Weblogic JMS problem

          Hi,
          Weblogic throws the following exception when the JMS Server do not return messages.
          Any idea,the Weblogic server do not shutdown, but it increases the Queue Length
          Thanks in avance

There is no JMS in the stack trace. Perhaps this is an RMI or EJB
          invoke? Try the weblogic.developer.interest.rmi newsgroup. Try putting
          trace code in your "sendMessage(" method to see if it is getting called
          on the server, and see what it is attempting to return.

  • Problem in Interacting with Weblogic JMS through Informatica ETL server

    Hi All,
    We are trying to configure Informatica PowerCenter server to interact with JMS queues created on Weblogic 11gR1 server. We have copied the necessary

    I have checked that this class file exists in the above said location :- "weblogic/jms/common/DestinationImpl.class" within the wlfullclient.jar but still the
    code is not able to access the class. Similar error came initially while doing JNDI connection using "weblogic.jndi.WLInitialContextFactory" class but it vanished,
    when i explicitly named the jar file on classpth, instead of just the folder containing the jar file.
    To all the users/experts/moderators of Weblogic - Could you please help me understand why Weblogic is not able to look up subcontext 'common'
    for the class - "weblogic.jms.common.DestinationImpl" ??
    Thanks & Regards

    You are experiencing a NameNotFoundException, not ClassNotFoundException so it seems there is something wrong about the client connection code or WebLogic config.
    Can you share your client connection connection config/code?

  • WebLogic JMS high memory usage and frequent full GCs

    Hi Team,
                We have below set up in production (and all the lower environment).
    1. WLS: 10.3.6 (64 bit)
    2. Java: HP JDK 1.7.0.06 (64 bit)
    3. Two Manage server instances in cluster with one Migratable target
    4. one JMS server with Persistence store targeted to Migratable target
    5. Messages are persisted in DB
    6. about 37 distributed queues/topics are hosted on one JMS server
    7. .Net JMS clients and WebLogic JMS clients connect to respective JMS distributed Queues/topics to either produce message or consume.
    Since last month, we see that WebLogic Manage server hosting JMS server keeps on chewing memory "even with small (of the order of 28 messages in 4/5 days) load", GC indicates that objects are shifted from PSYoung space to ParOldGen during minor GCs but ParOldGen space keeps on filling up in smaller chunks. After x number of days (where x ranges from 5-7 days), even Full GC is not able to bring down memory significantly and that's when frequent full GCs start with long pauses making JMS highly unstable.
    We don't have JMS Quotas configured but I think something else going on as it is not high on load.  Any additional hints or troubleshooting steps is much appreciated?
    Here is first and last  GC log just to give an idea...

    Regards,

    Thanks Luz. I have been collecting gclogs and heap dumps (whenever app server is high on memory and frequent GCs with long pauses are seen). So far heap dumps haven't revealed anything specific (may be I am not able to read heap dumps properly ) but looking at GC confirms that app server is consuming allocated heap.I was following Oracle WebLogic server support Patter as you have indicated. I thought about opening a ticket with HP but on high level JVM is doing what is suppose to do i.e allocating memory space as needed and performing GC therefore didn't go that path.
    Any other suggestions that might be useful. One of the things I forgot to mention ( and I will add it to original message), that one of the .Net consumers is not asynchronously connecting to its queue (to consume messages) rather it is synchronously connects and then if it doesn't find messages it disconnects and process goes on every few seconds. I was reading somewhere that frequent JNDI look ups should be avoided. Can this cause memory issue if so then it is strange as this same set up has been there over a year and we never has problem then?
    Regards,

  • Oracle PL/SQL send/receive message in weblogic jms queue

    I am looking for a very simple way using oracle plsql to send and receive messages in a weblogic jms queues.
    Thanks

    Even i am looking for the same . Would be great if someone would help ..The jms setup has to be done in weblogic like the jms server, jms module, Jms connection factory , jms queue and then the jndi names . Now thw Problem here lies to me is that i really dont knw what should be the connection factory targets ,jndi names and where do i give the schema details as in the user name ,password , db name . Also if there is any explaination with eg on how to send /receive messages from a db trigger to jms queues .

