Starting Oracle XE on linux by /etc/init.d/oracle-xe start

Question

Hello,
I installed Oracle Database 10g Express Edition on a Linux Ubuntu 7.04 (feisty)
following official installation instructions found here
http://www.oracle.com/technology/software/products/database/xe/files/install.102/b25144/toc.htm#BABCEAHD
but I noticed a weird behavior.
The installation process was ok.
The configuration process (/etc/init.d/oracle-xe configure) was also ok.
I set everything on default except for the “starting on boot” option I choose NO, because the instructions let me understand that I can start the service manually by the command:
$ /etc/init.d/oracle-xe start
The configuration process at the end also started the service well, so I could test my new oracle installation on my web browser following the url http://127.0.0.1:8080/apex
Everything went fine... but...
On the next boot I wanted to start my oracle so I typed
sudo /etc/init.d/oracle-xe start
but nothing happened and the server didn't go up.
Looking into to script /etc/init.d/oracle-xe
we can find this switch
case "$1" in
start)
     if test -f "$CONFIGURATION"
     then
          if test "$ORACLE_DBENABLED" != "true"
          then
               exit 0
          fi
     else
     echo "Oracle Database 10g Express Edition is not configured. You must run
'/etc/init.d/oracle-xe configure' as the root user to configure the database."
          exit 0
     fi
     start
this means that if you chose NO (N) for the “starting on boot” option on the configuration process (NB this choice put false in the env variable ORACLE_DBENABLED) you can't start the dbms by this script.
I try comment the few lines
     then
          #if test "$ORACLE_DBENABLED" != "true"
          #then
          #     exit 0
          #fi
     else
and this time the server starts well.
So I deduced that something was wrong with the script and the official installation instructions.

Answer 1

Yes... Thank you.
But I saw the problem could to be simple avoided using the options
enable/disable for the script /etc/init.d/oracle-xe,
If you choose not to start oracle at boot time, you can start it
manually by the sequence
/etc/init.d/oracle-xe enable
/etc/init.d/oracle-xe start
then when you want to stop it
/etc/init.d/oracle-xe stop
/etc/init.d/oracle-xe disable
by this last command we don't make oracle restart
at the next system boot.
I think it would be a good thing to update the reference
documentation at
http://www.oracle.com/technology/software/products/database/xe/files/install.102/b25144/toc.htm#BABCEAHD
to explain this situation better.
