Practice makes perfect, but it does not have to be difficult. Please don’t short yourself by not trying to understand what is going on.
This is my third RAC install and I got tired of doing it the hard manual way; hence, decided to script what I can.
ASM will still need to be configured after rackiss:
oracleasm configure -i oracleasm init oracleasm createdisk asm01 /dev/sdb1 ... oracleasm scandisks oracleasm listdisks
Tested Configuration: Linux rac01.localdomain 2.6.39-200.24.1.el6uek.x86_64 using V33411-01.iso on Virtual Box 4.2.12r84980
Modify script based on network configuration for the following:
/etc/resolv.conf /etc/hosts /etc/dnsentries.txt
CUSTOMIZE MINIMAL INSTALL
