To add this, simply create double the amount of shared disks and select the 'Normal' redundancy option when it is offered. There is no redundancy in the Grid Infrastructure installation or the ASM installation.

This procedure provides a bare bones installation to get the RAC working.

Don't assume you will be able to run this on a small PC or laptop.

Following on from the last point, the VMs will each need at least 4G of RAM, preferably more if you don't want the VMs to swap like crazy.

As you can imagine, this requires a significant amount of disk space, CPU and memory.

The finished system includes the host operating system, two guest operating systems, two sets of Oracle Grid Infrastructure (Clusterware + ASM) and two Database instances all on a single server.

In addition, it allows you to set up shared virtual disks, overcoming the obstacle of expensive shared storage.īefore you launch into this installation, here are a few things to consider.

Using VirtualBox you can run multiple Virtual Machines (VMs) on a single server, allowing you to run both RAC nodes on a single machine. A cheaper alternative is to use virtualization to fake the shared storage. In a production environment, shared storage is often provided by a SAN or high-end NAS device, but both of these options are very expensive when all you want to do is get some experience installing and using RAC. One of the biggest obstacles preventing people from setting up test RAC environments is the requirement for shared storage. If you are comfortable with VirtualBox, Vagrant and RAC you might want to jump straight to the GitHub repository and use the basic instructions here, rather than working through a manual build.
