-# This Nagios plugin was created to check remote or local TNS
-# status and check local Database status.
+# This Nagios plugin was created to check Oracle status
#
-# Add the following lines to your object config file (i.e. commands.cfg)
-# command[check-tns]=/usr/local/nagios/libexec/check_ora 1 $ARG$
-# command[check-oradb]=/usr/local/nagios/libexec/check_ora 2 $ARG$
-#
-#
-# Usage:
-# To check TNS Status: ./check_ora 1 <Oracle Sid or Hostname/IP address>
-# To Check local database: ./check_ora 2 <ORACLE_SID>
-#
-# I have the script checking for the Oracle PMON process and
-# the sgadefORACLE_SID.dbf file.
