Executive summary
This white paper provides guidance and best practices for performing backup and restore of Oracle
10g Real Application Clusters using HP Data Protector Software.
Since the release of Oracle 9i Real Application Clusters, there has always been uncertainty about
what needs to be backed up and how to backup the RAC database. We will try to address these
questions throughout this paper.
This paper is not:
• Intended to replace the HP Software Data Protector installation and integration guides with Oracle
• A performance whitepaper on backup and recovery of Oracle Real Application Clusters
• A step-by-step installation and configuration guide
Overview
HP Data Protector Software Oracle integration enables customers to perform online and offline
backups of an Oracle database by using the Oracle Recovery Manager and acting as a Media
Management Layer. In the past, the integration with an Oracle Real Application Cluster environment
was performed using just one of the instances of the cluster.
On the other side, Oracle's Workload Management in a Cluster environment managed the workload
distribution, providing optimal performance. With Oracle 10g, the concept of Services was
introduced. It enables to group database workloads and distribute them over specific instances.
Integrating HP Software Data Protector with Oracle 10g Real Application Clusters, helps you benefit
from using the workload management functionality by distributing the backup and restore load over
more than one instance in the cluster.
Target audience
The target audience for this whitepaper are customers, system integrators and solution architects.
Basic knowledge of Data Protector and Oracle 10g RAC is advisable to understand this white paper
fully.
Review of test configuration
The following hardware configuration was used for the testing:
• 5 HP Integrity Server rx2620 running HP-UX 11.23
• 1 HP StorageWorks EVA5000
• 1 SAN Tape Library MSL5000 with 2 SDLT320 drives
• 2x 1000 Base-T per server
The following software configuration was used for the testing:
• HP Data Protector 6.0 Cell Manager running on HP-UX
• Oracle 10g RAC version 10.2.0.3 running on 4 nodes using Oracle clusterware
• Oracle 10g version 10.2.0.3 for the Oracle Recovery Catalog (RCVCAT)
The Oracle10g RAC database (RAC) was configured using 2 ASM disk groups:
• Disk Group DG_DB (database): 4 EVA LUN (Vdisk), each with 100 GB
• Disk Group DG_FRA (Flash Recovery Area): 4 EVA LUN (Vdisk), each with 25 GB
