Listener=(description=
(address_list=
(address=(protocol=tcp)(host=192.168.0.200)(port=1521))
(address=(protocol=ipc)(key=extproc))))
Sid_list_listner=
(sid_list=
(sid_desc=
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1)
(sid_name=nijam))
)
Then save the file.

[oracle@nijam admin]$lsnrctl
Lsnctl>start    --->a starts the listener with the name specified.will be used.
Lsnrctl>stop   --->a stop the listener.
