This feature enables persistence of HTTP sessions to a datasource using JDBC. Persisting HTTP session data to a database allows recovery of the data after a server restart or unexpected server failure. Failover of HTTP sessions can be achieved by configuring multiple servers to persist data to the same location
To enable the Database Session Persistence feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>sessionDatabase-1.0</feature>
If you are developing a feature that depends on the Database Session Persistence feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
