SCAN listener logs – where are they?

These are a bit of a pain as their location isn’t intuitive. So to remind me where they are:

Login to the server(s) as the grid owner and check the scan listener status. This will show you the location of the listener log. cd to just below the diag directory and you’re off!:

server-name:/u01/grid>ps -ef | grep SCAN
 grid 8542 8282 0 10:20 pts/0 00:00:00 grep SCAN
 grid 9349 1 0 Mar07 ? 00:07:33 /u01/app/11g/grid/bin/tnslsnr LISTENER_SCAN1 -inherit

server-name:/u01/grid>lsnrctl status LISTENER_SCAN1
