JDBC Resource Information
A JDBC resource is a named group of JDBC connections to a database. A JDBC resource denes
the properties used to create a connection pool. Each JDBC resource uses a JDBC driver to
establish a connection to a physical database when the server is started. A pool of connections is
created when the rst request for connection is made on the pool after you start Web Server.
A JDBC-based application or resource draws a connection from the pool, uses it, and when no
longer needed, returns it to the connection pool by closing the connection. If two or more JDBC
resources point to the same pool denition, they use the same pool of connections at run time.