  • Inconsistent message publishing times through weblogic JMS client

    Hi,
    We have a weblogic JMS application which we are deploying in a clustered weblogic enviornment. We are using distributed queues/topics with file store. We have both JMS cliient and server running on separate weblogic clusters. Most of the times it will take about 10 milli seconds to push the message into queue, but 1 in 50 messages takes about anywhere between 0.2 sec to 6 secs. Recently for three days it just took 10 msec for all the messages throught these three days and then started behaving erratically again. I am not able to really figure out why there is lot of deviation in the publishing times. When I monitor both my client and server through admin consiole, I don't see any stuck threads, heap size is normal, cpu load is normal, no problems with network. Please help me to figure out the root cause for abnormal publishing times.
    Regards
    Koti

    Could you check if there are JVM garbage collections during some the publishing times.
    In particular check if there are any full garbage collection occuring when you notice such a deviation in the publishing time.

  • Using Weblogic jms message id for unique id

    Hi All,
    We have a requirement to generate random unique id for each message processed by the application. We are planning to leverage weblogic jms message id for this purpose rather than building our own application logic for this purpose . Will there be any issue adopting this ? We think weblogic jms message id will be unique across the cluster as id is a hash of current timestamp + jms server name + wl server name + ?? .. is this correct ?
    TIA
    Atheek

    Hi Atheek,
    It depends on what are you planning to do with that id, as there are some gotchas on Weblogic's JMSMessageID generation.
    I guess the msg id could be considered statiscaly unique as Tom says, but the msg id will change during the livecycle of your message, surprise! (yea, the JMS spec allows the JMS server to modify the msg ids).
    So if you want to use that id to correlate messages id, or to group info related to one message, using JMSMessageID could be a problem.
    You can consider to generate a UUID, using Java 1.5 support (java.util.UUID) or a external library (JUG http://jug.safehaus.org for instance), and attach that id as a JMSCorrelationId or a user defined property.
    Hope this helps

  • Garbage added to log while sending message to Weblogic JMS topic

    Hi All,
    Was able to sucessfully send messages to Weblogic JMS topic and also able recieve them.
    But while sending the messages to topic loy of debug statements are printed to the standard output
    This is seen only in production and not in developement, and expecting it due config issue...
    Any ideas on this is greatly appriciatied.
    Thanks in advance !
    Cheers,
    Ambha

    Thanks for the replies,
    The problem is certainly not with logger settings...
    The statements which are getting printed are SSL debugging
    The following settings are used by the application which sends messages to the topic :
    Dssl.debug=true
    Dweblogic.StdoutDebugEnabled=true
    These settings are same in Dev, UAT, and Production. But why the debug statements are seen only
    in UAT and Production I am not sure...
    *<Some TIME IST> <Debug> <TLS> <000000> <......>*
    *<Some TIME IST> <Debug> <TLS> <000000> <......>*
    *<Some TIME IST> <Debug> <TLS> <000000> <......>*

  • CMT and using non-Weblogic JMS in a session bean

              I am writing a session bean which sends a JMS message using a non-weblogic JMS
              provider. This bean is marked for CMT and I want the JMS send to participate in
              this CMT as well. My understanding is that I should be able to do this by defining
              a <resource-ref> element in the ejb-jar.xml and a corresponding <resource-descriptor>
              element in the weblogic-ejb-jar.xml file. The bean would then use the <res-ref-name>
              defined under the <resource-ref> element to lookup the connection factory. What
              do I have to put in weblogic-ejb-jar.xml file to make sure that the connection
              factory specified in <res-ref-name> maps to a connection factory that is in a
              foreign JNDI provider (e.g. in the non-Weblogic JMS provider's JNDI) and not in
              Weblogic's JNDI?
              Thanks in advance for your help.
              

    It sounds like you're using Tibco JMS to receive messages from the MDB, and
              then to send out a message. WLS 7.0 will handle the transaction enlistment
              properly when it receives messages for the MDB, but you'll have to enlist
              the JMS provider yourself when you send the message, using the white paper
              that Tom pointed you to as a guide.
              In WLS 8.1, coming soon, we'll automatically enlist the provider in the
              transaction if you look it up using a "resource-ref" element in the EJB like
              you described. Today, you can use that element but no transaction
              enlistement is being done.

