#Before Anything:

#  #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 install essential os packages for oracle installation.
 
#set -x
#assure you already configure the yum

#        - stack - max stack size (KB)
#        - cpu - max CPU time (MIN)
#        - nproc - max number of processes
#        - as - address space limit
#        - maxlogins - max number of logins for this user
#        - maxsyslogins - max number of logins on the system
#        - priority - the priority to run user process with
#        - locks - max number of file locks the user can hold
#        - sigpending - max number of pending signals
