Hi,

If i want to configure single MQM to support different testing environments like below, instead of setting up multiple MQM, what do you think?

ENV1 sender --> MQM.Queue.ENV1 --> ENV1 consumer
ENV2 sender --> MQM.Queue.ENV2 --> ENV2 consumer
ENV3 sender --> MQM.Queue.ENV3 --> ENV3 consumer

setting up a new MQ with environment as suffix is easier for me to setup new server, install new IBM MQ and create new MQ manager

Sorry for my poor searching skill. Haven't found any discussion about this idea on the web, can only find topics about mutli-instance or clustering.

thanks.

The number of queue managers on a single node is governed by the resources available on that node - you can have as many as capacity will allow.

If you are asking whether you can have one queue manager, which hosts queues for different environments then the answer is yes - a single queue manager can host those environments, but it's up to you to ensure the applications in one 'environment' do not interfere with messages from another.

It is a valid technique to use queue name suffixes to indicate the environment. A down side is that each app environment needs to be separately configured to use different queue names.

A common simplification is to use the same queue names across all environments, but use different queue manager names. This makes app deployment through the environment stages a bit easier.

This also insulates the test environments from each other. ie. A qmgr for one environment can be restarted, reconfigured etc. without affecting the other environments' qmgrs.

It is not a big deal to run multiple qmgrs on one server. I have seen up to 10 running on a moderately resourced server. YMMV.

thanks exerk and gbaddeley's reply. Actually i also like gbaddeley's idea to create multiple MQM. it save the effort of creating new VM but can separate messages.

By "MQM" do you mean Qmgrs (aka Queue Managers)?

I would prefix queue names with the environment rather than use suffixes. Then you can apply security to those queues more generically. But that is just me.
