4 Enabling State Session Persistence

ActiveCache can use Coherence*Web to provide HTTP session state persistence and management. Coherence*Web is a session management module that uses Coherence for storing and managing session data. Built on top of Oracle Coherence, Coherence*Web:

• brings Coherence data grid's data scalability, availability, reliability, and performance to in-memory session management and storage.

• allows session sharing and management across Web applications, domains, and heterogeneous application servers.

• allows storage of session data outside of the Java EE application server, freeing application server heap space and enabling server restarts without session data loss.

• supports multiple advanced session models (that is, Monolithic, Traditional, and Split Session) which define how the session state is serialized/deserialized in the cluster.

• supports fine-grained session and session attribute scoping by way of pluggable policies.

For information on using Coherence*Web with WebLogic Server applications, see the User's Guide for Oracle Coherence*Web.
