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 hostonly 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.

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.

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.

[root@vmmgr stage]# 4.3 Login into Oracle VM Manager 3.0.3 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.
