This document describes how to perform basic installation of Oracle Enterprise Linux 5.9 with pictorial representations. Download the software V36332-01.iso Oracle Linux Release 5 Update 9 for x86_64 (64 Bit) from Oracle Software Delivery Cloud.

  • Boot from the CD or DVD. At the boot screen, press the “Enter” key to install in graphical mode as shown below.



  • Press the “Tab” key to move focus to the “Skip” key, then press the “Enter” key to continue.



  • On the “Welcome” screen, click the “Next” button.



  • Select the appropriate language, then click the “Next” button



  • Select the relevant keyboard setting, then click the “Next” button.



  • Click choose “Create custom layout” from the dropdown menu and click next. This way you can customize partitions you want to create.



  • You can create custom partitions as shown in the picture.

Here the swap space in Linux is used when the amount of physical memory (RAM) is full. If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space. While swap space can help machines with a small amount of RAM, it should not be considered a replacement for more RAM. Swap space is located on hard drives, which have a slower access time than physical memory. Swap space can be a dedicated swap partition (recommended), a swap file, or a combination of swap partitions and swap files. Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and then an additional 1x physical RAM for any amount above 2 GB, but never less than 32 MB. You can have different partitions like root , home etc.

        A root partition.

This is where “/” (the root directory) is located. In this setup, all files (except those stored in /boot) are on the root partition. A 3.0 GB partition allows you to install a minimal installation, while a 5.0 GB root partition lets you perform a full installation, choosing all package groups.

A Swap partition:

Swapping is necessary for two important reasons.

when the system requires more memory than is physically available, the kernel swaps out less used pages and gives memory to the current application (process) that needs the memory immediately.

a significant number of the pages used by an application during its startup phase may only be used for initialization and then never used again. The system can swap out those pages and free the memory for other applications or even for the disk cache. 

Here you can allocate the swap for normal server as :

Swap space = Double the  RAM size (if RAM < 2GB)

Swap space = Equal to RAM size  (if RAM > 2GB)

        A home partition (at least 100 MB)

To store user data separately from system data, create a dedicated partition within a volume group for the /home directory. This will enable you to upgrade or reinstall Red Hat Enterprise Linux without erasing user data files. Once you are done, click next to proceed



  • Accept the boot loader settings by clicking the “Next” button.



  • Configure the network interface with the appropriate settings. This can be done automatically using DHCP, or manually. If you are not using DHCP, enter the appropriate IP address and subnet mask by clicking edit button and then click next.



  • Select the relevant region by clicking on the map.Click on the “Next” button to proceed



  • Enter a root password for the server, then click the “Next” button to proceed.



  • Select the “Customize now” option and the appropriate installation type and click the “Next” button.



  •  The “Package Group Selection” screen allows you to select the required package groups, and individual packages within the details section.

   1. desktop environment packages:

A desktop environment bundles together a variety of X clients to provide common graphical user interface elements such as icons, toolbars, wallpapers, and desktop widgets. Additionally, most desktop environments include a set of integrated applications and utilities. In Linux, there are so many choices, and this includes the desktop environments and window managers. The most popular desktop environment in Linux are GNOME,Unity, Cinnamon, MATE, KDE, Xfce, and LXDE. If you want the server to have a regular gnome desktop you need to include the following package groups from the “Desktops” section: Desktops, Desktop Platform, Fonts, General Purpose Desktop, Graphical Administration Tools, X Windows System

   2. Application Packages:

Linux includes a huge number of resources commonly used by many programs, such as shared libraries of standard functions, executable files, scripts and standard utilities necessary for the normal working of many programs. The Packages available in this group are supported by your system to develop the programs in the system.

   3. Development packages:

You need to install ‘Development Tools’ group on Linux. These tools include core development tools such as automake, gcc, perl, python, and debuggers which are required to compile software and build new rpm’s.

   4. Servers Packages:

This  provides the packages like  MySQL and PostgreSQL ,Apache web server, Open LDAP and Enterprise Identity Management for the system to support different applications.

   5. Base System Packages :

These packages provides the basic Linux system configuration packages . Choose them according to your requirement.

   6. Cluster Storage  packages:

These packages are required for the storage configuration  while setting up the RAC machines.The Resilient Storage repository includes packages for storage clustering using the global file system (GFS). Make a Selection from the list of packages.

   7. Clustering Packages:

 The  Linux distribution offers the required packages for configuring the cluster. However, the names may differ in each. You need to install lvm2-cluster (in some distributions, the package may be named clvm), the Corosync cluster engine, the  cluster manager (or cman), the Resource Group manager daemon and all their dependencies on all participating servers. Choose the Clustering packages which supports for High availability in Real Application Cluster environment. Once the appropriate clustering packages have been installed on all participating servers, the cluster configuration file must be configured to enable the cluster.

  8. Vitualization Packages:

These packages provide the user-level KVM emulator and disk image manager on the host Linux system.

  9. Language Packages:

The language packages group lists different language packages available for selection. You can select the required language package in which you want the machine to communicate .

When you’ve made your selection, click the “Next” button.



  • On the “About to Install” screen, click the “Next” button. Installation will start.



  • At the end of installation following screen will be displayed. Click “Reboot”.



  • The computer will restart and on the “Welcome” screen, click the “Forward” button and accept the license agreement and proceed with first time setup. This completes the installation and the system is ready for use.
