Error description

  • A customer may receive the following error messages during CICS
    shutdown PLT processing:
    .
    DFHAC2236 mm/dd/yyyy hh:mm:ss applid Transaction CKBR abend AMQH
    in program DFHMQBR0 term ????.  Updates to local recoverable
    resources will be backed out.
    .
    DFHMQ0102 E mm/dd/yyyy hh:mm:ss applid Cannot start the CICS
    transaction CKBR.  EIBFN=1008 EIBRESP=16 EIBRESP2=17
    .
    The second message simply means that CICS cannot start the CKBR
    transaction because CICS is in shutdown processing and CKBR is
    defined as shutdown=disabled in the CSD.
    The problem here is that a message has been received/processed
    by CKBR at the same time as the shutdown has been initiated,
    which results in the EXEC CICS START failing with RESP=16 and
    RESP2=17. It does look as though it is unnecessary for CKBR to
    issue an AMQH abend in this situation.

    During CICS shutdown CKBR attempts to START a transaction and
    because the transaction is defined to CICS as SHUTDOWN DISABLED
    the START fails, returning EIBRESP=16, EIBRESP2=17.
    CKBR does not handle this condition and abends AMQH.
    Keywords: MSGDFHAC2236 MSGDFHMQ0102 MSGDFHMQ0704
    

Problem conclusion

  • DFHMQBR0 is changed to handle the START failed condition and to
    output messages DFHMQ0704 E and DFHMQ0760 I which details the
    MsgId of the message that prompted the START command.
