IC87122: AMQRRMFA PROCESS ENDS ABNORMALLY WITH REASON CODE MQRC_CONNECTION_BROKEN FOLLOWING QUEUE MANAGER QUIESCE

WebSphere MQ V7.5 Fix Pack 7.5.0.2
WebSphere MQ v7.5.0.2 Hypervisor for RHEL

APAR status

• Closed as program error.

Error description

• WebSphere MQ Repository Manager process experiences connection
  broken
  error and is unable to complete MQI calls during queue manager
  shutdown
  - possibly reporting error code 2195 (MQRC_UNEXPECTED_ERROR).
  This is followed by amqrrmfa process terminating abnormally.
  
  As an example the following errors may be seen in QMGR logs.
  
  AMQ9511: Messages cannot be put to a queue.
  
  EXPLANATION:
  The attempt to put messages to queue 'IBM.MQV75' on queue
  manager '' failed with reason code 2195.
  
  AMQ9447: Unable to backout repository manager changes.
  
  EXPLANATION:
  The repository manager tried to back out some internal
  operations
  but was unsuccessful. The reason code from the MQBACK call was
  2009.
  
  AMQ9409: Repository manager ended abnormally.
  
  EXPLANATION:
  The repository manager process ended abnormally. Termination of
  this process will cause the queue manager to terminate unless
  the tuning
  parameter TolerateRepositoryFailure has been set to 'TRUE'. If
  the queue
  manager does not terminate, further cluster management
  activity will not occur,
  this will effect the availability of cluster resources
  accessed or hosted by
  this queue manager
  

Local fix

• No workaround should be required - the repository process
  terminates and work in progress will be backed out on queue
  manager restart.ﾠ The error messages generated during
  termination can be safely ignored.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of WebSphere MQ for MultiPlatforms Version 7.5.0
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM SUMMARY:
  During queue manager quiesce on MQ 7.5, under some circumstances
  the Cluster Repository process (amqrrmfa) is not correctly
  notified to shutdown and attempts to continue processing as
  other components begin termination. When this occurs, amqrrmfa
  will eventually receive errors from MQI calls (such as 2195
  MQRC_UNEXPECTED_ERROR or 2009 MQRC_CONNECTION_BROKEN). Following
  these errors the amqrrmfa process issues error message AMQ9409
  and terminates.
  

Problem conclusion

• The WebSphere MQ product code has been corrected to ensure
  that the amqrrmfa process is notified on queue manager
  shutdown and quiesces cleanly.
