Installation on Ubuntu 10.04, Lucid Lynx

Question

Hi all,
this is my first post here. :D
I've just successfully installed on Ubuntu 10.04, Lucid Lynx, and wanted to share the steps that it took and summarize the information I gathered from plenty of Google searches and searches of this forum; maybe they are useful to someone else:
1. Increased swap (more information in English at https://help.ubuntu.com/community/SwapFaq and German at http://wiki.ubuntuusers.de/swap).
2. Installed Oracle Database 10g Express Edition as explained here:
sudo apt-get install libaio1
sudo dpkg -i oracle-xe-universal_10.2.0.1-1.0_i386.deb
sudo /etc/init.d/oracle-xe configureI answered the questions about the ports with the default answers (8080 and 1521) and "no" for starting the database on boot.
After that, I was able to access the database home page at http://127.0.0.1:8080/apex
3. After next reboot with my normal user account "carsten" I was not able to start the database and not able to access http://127.0.0.1:8080/apex
Following thread {message:id=4106998} that is linking to post http://ubuntuforums.org/showpost.php?p=7838671&postcount=4 in the Ubuntu forums, I also:
added myself to the dba group,
sudo usermod -a -G dba carstenmade the listener log writable by the dba group,
sudo chmod g+w /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/network/log/listener.logmade sure the env vars are set for everyone,
sudo ln -s /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/oracle_env.sh /etc/profile.d/oracle_env.shchanged *#!/bin/sh* to *#!/bin/bash* in nls_lang.sh,
sudo gedit /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/nls_lang.shand for being able to login as Ubuntu user "oracle" I set a password (this last step is optional, I needed to login as the "oracle" user for testing, but now it's no longer necessary).
sudo passwd oracle-----
After the next reboot (not strictly required...), logging in again with my normal Ubuntu user "carsten", I can successfully start and stop the database via the gnome Applications menu and start the listener at the terminal with
lsnrctl startWhen both the database and the listener are running, http://127.0.0.1:8080/apex can be accessed in a web browser. Installation complete! :x
This is also the first time that I use an Oracle DB, and I'd be happy about any thoughts or feed-back!
Best regards,
Carsten

Answer 1

well I tried reinstalling because I have double checked and know for certain that I had followed all the installation steps.
Earlier I had put the path export lines in both my .bashrc file and in the /etc/bash.bashrc file and apparently that was allowing "oracle" user to find sqlplus.
Now that I removed that I can't even log in with oracle because it says "command not found"
I tried re-installing with su - instead of sudo because another post at this forum said that is what you are supposed to do.
Now the error I get from sqlplus sys as sysdba is "could not create audit file"
I found the init.ora file and commented out the line audit_file_dest.
I tried changing permissions on the adump directory.
Still get "could not create audit file"
Also I've seen mentioned in a couple of posts that root.sh should be run at the end of the install. What is that and how do you run it? Is that even anything to do with my problem?
Thanks
