Error description

  • When using DataPower to connect to WAS 8.5.5.3 JMS server (via

    enabled, the client side (DataPower) gets unexpected response
    from server side.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  WebSphere Application Server users of the   *
    *                  default messaging provider (SIB) who        *
    *                  require strict message ordering.            *
    ****************************************************************
    * PROBLEM DESCRIPTION: Multiple consumers may be created       *
    *                      concurrently resulting in messages      *
    *                      being delivered out of order.           *
    ****************************************************************
    * RECOMMENDATION:  apply the apar fix if strict message        *
    *                  ordering is required.                       *
    ****************************************************************
    When multiple consumers are used to request messages there
    is a possibility, in complex scenarions, that two concurrent
    consumers may be created depsite strict message ordering
    having been specified.  This can occur when the implementation
    erroneously allows a new consumer to be created despite the
    presence of a message locked under a transaction by an existing
    consumer.  This can result in out of order delivery.
    

Problem conclusion

  • The implementation was modified so that multiple consumers
    will not be created concurrently when using strict message
    ordering.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.5.15 and 9.0.0.11.  Please refer to the
