Connecting Clients Outside DCE to Oracle Servers in DCE
The listener.ora File
The
and the addresses at which the listener listens.
In the following example, each element is displayed on a separate line, to show the
file's structure. This is the recommended format, but you do not have to put each
element on a separate line. Be sure to include all the appropriate parentheses, and to
indent if you must continue an element on the next line.
This example assumes the UNIX operating system and the TCP/IP protocol for one
listener, and the DCE protocol for another listener. A single listener can have
multiple addresses. For example, instead of having two separate listeners for
different database instances on a server node, you could have one listener for both,
listening on both TCP/IP and on DCE. However, performance is improved with
separate listeners.
