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:

• "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".
