Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of strmqbrk
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    The WebSphere MQ code running in strmqbrk was making an
    incorrect decision to open a queue. The error path did not
    ensure the queue was closed.
    
    A later function in the code was trying to open that queue,
    but it was already open because of the earlier error.
    

Problem conclusion

  • The WebSphere MQ code has been fixed to ensure the queue is
    not opened, because it did not need to be opened.
