1.0 Introduction

I will confess right at the outset that I am very definitely more of a Suse or Red hat/Fedora man than an Ubuntu one, and that my familiarity with the Debian-based distro that has recently been garnering all accolades is merely skin-deep -so long-time Debian users should not get too upset if they see me doing hilariously clumsy things in the course of this article! Nevertheless, I wanted to document how to install Oracle 10g Release 2 onto Ubuntu 5.10 (the "Breezy Badger" release) precisely because Ubuntu appears to have a lot of momentum behind it in the 'Linux press', and appears to me at least to be well on the way to becoming the distro against which all others are measured, at least in mindshare terms.

So, despite my usual 'house rule' that nothing but "Enterprise-class" distros get the 'how to install Oracle' treatment (because they're the only distros you're going to meet in a real-world server room); and despite my fondness for all things Suse; this article will indeed explore how you go about performing an Oracle 10g Release 2 installation onto the hottest 'home distro' of the moment.

I should mention that I am aware that in slightly less than four weeks' time, the article will be out of date, because the next release of Ubuntu (version 6.04 "Dapper Drake") is due out in May 2006. But you can't, of course, keep waiting for the latest release of everything, otherwise you'd never end up writing anything! So all I can do is promise to look at installing Oracle onto the new Ubuntu when it's finally ready, and if there are any major changes to the article required at that time, I'll incorporate them somehow.

2.0 Obtaining Ubuntu

Ubuntu can be downloaded for free from the official Ubuntu download site. It comes as a single CD-sized ISO image, about 600MB in size (there are also BitTorrent downloads available). Make sure you get the 5.10 release, and make sure you get the 'Install' flavour of the release, not the 'Live' flavour (Live CDs are a fully-working distro that runs directly off a bootable CD, allowing you to test out the distro, but is no actually installed onto a hard disk -which would be a bit of a show-stopper as far as getting Oracle to run long-term is concerned!)

Ubuntu's hardware requirements are fairly minimal (officially, 128MB of RAM and 2GB of disk space for a desktop system) but Oracle's are not, so make sure your PC actually has at least 512MB of RAM and 6GB of free hard disk space, minimum. Ideally, you will want to install Oracle onto a fresh Ubuntu installation, since "pre-loved" installations will quite probably have a pile of library and version incompatibilities that will play havoc with Oracle. This article is certianly going to use a completely fresh Ubuntu 5.10 installation, anyway, straight off the CD and without any prior patching or updating. It's strongly recommended that you do likewise for repeatable, predictable results.

3.0 Installing Ubuntu

The Ubuntu installation process is a peculiar affair for anyone brought up on Fedora, Red Hat or Suse installations! It's done entirely with a command-line interface (though this particular command line has been prettified and tarted up remarkably well), and there aren't an awful lot of choices to make: for the most part, you just keep on selecting the 'Continue' option, and leave everything set to the default offering. This approach is certainly convenient, but it also brings trouble in the form of a default configuration that gets its IP address via DHCP -and that's a no-no as far as Oracle is concerned (and here's an article that explains why). Still, dynamically-assigned IP addresses can be sorted out once the installation is finished, so it's not the end of the world if one gets implemented to begin with. We'll similarly have to deal with the fact that nowhere in the default Ubuntu installation process do you get to choose which packages you want included in the installation: it is instead an all-or-nothing affair, and you tend to get merely what you're given!

For anyone wondering how I went about installing Ubuntu on my PC, I have a short Flash movie showing all the gory details, and you're welcome to view it at your leisure

For those without Flash, the important points of my installation were to perform a default Ubuntu install, let the installer wipe the entire hard disk and partition it as it likes, and create myself as a non-root user.
