When starting the Oracle listener, it is important to take note of the following points:

Ensure that the listener name, listener address, and listener port are configured correctly in the listener configuration file (listener.ora).
Starting the listener with the correct permissions typically involves using the Oracle software owner (usually the oracle user) to start the listener.
Make sure that the log file path for the monitoring program is correct and has enough space.
Check the network connection to ensure that the firewall or network devices are not blocking communication between the listener and the database.
Before starting the listener, it is necessary to stop any currently running listener program to avoid port conflicts.
You can use the lsnrctl command to start the listener and check its status with the lsnrctl status command.
After starting the listener program, promptly review the program’s log files to check for any potential issues or error messages.
