A Java DataBase Connectivity (JDBC) resource (data source) provides applications with the means of connecting to a database. Typically, the administrator creates a JDBC resource for each database accessed by the applications deployed in a domain; however, more than one JDBC resource can be created for a database.
Applications get a database connection from a connection pool by looking up a data source on the Java Naming and Directory Interface (J.N.D.I.) API tree and then requesting a connection. The connection pool associated with the data source provides the connection to the application.
The JDBC Resources page displays a list of resources that have been created on the application server. For each resource, the following information is provided:
The JNDI name associated with the resource.
True if the resource is enabled, or false if the resource is disabled.
The JDBC connection pool associated with the resource.
A description of the application.
