You kill it with fire.

Then you delete it.

Then you remove the installation directories for the broker and MQ.

Then you delete the root of the file system on which they're - were - running.

Then you unplug the machine.

Ehr... FYI: ONLY try this at home. Otherwise people may become a bit cross with you.

It normally means you have a message flow that is badly written and has gone into a wait state (probably for an external resource). Or the flow has called some Java code that does its own thing.

You can force it to stop with mqsistop -i <brokername>

That will stop the entire broker. Look at the flows and correct them, make sure all external calls have a timeout specified (NB this includes data sources in ODBC).

@zpat

Of course my response was based on the assumption that @upender was posting a bunch of exam or practice questions. But you already guessed that.

No, do this at work. Do the industry a favor.

@Vitor, your autocorrect is stuck in the *wrong* language again.
