I have a question, whether we can use Comma Separated 2 different IPs (belonging to 2 different servers and with the same name queue managers) in CHLTABL file?
and how it will behave, so the connections would be tried in the order of IP's addresses listed until a connection is successfully established?
Regards,

That's the way it's supposed to work. I would however go one further and always specify the port as well. Expecting it to work with the default port is not a given. Works until somebody changes the default port for the qmgr...

We should just say that the only time you should have the same Queue Manager name existing at two different IP addresses is when you are using multi-instance. It is NEVER a good idea to have two completely different Queue Managers with the same name. For example, normal sender/receiver channels will not cope with this very well.
Cheers,
Paul.

And Lord help you if you try and cluster two queue managers of the same name...

You provide IP addresses OR host names, not both.
Why do you have two queue managers with the same name on 2 different servers?

And if you do, can you verify if those are multi-instance queue managers?

I mean, we would be providing both HostName and port number, sorry earlier was typo.
We don't have multi-instance queue manager.

Please explain why you have 2 servers with the same queue manager name.
Both servers on the same network?
Both servers up at the same time?
