Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All Users of IBM integration Bus V9.0 and V10.0 using Resequence
    node.
    
    
    Platforms affected:
    z/OS, MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    Exceptions which trigger the Resequence node to restore its
    previous state, can cause further messages of same group stuck
    in its internal queues.
    
    For example, a BIP2136E error when serializing an incoming
    message tree can cause the Resequence node to restore to its
    previous state, thus losing track of the state of group.
    
    A usertrace or service trace will show BIP2112E error, shown
    below, when such problem occurs:
    
    BIP2112E: Message broker internal error: diagnostic information
    ''failed to get message for event''
    

Problem conclusion

  • The Resequence node no longer fails to restore its previous
    state when an internal exception occurs.
