    * PROBLEM DESCRIPTION:                                         *
    * Summary details in output of DMPMQMSG may incorrectly show   *
    * negative values for messages and bytes read and written,     *
    * when processing a large amount of data from a queue.         *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * N/A                                                          *
    ****************************************************************
    The number of messages and bytes read and written using the
    QLOAD and QUNLOAD features of DMPMQMSG utility may incorrectly
    display negative values, when used with large queues. This is
    due to the values incorrectly being displayed as signed integer
    values, resulting in the behaviour seen.
    

Problem conclusion

  • The problem summary output for these fields has been corrected
    to ensure large values are correctly handled, and positive
    values are returned in this case.
