    which is connected to a WebSphere MQ z/OS Queue Sharing Group
    results in an exception of the following form, seen in the
    SystemOut.log file:
    
    ActivationSpe E   J2CA0138E: The Message Endpoint activation
    failed for ActivationSpec <MyActivationSpecName>
    (com.ibm.mq.connector.inbound.ActivationSpecImpl) and MDB

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the WebSphere MQ Resource Adapter
    who have Activation Specifications which connect to a z/OS Queue
    Sharing Group.
    
    This includes users of:
    
    - The WebSphere MQ V7.0 and V7.1 Resource Adapter.
    - The WebSphere Application Server V7 WebSphere MQ messaging
    provider.
    - The WebSphere Application Server V8 WebSphere MQ messaging
    provider.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows) +Java +Java zOS
    ****************************************************************
    PROBLEM SUMMARY:
    The WebSphere MQ Resource Adapter records the unique identifier
    of the queue manager it has connected to, and upon reconnection
    the identifier is checked to ensure the same queue manager has
    been reconnected to.
    
    For z/OS queue sharing groups, it is possible that upon
    reconnection a different queue manager from the group is
    connected to, which results in an error is reported - despite
    this being a valid reconnection.
    

Problem conclusion

  • The WebSphere MQ Resource Adapter has been updated to allow it
    to reconnect to a different queue manager when a queue sharing
    group is being connected to.
