Here's a solution to Oracle Startup / Shutdown on RH6

Question

I had a hard time getting Red Hat 6.0 to startup and shutdown
Oracle properly. Red Hat's slick rc scripts look cool, but hide
the problem unless you do some serious reading.
This script still isn't perfect, mainly because it can't
shutdown if oracle users are still logged in. This is a problem
with the dbshut scripts. I try to avoid hacking Oracle's bin
directory, but if you really want to go down, change the
shutdown lines to shutdown immediate. Oracle, please provide an
option to dbshut to fix this! :-)
My changes to the book version fix the following:
1. It creates a file /var/log/dbora to log the startup output to
give you some visibility after the fact.
2. Creating the /var/lock/subsys/dbora file after startup makes
the shutdown work. Otherwise rc won't even try. Deleting it
makes changes between run levels work right.
3. The startup is NOT backgrounded so that if you are watching
it boot you can at least gauge the time it takes before the
startup.
4. It starts the listener too.
5. It checks the log file for startup errors and makes the
screen say FAILED in red if it sees any errors.
5. It allows dbshut some time to finish before unmounting. My
dual xenon machine goes down do fast dbshut wouldn't finish
downing both of my sids.
# dbora -start/stop Oracle
#action
ORA_HOME=/home/oracle;export ORA_HOME
ORA_OWNER=oracle;export ORA_OWNER
if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >
/var/log/dbora.log
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>
/var/log/dbora.log
touch /var/lock/subsys/dbora
'stop')
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut &
sleep 15
rm -f /var/lock/subsys/dbora
esac
if egrep -q "ORA-" /var/log/dbora.log; then
exit -1
else
exit 0
fi
Note that the links prescribed by the book are also incorrect.
Linux's rc levels do NOT run sequentially. Therefore, you need a
start and stop on the same level. If you want to save some RAM
on the serve by not running X, you'll want level 4 scripts and
level 5 scripts. So, Create all these links (as ROOT).
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc4.d/K10dbora
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc4.d/S99dbora
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc5.d/K10dbora
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc5.d/S99dbora
To be really safe also create these links. This way there is no
escaping a proper oracle shutdown.
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc0.d/K10dbora
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc1.d/K10dbora
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc2.d/K10dbora
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc3.d/K10dbora
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc6.d/K10dbora
Have fun!

It isn't necessary to create the symlinks for the rc scripts
manually--that's what the "chkconfig" command is for.
