[Oracle] How to create Oracle RAC using Virtual Box and Vagrant

Hi guys,

In this article I’m going to show you how to create oracle RAC using Virtual Box and Vagrant.

I’m using OS win10 on my pc and I’ve installed these software:

You will also need to download the 19c Grid Infrastructure and Database zip files from here. You’ll see what to do with that in a moment.
    • Grid: LINUX.X64_193000_grid_home.zip
    • Database: LINUX.X64_193000_db_home.zip

You have to place in your favorite area in your filesystem and perform the following command:

$ git clone https://github.com/oraclebase/vagrant.git

Copy the Oracle software under the “…./software/” directory. From the “rac/ol7_19” subdirectory:

dario@elrond MINGW64 /e/vagrant/rac/ol7_19/software (master)
$ ll
total 5809469
-rw-r--r-- 1 dario 197609 3059705302 nov  7 21:52 LINUX.X64_193000_db_home.zip
-rw-r--r-- 1 dario 197609 2889184573 ott 25 09:31 LINUX.X64_193000_grid_home.zip
-rw-r--r-- 1 dario 197609        104 mar  3 21:33 put_software_here.txt

You have to indicate the position of your disks that you want to create:

In my case this is the path:

dario@elrond MINGW64 /e/vagrant/rac/ol7_19/config (master)
$ pwd
/e/vagrant/rac/ol7_19/config

You can edit the file vagrant.yml

asm_crs_disk_1: E:\VirtualBox\shared\ol7_19_rac\asm_crs_disk_1.vdi
  asm_crs_disk_2: E:\VirtualBox\shared\ol7_19_rac\asm_crs_disk_2.vdi
  asm_crs_disk_3: E:\VirtualBox\shared\ol7_19_rac\asm_crs_disk_3.vdi
  asm_crs_disk_size: 2
  asm_data_disk_1: E:\VirtualBox\shared\ol7_19_rac\asm_data_disk_1.vdi
  asm_data_disk_size: 40
  asm_reco_disk_1: E:\VirtualBox\shared\ol7_19_rac\asm_reco_disk_1.vdi
  asm_reco_disk_size: 20


My path is “E:\VirtualBox\shared\ol7_19_rac\asm_crs_disk_1.vdi” you can replace with your path.

Now you can start for build the rac, you can put in your folder where ../ol7_19 and run these commands:
Start the DNS server:

cd dns
vagrant up


Start the second node of the cluster. This must be running before you start the first node.

cd ../node2
vagrant up

Ignore the final “default: Host key verification failed.” message at the end. That’s fine.
Start the first node of the cluster. This will perform all of the installations operations. Depending on the spec of the host system, this could take a long time.

cd ../node1
vagrant up

Connect Rac

You have to use vagrant ssh as below.

dario@elrond MINGW64 /e/vagrant/rac/ol7_19/node2 (master)
$ vagrant ssh
Last login: Thu Mar  5 16:26:52 2020 from 10.0.2.2


$ sudo su -
$ su - oracle 
$ sqlplus as / sysdba

Turn Off RAC

Perform the following to turn off the RAC cleanly.

cd node2
vagrant halt

cd ../node1
vagrant halt

cd ../dns
vagrant halt


Remove Whole RAC

The following commands will destroy all VMs and the associated files, so you can run the process again:

cd node2
vagrant destroy -f

cd ../node1
vagrant destroy -f

cd ../dns
vagrant destroy -f

Keep in touch!
