Error description

  • The MQ queue manager command server (amqpcsea) process does not
    report error message to the queue manager error log whenever
    MQRC_Q_FULL (2053) condition is encountered while handling
    remote administration requests.
    for example:
    In a client server setup if we issue runmqsc commands on the
    queue manager remotely from client
    runmqsc -e -w 30 -c TESTQM
    dis ql(*)
    AMQ8409: Display Queue details.
       QUEUE(AMQ.5B863C1A026B6920)             TYPE(QLOCAL)
    AMQ8409: Display Queue details.
       QUEUE(Q1)                               TYPE(QLOCAL)
       ...
    AMQ8409: Display Queue details.
       QUEUE(SYSTEM.ADMIN.STATISTICS.QUEUE)    TYPE(QLOCAL)
    AMQ8101: WebSphere MQ error (805) has occurred.
    AMQ8416: MQSC timed out waiting for a response from the command
    server
    
    In the above case the command server process encounters
    MQRC_QUEUE_FULL condition and hence dis ql(*) may have not
    listed all the local queues. However MQRC_QUEUE_FULL condition
    is not reported in the error logs. There is no other means for
    the command server to report the failure to the client which
    made the request.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    MQ users using remote administration with large number of system
    objects on the queue manager can be affected.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The MQ queue manager command server process responds to PCF
    requests via a reply-to queue specified on the request by the
    requesting application. If this queue was put inhibited, full,
    or became full before all responses were sent to the requesting
    application, there was no mechanism to provide feedback that
    this was the reason for the failure.
    

Problem conclusion

  • The command server (process) has been modified so that
    MQRC_Q_FULL or MQRC_PUT_INHIBITED error conditions on the
    reply-to queue when responding to a PCF request are reported in
    the queue manager's error log.
