If you’re plan to Install Two node RAC on your virtual machine, Each node want atleast minimum 2GB RAM as per Oracle 11gR2 Installation recommand. So you need atelast minimum 6GB RAM for your laptop. 4 GB for Virtual Machine, remaining for your windows .

The Oracle Cluster Time Synchronization Service (ctssd) can synchronize the times of the RAC nodes. In this case we will reconfigure NTP.

User and Group creation


Directory create

Bash_profile as oracle user.

[root@racnode1 ~]# su - oracle

[oracle@ racnode1 ~]$vi .bash_profile

Do It as same again procedure for other remaining Disks.

ASMLIB Install


Shutdown NODE 1 machine.


[root@racnode1 ~]#shutdown –h now

Manually clone the racnode1.vdi disk using the following commands on the host server.

Create the "racnode2" virtual machine in VirtualBox in the same way as you did for

"racnode1", with the exception of using an existing racnode2.vdi virtual hard drive.

Add two network adapters.


Attach shared disks to racnode2 machine.


Edit .bash_profile for racnode2.

Edit hosts


Ping ipaddress both node

ssh configure
