Oracle Virtualization – Installing Oracle VM Server 3.0.3,

Oracle VM Manager 3.0.3 and Deploying Oracle RAC 11gR2

(11.2.0.3) Oracle VM templates Linux x86 64 bit for test

configuration

In two posts I will cover Oracle VM server 3.0.3 and 3.1.1 technology; the

first (this one) will be dedicated to 3.0.3 and the second (next one)to

3.1.1. Oracle provides virtualization software ranging from bare metal

implementations based on Oracle VM Server to a Microsoft Windows/Linux/Mac OS

and Solaris deployments based on Oracle Virtual Box. Oracle VM Manager

facilitates management of Oracle VM Server. In this article you will look at

the installation of Oracle VM server 3.0.3 and Oracle VM Manager 3.0.3 on

Oracle VirtualBox and in addition I will provide guidelines for deploying

Oracle RAC 11gR2 (11.2.0.3) Oracle VM templates Linux x86 64 bit for test

configuration using Oracle VM Manager. For information relating to earlier

Oracle VM server 2.2.1 deployment with RAC templates click here. All software

can be downloaded from edelivery.oracle.com (Oracle Software Delivery Cloud)

and the templates (version 11.2.0.3) can be downloaded as a patch from MOS

(patch 12694014). The approach described in the article is applicable on any

supported platform although I am using Oracle VirtualBox for testing. Bear in

mind that contrary to Oracle VM server 2.2.1 in Oracle VM Server 3.0.3 YOU

WILL NOT BE ABLE to have RAC templates deployed in Virtual box environment

due to Oracle VM 3.0.3 dmidecode requirement that VirtualBox does not comply.

I will show briefly guidelines for a successful RAC template deployment after

Oracle VM Server 3.0.3 and Oracle VM Manager are installed. In the next post

I will present a detail steps by step guide for RAC templates deployment

using Oracle VM server 3.1.1 and Oracle VM Manager 3.1.1.

Software versions used are:

Oracle VirtualBox 4.1.16

Oracle VM Server 3.0.3

Oracle VM Manager 3.0.3

OEL 6.2

The article will cover the following:

VirtualBox configuration for VM Server machine and VMManager

machine

Installation of Oracle VM Server

Installation of Oracle VM Manager

Deployment of Oracle RAC 11gR2 Oracle VM templates Linux x86

64bit for test configuration

In real life Oracle VM server runs on a dedicated set of servers and is

installed as a bare metal product without the need of an Operating system.

Oracle VM Manager is installed on a Linux box. Oracle VirtualBox can be

successfully used for testing and self-study of the new features.

The main components in the architecture are two virtual machines.

Virtual Machine IP Address OS Purpose

OracleVMServer303 192.168.2.21 OEL XEN with Oracle

VM Server 3.0.3

Oracle VM Server

3.0.3

OracleVMManager303 192.168.2.31 OEL 6.2 Oracle VM Manager

3.0.3

1. VirtualBox configuration to run Vmserver303 machine and VMManager303 machine.

The article assumes that the VirtualBox is downloaded and installed and

that both virtual machines are configured as follows.

VM for Oracle VM Server 3.0.3

VM for Oracle VM Manager 3.0.3

OEL 6.2 is installed as a base OS for the OracleVMManager303 while Oracle VM

Server is used for the OracleVM303 machine. Note that in case of

OracleVMManager303 machine Guest additions are installed and the shared

folder feature is enabled by placing in the guest /etc/rc.local the following

command’ mount -t vboxsf OracleVMServer /media/windows’. Both machines also

have multiple NIC defined. Bridged interfaces are required for the OracleVM

and OracleVMManager setup. NAP is for access to the Internet and the host-

only adapters are for access from the host OS (Microsoft Windows in my case).

All iso images are in the shared folder and the OEL or Oracle VM server iso

is specified for the initial OEL and Oracle VM Server installation. For

additional information related to OEL 5.X installation click here.

2. Installing OEL 6.2 in OracleVMManager303 virtual machine

OEL 6.2 will be used to host the Oracle VM Manager 3.0.3. Install OEL

6.2 as shown below. Insert the bootable ISO and start the OracleVMManager303

virtual machine. Skip the media test.

