real-application-cluster-installation-step-by-step-guide-on-linux-using-vmware-server/ 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 http://downloads.vmware.com/d/info/datacenter_downloads/vmware_server/2_0?hl=en&rlz=&q=vmware%20server%20download&aq=f&aqi=g10&aql=&oq= Download Oracle Enterprise Linux 32 Bit https://edelivery.oracle.com/linux Download Oracle Software Grid Infrastructure and Database Software http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-linuxsoft-085393.html

Step 3: Install Oracle Enterprise Linux on Virtual Box 4.1.4 Open Virtual Box.

Select 2GB RAM minimum Create new hard disk

Kernel Parameter /etc/sysctl.conf

/etc/security/limits.conf

/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.

User and Group creation

Directory create

Bash_profile as oracle user.

[root@racnode1 ~]# su - oracle

[oracle@ racnode1 ~]$vi .bash_profile

RPM Packages

Shutdown NODE 1 machine. [root@racnode1 ~]#shutdown –h now

Create three shared Disk

Now Restart the NODE 1 racnode1 machine and after restarted, partition your disks like below

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

racnode1

racnode2

racnode1

racnode2

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.

Grid Infrastructure installation

Execute both root scripts on both node one by one.

Do it as same like racnode2 also.

Grid Infrastructure installation completed successfully.

Database Software Install

Check whether the created database on both node working properly or not.
