Publisher is an app that has multiple instances. One instance connects to QM1 and another connects to QM2.
The subscribers will be connected to QM3.
The MQ Pub Sub Broker only runs on QM3.
There are regular SNDR / RCVR channels between QM1 / QM2 and QM3, and there are multiple hops between QM1 / QM2 and QM3.
Is there anyway to make this work? Can the multiple instances of publishers remotely register with QM3? And then send publications into remote queues on QM1 / QM2 that aim at the stream queue on QM3?
Or do we have to build a little publisher app connected to QM3 that listens for plain MQ messages from QM1/QM2 and then publishes them directly to QM3?

v7 distributed pubsub should allow this to work with minimal setup. If I understand it correctly, that is.
Since you mention SDR/RCVR I guess you've ruled out a cluster.. in that case I think you can still do distributed pubsub but you would have to have a child/parent hierarchy.
I think you'd need CHILD/PARENT settings on the qmgr. |

Forgot to mention all QMs involved are MQ 6 and we need to make it work with MQ 6.
MQ 7 will not happen prior to the project going live.

I'm not familiar with that QM setting.

I'm looking for a solution that does not involve enabling Brokers all over the place.

When creating your TCF you need to specify the BROKER qmgr and it may be a different qmgr from the one you're attaching to.
Check TCF definition. This implies that you have a default path between attached qmgr and broker qmgr, and vice versa.
If you want a distributed type of publish you will need a cluster and a collective. We set up a system with no single point of failure, including for pub/sub (get my professional email from Jeff and ping me if you need more details, I see PMs have been disabled...)
