After a server reboot - How to ensure Database starts automatically

Question

Hi all,
I have an Oracle9i database on Solaris 8. The Solaris server is a bit unstable at the moment ans sometimes reboots itself. I set the last column in the oratab file to Y (on Solaris, it's in /var/opt/oracle/oratab), but Oracle still doesn't automatically start after a reboot.
Does anyone know of any other settings that will enable the DB to auto-restart after a reboot?
Regards

For Auto Startup and Shutdown of Database and Listener
1)
Login as root and modify /etc/oratab file and change last character to Y for apropriate database.
ORCL:/opt/oracle/111:Y
-------->> before changing it should look like ORCL:/opt/oracle/111:N
2)
As root user create new file "oracle" (init script for startup and shutdown the database) in /etc/init.d/ directory with following content:
#!/bin/bash
# oracle Init file for starting and stopping
# Oracle Database. Script is valid for 10g and 11g versions.
# chkconfig: 35 80 30
# description: Oracle Database startup script
# Source function library.
. /etc/rc.d/init.d/functions
ORACLE_OWNER="oracle"
ORACLE_HOME="/opt/oracle/111"
case "$1" in
start)
echo -n $"Starting Oracle DB:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"
echo "OK"
stop)
echo -n $"Stopping Oracle DB:"
su - $ORACLE_OWNER -c "$ORACLE_HOME/bin/dbshut $ORACLE_HOME"
echo "OK"
echo $"Usage: $0 {start|stop}"
esac
3)
Execute (as root) following commands (First script change the permissions, second script is configuring execution for specific runlevels):
chmod 750 /etc/init.d/oracle
chkconfig add oracle level 035
