How to start/stop and check the status of listener.

This doc describes us how to start/stop and check the status of listener.

How to start listener:

Step 1: Find the listener name from listener configuration file. I.e., listener.ora which is under $ORACLE_HOME/network/admin

[oracle@silver ~]$ cd $ORACLE_HOME/network/admin
[oracle@silver admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

OBIEE =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = silver.apps.com)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

Step 2: Start listener

Syntax:  [oracle@silver admin]$ lsnrctl start <Listener Name>

Below is the example.

[oracle@silver admin]$ lsnrctl start OBIEE
