Configuring Database Sessions (ELUG)
For the latest EclipseLink documentation, please see http://www.eclipse.org/eclipselink/documentation/
This table lists the configurable options for database sessions.
Configuring External Connection Pools
Unlike a server session, a database session does not provide internal connection pools. A database session only has a single database connection that it uses for its life cycle.
We recommend that you use a server and client session in a three-tier environment. Alternatively, you can use a database session with an external connection pool (see Configuring External Connection Pooling): in this case, you should allocate a new database session per user/thread or request.
WARNING: Do not allow the concurrent use of a database session by multiple users/threads.
The usage of an external connection pool reduces the number of the database session login and logout attempts to acquire the database connection.
