#Before Anything:
#  If you assure you install all os packages already, you could skip this step.
#  You had batter mount RHEL6 64bit on /mnt
 
#Main Dir
#1 add essential user and group for O11gR2 installation.
#2 modify ~/.bash_profile
#3 modify /etc/sysctl.conf
#4 modify /etc/security/limits.conf
#5 /etc/profile
#6 /etc/pam.d/login
#7 modify /etc/csh.login , which is not shell script
#8 modify the /etc/system-release
#9 install essential os packages for oracle installation.
 
 
#set -x
#assure you already configure the yum
#1 add essential user and group for O11gR2 installation.
