Hi guys.
I have a question about horizontal scaling. My broker has version 8.0.0.4.
I already have 2 FR MQ (Active-Active) with 2 intances of Broker (multi-instance broker).
Will I need to create a PR MQ + Broker, if I add another MQ + Broker (Acticve)?

I will infer from what you say that the two FR Qmgrs are also your two Broker Qmgrs and these resources are configured as MI.
If this is the case, then yes your next Qmgr/Broker will be a PR.
How are you load balancing your MQ traffic into the broker Qmgrs?
Just because you load balanced your MQ traffic between these Qmgrs, doesn't mean the broker work load is balanced by capability. In deed, two of three of these Qmgrs is also MQ FR processing which may affect the broker work load capacity.
I would not use an application Qmgr as an FR. I would instead, create another Qmgr (even if it has to be on the same hardware) to be an isolated FR. This will eliminate the temptation to suspend an FR from the cluster or do odd things. |

And let's pretend that all your incoming to the broker traffic is WebService based, over HTTP.
All that MQ clustering does nothing. |

Thank you for your advise.

So, if I have 2 FR MQ and 2 PR MQ (which is used by Broker instances), Will broker work load be balanced?

Only if you've configured it so. Just having queue managers in a cluster doesn't load balance anything. Consider what would happen if you had a flow with an MQInput node in each broker, with the same local queue in the matching queue manager. There would be no load balancing unless you deliberately set the cluster attributes on the queues, only on these queues, and according to those cluster attributes you set.

What my most worthy associate is getting at is that any traffic which doesn't flow over WMQ (i.e. web services over TCP/IP) will ignore any WMQ configuration and not be load balanced by anything you've described here.
