| What are you using for a broker? Are you sure that the messages are intended for this particular subscriber? Are you using durable or non-durable subscribers? When you say that get processed some time later, does this mean your program ends and restarts? |

| I'm guessing that your downloaded broker is SupportPac MA0C? How do you start it? Durable subscribers mean that the subscriber program can end, come back later, and get all of the subscriptions that were published while it was away. Non-durable subscribers only get the subscriptions while they are running. |

| you are right its mq support pac MAOC. The broker starts automatically when the system starts, i don't know whether my it is durable or nondurable. Is there any trace i can do on Mq to see if its not giving messages to the application???? |

is that receiving application is a custom built or a vendor application?
looks like durable or non-durable is a swtich you use while calling the application. You might want to search for "durable subscribers" on search area of this website to see how you can set that switch or the documentation of that supportpac. |

You could certainly turn on tracing and see what it shows. However, the trace files makes calls to various internal functions and deciphering them may not be an easy thing for you to do. Usually if it comes to taking a trace, you need to call IBM support.
As far as durable or non-durable, I was only interested if you were seeing messages on your queue because you had orphaned durable subscribers (ie, you didn't deregister them). I don't know that this is actually the source of your problem.
There were several fixes in some of the earlier CSDs that were related to messages not being received. I don't know of any that are post CSD7. Are you using any kind of selector to get your messages? |

| You use the strmqtrc command to turn on trace. It will create a bunch of *.trc files in your wmq\errors subdirectory. Details are in the Systems Administration manual. |
