JDBC Connection Pools
A JDBC connection pool contains a group of JDBC connections that are created when the connection pool is registered, usually when starting up WebLogic Server. Your application borrows a connection from the connection pool, uses it, then returns it to the connection pool by closing it.
After creating a JDBC connection pool, you can create a data source that applications can use to access the JDBC connection pool.
The main JDBC Connection Pools page contains two tabs:
- Configuration - Which provides a link for creating a connection pool and lists currently configured connection pools.
- Monitoring - Which displays information about the state of each deployed instance of all connection pools. By default, the table includes the following columns. You can click Customize this view to display additional columns.
Server - The server on which the connection pool is deployed.
State - The current state of the connection pool: RUNNING or SUSPENDED.
Connections - The current number of physical database connections in the connection pool.
Waiters - The current number of applications waiting for a connection.
Num Unavailable - The current number of connections that are currently unavailable to applications because the connection is being tested or refreshed.
To create a JDBC connection pool, click the Configure a new JDBC Connection Pool link on the Configuration tab.
