Configuring Single Instance Applications in CFS/CVM Environments in Continentalclusters, November 2006

START

1.1 Abstract

From version A.06.00, Continentalclusters supports recovering single instance applications and multi-

instance applications over Veritas Cluster Volume Manager (CVM) 4.1 and Veritas Cluster File System

(CFS) 4.1 from Symantec HP Serviceguard Cluster File System products. CVM or CFS 4.1 provides a

cluster shared infrastructure for application and database files.

This whitepaper focuses on the configuration procedures for single instance applications using CVM

or CFS 4.1 in a Continentalclusters environment. To illustrate the recovery of single instance

applications, 10g Oracle Single Instance database is used as an example. The configuration file,

ccrac.config, which was originally intended for Oracle RAC recovery in Continentalclusters, can now

be used to recover single instance applications using CVM or CFS 4.1.

1.2 Audience

This white paper is intended to aid personnel in configuring single instance applications and single

instance databases using CVM or CFS 4.1 for database storage in a Continentalclusters environment

for disaster tolerance. The reader should be familiar with Serviceguard, Continentalclusters,

Metrocluster and HP-UX 11i v2.

1.3 Purpose of Document

The purpose of this document is to outline steps for configuring and recovering single instance

applications over CVM/CFS 4.1 storage in Continentalclusters environment. The document will refer

to a Oracle 10g single instance database as an example for a single instance application.
