OCR, Vote disk, clusterware
Purpose
In Oracle Clusterware 10g and 11g, there are two important cluster files, the Oracle Cluster Repository
(OCR) and the Voting Disk. Due to the nature of these files, they must be placed on shared devices; either
on cluster filesystems, NFS or shared raw devices.
The aim of this document is to provide a clear and concise method to create the OCR and voting disk on
raw devices using native OS utilities; i.e, without the need of extra licensable cluster software tools. The
intent of the document is to augment the platform specific documentation for Clusterware.
This document will focus on Oracle Clusterware 10g and 11g Release 1. From Oracle Clusterware 11gR2,
OUI no longer supports installation of Oracle Clusterware files on block or raw devices. Install Oracle
Clusterware files either on Oracle Automatic Storage Management disk groups, or in a supported shared file system.
Please refer to Oracle® Grid Infrastructure Installation Guide 11g Release 2 (11.2) for different platform,
especially chapter 1.3.6 Prepare Storage for Oracle Automatic Storage Management for details.
Scope
The procedures will be presented for the following operating systems:
o Linux
o AIX
o HP-UX
o Solaris
o Tru64
