Prerequisite before installation :

Before installing RAC with oracle database,there are some requirements to accomplish this task.Like before installation pdksh and ncurses4 RPMs are installed on every node of RAC. Without these installation, it occur some error during execution of $ORACLE_HOME/root.sh.

To check the installation ,you have to execute this statements :

rpm -q pdksh ncurses4

To install,you need to execute the following :

su - root
rpm -Uvh pdksh-5.2.14-13.i386.rpm ncurses4-5.0-5.i386.rpm

Creating the Shared Configuration File for srvctl :

A configuration file will be required to run the srvctl utility and it would be used to manage the Real Application Clusters instances and listeners to control the database.

For OCFS Filesystems: Creating the shared configuration file for srvctl,you have to execute this command :

#su - oracle
$touch /var/opt/oracle/oradata/orcl/SharedSrvctlConfigFile

For Raw Devices: Suppose I have created a partition of 30MB which is a raw device for the shared configuration file and the device which is located for configuration file is /dev/sda1 which is connected to /dev/raw/raw2,you need to create a soft link for this memory management and run this command :

#su - oracle
$ln -s /dev/raw/raw2 /var/opt/oracle/oradata/orcl/SharedSrvctlConfigFile

Applying Oracle9i Patch Set :

After installation,don't go for Applying any patches without runInstaller means you have apply the runInstaller in $ORACLE_HOME/bin.But before starting runInstaller the following commands would be execute to ignore the runInstaller from any crashing or failure.
And the command is :

#su - oracle
$cd $ORACLE_BASE/oui/bin/linux
$ln -s libclntsh.so.9.0 libclntsh.so
