Configuring the Listener
Using the Oracle Net Configuration Assistant, you can configure a listener easily and quickly.
When you select the Listener Configuration options, you are given the choice to add, reconfigure,
delete, or rename a listener. After selecting the Add option, the first step is to select a listener
name. Figure 15-5 shows the Listener Name screen with the default listener name, LISTENER,
displayed.
After selecting a listener name, you must select a protocol. The default protocol selected is
TCP. Figure 15-6 shows the protocol selection screen.
Once a protocol has been selected, you must designate a port number on which the new
listener will listen.
