We have an AS/400 system, from where messages are being placed by an application into “Queue1”, local Queue on the production box.
We would like to duplicate (copy/mirror) messages put onto “Queue1” on the production box to a local queue “LocalQ1” on another Testing Server(Testing box).
Is it possible to duplicate/copy/mirror the messages from “Queue1” on the production box to a local queue “LocalQ1” on the Testing box? If so, how to get this done?
How to configure MQ series in such a way that when the AS/400 program puts a message on “Queue1” on the production box so that a copy of the message is put on “LocalQ1” on the Testing box.
Thank you |

Is there any reason why the application can't send two messages. One to the Production MQManager and one to the Test MQManager?
I was trying to think of a way to take advantage of TRIGGERING on the Production local queue. You could maybe write some code that would TRIGGER a PROCESS to copy the message then PUT it to a QRemote that would send the message to the Test MQManager. But if there is an application that has an open GET against the Prod QLocal I am not sure if the PROCESS you define would have time to get a copy of the message before the application pulls if off the Queue.

There was a similar question yesterday.... maybe Joan works with you??
Take a look at it anyway.
http://www.mqseries.net/phpBB2/viewtopic.php?t=17940.
Using triggering as csmith suggested is viable as well. I prefer the api exit implementation now that it is available. But if you want to try with triggering, click on the repository link above and select c programs. There is an early implementation of mirrorq that uses triggering. You will have to compile the source file for AS/400. If you don't have a c compiler, you could rewrite this portion in another language. It is very trivial. Also, there is one other change you need to make. I testing this using trigger every and didn't change the final copy. You should change the mqsc definition to use trigger first.

Hi,
You have 4 options:
- Install mirrorq SupportPac, make connections between the queue mangers and define a remote queue on prod to the dev queue.
http://www.developer.ibm.com/tech/sampmq.html
- Install MMX, Message Multiplexer (FREE C source code from Capitalware), make connections between the queue mangers and define a remote queue on prod to the dev queue.
http://www.capitalware.biz/sample_mqseries.html#ccode
- Purchase MQ Visual Edit (GUI program) and install it on DEV (or your workstation). Then have the user select a 'Backup' (in the GUI) of the PROD queue selecting all messages and write it to a file (includes MQMD and data). Then have MQBT 'Restore' the messages to the DEV queue.
For more info or to download a 30-day trial, go to:
http://www.capitalware.biz/mqbt_overview.html
- Purchase MQ Batch Tool and install it on DEV as a scheduled task (crontab entry). From DEV, have MQBT do a 'Backup' of the PROD queue (all messages) and write it to a file (includes MQMD and data). Then have MQBT 'Restore' the messages to the DEV queue.

Thank you all for the suggestions.
I will try if we can ask OTHER team members if they can modify the AS400 module that puts messages. but I am not sure if I get a +ve reply.
Roger.
Let me clarify if I understand it correctly.
The message are put on AS/400. The queue is a remote queue pointing to a local queue "LocalQ1" on a WIndows2000 server. Now I need to install the mirrorq support pack on Windows 2000 box. right?
Once installed, I will have to define a remote queue say "RQ2". Make it point to local queue "LocalQ2" on my testbox (which is another windows2000box.)
Please confirm if this is correct |
