How to automatically startup Oracle on SUSE Linux

Question

I have Oracle 11g installed on a server running SUSE Linux 11. I followed the official Oracle instructions to try to set up Oracle for automatic startup.
My /etc/oratab file contains the following:
sidname:/opt/oracle/product/11gR2/db:Y
I created a /etc/init.d/dbora file, which contains the following:
#! /bin/sh  -x
# Change the value of ORACLE_HOME to specify the correct Oracle home
# directory for your installation.
ORACLE_HOME=/opt/oracle/product/11gR2/db
# Change the value of ORACLE to the login name of the
# oracle owner at your site.
ORACLE=oracle
PATH=${PATH}:$ORACLE_HOME/bin
HOST=`hostname`
PLATFORM=`uname`
export ORACLE_HOME PATH
if [ ! "$2" = "ORA_DB" ] ; then
   if [ "$PLATFORM" = "HP-UX" ] ; then
      remsh $HOST -l $ORACLE -n "$0 $1 ORA_DB"
      exit
   else
      rsh $HOST -l $ORACLE  $0 $1 ORA_DB
      if [ "$PLATFORM" = "Linux" ] ; then
          touch /var/lock/subsys/dbora
      fi
      exit
   fi
fi
case $1 in
'start')
        $ORACLE_HOME/bin/dbstart $ORACLE_HOME &
'stop')
        $ORACLE_HOME/bin/dbshut $ORACLE_HOME &
        echo "usage: $0 {start|stop}"
        exit
esac
exit
Then I ran the following commands:
chgrp dba /etc/init.d/dbora
chmod 750 /etc/init.d/dbora
ln -s /etc/init.d/dbora /etc/rc.d/rc0.d/K01dbora
ln -s /etc/init.d/dbora /etc/rc.d/rc3.d/S99dbora
ln -s /etc/init.d/dbora /etc/rc.d/rc5.d/S99dbora
shutdown -r now
After restarting, Oracle was not running:
server:~ # ps -fea | grep ora
root      2681  2563  0 21:18 ?        00:00:00 hald-addon-storage: no polling on /dev/fd0 because it is explicitly disabled
root      2688  2563  0 21:18 ?        00:00:00 hald-addon-storage: polling /dev/sr0 (every 2 sec)
root      4491  4333  0 21:19 pts/1    00:00:00 grep ora
server:~ # ps -fea | grep lsnr
root      4493  4333  0 21:19 pts/1    00:00:00 grep lsnr
Oracle runs fine after I start the instance (by logging into sqlplus as "sys as sysdba" and issuing the "startup" command) and listener. But it won't start up automatically after restarting the server. Why is that?

I got it working.  I had to change the dbora file to look like this:
#! /bin/sh  -x
# Change the value of ORACLE_HOME to specify the correct Oracle home
# directory for your installation.
ORACLE_HOME=/opt/oracle/product/11gR2/db
# Change the value of ORACLE to the login name of the
# oracle owner at your site.
ORACLE=oracle
PATH=${PATH}:$ORACLE_HOME/bin
export ORACLE_HOME PATH
touch /var/lock/subsys/dbora
case $1 in
'start')
        su - $ORACLE $ORACLE_HOME/bin/dbstart $ORACLE_HOME &
'stop')
        su - $ORACLE $ORACLE_HOME/bin/dbshut $ORACLE_HOME &
        echo "usage: $0 {start|stop}"
        exit
esac
exit
Then I had to delete the listener.log and startup.log files in $ORACLE_HOME because they were incorrectly owned by root.
