#
#  This Nagios plugin was created to check remote or local TNS
#  status and check local Database 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.
# 
#
# If you have any problems check that you have the $ORACLE_HOME
# enviroment variable set, have $ORACLE_HOME/bin in your PATH, and
# dont forget about your tnsnames.ora file.  when checking Local
# Database status your ORACLE_SID is case sensitive.
