IC92570: WMQ 5.3 FOR HP-NSS - MULTIPLE CLUSTER RECIEVER CHANNELS OR LONG RUNNING CLUSRCVR CHANNELS CAUSE METADATA FDC'S

WebSphere MQ for HP NonStop Server V5.3.1 fix pack 5.3.1.10

APAR status

• Closed as program error.

Error description

• If there are multiple cluster receiver channels or long
  running (more than 30 days) cluster receiver channels that
  are not in active use, the following FDC's may be generated
  from the slave repository managers at hourly intervals.

Local fix

Problem summary

• The cluster metadata implementation did not support having
  multiple cluster receiver channels for the same cluster on a
  queue manager.  Depending on configuration, this scenario
  resulted in multiple FDCs from the slave repository managers
  repeated every hour, starting with the first subscription
  refresh time following the queue manager startup.
  

Problem conclusion

• Change the slave cluster cache maintenance processing to remove
  the order dependency on the cluster queue manager objects
  referring to the same queue manager.
  

Temporary fix

• Restarting the queue manager will resolve the repeated FDCs
  until the next subscription refresh interval.
