Failing over a multi-instance integration node and queue manager

An active integration node instance fails over when its associated active multi-instance queue manager either terminates unexpectedly, or stops in a controlled manner. The action of stopping an active integration node instance on an active multi-instance queue manager does not by itself cause a standby integration node instance to become active.

• Controlled failover.
  • Switch over to a standby instance by stopping an active queue manager with the endmqm command:

    endmqm -s QueueManager

    where QueueManager is the name of the queue manager that you are stopping. As the active instance of the queue managers goes down, the standby instance starts.
• Immediate failover.
  • Stop an active queue manager process with the kill command on Linux® and UNIX, or end the process with the Windows task manager on Windows:

    kill -9 amqzxma0 ProcessID

    where ProcessID is the process ID of the amqzxma0 process that you need to kill. The standby instance of the queue manager becomes active.
• Shutting down the server.
  • Restart the server that the active instance of the queue manager is running on. The standby instance of the queue manager becomes active.
