JDBC ResourceInformation
AJDBC resource is a named group of JDBC connections to a database. A JDBC resource denes
theproperties used to create a connection pool. Each JDBC resource uses a JDBC driver to
establisha connection to a physical database when the server is started. A pool of connections is
createdwhen the rst request for connection is made on the pool after you start Web Server.
AJDBC-based application or resource draws a connection from the pool, uses it, and when no
longerneeded, returns it to the connection pool by closing the connection. If two or more JDBC
resourcespoint to the same pool denition, they use the same pool of connections at run time.
