How to configure local queue to consume messages from multiple client applications? I have a queue manager A with a defined server connection channel B and a local queue C. Three batch applications will interact with this local queue through server connection channel B and consume messages the same messages and process the data differently. After all the client applications has consumed messages, the messages in the queue must go away.

Please let me know.

Thanks, Prakash

Queues don't consume messages.

Applications consume messages.

Applications shouldn't share queues.

Thanks Jeff for quick reply. What's the best way so that my 3 applications will consume all messages from this local queue. Also, these three batch applications will interact with the queue in different times.

Thanks for your help.

You should have different queues for each application.

but it sounds like the same message needs to goto 3 different applications for different processing...

if that's the case I'd suggest a couple options

- pub/sub (if you can change the code on the producing and consuming apps)
- distribution lists - if you can change the code of producing apps
- mirrorq (or something similar) to copy the input message into 3 seperate queues for the consuming apps.

It's very difficult to have 3 different applications read the same message.
