Oracle Real Application Cluster 11g Release 2 Templates for Oracle VM (Test Configuration)

2 of 34

Overview:

This document introduces the Oracle Real Application Clusters 11g Release 2 (11.2.0.3) Oracle VM

Templates. It explains the concepts of the templates and how to use the templates to build Oracle RAC

clusters. Two separate templates are provided base on:

• Oracle Linux 6 U2 32bit Linux or Oracle Linux 6 U2 64bit Linux

For the latest version of this document and more information on the benefits of Oracle RAC, Oracle VM

and Templates, see OTN at: http://www.oracle.com/technetwork/server-storage/vm/rac-template-11grel2-

166623.html and Note# 1185244.1 on My Oracle Support.

NOTE: Oracle VM 3 users should use the new deploycluster tool on the above URL on OTN.

Supported vs. Unsupported implementations:

There are 2 separate scenarios for implementation of an Oracle RAC template

• Production – Supported: where the shared disk is configured as physical devices (‘phy’) passed

through to the guest Oracle VMs. For more details on running Oracle RAC in Oracle VM

environment, see: http://www.oracle.com/technetwork/database/clustering/oracle-rac-in-oracle-vm-

environment-131948.pdf

• Test – Unsupported: where the shared disk is configured as virtual devices (‘file’) – in this

configuration both guests can also run on one Oracle VM server.

This document covers the Test (Unsupported) configuration. In test environments you may:

a) Run both machines on the same Oracle VM Server (DOM-0)

b) Use files in DOM-0 to emulate shared disks for the Oracle RAC Node Dom-U

Both are not allowed in Production environments; however they can be used as a sandbox / demo

environment for functional testing using Oracle RAC.

Naming Convention:

This document describes both x86 (32bit) and x86-64 (64bit) environments. Template file & directory

names are as follows:

32 bit: OVM_OL6U2_X86_11203RAC_PVM

64 bit: OVM_OL6U2_X86_64_11203RAC_PVM

Screenshots refer to templates as: OVM_EL5U4_X86_11GR2RAC_PVM, these are generic screenshots,

substitute your version number, i.e. 11201, 11202 or 11203 based on release used.

Feedback:

Feel free to post feedback at the Oracle VM or Oracle RAC Forums on the Oracle Technology Network:

Oracle VM: http://forums.oracle.com/forums/forum.jspa?forumID=823

Oracle RAC: http://forums.oracle.com/forums/forum.jspa?forumID=62

Or contact Oracle Support.

NOTE: The Oracle RAC build scripts inside the template (under /u01/racovm directory) are only supported

inside the Oracle VM RAC Templates. Do not modify or run them in other environments.
