Hi , I have a requirement to deploy message flow across broker . Since when i deploy message flow in two broker then by default two instance will be created which is listening to the same queue.
I want to create this message flow single threaded across the multi instance cluster environment.

Have you thought doing an open with option exclusive of the queue?
Mind you this has a lot of other implications: like what to do when the process holding the queue open fails...

I'm confused entirely.

How does a multi-instance queue manager have two copies of a queue?

Why would a non-multi-instance broker be tied to a multi-instance queue manager?

Also, this is not in the right forum...

Okay, reading it again.

You are asking "How do I create a multi-instance broker instead of two single instance brokers?".

It's a good thing that there are step-by-step instructions in the knowledge center, otherwise I wouldn't know the answer to this.

Let the OP confirm following:

He has a farm of multiple consumers (hi availability of consumers) all listening the same queue of a multi-instance qmgr (hi availability).

He has a requirement that involves message affinity and can only have one consumer consume at a time.

Hence my comment for open exclusive...
