Connection Pools
A JDBC connection pool contains a group of JDBC connections that are created
when the connection pool is registered. Connection pools use a JDBC driver to
create physical database connections. Your application borrows a connection from the pool, uses
it, then returns it to the pool by closing it. To create a
JDBC resource, specify the associated connection pool. Multiple JDBC resources can specify a
single connection pool.

A JDBC connection pool is a group of reusable connections for a
particular database. Because creating each new physical connection is time-consuming, the server maintains a
pool of available connections to increase performance. When an application requests a connection,
it obtains one from the pool. When an application closes a connection, the
connection is returned to the pool.

When creating a connection pool with the Administration Console, you are defining the
aspects of a connection to a specific database.

Use the JDBC Connection Pools page to configure JDBC connection pools.

For each connection pool, the following information is provided.

Pool Name
The name of the connection pool.


Resource Type
The resource type of the connection pool.


Classname
The name of the vendor-specific class that implements the javax.sql.XADataSource, java.sql.ConnectionPoolDataSource, javax.sql.DataSource, or java.sql.Driver API.


Description
A short description of the connection pool.



The Pools table also contains the following options.

New
Button to create a new connection pool.


Delete
Button to delete one or more selected connection pools.
