Configuring Internal Connection Pools

An internal connection pool is a collection of reusable connections to a single data source provided by any session that persists to a data source. By default, such a session provides both an internal read and write connection pool.

In this case, you can do the following:

• Configure read and write connection pool options such as minimum and maximum number of connections, alternate connection configuration, and properties (arbitrary, application-specific named values).

• Create named connection pools for whatever application-specific purpose you choose.

• Create sequence connection pools that TopLink uses exclusively for obtaining object identifiers.

For more information about creating and configuring internal connection pools, see the following:

• "Creating an Internal Connection Pool"

• "Configuring an Internal Connection Pool"

For more information about configuring the type of connection pool your session uses, see "Configuring External Connection Pooling".

Configuring External Connection Pools

An external connection pool is a collection of reusable connections to a single data source provided by a JDBC driver or J2EE container.

By default, a session uses internal connection pools (see "Configuring Internal Connection Pools"). For more information about configuring a session to use an external connection pool, see "Configuring External Connection Pooling".
