As the listener.log on one of my database is growing fast,(like in one day it increases upto 20 MB) everyday i've to delete the log and restart the listener.
Then i tried to make the listener.log off.
For that I tried following steps:

I've set logging_listener=off in listener.ora
also tried to make log_status=off
But still it's growing.
Can u pls provide proper solution to off the listener.log ? After making log level off, whether it cause any effect to database?

Thanks in advance.
