This is to share the screenshot of the oracle installation in my mandriva 2009 (Free). The installation is very simple. Download the oracle installation jar from oracle.com. It has only one dependency, considering mandriva 2009, which is libaio.jar. See whether it is coming with Mandriva, or else download from the web. thats it. then install the RPMs.
Once RPMs are installed, database need to be configured. Issue the following command to configure the database.
This will take you to a text wizard asking the system username, password etc and complete your installation process. See the screenshot below.
Try to login to your oracle server with the web interface
ofcourse you have the option to change the port also.
