Error description

  • The MQ Bridge monitor transaction, CKBR, failed on an MQGET with
MQCC(00000002) MQRC(000007F2) which is
'MQRC_NO_MSG_UNDER_CURSOR'.
  It looks like there was 'no_msg_under_cursor' between the
'browse' and this 'get'.
Trace entries:
nnnn L800C AP A0B5 MQTRU *EXC* CSQCCCRC        00000002,000007F2
nnnn L800C AP A091 MQTRU EXIT  APPLICATION-REQUEST   MQGET
                                               00000002,000007F2
                                                               .
This shouldn't terminate the CICS-MQ bridge, but did in this
case, and the following message was received.
DFHMQ0713 I .. CKBR nnnnn CICS-MQ bridge terminated normally.
                                                               .

Problem summary

  • ****************************************************************
* USERS AFFECTED: All CICS/MQ users                            *
****************************************************************
* PROBLEM DESCRIPTION: The CICS/MQ bridge monitor transaction  *
*                      CKBR, fails on an MQGET with            *
*                      MQCC(00000002) MQRC(000007F2) which is  *
*                      'MQRC_NO_MSG_UNDER_CURSOR'. This leads  *
*                      to the CICS/MQ bridge terminating.      *
****************************************************************
The CICS/MQ bridge monitor transaction CKBR issues MQRC 07F2
then the CICS/MQ bridge terminates, which should not happen.
The MQRC condition arises because CKBR detected that a bridge
queue message it had previously browsed had not been processed
by the CICS/MQ bridge processor task CKBP. CKBR is therefore
trying to GET the message to place it on the DLQ but this fails,
probably because the message has been processed simultaneously
by another bridge task. This is a valid condition which is not
being handled correctly by the CKBR program logic.

Problem conclusion

  • UI64155 UI64156 UI64695 UI64693 UI64852
DFHMQBR0 has been changed to handle MQRC 07F2 as a normal
condition, and keep the CICS/MQ bridge running.
