Hello guys, I have a problem with registering topics in fact I have a problem with SYSTEM.BROKER.CONTROL.QUEUE, messages are just piling up on the queue.
I did a couple of things to trouble shoot, like checking if the "Get Messages" is allowed yes it is, then i checked the PSMODE yes its enabled.
since the messages are sitting there there should be something wrong with the PUBSUB DEMON, how to debug this issue??? there is nothing present is MQ error logs either.
Version: 7.0.1.3 please help. |

That's because that's not the queue you publish messages to! That's the queue you use to register your subscription.
Look up the manual and publish to the right queue!

Clear the queue, bounce the qmgr.
Specify a reply to queue. Send the message as request reply.
Use RFHUtil to read the message on the reply queue.
Check one of the tab. It will have the return code from the subscription registration.

Thanks a lot for the suggestion it worked I was not specifying message type
| Code: |
| SET OutputRoot.MQMD.MsgType = MQMT_REQUEST; |
so the reply never came to the replytoQ, this helped me debug the issue...
I have one more doubt when we put a message onto the SYSTEM.BROKER.CONTROL.QUEUE it replies with a message Id and CorelId (Collected from Output terminal of MQ Output node)
and the reply sent by the queuemanager to the queue name specified in
| Code: |
| SET OutputRoot.MQMD.ReplyToQ = 'REG_REPLY'; |
the message ID and corel Id dont match. is there any possible way to corelate a subscription request message to its corresponding response? |

What do you mean they don't match? Did you check the flags for correlID = msgID in the request message? (RFHUtil ?)
In any case the (successful) reply message should have the subscription topic and subscription destination in it. Look for it at the bottom window of the PSRC tab.