Press Next.

Select Language.

Select keyboard.

Select storage device type.

Acknowledge.

Name the computer.

Specify IP addresses for each interface.

Get back to the network configuration screen and press Next to continue.

Configure geographic location

Enter root password.

Select an installation type.

Select Next to continue.

Select Next to continue.

Select Basic server.

Press Reboot.

Press Forward.

Acknowledge and press Forward.

Press Forward.

Enter user credentials and ress Forward.

Select NTP

Press Finish.

Select a user.

Run installation of the latest guest additions (GE). Here the screenshot is for illustrative

purpose only and uses older GE. Wait for the installation to complete and reboot at the end.

Modify /etc/hosts as show below. You are ready to install Oracle VM Manager 3.0.3 or

later.

Reboot the VM.

3. Installing Oracle VM Server 3.0.3 in OracleVMServer303 virtual machine

Start the OracleVMServer303 virtual machine.

Press Next after identifying the location of the ISO image of the VM

Server 3.0.3.

Locate the VM Server iso image for initial installation.

Verify and start the installation.

Press Enter.

Press Skip.

Select keyboard.

Accept license agreement.

Acknowledge.

Select the options for a fresh install (remove all partitions and

create default layout).

Press Yes.

Press Yes.

Press Ok.

Press OK.

Select a network interface and press OK.

Enter IP address and netmask.

Enter gateway and DNS.

Enter hostname

Enter time zone.

Enter a password.

Press OK.

Wait for the installation to complete and press Reboot.

Press Oracle VM Server-ovs.

Examine the screen and press Alt-F2 to login.

Now you can login.

4. Install and configure Oracle VM Manager 3.0.3

You can access Oracle VM 3.0.3 and Oracle VM Manager 3.0.3

documentation from here. Detail information related to the

prerequisites and installation of Oracle VM Manager 3.0.3 is available

here.

4.1 Ensure that prerequisites for Oracle VM Manager are met

Transfer the image VMManager303.iso into the OEL 6.2. Loop mount the

ISO.

mkdir -p /u02/stage

mount -o loop /u02/VMManager303.iso /u02/stage

Make sure that prerequisites for installation are met. Run Oracle

supplied ./createOracle.sh in order to configure the environment for

Oracle VM Manager 3.0.3 installation.

5. Guidelines for Installing two nodes RAC using VM templates

Oracle VM Server 3.0.3 relies on dmidecode for some hardware detection

capabilities and this is not exposed to VirtualBox guests. Thus,

discovery from VM Manager fails. VM Server 3.1.1 is supposed to drop

the dmidecode requirement(See my next post with Oracle VM Server 3.1.1

and Oracle VM Manager 3.1.1).

The templates installation is described in great details for Oracle VM

server 2.1. Although conceptually nothing has changed there a couple of

turning points that needs to be carefully observed.

I successfully got RAC templates running on a bare metal installation

and the major stumble blocks are summarized below.

5.1 Follow carefully the Getting Started Guide for Release 3.0.3

5.2 Upload the template by using ftp

5.2.1 Enable ftp

5.2.2 Place the template files in the home directory for the user. For

example /home/gjilevski

5.2.3 Define FTP URL as follows

ftp://gjilevski:password@192.168.2.31/OVM_OL5U7_X86_64_11203RAC_PVM-

2of2.tgz

ftp://gjilevski:password@192.168.2.31/OVM_OL5U7_X86_64_11203RAC_PVM-

1of2.tgz

Where the *.tgz are in /home/gjilevski

5.3 Create shared files ASM1,ASM2,ASM3,ASM4,ASM4 each of 2GB for RAC

template deployment

5.4 Follow the template deployment documentation having in mind menus

has changed.

6. Conclusion

You looked at how to Install Oracle VM Server 3.0.3 and Oracle VM Manager

3.0.3. Guidelines were provided for installing Oracle RAC 11.2 from templates

for VM. In the next post you will have a look at how to perform an upgrade to

Oracle VM 3.1.1 and Oracle VM Manager 3.1.1 and step by step guide for Oracle

RAC deployment using templates on Oracle VM 3.1.1 technology.
