Hi All,
I am facing a scenario where the consumer is not able to see the message on the queue, while he is waiting to get the message with Correaltion Id and MQ Wait. But after the wait time expires the message is visible on the queue instantly.
The GMO Option of the get client are GMO_WAIT, GMO_CONVERT, ACCEPTTRUNCATED. The consumer is a mainframe application and the queue manager is also hosted on MainFrames.
The put application is DataPower. If the consumer had set a wait of 20sec the message arrives 21st second.
I represent the put side of the application and dont face any issues when i test it myself, request you to kindly provide any info that can help in resolvin the issue.
Thanks,
Ajay. |

And just when do you commit that message? z/OS systems are implicitly transactional in nature so I suggest you have the receiving end check the queue's UNCOM return during the 20 second lag time.
And what's the poll for? You'll get both if it's a message uncommitted before the wait time expiry...

| I believe DataPower commits the transaction as soon as the message is placed on the queue, i can check that. Whats with the UNCOM is this the uncommitted messages count on the queue? |

Please do - I'm no DataPower expert.

Correct.

What is the backout count of the message at this point?

There is no way, no how, that the wait time of a consumer determines when the message initially arrives on the queue coming from another application, DataPower in this case.

Explain exactly what you mean the message is not visible? Is visible? What tool or program are you using?
2033 means no (matching) message available. How have you defined and used the Correlid?

Typical request response problem. Your request program is not committing the request until the time out. At which time the response comes under a second wait time...
You cannot get a response to a request until the request is committed.
Have fun

| Thank you for your help, to add to that i was able to see that whenever the consumer/get application is not polling on the queue for messages the message does arrive within the wait time. Its only when the consumer is polling on the queue that the message arrives after the wait time expires. |

First make sure your units of work are set correctly. Post back once you have verified this.

What consumer on what queue, please be specific.
The mainframe app on the input request queue?
Or your DataPower app on the reply queue?