  • JMS error: weblogic.jms.frontend.FEConnectionFactoryImpl_1032_WLStub

    hi weblogic users,
    i have a problem in sending jms messages
    across two different weblogic host/domain.
    the configuration is:
    jms client:
    -JAX-WS webservice web app
    -deployed in WebLogic Server Version: 10.3.1.0
    -host: 192.168.30.133:7011
    -domain: ChSoaAdminServer1
    -can access server's console: http://192.168.1.22:6001/console
    server:
    -jms server, jms module, cf, queue configured
    with subdeployment targeted to the jmsserver
    -deployed in WebLogic Server Version: 10.3.2.0
    -host: 192.168.1.22:6001
    -domain: soa_domain
    -cannot access client's console: http://192.168.30.133:7011/console
    i use standard lookup method in my java client code:
    String settingJmsServer="t3://192.168.1.22:6001";
    String settingCF="jms/adminduk/cf";
    String settingQueue="jms/adminduk/queue/central";
    env=new Hashtable();
    env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
    env.put(Context.PROVIDER_URL, settingJmsServer);
    ctx = new InitialContext( env );
    System.out.println("-- Destination");
    ds = (Destination) ctx.lookup(settingQueue);
    System.out.println("-- ConnectionFactory");
    cf = (ConnectionFactory) ctx.lookup(settingCF);
    but it's getting exception
    when looking up the connection factory (look at the bottom of my post):
    ok now, how to solve this problem?
    -i tried to change the server to another host with WL 10.3.1.0 installed (so
    it's the same version with the client) and its ok (receiving messages)
    -i tried to deploy the WS client to the same host as the jms (WL 10.3.2.0), so no
    remote lookup needed (java lookup code adjusted), it's ok
    -based on the stack trace:
    "Could not find dynamically generated class:
    'weblogic.jms.frontend.FEConnectionFactoryImpl_1032_WLStub
    (class not found) ..."
    -does it mean do i've to use the same version of WL installed in the client side ??
    -is WL 10.3.2.0 compatible with WL 10.3.1.0 ?
    -is it possible to use a different version of weblogic (in the client/server)
    in using the jms feature ?
    -do the jms server must have access to client's port (7011) for it to work ?
    thanks,
    any info/hints/helps will be appreciated :)

    ---------- end error ---------

    1 - A class-not-found is an odd exception to get on a server. Did you perhaps try to add client-only jars to the server classpath? The server classpath is already setup properly to act as a client.
    2 - Its usually not a good practice to create contexts in client code (instead of simply using the Servlet context in your case), or to hard code URLs, dests, and CF references into the code. It works, but can be hard to maintain and inefficient.
    3 - See:

  • Connect from Weblogic JMS queue to SAP WAS JMS queue

    Hi,
    I am trying to setup a WLS 8.1 messaging bridge between a weblogic JMS queue and a SAP WAS JMS queue. I have configured a queue on both Weblogic and SAP WAS and I have set up the messaging bridge and bridge destintations in weblogic. However when weblogic tries to get the SAP initial context factory it fails with the error below.
    I have added the SAP Client jars to the weblogic system classpath, and in the weblogic startup script but it still fails. Has anyone connected from an external JMS queue to a SAP WAS JMS queue that could provide me with some guidence?
    <10/08/2006 08:23:45 AM WST> <Warning> <Connector> <BEA-190032> << Weblogic Mess

    Thanks

    Stoyan,
    Thanks for that.
    My problem ended up being a classpath problem. I referenced the directory of the SAP jars in the weblogic start up script. When I changed this to reference each jar individually it worked.
    I have a new issue now which may have something to do with security. The trace suggests it is logging on as the guest user, even though I entered my username and password in the Messaging bridge.

