Listener SCAN Log File.

Oracle DB: RAC 2 Nodes, 11.2.0.3.0

OS: RHEL 6.10

Can someone explain this to me Please? I am in a RAC environment.

====================================

LSNRCTL>

LSNRCTL> set current_listener <listenername>

LSNRCTL> set log_status off

In another window rename the log file. Then return to previous window

LSNRCTL> set log_status on

which will create a new and empty listener.log file which will continue logging. 

===========================================

In a RAC, do I find the <listenername> in the >>> " tnsnames.ora " file?

The current log file is <listener_scan2.log>. it is almost 1GB. I need to get rid of it. and start from fresh. I cannot shutdown the DB.
