Changing the IP for the Queue Manager

To change the LifeKeeper protected IP associated with the WebSphere MQ queue manager, follow these steps:

1. Create a new LifeKeeper virtual IP in the LifeKeeper GUI.

2. Add the new virtual IP to the WebSphere MQ hierarchy.

3. Remove the old virtual IP from the WebSphere MQ hierarchy.

4. Delete the old virtual IP resource.

5. If needed, modify your listener object in runmqsc and restart the listener:

su – MQUSER
runmqsc QUEUE.MANAGER.NAME

alter LISTENER(SYSTEM.DEFAULT.LISTENER.TCP) TRPTYPE(TCP) PORT(1414) (IPADDR192.168.1.101)
stop LISTENER(SYSTEM.DEFAULT.LISTENER.TCP)
start LISTENER(SYSTEM.DEFAULT.LISTENER.TCP)

As an alternative, you can use the LifeKeeper lk_chg_value facility to change the IP. See the lk_chg_value(8) man page for details.
