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.
