A feature by which the PMON process--an instance background process--automatically registers information with a listener. Because this information is registered with the listener, the listener.ora file does not need to be configured with this static information.
By default, PMON tries to register information with the default listener that uses TCP/IP on port 1521. You can configure service registration for another listener by configuring the LOCAL_LISTENER parameter in the initialization file and resolve the listener name through a naming method.

For More Information: See Chapter 7, Configuring the Listener, in the Net8 Administrator's Guide to configure the LOCAL_LISTENER parameter. |
Service registration provides the listener with the following information:
This allows the listener to determine how best a client connection request should be serviced.
