In this example, I’m creating a simple Oracle Listener service called ‘LISTENER’ using the default port of 1521.
Start the Oracle Net Configuration Assistant (NETCA)
Open an X-Windows session to the server as the ‘oracle’ user.
Set your ORACLE_HOME environment variable appropriately, then start the assistant by running the following:
export ORACLE_HOME=/u01/app/oracle/product/18.104.22.168 $ORACLE_HOME/bin/netca
Once the GUI starts, respond as follows:
- Listener configuration
- Listener Configuration, Listener
- Add (this should be the only option available if there is no listener present already)
- Listener Configuration, Listener Name
- Listener name: LISTENER (you can leave the default ‘LISTENER’ name or chose your own here)
- Listener Configuration, Select Protocols
- TCP selected
- Listener Configuration, TCP/IP Protocol
- Specify port number (1521 being the default)
- Listener Configuration, More Listeners?
- No to configuring another listener
The listener status can be verified by issuing the lsnrctl command like below:
lsnrcrl stat LISTENER LSNRCTL for Linux: Version 22.214.171.124.0 - Production on 19-MAR-2013 21:59:43 Copyright (c) 1991, 2011, Oracle. All rights reserved.

…and the listener configuration will have been written to the following file:
