All Implemented Interfaces:

java.util.EventListener, Lifecycle, Manager, java.beans.PropertyChangeListener, java.lang.Runnable

public final class PersistentManager

extends PersistentManagerBase

Implementation of the Manager interface that makes use of a Store to swap active Sessions to disk. It can be configured to achieve several different goals:

Persist sessions across restarts of the Container

Fault tolerance, keep sessions backed up on disk to allow recovery in the event of unplanned restarts.

Limit the number of active sessions kept in memory by swapping less active sessions out to disk.
