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.
