Uninstall Oracle XE

Configuring enterprise product is really hard. Although I have successfully start up Oracle listener, but I still failed to configure a database in Oracle. No more wasting time on this configuration work, thus I had decided to un-install it.

First check oracle is installed:

rpm -qa | grep oracle

If there is an output, then un-install it:

su -c 'rpm -e oracle-xe-11.2.0-1.0.x86_64'

Not there yet, some files need manual instruction:

rm -rf /u01
rm /etc/oratab

Oracle is un-installed successfully!
