In this article we will be installing 2 node 11gR2 RAC on Oracle Linux 6.5. We will be looking at below steps
Configure VM for Node 1
Open virtual box and create a new VM for node 1. We will be installing OEL 6.5 on both RAC nodes.
Create New VM
Open virtual box and click on New. Create first virtual machine with oraracn1 as the name

Min RAM allocation should be 4 GB per RAC node

Create a virtual disk now

Select VDI and click next

Select Dynamically allocated option and click next

Allocate Min 80 GB HDD to your virtual machine. You can allocate even more if you have good hard disk space. Click on Create

Now your virtual machine should be created. This is how your virtual box will look like
Right click on virtual machine and select settings. Under System settings, make sure to set below bootorder

Under storage > Optical Drive > choose OEL 6.5 iso file from your system.

Under Network, make sure attached to is set to Bridged Adapter and Enable the Network Adapter

In RAC, we need to have two network adapters. So, enable the second adapter same like the first one.

Click on OK to complete the RAC node 1 setup.
