The listener must be configured with one or more protocol addresses. The listener receives connection requests from clients configured with the same addresses.
To configure a protocol address for the listener:
When configuring the listener to listen on TCP/IP for Net8 clients, you should choose the default port or 1521. If you do not, you must configure the LOCAL_LISTENER parameter in the initialization parameter file and resolve the listener name through a naming method. For further information about configuring non-default port, see Chapter 7, Configuring the Listener, in the Net8 Administrator's Guide.
