We have a "leaky" application that needs to be restarted 1-2 times a week. It is deployed to a 2 node cluster. How can you stop one node/JVM without ending the sessions? The new sessions will go to the other cluster member and once all sessions have ended on the stopping JVM will the JVM actually stop.
The infrastrucure is setup like this: F5 Big-ip -> (2) IBM HTTP servers -> (2) Websphere 6.1
