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.
Oracle recommends 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.
