IT03205: DEFXMITQ can be set to SYSTEM.CLUSTER.TRANSMIT.QUEUE using the crtmqm -d switch, but this should not be allowed

Fix Pack 8.0.0.1 for WebSphere MQ V8.0

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.

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.
