  • Closed as program error.

Error description

  • When using the WebSphere MQ Resource Adapter inside a J2EE 1.4
    compliant application server, if multiple message-driven beans
    are configured to listen on destinations hosted by the same
    queue manager, only one of the beans will reconnect if either
    the connection to the queue manager is broker, or the queue
    manager is restarted. All of the other message-driven beans
    will fail to reconnect.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects any message-driven beans that use the
    WebSphere MQ Resource Adapter to connect to a queue manager.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows) +Java
    ****************************************************************
    PROBLEM SUMMARY:
    The WebSphere MQ Resource Adapter contains a list of Message
    Endpoints (message-driven bean references) that will be
    notified if the connection to the queue manager is broken.
    However, only the first Message Endpoint was being added to the
    list. All of the others were being ignored.
    

Problem conclusion

  • The Resource Adapter has been modified to add references for
    all of the message-driven beans into the list of Message
    Endpoints. This ensures that all of the message-driven beans
    are scheduled to restart when the connection to the queue
    manager is broken.
