| Can someone share a queue manager script that waits and kills processes in the correct order after a wait period. used to have one in the past and it is common enough figured i would ask here if someone can share if they have one they currently use. |

The endmqm command "kills" all the processes in the correct order.
If you mean that you want to signal application processes to shut down, then wait a period of time for them to do it, then shut down anyway, it's the endmqm command, followed by a sleep command, followed by an endmqm command with a -i parameter.
If you mean something else, then you need to explain it more.

Do you have a qmgr that doesn’t end normally - with endmqm?

| Am surprised you guys haven't come across this ... Many a times a endmqm -i runs for a long time...we end up killing mq processes in a specific order that is documented in infocenter. |

We've all come across this. How to stop a qmgr is a very basic MQ concept.
I'd guess that some application ignored your runmqm -c. Next time you plan to do an endmqm, display (with MQSC commands or MQExplorer or equivalent) active connections.
The -c switch (default) allows all connected apps to continue until MQDISConnect - but no new connections. The -i switch allows all current MQI calls to complete but no new MQI calls.
The -p switch ends the qmgr without waiting for either of the above. The qmgr ends normally with -c, -i, and -p.
All MQI calls should include _FAIL_IF_QUIESCING option so that the app will understand that the qmgr is being shut down while the app is running. An MQGET call with an infinite WAITINTERVAL will behave as you've observed.

If -i doesn't work, you can try -p.
The problem with scripting kill -9 is that the list of processes and the correct order is dependent on MQ version, possibly on fixpack level as well.
If you are regularly killing processes, you should raise a Service Request with IBM to understand why you need to do this. Its definitely abnormal. There may be some underlying OS or resource issue.

It's very seldom (in my personal experience) for a -i to run for a long time. Each instance I can remember I've traced to a contact admin who coded an MQGet with an unlimited wait and no fail if quiescing. Those you resolve with a -p and a good solid talk with the idiot responsible.
I've brought down a queue manager using kill -9 in the order specified I think half a dozen times in over 20 years, and in each instance there was a crisis at the server level.

If this happens so often you need to script for it, you have a serious problem.
