In-Depth Information
While the transition to UEFI is still outstanding, an important change has happened in that 32-bit systems are
dying out. In fact, although you get support for 32- as well as 64-bit Linux, you should not deploy new 32-bit Linux
systems. They simply suffer from too many shortcomings, especially when it comes to memory handling. Oracle
realized this as well, and stopped shipping the database for 32-bit platforms.
The Oracle Linux installation is performed in stages. In the first stage the server to be installed is powered on and
uses a boot medium-the installation DVD or a minimum boot media to start. Alternatively the PXE boot settings can
be used to transfer the minimal operating system image to the server. In the following stage, the installation source as
defined will be used to guide you through the installation process.
Manual Installation
Before exploring ways to automate the Oracle Linux installation using Kickstart let's have a look at the interactive installation
of Oracle Linux 6 first. At the time of this writing, Oracle Linux 6 update 4 was the latest version available for download.
The Oracle Linux media can be obtained from Oracle's self-service portal:
http://edelivery.oracle.com/linux
.
Before you can access the software you need to supply login information using an account with a validated email
address. You also need to agree to the export restrictions and license as is standard with Oracle products. From the list
of available Linux releases to download, choose the current release of Oracle Linux 6 and wait for the download
to finish.
This section assumes the host you are installing to has a DVD-ROM drive to be used for the installation.
(Of course, that DVD_ROM drive can be virtualized). The DVD will be used as the installation source in this section.
In the next section, “Automated installation” further options for installing Oracle Linux over the network are presented.

The advanced installation methods except pxe-booting are out of scope of this topic. More details about
booting from usB and minimal installation media can be found in Oracle's online documentation.
Note
After downloading and verifying the integrity of the DVD ISO image, proceed by burning it to an empty DVD.
Alternatively, make the ISO image available to the virtualized DVD drive on the server. This DVD contains all the
required software to install your server, so the need to juggle CD-ROMs as in previous versions has gone. Ensure
that you can either have access to a boot menu in your server's BIOS or manually set the boot order to start from
CD-ROM/DVD-ROM in the first place. Insert the DVD and power the server on. You should be greeted by the
boot menu as shown in Figure
