simple question regarding LISTENER

hi i have 2 listener listener and listener2
default is listener
i wanted to purge listener logs so i used below steps


$ lsnrctl set log_status off
$ mv listener.log listener.log.old
$ touch listener.log
$ lsnrctl set log_status on

above steps made the logging of listener2 to be stoped and nothing is written in listener.log file of listener2
although in the listener.ora i have added this line and relaod but still it does not generate any log

LOGGING_LISTENER2 = ON
please advice .
