Q&A

Running today’s non-critical business applications in virtualized environments has shown to be efficient and cost saving. Oracle VM is the only software based virtualization solution that is fully supported and certified for Oracle Real Application Clusters.

Background

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 Support will assist customers running Oracle products on VMware in the following manner: Oracle will only provide support for issues that either are known to occur on the native OS, or can be demonstrated not to be as a result of running on VMware.

What is Oracle RAC

Oracle RAC Architecture

• Allows a Shared Database to run on 2 or more nodes • Requires – Shared Disk for Database Files – Public and Private Networks – Common OS version across nodes

7

What is Virtualization

8

9

Virtualization is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system (OS), storage device, or network resources

11

What is Oracle VM

12

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

virtual machines. dom0 - domain 0

A self-contained virtualization environment

designed to provide a lightweight,

secure, server-based platform for running

virtual machines.

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. Manages resources, including ISO files,

virtual machine templates and sharable hard disks.

deploy operating systems and application

software within a supported

virtualization environment.

Oracle VM Architecture

Bare-Metal Server

Is a component that translates the

virtual machine into the underlying hardware. Two Types : Type1 &

Type2

13

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.

Why run Oracle RAC

on Oracle VM?

15

Server Consolidation

Oracle RAC databases with underutilized CPU resources or variable CPU utilization can often benefit from consolidation with other workloads using server virtualization.

Sub-capacity licensing Oracle licensing model requires the Oracle RAC 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 allow customers to only license those CPUs used by the partition instead of licensing all CPUs on the physical server.

16

Create a virtual cluster

Oracle VM enables the creation of a virtual cluster on a single physical server. This use case is particularly interesting for product demos, educational settings, and test environments.

Rapid Provisioning

Oracle VM can help reduce the deployment time. Oracle VM supports the ability to create deployment templates. These templates can then be used to rapidly provision new (Oracle RAC) systems.

Template Documentation

21

RAC OVM Templates - Features

• Builds production ready Oracle RAC (Cluster) in about 30 minutes – 11.1: 2-node, then manual add node – 11.2: N-node initial build, automated add/remove nodes • 11.2 Templates allow

– Standard 2-node build (Interview based) – Automatic network setup directly from Dom0 – N-node build, also directly from Dom0 – Run as root, oracle/grid users – Automatic add/remove any number of nodes or instances – Options to modify environment after a build (Create DB, add DBConsole) – Works well & tested with Oracle Linux 6 (official RAC/OL6 certification pending)

22

Using The Template

• Step 1 Download Template 32/64 11.1/11.2.0.1/11.2.0.2/11.2.0.3 • Step 2 Register Template with Oracle VM Manager • Step 3 Create 2+ VMs • For Non Production

– Step 4 Create Shared Disk using OVM Manager • Assigned Shared disk to all Guest VMs using OVM Manager

• For Production Deployment

– Step 4 Identify Physical Shared Disk • Update all Guest VM’s vm.cfg files with location of shared disk • OVM3 can help automate this part via Manager

• Step 5 Boot all VMs • Step 6 Run One Command to Configure and Build RAC database

23

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

24

Oracle RAC on Oracle VM

Production Deployment

Bare-Metal Server: A bare metal environment is a computer system in which a virtual machine is installed directly on hardware rather than within the host operating system (OS).

Dom0 : The first domain started on boot is called the Dom0 or Domain zero. Dom0 is used to start new domains and also to access the hardware directly.

A virtual machine (VM) is a "completely isolated guest operating system installation within a normal host operating system".

Hypervisor is virtual machine manager (VMM), is one of many hardware virtualization techniques allowing multiple operating systems, termed guests, to run concurrently on a host computer.
