Error description

  • The following 0c4-4 abend occurs at the time of CHINIT shut
    down:
    DUMP TITLE=CSQ2,ABN= 0C4-00000004,C=MQ900.911.CHIN,M=CSQXJST
    ,LOC=CSQXJST .CSQXJST +0469A
    .
    Additional Keywords:
    ABEND0C4 ABENDS0C4 S0C4 S00C4
    

Local fix

  • Configuring the queue manager's EXITTCB parameter in CSQ6SYSP to
    be a non-zero value should prevent the abend from occurring.

    * PROBLEM DESCRIPTION: ABEND 0C4-4 in CSQXJST at shutdown when *
    *                      EXITTCB=0.                              *
    ****************************************************************
    ABEND0C4 in CSQXJST during shutdown when EXITTCB=0 is specified
    on the CSQ6SYSP macro in CSQ4ZPRM. The failure occurs when
    testing whether the cluster workload exit monitor task CSQXRFEA
    should be re-attached after failing earlier because no server
    tasks were specified on the EXITTCB parameter.
    The lack of any server tasks to process cluster workload exit
    requests is reported during startup with message CSQV452I
    'Cluster workload exits not available'.
    
    Additional keywords: CSQX_ABEND_CLWX_NO_SVR_TASKS
    

Problem conclusion

  • Module CSQXJST has been updated so that it will not attempt to
    re-attach CSQXRFEA if it previously failed because no server
    tasks were available.
