Create your own RAC Cluster with VirtualBox + Vagrant

Hi Arthur, before you start your journey, is important to have a good test environment where we can try any endeavour we please.

As important as having an stable Test system is the possibility to recreate it on few simple steps.

This chapter of our guide will show you how to make Marvin create a Oracle RAC on Oracle Linux 7 and with 18C GRID + 18C DB (CDB + 1 PDB).

Try to be patient, and remember that Marvin will complain and wont take any enjoyment for this or any task, but I'm sure he will eventually comply

Let's go and start exploring this new place!!

We will be using Tim Hall RAC creation process, so please make sure you first visit his guide to get the necessary software and tools in your system before we start the process:

If you want to know more about Vagrant, please visit following links:

https://oracle-base.com/articles/vm/vagrant-a-beginners-guide
https://semaphoreci.com/community/tutorials/getting-started-with-vagrant

You will need to download 18C DB and Grid Software:

https://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle18c-linux-180000-5022980.html

In our case, we are running Vagrant and VirtualBox in Linux, but you can do this in Windows or Mac, will just change a bit on which commands to use, but the general idea is the same.

System requirements are the following:
-- At least 6GB of RAM (but 10GB are recommended) per each DB node (2 nodes on this installation)
-- At least 1GB of RAM for the DNS node
-- Around 150GB of Space on disks (80GB for default DATA diskgroup creation, but you can reduce the size of the disks if you need to)

19c Is here already

This guide was created to have 18c Tests cluster, but you can already
execute the same process to have your new 19c system running. Tim Hall
already updated his repository with the new version
https://github.com/oraclebase/vagrant

The steps are the same, you just need to download 19c software and
make sure you use the new folder "vagrant/rac/ol7_19/" instead of
"vagrant/rac/ol7_183"

More info in his Blog post:
https://oracle-base.com/blog/2019/02/28/oracle-database-19c-installations-rac-data-guard-and-upgrades/

First, lets clone Tim's Git repository (a lot of good stuff there.. not only this RAC):

arthur@marvin:~/# git clone https://github.com/oraclebase/vagrant.git

Doing this, we will get the following tree Structure into our server:

arthur@marvin:~/# cd vagrant/

Make sure you copy the 18C DB and Grid Software to the RAC node1:

arthur@marvin:~/vagrant# cd rac/ol7_183/node1/software/
arthur@marvin:~/vagrant/rac/ol7_183/node1/software# pwd
/home/arthur/vagrant/rac/ol7_183/node1/software
arthur@marvin:~/vagrant/rac/ol7_183/node1/software# ls -lrth
total 9.3G
-rw-r--r--. 1 arthur arthur 4.3G Jul 25 19:33 LINUX.X64_180000_db_home.zip
-rw-r--r--. 1 arthur arthur 5.1G Jul 25 19:41 LINUX.X64_180000_grid_home.zip
-rw-rw-r--. 1 arthur arthur  104 Jan 11 22:27 put_software_here.txt
arthur@marvin:~/vagrant/rac/ol7_183/node1/software#

Now that we have that, we need to modifyt he RAC shared disks location. To do that, modify the file vagrant.yml inside the folder 'rac/ol7_183/shared_disks/config/'.

In my case, I just left them in "/home/arthur/rac_shared_disks", just make sure you have enough space (each disk disk is 20GB by default, but you can just change it changing "asm_disk_size" variable in that same file)

arthur@marvin:~/vagrant/rac/ol7_183/shared_disks# cat ../config/vagrant.yml
shared:
  box: bento/oracle-7.6
  non_rotational: 'on'
  asm_disk_1: /home/arthur/rac_shared_disks/asm_disk_1.vdi
  asm_disk_2: /home/arthur/rac_shared_disks/asm_disk_2.vdi
  asm_disk_3: /home/arthur/rac_shared_disks/asm_disk_3.vdi
  asm_disk_4: /home/arthur/rac_shared_disks/asm_disk_4.vdi
  asm_disk_size: 20

dns:
  vm_name: ol7_183_dns
  mem_size: 1024

Ok, lets start the fun part and get the RAC created and deployed!

