Problem summary

  • ****************************************************************
    * USERS AFFECTED: All OMEGAMON XE for IMS on z/OS v4.2.0.      *
    ****************************************************************
    * PROBLEM DESCRIPTION: MRG099: Message Merge Task Terminating  *
    *                      Due To Error.                           *
    ****************************************************************
    * RECOMMENDATION: Apply this PTF.                              *
    ****************************************************************
    When the message merge program is restarting, it fails to
    correctly set its pointer to the Local WTO Hook Area "LWHA".
    Thus, it uses the LWHA address from the previous instance of
    of the message merge task. If the storage at this address
    is not accessible, then the results is a S0C4 Abend and
    message MRG099.
    

Problem conclusion

  • The message merge module has been changed to correctly set
    the LWHA pointer.
