1. Install Oracle VirtualBox and configure host-only networking
2. Create one Oracle Linux 6 virtual machine and install the OS
3. Configure shared storage by creating ASM disks
4. Clone the first node to create a second identical virtual machine
5. Install Oracle Grid Infrastructure and configure the RAC environment
6. Install the Oracle database software and create a database that is accessible from both nodes.
