    * PROBLEM DESCRIPTION: In ME to ME communication for publish   *
    *                      subscribe messaging the health of       *
    *                      environment is difficult to             *
    *                      predict and requires too much tracing.  *

    * RECOMMENDATION:                                              *
    ****************************************************************
    In Messaging Engine to Messaging Engine communication for
    publish subscribe messaging the health of environment is a
    little difficult to determine and requires too much tracing to
    be enabled to draw conclusions. SIBProcessor=all needed to
    be enabled on all servers and it was having a huge impact on
    performance.
    

Problem conclusion

  • With this APAR we have enhanced tracing to capture the summary
    of communication and print out vital information with minimal
    overhead.
    
    This new tracing can be enabled with SIBGDHealth=all trace
    string.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.39 , 8.0.0.11 and 8.5.5.6 .  Please refer to
