Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of Queue Manager Clusters
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    During the normal hour maintenance of the cluster repository
    process (amqrrmfa), the existence of internal subscription are
    checked for queue and queue manager objects in the local queue
    manager view of the cluster configuration. If a queue manager
    record is found not to have subscriptions in the appropriate
    cluster(s) it is a member of, an FDC with probe RM702021
    (Missing Subscription) should be generated.
    
    However, if the queue manger record had a named cluster which
    the local queue manager was not aware of (because it is not a
    full repository for the cluster, nor is it a partial repository
    either), then the generated FDC was misleading as there should
    not have been any subscriptions.
    

Problem conclusion

  • The problem is fixed by an additional logic check that
    effectively removes the incorrect assumption that if the queue
    manager is not a full repository for the cluster, then it must
    be a partial repository. Removing this assumption informs the
    queue manager that it is possible that there should not be any
    subscriptions to validate.
