Error description

  • The NonStop system have 2 CPU system and all MQ primary
    processes started on CPU1.
    The putting application put messages into the queue and
    MQRC_BACKED_OUT was returned when the backup CPU (CPU0) was
    went down.
    The putting application reconnected to the queue manager and
    put messages.
    Then getting application got messages from the queue.
    After RC 2033 MQRC_NO_MSG_AVAILABLE was returned, the queue
    status still showed CURDEPTH(1).
    

Local fix

Problem summary

  •  In case of a "MQRC_BACKED_OUT" (2003) failure
    situation when putting non persistent messages without syncpoint
    and outside of transactions, the failing put will still be
    counted towards the queue depth statistics for this queue.
    

Problem conclusion

  •  The product has been changed to handle
    such situations and decrement the queue depth statistics
    accordingly.
    

Temporary fix
