The listening with the default port number of 1521 is very simple. After service_names is set up, PMON automatically helps us Register and is very convenient. Registration is not the default port number:

Add the following in $ ORACLE_HOME/network/admin/listener. ora:
LISTENER1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = 172.18.115.78) (PORT = 1590 ))
)
)

(It is best to use IP addresses here)
Set local_listener:
SQL> alter system set local_listener = '(ADDRESS = (PROTOCOL = TCP) (HOST = 172.18.115.78) (PORT = 1590)' scope = both
2;
The system has been changed.

Set service_names:
SQL> alter system set service_names = 'a, B, c, d, diy, OS ';
The system has been changed.

Confirm that the listening process has stopped:
[Oracle @ localhost ~] $ Ps-ef | grep tnslsnr | grep-v grep
Oracle 7312 1 0? 00:00:00/u01/app/oracle/product/11.2.0/dbhome_1/bin/tnslsnr LISTENER-inherit
Oracle 7465 1 0? 00:00:00/u01/app/oracle/product/11.2.0/dbhome_1/bin/tnslsnr listener1-inherit
Stop the listener directly or use the OS command
Here we will directly kill the process:
SQL>! Kill-9 7312


SQL>! Kill-9 7465


SQL>! Ps-ef | grep tnslsnr | grep-v grep

The listening process has stopped.

After a while, PMON registers the listener:
