Oracle 11g Software Installation on Linux—CentOS-5

　　Introduction
　　This paper takes a look at installing oracle 11g (11.1) on Linux (CentOS-5).You can read about CentOS at www.centos.org and be assured of its’ Enterprise-class quality. This paper will use oracle’s Quick Installation Guide for Linux x86 as its’ guide—noting where additional information may be obtained but getting oracle installed on Linux as fast as possible. We at thecheapdba.com have years of experience installing oracle—starting back with oracle 7. We will point out best practices so that you end up with a reliable database that provides exceptional performance. We will occasionally re-visit, edit, and post additions to this paper as we find further configuration best practices.
　　This paper will not cover the installation of CentOS-5 as that can be acquired through the CentOS website and additional Linux guides. We will however point out those alterations to the Linux environment that pertains to getting oracle installed.
　　Our goal is to provide you with the steps to properly install the oracle 11g software without having to read oracle’s installation guide from front to back cover. We will provide you the commands to execute (just cut-n-paste) and the desired outcome of those commands. If you get something other than what is expected it would be time for you to re-visit earlier steps in this process. So hold on, here we go.
　　It is assumed that the installer of oracle software has access and is running on an X Window System workstation. Please consult X Server documentation if you need help. We at thecheapdba.com typically will use cygwin ( www.cygwin.com ) for all interfacing with our Linux distribution. It has an X Window System that works quite well—and as we always like is free.
