APAR status

  • Closed as program error.

Error description

  • If the user sets the queue manager's DEFXMITQ attribute to
    SYSTEM.CLUSTER.TRANSMIT.QUEUE, then messages can be placed on
    that transmission queue with invalid CorrelId values and
    therefore these messages will never be acted upon by any CLUSSDR
    channel, and will remain on the SYSTEM.CLUSTER.TRANSMIT.QUEUE
    forever.
    
    In APAR IV01112 additional checks were added to the queue
    manager command processing routines (example: runmqsc) to
    disallow setting the value "SYSTEM.CLUSTER.TRANSMIT.QUEUE" for
    the DEFXMITQ attribute for the queue manager object, and write
    an error message.
    
    There is an additional way to set a value for DEFXMITQ, which is
    to supply the -d switch on the crtmqm command. A similar
    validity check was not applied to crtmqm under IV01112. A
    validity check must be added to crtmqm to make it consistent
    with the other ways of setting DEFXMITQ.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who mistakenly try to set the DEFXMITQ attribute for the
    queue manager object to the value SYSTEM.CLUSTER.TRANSMIT.QUEUE.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    It is not valid to set the DEFXMITQ for the queue manager to the
    value SYSTEM.CLUSTER.TRANSMIT.QUEUE, but the WebSphere MQ
    product code was allowing this value to be set via the crtmqm -d
    switch.
    

Problem conclusion

  • Additional checks have been added to the WebSphere MQ product
    during crtmqm to disallow setting the value
    "SYSTEM.CLUSTER.TRANSMIT.QUEUE" for the DEFXMITQ attribute for
    the queue manager object.
