Stopping queue managers in WebSphere MQ for UNIX systems

 

To stop a queue manager running under WebSphere MQ for UNIX systems:

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

   ps -ef | grep QMNAME

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

   End the processes in the following order:

   amqzmuc0	Critical process manager
   amqzxma0	Execution controller
   amqzfuma	OAM process
   amqzlaa0	LQM agents
   amqzlsa0	LQM agents
   amqzmgr0	Process controller
   amqzmur0	Restartable process manager
   amqrmppa	Process pooling process
   amqrrmfa	The repository process (for clusters)
   amqzdmaa	Deferred message processor
   amqpcsea	The command server

Processes that fail to stop can be ended using kill -9.

If you stop the queue manager manually, FFSTs might be taken, and FDC files placed in /var/mqm/errors. Do not regard this as a defect in the queue manager.

The queue manager should restart normally, even after you have stopped it using this method.