  • WebLogic JMS and MQ JMS Mix

              I am writing a bean that reads a message from MQ (using MQJMS) and then write it
              onto a WebLogic JMS ( something lika a bridge). However I don't want to use bridge.
              Question/Problem Statement:
              Once I include mq jms jar files in class path. Would that in conflict with WebLogic
              JMS. How do in my program I make sure that it is using the MQ or WLS JMS implementation.
              I can have InitialContext() setup for mq in File and for WebLogic it is WebLogic's
              Initial Context. Thats is the only thing that I can tell in the program.
              Basically, I am trying to see what will make it ( fully qualified JMS Objects
              or what) decide which implmenatation to use.
              Chris
              

    The WebLogic JMS and MQSeries JMS classes won't conflict. Each JMS provider
              provides different classes that implement the same interfaces, so you can
              have a whole bunch of providers in your classpath and things should be OK.
              Most code that's written to the JMS API (including the code inside WLS that
              receives messages for MDBs) gets the JMS "ConnectionFactory" via JNDI, and
              uses that to create the other objects. (It also has to look up the
              "Destination" objects from JNDI.) When you code to the JMS standard only,
              then the only thing that "tells" your program which provider is being used
              is the ConnectionFactory class that you create or get out of JNDI.
              Below is my usual plug for the white paper that helps explain some of this
              stuff:
              http://dev2dev.bea.com/resourcelibrary/whitepapers.jsp?highlight=whitepapers
              Look for "Using foreign JMS provdiesr with WLS".

  • Weblogic/jms/backend/BEMessageReference

    Hi ,
    I have a severe OOM problem in production as my servers are crashing very often.. I have 32 GB unix box and I have put -Xmx 3072 -Xms 3072 as MEM_ARGS for Managed1 and Managed3 ... eventhen I am getting OOM ...
    Can anybody suggest me best MEM_ARGS with -Xx:MaxPermsize for Admin ,Managed1 and Managed3 server instances...
    I have put Heap dump options analyzed the heap dump file showing 63% is weblogic/jms/backend/BEMessageReference.. Can anybody tell me whats the rootCause of this .
    using weblogic 8.1 sp6 and jdk 1.4.2_16 version.
    Thanks
    Sanjana

    Hi,
    What's most likely happening is that the application did not configure JMS quotas and/or flow control, plus its inserting messages faster than they can be processed. It may also be the case that JMS paging hasn't been configured. If so, then an examination of JMS statistics on the WebLogic console should help make the root cause obvious, and, since you're on 8.1, I'd recommend reading the old [ WebLogic JMS Performance Guide |  http://ftpna2.bea.com/pub/downloads/WebLogicJMSPerformanceGuide.pdf ] white-paper for ideas about how to address the issue.
    Tom
    PS. In the future, please post to the JMS newsgroup instead of the General newsgroup.

  • Weblogic 10.3 not suporting for MDB to connect remote Weblogic JMS server

    Hi,
    I have a problem with MDB deployed on Weblogic 10.3.It's simple MDB which is communicating with remote weblogic JMS server. I am getting below exception. could some one help how to resolve this issue.
    <Apr 14, 2009 11:28:52 AM PDT> <Warning> <EJB> <BEA-010061> <The Message-Driven EJB: ReceiverFromDocumentum is unable to con
    nect to the JMS destination: FMAContractOutboundQueue. The Error was:
    [EJB:011013]The Message-Driven EJB attempted to connect to the JMS connection factory with the JNDI name: FMAConnectionFacto
    ry. However, the object with the JNDI name: FMAConnectionFactory is not a JMS connection factory. NestedException Message is
    :weblogic.jms.client.JMSConnectionFactory cannot be cast to javax.jms.XAConnectionFactory>
    -Sreekanth

    I recall that this particular warning message is sometimes misleading about the root cause of the problem, an issue that I think has been fixed in a patch. The actual problem can be various:
    * The MDB is configured to be transactional, the connection factory exists, but the connection factory isn't configured to be "XA enabled". (I think this is the most likely problem).
    * The connection factory doesn't exist.
    * The object in JNDI with the specified connection factory name isn't actually a connection factory.
    * The dest object in JNDI with the specified name isn't actually a javax.jms.Destination
    Note that its unusual to configure the connection factory name for an MDB that consumes from WebLogic JMS. The default name iis usually sufficient unless custom tuning is required on the connection factory. See the MDB section of the EJB developer guide for more information.
