IPPROCS or OPPROCS greater than 0 in a queue prevents normal termination of queue manager by "endmqm QmgrName" (Need to use: endmqm -i QmgrName)

Troubleshooting

Problem

You notice that when the IBM MQ queue attributes of IPPROCS or OPPROCS are greater than 0, and try to end the queue manager by issuing "endmqm QmgrName", then the queue manager goes into "quiescing" but it does not fully terminate. Is there a way to speed up the shutdown of the queue manager?

Resolving The Problem

The recommended way to end the queue manager and avoid a potential long quiescing state is to specify the flag -i (immediate):

- For Standalone queue managers,
endmqm -i QmgrName

- For Multi-Instance queue managers:
endmqm -is QmgrName
