Installing 11gR2 Real Application Clusters on Oracle Enterprise Linux 4 x86-64 (64 bit)
Installing Real Application Clusters
This document provides a step by step guide to, installing Oracle 11gR2 Real Application clusters on Oracle Enterprise Linux 4, x86-64 (64 Bit).
Keep in mind, this is a test installation and hence does not follow some of the best practices for installing oracle real application clusters (eg: use a separate o/s user for oracle grid infrastructure, have at least 3 voting disks etc...).
This document assumes that you have followed the document 11gR2RacInstall-gridinfra to install and configure the oracle grid infrastructure. In this document I have the steps to do the Real Application Clusters Install.
Installing 11gR2 Real Application Clusters
Unzip the Oracle Enterprise Edition Software in the staging directory
Login as the oracle user
cd <staging directory>/database
./runInstaller
I skipped the Oracle Configuration manager setup (This being a test install).
Click Next on the screen above.
Choose to "Install database software only"
In the above screen, Choose "Real application cluster database installation" and all the nodes in the cluster, and click Next.
Click Next on the screen above.
In the screen above, Choose to install "Enterprise Edition", and click Next.
If you want to choose the options you want to install, you can click on "Select options", and choose the options you want to install (Screenshot below)
In the screen above, Choose the Oracle Base directory and the Oracle Software Home directory.
Click Next to continue.
In the screen above, choose the osdba and osoper groups as "dba" and click Next.
In the above screen i chose to ignore the missing pre-requisites (because i know i have enough swap space for a test system, and i had not used the -x flag for ntp).
Click Next.
In the summary screen above, click Finish to continue with the installation.
The installer shows you the progress of the installation.
At the end, the installer will prompt you to run the root.sh script (This time from the database home directory).
Login as root on the servers and execute the root.sh script, and then click Ok, on the screen above.
Oracle Enterprise Edition, Real Application clusters is now installed on your cluster.
