IT08589: WebSphere MQ cluster queues become invisible to other queue managers where multiple clusters are in use

APAR status

• Closed as program error.

Error description

• WebSphere MQ V6 or V7 queues become "missing" from clusters.
  
  Application calls to MQOPEN (sometimes MQPUT1, MQPUT) suffer
  queue name lookup errors (Examples: 2085, 2082) when they try to
  access the affected cluster queues.
  

Local fix

• Issue refresh cluster command.
  

Problem summary

• WebSphere MQ V6 or V7 queues become "missing" from clusters.
  Application calls to MQOPEN (sometimes MQPUT1, MQPUT) suffer
  queue name lookup errors (Examples: 2085, 2082) when they
  try to access the affected cluster queues.
  

Problem conclusion

•  Backported IV15374
  The WebSphere MQ product code has been corrected such that, in
  the scenario above, no new subscription is made.  Instead the MQ
  code will now leave such an activity to be fully performed in
  every cluster, at a later moment, if and when an application
  later wants to use the queue.
  

Temporary fix

• Issue refresh cluster command.
