Error description

  • If ending the queue manager with the option "-i" when the
    channel is running, the channel status is "STOPPED" after
    restarting the queue manager. WebSphere MQ
    fails to save the channel status.
    From the trace, the function rriSaveChannelStatus fails.

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users running on MQ 7.0, MQ 7.1 and MQ 7.5 using
    channels may face this issue.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    On a channel if we issue start channel after stop channel before
    the stop channel thread has completed its processing, the
    start channel status will not be saved. Hence when the queue
    manager is restarted the channel moves into STOPPED state rather
    than INACTIVE state as the channel status
    was saved during start channel.
    

Problem conclusion

  • The code changes made will call the save channel status function
    to make sure that the start channel status has been saved when
    the start channel command is issued. This channel status will be
    remembered during the next restart of the queue manager.
