Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Whilst stress testing our DPL bridge we were getting a number of
  error messages for transaction CKBR.
  These were a pair of messages:
  DFHMQ0760I and DFHMQ0762I and CICS Info Centre points you at a
  preceding message which should be  DFHMQ0710E.
  
  But basically in the dump I can see several
  
  AP A0B5 MQTRU *EXC* - CSQCCCRC - MQCC(00000002) MQRC(000007F1)
  
  Then I can see messages DFHMQ760I and DFHMQ0762I being issued .
  But I do not see DFHMQ0710E message with MQRC=2033.
  

Local fix

• NA
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Missing error message as a result of    *
  *                      setting ROUTEMEM=Y and the mark browse  *
  *                      interval expiring which results in the  *
  *                      following messages DFHMQ0760 and        *
  *                      DFHMQ0762 being issued.                 *
  ****************************************************************
  When running the CICS MQ Bridge with option ROUTEMEM=Y under
  load it can happen that a marked message interval will expire
  resulting in the message again becoming available to the CKBR
  transaction. In this case, because the message has already been,
   processed it is removed from the input MQ queue and the
  messages DFHMQ0760 and DFHMQ0762  are issued.
  The message text of the above messages refer to a previous
  message, but this was never issued.
  

Problem conclusion

• New message DFHMQ0795I has been created that describes this
  condition.
  
  The CICS Transaction Server Version 5 Release 4 and Version 5
  Release 5, CICS Messages manual will be updated as follows.
  In Chapter 2. DFHMQnnnn messages - a new
  message will be added immediately after the description of
  message DFHMQ0793I. This new message description will read as
  below.
  
  DFHMQ0795 E date time applid tranid trannum The CICS-MQ bridge
  has retrieved a message which has been previously marked and the
  mark browse interval has expired.
  
  Explanation: The CICS-MQ bridge is running with ROUTEMEM=Y and
  retrieved a message which has been previously marked and the
  mark browse interval has expired without the message having
  been processed. The transaction that should have processed the
  message could have been delayed for a period that exceeds the
  mark browse interval.
  
  System action: The message is removed from the bridge queue.
  
  User response: Check for associated messages to determine if the
  message was returned to the bridge queue or moved to another
  queue. Investigate potential transaction delays.
