Missing Messages..
Any thoughts would be appreciated. We have a situation where MQ/ESA V1.2 on system BSYS is communicating with MQ for z/OS V5.3 on ESYS. A program was run to get about 1000 messages from BSYS and send them to a shared queue on ESYS. After the program ran, there were 994 records in the ESYS queue, and 6 messages in the BSYS queue. But when we run a program to get those records on BSYS, it indicates that there are no records in the queue on BSYS. I don't have the MQRC yet. But I wonder if there could be a unit of work problem (or other problems) because we are running such an old version of MQ on BSYS and we are using shared queues on ESYS. If so, are there any compatibility APARs that could fix this?

Updated , disregard previous question due to incorrect information Any thoughts would be appreciated. We have a situation where WSMQ 5.3 on system BSYS is communicating with WSMQ 5.3 on ESYS. A program was run to get about 1000 messages from BSYS and send them to a shared queue on ESYS. After the program ran, there were 994 records in the ESYS queue, and 6 messages in the BSYS queue. But when we run a program to get those records on BSYS, it indicates that there are no records in the queue on BSYS. I don't have the MQRC yet. Details to bear in mind; 1. Message flow between BSYS and ESYS does not use WebsphereMQ channels to transfer messages. 2. All messages were put with Expiry Time = Unlimited 3. WSMQ on BSYS and ESYS are at the same level of 5.3 4. After the test, inquiry of the status of the source and destination queues showed no uncommitted unit of work Stewart Stewart Herd Senior Software Engineer Systems Engineering Services ACS NSC Campus Loughmahon Technology Park Cork Ireland
Re: Missing Messages
Sounds Like you still have an active resource connected to that queue. I have seen this in the windows world but not on the 390 world. Worth a shot though.

Application using BROWSE missing messages
hi all... I am looking for some help to solve a particular problem that we are facing here. The problem is explained below. We have a MQ based application written in C++ running in CICS and reading messages from MQ. The overall functioning logic of the application is as explained below. ||--( 1 ) Input queue opened for Browse with options and read in a LOOP till messages are over. ||MQGMO_WAIT + MQGMO_FAIL_IF_QUIESCING + MQGMO_BROWSE_NEXT+MQOO_INPUT_SHARED | |and wait interval as 0. | | | |( 2 ) Use message (May have syncpoint calls in this process) | | | |( 3 ) IF DB deadlock of -911 THEN | |is got then ROLLBACK everything uncommitted, and repeat step 1 onwards with | |the following options MQGMO_WAIT+MQGMO_FAIL_IF_QUIESCING+MQGMO_BROWSE_FIRST | |Change here is that the queue is again reopened fresh with a Browse_First option as shown above. | |ELSE | |Remove the message under syncpoint control with a destructive Get with the | |following options, MQGMO_WAIT + MQGMO_FAIL_IF_QUIESCING + MQGMO_MSG_UNDER_CURSOR | |+ MQGMO_SYNCPOINT | | ENDIF | | | |--- ( 4 ) Perform a SYNCPOINT in CICS | | ( 5 ) Out of above loop when no more entries left in queue on error code 2033 | |( 6 ) Infinite wait on MQ Read by using the below options , |MQGMO_WAIT + MQGMO_FAIL_IF_QUIESCING + MQGMO_BROWSE_NEXT and MQWI_UNLIMITED |Transaction is waiting on MQ to alert and wake this guy up when a message arrives. | |--- ( 7 ) Message arrives in queue and from this point step 1 onwards is repeated PROBLEM In the above logic that we are using we are using we have noticed that some-times a queue has 1 or 2 messages and the transaction in CICS is in GETWAIT waiting for messages to arrive. The 2 messages which get left out are never picked up where as further messages which arrive in that input queue are picked and processed. Anybody facing a problem like this or know of something in this regard. Also i see a PTF at the IBM site closed recently with details as below APAR CLOSEDATEyy/mm/dd PTF(s) Fixing APARif PTF in error HIPER? Description/comments PQ61246 02/08/15 UQ68768 MQGET WITH WAIT ISN'T POSTED ALTHOUGH THE QUEUE HAS A MESSAGE. Any IDEA as to how to get the details for this.. or anybody out there who might have actually have raised this particular problem. Any help would be highly appreciated. Thanks and regards Sridhar R
Re: Application using BROWSE missing messages
Sridhar, why don't you just open an issue with IBM and ask for more detail? Or describe to them what you have and askif the apar you found fits.

Re: Application using BROWSE missing messages
hi ronald.. This is not the case as i have all my transactions fully committed and in their sleep states. I also verified the number of threads and processes holding this queue and did not find any except the one reading and waiting on this. Somehow these 1 or 2 messages stays in the queue.
