Error description

  • The customer received an 0C4-00000004 abend:
    |ABN=0C4-00000004,M=CSQXDISP,LOC=CSQXADPM.|
    | ????????                                |
    .
    Cluster-sender was going into retry processing and
    rriWriteChannelCompMsg has invoked rriCommit to
    issue a commit.
    CSQXADPM has been invoked for the commit, and has
    detected that there is no cciConv for the channel,
    so fHaveConv has not been set.
    However, subsequent processing in CSQXADPM doesn't
    take notice of the fact that fHaveConv is not set
    in the case where commit process returns MQRC_BACKED_OUT,
    resulting in the 0C4.
    .
    For troubleshooting you need a MSTR and CHIN trace from
    the queue-manager to see why the commit has failed with
    MQRC_BACKED_OUT.
    However, it should not be causing the 0C4 in CSQXADPM.

    * PROBLEM DESCRIPTION: Abend S0C4 may occur in CSQXADPM if a   *
    *                      channel failure causes a unit of work   *
    *                      to be backed out.                       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If an internal or channel failure causes commit processing to
    fail and MQRC_BACKED_OUT is returned for the commit operation,
    an S0C4 abend may occur in module CSQXADPM.
    

Problem conclusion

  • Processing has been amended to ensure that an internal reason
    code of MQRC_BACKED_OUT cannot cause an abend to occur when
    processing a commit operation.
