Oracle 10g RAC On Windows 2003 Using VMware Server
This article describes the installation of Oracle 10g release 2 (10.2.0.1) RAC on Windows 2003 Server Standard 
Edition using VMware Server with no additional shared disk devices. 
● Introduction 
● Download Software 
● VMware Server Installation 
● Virtual Machine Setup 
● Guest Operating System Installation 
● Oracle Installation Prerequisites 
● Install VMware Client Tools 
● Create Shared Disks 
● Clone the Virtual Machine 
● Install the Clusterware Software 
● Install the Database Software and Create an ASM Instance 
● Create a Database using the DBCA 
● TNS Configuration 
● Check the Status of the RAC 
Introduction
One of the biggest obstacles preventing people from setting up test RAC environments is the requirement for shared storage. In a production environment, shared storage is often 
provided by a SAN or high-end NAS device, but both of these options are very expensive when all you want to do is get some experience installing and using RAC. A cheaper 
alternative is to use a FireWire disk enclosure to allow two machines to access the same disk(s), but that still costs money and requires two servers. A third option is to use 
VMware Server to fake the shared storage.

ORACLE-BASE - Oracle 10g RAC On Windows 2003 Using VMware Server

Using VMware Server you can run multiple Virtual Machines (VMs) on a single server, allowing you to run both RAC nodes on a single machine. In additon, it allows you to set up

shared virtual disks, overcoming the obstacle of expensive shared storage.

Before you launch into this installation, here are a few things to consider.

● The finished system includes the host operating system, two guest operating systems, two sets of Oracle Clusterware, two ASM instances and two Database instances all

on a single server. As you can imagine, this requires a significant amount of disk space, CPU and memory. To complete this installation I used a dual 3.0G Xeon server

with 4G of memory.

● This procedure provides a bare bones installation to get the RAC working. There is no redundancy in the Clusterware installation or the ASM installation. To add this,

simply create double the amount of shared disks and select the "Normal" redundancy option when it is offered. Of course, this will take more disk space.

● During the virtual disk creation, I always choose not to preallocate the disk space. This makes virtual disk access slower during the installation, but saves on wasted disk

space.

● This is not, and should not be considered, a production-ready system. It's simply to allow you to get used to installing and using RAC.

Download Software

Download the following software.

● VMware Server

● Oracle 10g (10.2.0.1) CRS and DB software

VMware Server Installation

For this article, I used CentOS 4.3 as the host operating systems. To use Windows as the host operating system, simply run the executable installation file and ignore the following

VMware Server installation information.

First, install the VMware Server software. On Linux you do this with the following command as the root user.

# rpm -Uvh VMware-server-*.rpm

Preparing... ########################################### [100%]

1:VMware-server ########################################### [100%]

Then finish the configuration by running the vmware-config.pl script as the root user. Most of the questions can be answered with the default response by pressing the return key.

The output below shows my responses to the questions.

# vmware-config.pl

Making sure services for VMware Server are stopped.
