the worklist app displays my instance. Btu when I click on my worklist item, the UI does not load or display. Below is the browser error and logfile error messages.

  • Database Poller issues in Clustered env

    Hi,
    I am running Oracle BPEL 10.1.3.4 on top of Weblogic version 9.x in a clustered env. I created a simple database poller BPEL process (for target table in Oracle database) with below parameters:
    Max Raise Size: 1
    Max Transaction Size: 2
    Polling Interval:30
    Distributed Polling is enabled
    All other BPEL engine and domain level parameters have default values.
    In my clustered env two instances of database poller BPEL process are running on diff nodes. Now I populated my table with 1000 records in one go. According to parameters I expect:
    - In each polling interval max 2 record will be processed by database poller BPEL process running on single node. And there will be 2 instances of this bpel process as max raise size is 1. Same I expect for database poller BPEL process running on another node. So overall 4 records should be processed in each polling interval and 4 instances of BPEL processes should be visible in BPEL console. But in actual its always 2.
    Is I am missing something here? Won't the load balancer distributes records to BPEL processes on both nodes equally?
    Also then I raise Max transaction size to higher value e.g. 20. But in this case after processing nearly 1/3 rd of records, the BPEL process stopped picking up any further records. Is there any known issue where Adapter stops picking any further database records if transaction size limit is higher?
    thanks

    Hi Ankit,
    I have Oracle BPEL env11.1.1.2.0 clustered over 2 nodes.
    I am facing a similar issue. In my scenario I have Bpel (with DB poller) and its deployed on the cluster. And I am connected to DB via Multi data source (MDS-1) with only one datasource (DS-1) configured in it.
    So whenever I update the table which is being polled, in some cases I have TWO instances and in some cases I have ONE Instance running. My requirement is to have only one instance running every time the DB poller is initiatied.
    Kindly help me out.
    Thank You
    Best Regards

  • Resource.adapters attribute

    The IDM documentation states you must add your new custom resource to the waveset.properties file in $WSHOME/config. It states it must be placed under the resource.adapters entry or it will not be recognized.
    However, when I look through the Waveset.properties file, the only mention of "resource.adapters" is in a comment area for ResourceManagerVersion:
    # ResourceManagerVersion
    # Specifies the version of the Resource Manager to be used. The
    # Resource Manager controls the list of available resources.
    # Additional resources are specified in the resource.adapters
    # attribute above.
    However, there is NO resource.adapters attribute in this file. Is there a sample of how this attribute needs to be formatted and the syntax one should use?

  • Resource Adapters for email drivers...

    sometimes it picks up all old files from FTP directoryIf it is picking up the same files, probably it is not being able to calculate the modification dates.
    That can be a configuration problem, take a look at this:

  • Serialization Exception with a MailSession in a WLS 9.1 Clusterred Env.

    I have a WLS 9.1 cluster of 2 machines. My EJB's are targetted to both
    machines in the cluster, and I have a single WLS MailSession that is
    targetted to both machines in the cluster.
    One of the EJB's is responsible for sending emails. Every so often I get a
    NotSerializableException when the EJB looksup the mail session. After some
    diagnosis it appears that every once in a while the JNDI lookup for the mail
    session returns the MailSession from the opposite machine in the cluster:
    IE: the EJB running on server 1, gets the MailSession from server 2, and
    vice-versa.
    When the same EJB is running in a non clustered env, there are no problems.
    And the problem in the cluster is intermittent - sometimes the lookup
    succeeds and the EJB gets a handle to the local MailSession object, and
    sometimes it fails.
    Has anyone else experienced this problem? Is this a known problem? If so,
    are there any patches for it?
    Thanks,
    Brett

  • Open script play doesnt work in the clustered env

    We have Clustered Webcenter env. Here, we record our flow in the open script. If we play back as the recorded user, it works fine.
    However if we randomize the users it fails with the following two errors :
    1.Failed to solve variable web.input.wccontextURL_1 using path .//INPUT[@name='wc.contextURL']/@value
    2.Failed to solve variable afrloop3
    ** This issue is not seen, if we done through browser multiple times with different users.
    **However if we run this in a non-clustered environemnt, it works fine.
    **Also if we bring down one of the managed servers, the script works fine.
    Can you plesae help?

    I don't think play() is the problem.  That error occurs when an object the code is trying to target does not exist as far as the code is concerned.  If that is the only code you have in the file, then you have a problem with "b2" not being seen by the code in frame 1.
    Did you assign "b2" as the instance name via the Properties panel, or is that the library name of the button?
    Are both the code and the button in frame 1 of the same timeline?  The way you said it can give the impression the code is in frame 1 inside the button.

  • Cluster Resource Failed in Clustered Role

    Hello All.
    We’re running our VMs on the Cluster of Hyper-V hosts of Windows Server 2012 R2.

    “Cluster resource 'Virtual Machine VM123' of type 'Virtual Machine' in clustered role 'VM123' failed.
    Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart

  • JNDI name for resource adapters

    When I look up a connection factory via the initial context, which JNDI name should I be using? How do I know which namespace my JCA resource adapter is in?
    I have registered the standalone JCA resource adapter via the command
    C:\OraHome_2\dcm\bin>dcmctl deployApplication -f my.rar -a my_jca
    Can I access it like this from my EJB?
    Context initialContext = new InitialContext();
    jcaConnectionFactory = (ConnectionFactory)initialContext.lookup("my_jca");
    or does it have to be java:comp/env?
    The default oc4j-ra.xml that was generated by dcmctl looks like this:
    <?xml version="1.0"?>
    <!DOCTYPE oc4j-connector-factories PUBLIC "-//Oracle//DTD Oracle Connector 9.04//EN" "http://xmlns.oracle.com/ias/dtds/oc4j-connector-factories-9_04.dtd">
    <oc4j-connector-factories>
    <connector-factory location="" connector-name="my_jca">
    </connector-factory>
    </oc4j-connector-factories>

    What is the correct way of looking up a resource adapter from another resource adpater? The JNDI name of my resource adapter is "StorageFactory" and I am doing a lookup like:
              Context ctx = new InitialContext();
              ctx.lookup("StorageFactory")
              Is this a correct way to lookup?

  • Uploading & Processing of CSV file  fails in clustered env.

              It doesn't make sense? Who is replicating the file? How long does it
