Ubuntu Linux Remove Oracle Express Edition

Author: Vivek Gite Last updated: April 24, 2009 10 comments

I know how to install Oracle XE on Debian / Ubuntu Linux. But, how do I remove Oracle Express edition under Ubuntu Linux?

You can use apt-get command to remove / delete Oracle express edition server from the Debian / Ubuntu Linux.

I think you may have meant rather: sudo apt-get remove oracle-xe

Also this works (not forgetting the client package): dpkg -r oracle-xe oracle-xe-client

It’s apt-get remove oracle-xe-universal now. At least it is (or rather, ‘was’) on my Jaunty installation.

I am currently stuck with oracle on my system in order to be able to log in.

both apt-get and synaptic removal options leave something in Ubuntu 10.04 that is still looking for oracle files that do not exist after removal. It’s not the .bashrc because I removed .bashrc entries for the oracle path. Still Ubuntu fails to load gdm with an error about not finding the oracle files.

Anyone else had this problem and know the fix can you please add it to this post.

Thank you

@Sathish apparently something still gets left behind even when I use the option to completely remove in synaptic. It’s been a while since then and maybe some updates have fixed the issue so I’ll try it again this weekend and see if it works. I’ve just been using my Ubuntu system with oracle installed and just never using it. Other than the oracle listener running in the background I don’t think it slows my system by being there. I’m actually working on learning oracle and linux by setting up the unbreakable linux from oracle on it’s own server so I don’t care about this one on my Ubuntu. Still it seems silly to have to just leave it so the rest of the OS can operate.

I’ll try uninstalling it again later today and see what happens.

@lan, thank you. I did something wrong during the setup. Now Ubuntu doesn’t able to recognize any commands.
commands like /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/sqlplus are giving No such file or directory… no issues with permissions…
I’d similar problem in my laptop; After going through many forums,, finally I re-installed the OS itself.

In some new versions of Ubuntu, apt-get remove will not work. We have to use the underlying dpkg of apt-get:

sudo /etc/init.d/oracle-xe stop
sudo dpkg -P oracle-xe-universal

It should remove all config files and /usr/lib/oracle stuff (unless some files, dirs are held by some process).
To make sure clean uninstallation,

rm -rf /usr/local/oracle

Then reboot

sudo shutdown -r 0

Now it should be done! You can re-install Oracle xe again:

sudo dpkg -i oracle-xe*.deb
sudo /etc/init.d/oracle-xe configure

good luck,
