I know that WebLogic Cluster will automatically create a session replica to a secondary server when user does something in his session, like calling session.setAttribute(key, obj).
However, suppose there are two managed servers in a cluster, a primary session and a session replica are on server1 and server2 respectively. Then server2 is shutdown and restart, I observe that the session replica is lost. (The user keeps idle and the session timeout is set very long, e.g. 1 hour)
What if server1 is shutdown in this moment? The primary session is also lost (while the session is not timeout).
So, I want to ask, is there any point in the operations I can tell WebLogic Cluster to replicate session to an available server without end user's interaction? Thanks for any suggestion.
