If Qmgr-A on Machine A and Qmgr-B Machine B are in the same cluster. And each Queue Manager has their own clustered local queue, can my WMQ Client program running on Machine C do a "get" from either of these clustered local queues?

Is there a setting to be able to do this with WMQ v6 ?

Or do I have to code the logic in my WMQ Client app to connect to each of these queues?

What's the best-practice in dealing with this scenario?


thanks

robsdman,

you have to code the logic in your WMQ Client app. Your app has to connect to one QMgr and then is able to read from
local queues. To read the same queue on another QMgr, the app has to connect to the other QMgr.

Or use the JMS Engine from WAS 6.0.
As the persistency store is a DB you might be able to do that in WAS.

The basic answer, as already explained, is "No".

An MQ app can only GET from qlocals on the qmgr it is connected to. One of the main points of MQ is that apps do not have to know where the queue they are putting to is.

Most people would put QMgr A on the samee machine as an instance of your Client App (and then use server bindings), and Qmgr B on the same machine as another instance of your client app (and use server bindings). And then have other applications connect to Qmgr C and PUT messages there.
