Database Services

The Database Services tab enables you to specify the database service(s) for which the listener is to receive connect requests. The listener needs this information to connect a client to the database.

An Oracle release 8.1 instance use dynamic service registration to inform the listener about its database service(s). Oracle7 and Oracle8 release 8.0 databases and Oracle Enterprise Manager tools require static service configuration in the listener.ora file.

Choose Add Database to add database service information.
