Hi, When I use the svrctl command to check the status of services it shows that listener is up and running but when I use lsnrctl command it is giving following error message. Is it normal behavior when using 2 node RAC cluster on linux AS 4 $ lsnrctl status LSNRCTL for Linux: Version 10.2.0.3.0 - Production on 25-FEB-2008 12:22:00 Copyright (c) 1991, 2006, Oracle.
