Hi Rupen,

1) Make sure that you stop you listener before starting it. Check if it's active (lsnrctl status) and stop it (lsnrctl stop). In some rare cases you may need to clean shared memory.

2) Make sure no other application uses the port you defined for your listener. Check /etc/services and listener.ora. Additionally you can use netstat command to get list of ports currently in use.
