Hello guys,
I'm very new at MQ, could some one help me with the following:
What is the best way to automatically transfer messages from one queue on an MQ Server to another queue on a different MQ server?
In other words, if Q1 receives a message on Server_1, I want it to be transfer to Q2 on Server_2. Once transfer the message on Q1 should be discarded (popped). While Q2 holds the message until some service pops it out of the queue.
Please keep in mind that I will be expecting about 500 transactions a second... So it needs to be the most efficient possible way.
Thanks in advance... And my apologies for the perhaps very simple question. |

| Use a remote q def on server 1. Have a read in the manuals for more info. |

Please clarify...do you mean, Q1 is a QLOCAL, and you want to take a message from it, send it to Q2, and when it is safely on Q2, the copy of the message on Q1 is then discarded?
If you don't mean the above, then WMBDEV1 has nailed it, if you do mean the above DON'T do it, you are heading for a whole world of hurt.
Again, please clarify exactly what it is you mean, and we can be of more help.

Even I take time off from this forum sometimes!
And clearly my apprentice was up earlier than me this morning.
(And no, not hung over before you ask!)

That's not a lot of transactions for a properly configured WMQ setup on decent hardware.

This is about as simple as questions get. What you're describing is the example setup shown in the Intercommunication manual. There's even a diagram to assist you.
The advice of my associate is exactly right, and you should follow it rather than the slightly convoluted method you originally posted. Much of what you seem to be trying to do (like not deleting the message from Sever1 until it's safely on Sever2) is handled automatically by the software. That's why your site has paid IBM quite a lot of money in license for it.
Which leads me to my point (yes, I did have one!). The advice of my associate is exactly right. It also assumes that you have properly configured WMQ communication between the 2 servers. This is also described in the Intercommunication manual (on the same diagram IIRC). As you described yourself as new, I felt I should underline this point.

If I make it clear more, the messages when you put on RDQ it goes basically through XMITQ to Remote LOCAL queue on REMOTE queue manager. And There is NO copy of the Message on the queue manager where you might have defined RQD.

A slightly simplistic view, ignoring the questions of syncpoint & channel batching, but yes.
