Step 1: Pre-requisites

Before Start my installation, the below recommanded Memory Configuration needed for you. In this case onle you can smoothly install RAC .

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 .

Step 2: Download Software Download VMware Server and Install

Select 2GB RAM minimum Create new hard disk

(4)

Choose hard disk location

Linux Installation completed successfully. Install Guest Additions

(10)

After installed guest additions successfully, just restart the server. Oracle Installation Prerequisites.

(11)

Edit Hosts (Public ipaddress 192.68.2.102 for racnode2, not 182)

Kernel Parameter /etc/sysctl.conf

(12)

/etc/pam.d/login

cat /etc/selinux/config

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

(13)

Directory create

Bash_profile as oracle user. [root@racnode1 ~]# su - oracle [oracle@ racnode1 ~]$vi .bash_profile

(14)

Shutdown NODE 1 machine.

[root@racnode1 ~]#shutdown –h now

Create three shared Disk

(15)

Do It as same again procedure for other remaining Disks.

(16)

(17)

[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.

(18)

Attach shared disks to racnode2 machine.

(19)

(20)

Edit .bash_profile for racnode2.

(21)

Ping ipaddress both node

ssh configure racnode1

Cluvfy pre –requisites check

11gR2 we would probably use the "runcluvfy.sh" utility in the clusterware root directory to check the prerequisites have been met.
