Creating an Oracle 12c R2 Physical Standby RAC Database from a
Primary RAC database
A tutorial by Ahmed Baraka
Tutorial Objective
In this tutorial, you will confi gure Oracle D ata G uar d bet ween two Oracle 12 c R2 R AC datab ase s.
Specifically, you will create an Oracle 12 c R2 physical stan dby RAC databa se f ro m a primary RAC
database.
The following diagram is a high level description of the environment that you will create:
Required Knowledge
To und erst and the st eps in this tutori al, you have to h av e the funda mental knowle dg e of the follow i ng:
• Oracle d at ab ase administration
• Oracle RAC administration
• Oracle Data G u ard
• Basics of L i n u x op erati n g system
Tutorial Assumptions
The ste ps are described in this tutorial document with the following assumptions:
• The virt ual m ach in es have b een creat ed usi ng Oracle Vi r tu alBox sof tw are.
• You have four virtual machines. Th e f irst two machines are the nod es of th e pri mary dat aba se.
The other pair is the two n o des of the standby dat aba se.
• The f irst tw o machines are the cluster of t he pri mary dat abas e. It has an Oracle 12c R2 RAC
database installed in it.
