The document provides instructions for setting up a two-node Oracle 12c RAC environment within Oracle VirtualBox on a Windows laptop. The main steps include:
1. Configuring VirtualBox with a host-only network and installing Oracle Linux 6 on the first virtual machine.
2. Creating shared virtual disks for the ASM storage and installing Oracle Grid Infrastructure.
3. Cloning the first virtual machine to create the second node, and installing the Oracle 12c database software.
This allows users to test an Oracle 12c RAC sandbox environment locally without requiring additional physical hardware.
