A JDBC resource (data source) provides applications with a means of connecting to a database.
Before creating a JDBC resource, first create a JDBC connection pool. See To create a JDBC connection pool.
Expand the Resources, then JDBC node.
Select the JDBC Resources node.
Click New from the JDBC Resources page.
Specify the Resource settings as follows:
JNDI Name: Specify a unique name. The JNDI name organizes and locates components within a distributed computing environment similarly to the way that card catalogs organize and represent locations of books in a library. Consequently, the JNDI name becomes an important method of accessing the JDBC resource. By convention, the name begins with the jdbc/ string. For example: jdbc/payrolldb. Don't forget the forward slash.
Pool Name: Choose the connection pool to be associated with the new JDBC resource.
Description: Type a short description of the resource.
Status: If you want the resource to be unavailable, deselect the Enabled checkbox. By default, the resource is available (enabled) as soon as it is created.
Click OK.
