Stopping a queue manager manually on UNIX and Linux

If we are unable to stop a queue manager on UNIX and Linux by using the endmqm command, we can try to stop the queue manager manually by ending any processes that are running and stopping the IBM MQ service.

About this task

To stop a queue manager on UNIX and Linux, complete the following steps.

If you stop the queue manager manually, FFST might be taken, and FDC files placed in /var/mqm/errors. This should not be regarded as a defect in the queue manager.

The queue manager will restart normally, even after you have stopped it using this method of stopping it manually.

Procedure

1. Find the process IDs of the queue manager programs that are still running by using the ps command. For example, if the queue manager is called QMNAME, use the following command:

   ps -ef | grep QMNAME
   

2. End any queue manager processes that are still running. Use the kill command, specifying the process IDs discovered by using the ps command.

   End the processes in the following order:

   Process name	Description
   amqzmuc0	Critical process manager
   amqzxma0	Execution controller
   amqzfuma	OAM process
   amqzlaa0	LQM agents
   amqzlsa0	LQM agents
   amqzmuf0	Utility Manager
   amqzmur0	Restartable process manager
   amqzmgr0	Process controller
   amqfqpub	Publish Subscribe process
   amqfcxba	Broker worker process
   amqrmppa	Process pooling process
   amqcrsta	Non-threaded responder job process
   amqcrs6b	LU62 receiver channel and client connection
   amqrrmfa	The repository process (for clusters)
   amqpcsea	The command server
   runmqtrm	Invoke a trigger monitor for a server
   runmqdlq	Invoke dead-letter queue handler
   runmqchi	The channel initiator process
   runmqlsr	The channel listener process

   Note: We can use the kill -9 command to end processes that fail to stop.
