Session recovery support

 

For session recovery support, WebSphere Application Server provides distributed session support in the form of database sessions and memory-to-memory replication. Use session recovery support under the following conditions:

1. When the user's session data must be maintained across a server restart
2. When the user's session data is too valuable to lose through an unexpected server failure

All the attributes set in a session must implement java.io.Serializable if the session requires external storage. In general, consider making all objects held by a session serialized, even if immediate plans do not call for session recovery support. If the Web site grows, and session recovery support becomes necessary, the transition occurs transparently to the application if the sessions only hold serialized objects. If not, a switch to session recovery support requires coding changes to make the session contents serialized.
