A JDBC resource, also called a data source, lets you make connections to a database using getConnection(). Create a JDBC resource in one of these ways:
Access the Server Manager and choose the Java tab.
Click JDBC Resources.
Click the New button.
Enter the following information:
JNDI Name (required). Enter the JNDI name that application components must use to access the JDBC resource.
Pool Name (required). Select from the list the name (or ID) of the connection pool used by this JDBC resource. For more information, see Creating a New JDBC Connection Pool.
To enable the JDBC resource, select On from the Data Source Enabled drop-down.
If a JDBC resource is disabled, no application component can connect to it, but its configuration remains in the server instance.
Click Apply Changes.
