Background

Running today’s non-critical business applications invirtualized environments has shown to be efficientand cost saving.

Oracle VM is the only software based virtualization solution that is fully supported andcertified for Oracle products.

Support Position for Oracle Products Running on VMware Virtualized Environments [ID 249212.1]Oracle has not certified any of its products on VMware virtualized environments. Oracle Supportwill assist customers running Oracle products on VMware in the following manner: Oracle will onlyprovide support for issues that either are known to occur on the native OS, or can bedemonstrated not to be as a result of running on VMware.

What is Virtualization?

6

What is Virtualization?It is a abstraction of computer hardware resources

Virtualization technology emulates real — or physical — computing

resources, such as desktop computers and servers, processors

and memory, storage systems, networking, and individual

applications.

A hypervisor — also known as a virtual machine manager

(VMM) — allows multiple “guest” operating systems

to run concurrently on a single physical host

computer.

100 Sun Fire V880 systems runningOracle Solaris 8

17 Sun SPARC Enterprise T5240s systemsrunning Oracle Solaris 10

✓ Aggregate throughput performance would not change significantly for more workloads. In most cases, a singleT5240 can replace six V880s.✓ Reduced space: 100 V880s require 50 data center racks, whereas 17 T5240s can fit in a single rack.✓ Approximately 660,000 BTUs of heat generation would be removed from the data center.✓ Approximately $200,000 would be saved in electricity costs per year (ignoring the cost of cooling).✓ Acquisition costs for the new systems would be completely offset by the OPEX savings achieved in the first year.

What is Oracle VM ?

13

Oracle VM – Foundation for Cloud

• At the core of Oracle’s Cloud strategy

• Integrated VM lifecycle & cloud

management solution with Oracle

Enterprise Manager

• Supports both x86 and SPARC

• Certified for Oracle products

• Cloud platform for Oracle & Non-Oracle

applications

oSupports Oracle Linux, Oracle Solaris, Microsoft

Windows, and other Linux distributions

14 Bare-Metal Server

Is a component that translates the

virtual machine into the underlying

hardware.

Installed with Oracle VM Server. It communicates with Oracle VM Manager for management of

virtual machines. dom0 - domain 0

Manages virtual machine lifecycle, including creating virtual machines from installation media or from a virtual machine template, deleting, powering off, uploading, deployment and live migration of virtual machines.

A self-contained virtualization environment

designed to provide a lightweight,

secure, server-based platform for running

virtual machines.

deploy operating systems and application

software within a supported

virtualization environment.

Oracle VM

15

Oracle VM Family: Choice and FlexibilityFrom Fully Configurable Software to “Turn Key” Systems

Oracle VM software for x86 & SPARC

• Zero cost license: pay only for support

• Full functionality including all management software

• Your hardware infrastructure

Virtual Compute Appliance

• Enterprise class, turn key converged infrastructure system containing servers, storage,

network, and software

• From power-on to production in about an hour

• Automated installation and configuration

16

Oracle VM for x86 Architecture Live migration, high availability, template deployment, dynamic resource scheduling

Oracle VM Manager• Centralized management server•Web browser-based: No client required•Manage hundreds or thousands of VMs centrally•Advanced virtualization management included

Oracle VM Server • Installs on “bare-metal” servers in about a minute• High performance at scale: Up to 240 physical CPUs and 6TB memory; Up to 128 vCPU and 2TB memory per VM

17

Oracle VM Server Features

High Availability: You can configure resources to restart the guests on another host if the underlying host fails.

Live Migration: You can relocate the guests from one host to another with no loss of service.

Load Balancing: If configured, Oracle VM automatically load balances upon guests startup

Performance: Xen hypervisor is among the fastest forms of virtualization.

Rapid Provisioning: Through the use of cloning and virtual machine templates, Oracle VM can quickly and efficiently create new guest operating system.

VM Templates: Oracle provides wide-range of preconfigured virtual machine templates.

Some of the benefits of Oracle VM

Sub-capacity licensingOracle licensing model requires the Oracle database to be licensed for all CPUs on each server in the cluster.Oracle VM can be configured in such way that it is recognized as a hard partition. Hard partitions allowcustomers to only license those CPUs used by the partition instead of licensing all CPUs on the physicalserver.

Distributed Resource Scheduling (DRS)• Optimizes virtual machine CPU resource utilization in a server pool.

– Automatically moves virtual machines to another OVM Server within the pool if the threshold exceeds the existing server pool policy.– Thresholds can be set for both CPU and Network

Distributed Power Management (DPM)• Used to increase the consolidation ratio of VMs into least amount of OVM Servers required.

– Goal is to keep only minimum number of necessary OVM Servers running.– If policy finds OVM Servers without VMs, it can shutdown OVM Servers to conserve power.

Oracle VM Templates for Oracle Database

27

Oracle VM Templates for Oracle Databasehttp://www.oracle.com/technetwork/server-storage/vm/database-templates-12c-11gr2-1972804.html

28

RAC OVM Templates - Delivery Mechanism

• 32 bit and 64bit versions• Image files are built with ‘sparse file’ support• Inside each zip are tgz archives with the following files:

– VM Config file (text file)– Opatch lsinventory sample output– README / PDFs for installing– Disk 1 image file: Operating System– Disk 2 image file: Oracle Software

• Includes Clusterware, ASM and RAC• Follow the instructions in provided PDF files or document for the new DeployCluster tool

29

Using The RAC OVM TemplatesSteps to execute RAC OVM templates

• Step 1 Download Template 32/64• 11.1/11.2.0.1/11.2.0.2/11.2.0.3/Oracle RAC 12c Release 1 (12.1.0.1.0)

• Step 2 Register Template with Oracle VM Manager• Step 3 Create 2+ VMs• Step 4 Shared Storage

• For Non Production: Create Shared Disk using OVM Manager• Assigned Shared disk to all Guest VMs using OVM Manager

• For Production Deployment: Identify Physical Shared Disk• OVM2: Update all Guest VM’s vm.cfg files with location of shared disk• OVM3: Attach physical disks using Oracle VM Manager

• Step 5 Boot all VMs or use Deploycluster tool and skip Step 6• Step 6 Run OneCommand to Configure and Build RAC database

30

RAC on OVM – Deployment Configuration

• Two types of deployments• Production Oracle RAC OVM Configurations [Supported]

• Each RAC node must be deployed on a separate physical server for production environments• Shared database disks must be on physical disks

• Test Oracle RAC OVM Configurations• Above requirements are relaxed

• Templates support both configurations, each has its own PDF to help with steps

Download deploycluster toolhttp://www.oracle.com/technetwork/server-storage/vm/rac-template-11grel2-166623.html

Then unzip it anywhere you wish, e.g.$ cd $HOME$ unzip -q RACOVM-Deploycluster-tool.zip$ cd deployclusterSome of the useful files to notice are:deploycluster.py - Deploycluster tool – RUN THISdeploycluster.ini - Options for deploycluster tool itselfREADME.txt - Details explanation of all flags/optionsutils - Directory with useful files, e.g:

netconfig*.ini - Sample netconfig.ini filesnetconfig.zip - Updated netconfig (may be needed when deploying older templates)params-sample.ini - Sample params.iniREADME.txt - Backwards compatibility steps for Oracle VM2 users

33

Create a netconfig.ini file

Using a simple text editor copy the sample netconfig.ini file from the utils directory, then adjust the namesand IPs suitable for your environment.

34

Running deploycluster.py$ ./deploycluster.py -u admin -p MyP123 -M racnode.0,racnode.1
