Defines the network protocol address of the listener.
When a connection is made, the client and the listener are configured with identical protocol addresses. The client uses this address to send the connection request to a particular listener location, and the listener "listens" for requests on this address.
An example address is shown next:
(address=
(protocol=tcp)
(host=sales-pc)
(port=1521))
The protocol parameters in the address are dependent on the protocol selected.