One of the advantages of using Vagrant, is that will check each box and install any required service or even OS if needed, so if you need Oracle Linux 7.6, will download it (if available) and will do the same with each component needed
Is important to follow the following order so everything gets completed correctly

To start the rac all we have to do is the following in this same order:

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

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. On one of my servers it took about 3.5
hours to complete.

cd ../node1 vagrant up

However, since the first the first deployment will take some time, I
recommend you to use the following command, so you also get a log to
check in case there is any issue:

arthur@marvin:~/vagrant/rac/ol7_183/node2# nohup vagrant up &

Start first the DNS server. Notice how Vagrant will download Oracle Linux image directly, avoiding any extra steps downloading ISO images. Also, how will install any necessary packages like dnsmasq in this case:

arthur@marvin:~/vagrant/rac/ol7_183/dns# nohup vagrant up &

And finally, lets start node1. This will perform all of the installations operations. As you can see below, it took ~3.5 hours for this first start, but that wont be the case on next reboots since all the installation tasks were completed

Node1 failure

If node1 creation and CRS/DB deployment fails for any reason (lack of
space, session disconnected during process.. etc..) is better to
destroy both nodes and start again the process starting node2 and then
node1.

If not, you may face issues if you retry the process again just for
node1 (see how to destroy each component at the end of this guide)

Lets check the rac
If you are in the directory from where we have started the VM, you can simply use "vagrant ssh" to connect to it:

Vagrant SSH

You should now be able to see the RAC resources running (allow 5-10 minutes for CRS/DB to start after the cluster deployment is completed)

[oracle@ol7-183-rac1 ~]$

If you want to check the current status of the VMs, you can use the following commands from our host marvin:

arthur@marvin:~# vagrant global-status
id       name    provider   state   directory
---------------------------------------------------------------------------
40d79c9  default virtualbox running /home/arthur/vagrant/rac/ol7_183/dns
94596a3  default virtualbox running /home/arthur/vagrant/rac/ol7_183/node2
87fd155  default virtualbox running /home/arthur/vagrant/rac/ol7_183/node1

The above shows information about all known Vagrant environments
on this machine. This data is cached and may not be completely
up-to-date (use "vagrant global-status --prune" to prune invalid
entries). To interact with any of the machines, you can go to that
directory and run Vagrant, or you can use the ID directly with
Vagrant commands from any directory. For example:
"vagrant destroy 1a2b3c4d"
arthur@marvin:~#



arthur@marvin:~# VBoxManage list runningvms
"ol7_183_dns" {43498f5d-85b4-404e-8720-caa38de6b496}
"ol7_183_rac2" {21c779b5-e2da-44af-a121-89a8c2bfc3c6}

If you don't want to use "vagrant ssh" you can use "vagrant port" and check the different ports the VMs has open and connect using ssh directly. This also allows you to connect using a different user than vagrant

(User/Pass details are in vagrant/rac/ol7_183/config/install.env)

arthur@marvin:~/vagrant/rac/ol7_183/node1# vagrant port
The forwarded ports for the machine are listed below. Please note that
these values may differ from values configured in the Vagrantfile if the
provider supports automatic port collision detection and resolution.

    22 (guest) => 2201 (host)
  1521 (guest) => 1521 (host)
  5500 (guest) => 5500 (host)

In case you want to delete the Cluster, instead of deleting the whole directory, you can just "destroy" each component

arthur@marvin:~/vagrant/rac/ol7_183# du -sh *
8.0K    config
80K     dns
22G     node1
22G     node2

arthur@marvin:~/vagrant/rac/ol7_183/node2# vagrant destroy -f
==> default: Destroying VM and associated drives...
arthur@marvin:~/vagrant/rac/ol7_183/node2#


arthur@marvin:~/vagrant/rac/ol7_183# du -sh *
8.0K    config
80K     dns
22G     node1
28K     node2

Well, that's it for this guide, at least for now.

I'm sure if you build one of this, you will be able to find more interesting things on it and like every good destination, we will end up coming back and add some extra nuggets on how personalize the Cluster to our taste.
