Been testing on a Linux box with same version 9.2.0.4

What I did:
Code:
-	Changed /etc/oratab file to: DEV1:/opt/ora9/product/9.2:Y
-	Create file /etc/init.d/dbora
#!/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=/opt/ora9/product/9.2
ORA_OWNER=oracle

if [! -f $ORA_HOME/bin/dbstart]
Configuration Tasks to Perform as the root User
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

	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

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

- chmod 755 dbora
- ln -s /etc/init.d/dbora /etc/rc0.d/K10dbora
- ln -s /etc/init.d/dbora /etc/rc3.d/S99dbora
