# description: Startup/Shutdown Oracle listener and instance

ORA_HOME="/home/oracle/product/10.2.0/db_1"
ORA_OWNR="oracle"

# if the executables do not exist -- display error

if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
echo "Oracle startup: cannot start"
exit 1
fi

case "$1" in
start)
echo -n "Starting Oracle: "
su - $ORA_OWNR -c $ORA_HOME/bin/dbstart
touch /var/lock/subsys/oracle
echo "OK"
;;
stop)
# Oracle listener and instance shutdown
echo -n "Shutdown Oracle: "
su - $ORA_OWNR -c $ORA_HOME/bin/dbshut
rm -f /var/lock/subsys/oracle
echo "OK"
;;
reload|restart)
$0 stop
$0 start
;;
*)
echo "Usage: $0 start|stop|restart|reload"
exit 1
esac
exit 0

Well, since you're using both RHEL and Oracle, you're paying for support from both of them. Have you called them, to see what's up??

What do your system logs say? How about the Oracle logs? And do you mean the system won't BOOT with that script enabled, or does it boot, but you can't run Oracle without locking up?? Either way, call RHEL or Oracle, since you're in a paid-for, supported environment...they can help you more quickly than we can
