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. A cheaper alternative is to use a FireWire disk enclosure to allow two machines to access the same disk(s), but that still costs money and requires two servers. A third option is to use virtualization to fake the shared storage. Using VirtualBox you can run multiple Virtual Machines (VMs) on a single server, allowing you to run both RAC nodes on a single machine.

In addition, it allows you to set up shared virtual disks, overcoming the obstacle of expensive shared storage. Before you launch into this installation, here are a few things to consider. • 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. As you can imagine, this requires a significant amount of disk space, CPU and memory. • Following on from the last point, the VMs will each need at least 3G of RAM, preferably 4G if you don't want the VMs to swap like crazy. As you can see, 11gR2 RAC requires much more memory than 11gR1 RAC.

Don't assume you will be able to run this on a small PC or laptop. • This procedure provides a bare bones installation to get the RAC working. There is no redundancy in the Grid Infrastructure installation or the ASM installation. To add this, simply create double the amount of shared disks and select the 'Normal' redundancy option when it is offered.

Of course, this will take more disk space. • During the virtual disk creation, I always choose not to preallocate the disk space. This makes virtual disk access slower during the installation, but saves on wasted disk space. The shared disks must have their space preallocated. • This is not, and should not be considered, a production-ready system.

It's simply to allow you to get used to installing and using RAC. • The Single Client Access Name (SCAN) should be defined in the DNS or GNS and round-robin between one of 3 addresses, which are on the same subnet as the public and virtual IPs. Prior to 11.2.0.2 it could be defined as a single IP address in the '/etc/hosts' file, which is wrong and will cause the cluster verification to fail, but it allowed you to complete the install without the presence of a DNS.

This does not seem to work for 11.2.0.2 onward. • The virtual machines can be limited to 2Gig of swap, which causes a prerequisite check failure, but doesn't prevent the installation working. If you want to avoid this, define 3+Gig of swap. • This article uses the 64-bit versions of Oracle Linux and Oracle 11g Release 2. • When doing this installation on my server, I split the virtual disks on to different physical disks ('/u02', '/u03', '/u04'). This is not necessary, but makes things run a bit faster. Download Software Download the following software.

On RHEL and its clones you do this with the following type of command as the root user. # rpm -Uvh VirtualBox-4.2-4.2.6_82870_fedora17-1.x86_64.rpm The package name will vary depending on the host distribution you are using. Once complete, VirtualBox is started from the 'Applications >System Tools >Oracle VM VirtualBox' menu option. Virtual Machine Setup Now we must define the two virtual RAC nodes. We can save time by defining one VM, then cloning it when it is installed.
