Error description

  • If an uncaught exception causes a flow to be rolled back to a
    GroupComplete node and the "catch" terminal of the node is not
    wired then the group message that caused the failure is
    discarded. The next group that is processed by the node is then
    sent to the "failure" terminal rather than the appropriate
    terminal for that group.
    
    The correct behavior is that the failed group is discarded and
    a message is written to the syslog. Future groups processed by
    the node should be unaffected by this failure.
    

Local fix

  • Apply APAR IT27206 and wire the catch terminal
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of the Group nodes in IBM App Connect Enterprise v11
    and IBM Integration Bus v10.	
    
    
    Platforms affected:
    AIX, Linux on x86-64 platform, z/OS, Windows on x86-64 platform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    If an uncaught exception reaches the GroupComplete node, and the
    catch terminal is not wired, then the node will mark the group
    as failed and discard the group. If another group is received by
    the discarding thread within 5 seconds of the original group
    being discarded then this second group message is incorrectly
    routed to the "failure" terminal.
    

Problem conclusion

Temporary fix
