The driver implements a standard JDBC connection pool. Set UseConnectionPooling to enable the pool. The following sections show how to configure and use them.

Working with Pooled Connections

Just as you would interact with a non-pooled connection, you use standard JDBC objects to get and close connections. But, in this case, the Connection object retrieved is a handle for the physical connection owned by the connection pool. When the connection is closed, instead of the connection being destroyed, the handle is returned to the pool, where it is available for the next connection request.

You must explicitly close the connection for it to be returned to the pool.

Configuring the Connection Pool

In addition to UseConnectionPooling, set the following connection properties to control the connection pool:

• PoolMaxSize: Define the maximum number of connections that can be open at any given time.
• PoolIdleTimeout: Set a limit to how long connections can remain open and idle. If this limit is exceeded, the connection is returned to the pool.
• PoolWaitTime: Set a limit to how long new connection requests should wait for a connection to become available. If this limit is exceeded, the request returns an error. By default, connection requests wait forever for a connection to become available.

Connection Pooling with C1010DataSource

To use the default method for pooling connections, instantiate the C1010DataSource with UseConnectionPooling:

C1010DataSource c1010DataSource = new C1010DataSource();
c1010DataSource.setURL("jdbc:c1010:UseConnectionPooling=true;[email protected];Password=password;LoginURL=https://my.domain.1010data.com/prime-latest");

JDBC Connection Pooling

If you would like to establish a pooled connection using the the JDBC ConnectionPoolDataSource interface, instantiate the C1010ConnectionPoolDataSource with UseConnectionPooling:

C1010ConnectionPoolDataSource c1010PoolDataSource = new C1010ConnectionPoolDataSource();
c1010PoolDataSource.setURL("jdbc:c1010:UseConnectionPooling=true;[email protected];Password=password;LoginURL=https://my.domain.1010data.com/prime-latest");

Closing the Connection Pool

On JRE 1.3 or higher, the connection pool itself automatically closes when the application stops running. You can manually close the connection pool by invoking the close method of the DataSource object.
