STILL trying to get Oracle to work on linux -- HELP!!

Question

Hi all-- a dumb newbie problem if I may:
I have Oracle 8.0.5 installed now on Linux (RH5.2).. As per the
install instructions, I created a file /etc/rc.d/init.d/dbora
containing the following:
# 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=/home/oracle/8.0.5.0.0
ORA_OWNER=oracle
if [! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# Start the Oracle databases:
su - $ORA_OWNER -c $ORA_HOME/bin/dbstart &
'stop')
# Stop the Oracle databases:
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut &
esac
In the instructions, it then says:
5) Link dbora by entering:
# ln -s /etc/rc.d/init.d/dbora /etc/rc0.d/K10dbora
# ln -s /etc/rc.d/init.d/dbora /etc/rc2.d/S99dbora
.. this is where I am assuming it is set so that this dbora gets
executed on system boot.. correct?
Anyway, it doesn't work. First of all, I am logged in as root.
Second of all, I am assuming the # signs in there are a mistake
since they are comments in the bash shell. Third of all, if I
just try:
ln -s /etc/rc.d/init.d/dbora /etc/rc0.d/K10dbora
It returns an error saying:
ln: cannot create symbolic link `/etc/rc0.d/K10dbora' to
'/etc/rc.d/init.d/dbora': No such file or directory
So, I tried a 'ls /etc/rc*' and I got:
init.d rc.local rc.sysinit rc1.d rc3.d rc5.d
rc rc.news rc0.d rc2.d rc4.d rc6.d
... so, rc0.d IS there... so, THEN I tried: ls /etc/rc0.d and
got:
ls: /etc/rc0.d: No such file or directory
huh?? why won't this work? does it or doesn't it exist?
Thanks for any help.

A very obnoxious feature of ls in many UNIXes is that
'ls foo*' will show you the contents of the
subdirectory that matches foo* without reminding you that
the file names you are seeing displayed are NOT in your
current directory but, rather, in some subdirectory whose
name happens to begin with foo (you have NO IDEA, precisely,
WHICH directory contents you are seeing.)
For example, in RedHat 5.2, do the following:
cd /etc
ls pp*
What you will (probabably) see displayed APPEARS to be a
list of files in /etc:
chap-secrets ip-down ip-up options pap-secrets
What, IN FACT, you are seeing are files in /etc/ppp.
One way to avoid this confusion is to use the -d option to ls.
'ls -dl pp*' will display one line, showing you the existence
of the directory ppp within /etc, rather than its contents.
As an exercise, also try doing: ls -dF /etc/p*
And, don't forget to thourougly read: man ls
Continuing to the specific problem at hand...

The problem here is [email protected] thinking that ls /etc/rc*
was showing him files in /etc. This was not the case. Rather,
ls /etc/rc* was showing him a list of file names in /etc/rc.d
and rc0.d in in /etc/rc.d, not in /etc.
This further implies that the Oracle instructions (as quoted by
[email protected]) are incorrect. Instead of:
ln -s /etc/rc.d/init.d/dbora /etc/rc0.d/K10dbora
On should instead do:
ln -s /etc/rc.d/init.d/dbora /etc/rc.d/rc0.d/K10dbora
(and similarly for other startups)
(at least this is how the file system on my RedHat 5.2 is
structured -- your milage may vary -- another somewhat
annoying issue with the different UNIXes -- but they all
still make NT amd its registry nonsense look silly)
