Does anyone perform the auto start and shut the database version 8.1.7 using HP_UX 11.0 64 Bits.

I have problem to restart - I checked my /etc/rc.log, there is no error on my S99dbora as follow :

Output from "/sbin/rc2.d/S99dbora start" :
--------------------
Starting NFS Server networking
:
:


My dbora file is as follow :
#!/bin/sh
# Set ORA_HOME to be equivalent to the ORACLE_HOME
# from which you wish to execute dbstart and dbshut
# set ORA_OWNER to the user_id of the owner of the
# ORACLE database in ORA_HOME

ORA_HOME=/oracle
ORA_OWNER=oradb
if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
echo "Oracle startup : cannot start"
exit
fi
case "$1" in
'start')

# Start the Oracle Databases:
# The following command assumes that the oracle login will not prompt
# the user for any values

/usr/bin/su - $ORA_OWNER -c $ORA_HOME/bin/dbstart &
;;
'stop')

# Stop the Oracle Databases:
# The following command assumes that the Oracle login will not prompt
# the user for any values

/usr/bin/su - $ORA_OWNER -c $ORA_HOME/bin/dbshut &
;;
esac

Any error on this file ? Please advice.

This file should created by root user. Am I right ? Anybody can assist me on this ? Thanks !
