Sample Configurations with SGeRAC and Oracle RAC 10gR2, March 2009

Introduction

This document discusses the various aspects of architecting, planning, and implementing an Oracle

Real Application Cluster (RAC) 10g Release 2 solution on HP-UX 11i with Serviceguard and

Serviceguard Extension for RAC (SGeRAC). The document also includes a brief description about

planning considerations and presents two sample configurations for Oracle Real Application Cluster

(RAC) 10g Release 2 with Serviceguard, Serviceguard Extension for RAC (SGeRAC), Shared Logical

Volume Manager (SLVM), and Cluster File System (CFS).

This document also provides step by step installation instructions for creating an SGeRAC cluster,

creating shared storage using Shared Logical Volume Manager (SLVM) and CFS, installing Oracle

Clusterware (OC) and RAC, creating a demo database, and creating Serviceguard packages to

synchronize start and stop of the complete solution stack.

Audience

The target audiences are those who are interested in architecting, planning, and implementing

SGeRAC and Oracle RAC 10g clusters.

The reader should be familiar with Serviceguard (SG), Serviceguard Extension for RAC (SGeRAC),

Oracle RAC 10g software, Shared Logical Volume Manager (SLVM), Symantec Veritas Cluster

Volume Manager (CVM), Symantec Veritas Cluster File System (CFS), HP-UX 11i v2, and HP-UX 11i

v3.

Terms and definitions

• APA – Auto Port Aggregation provides bonding of multiple networking interface cards where

traffic is distributed to all interface cards.

• APA/Hot Standby – Auto Port Aggregation Hot Standby mode provides high availability

through bonding of a primary and a standby interface card. Traffic is not distributed.

• CFS – Cluster File System allows multi-system shared access to common file system.

• CSS – Cluster Synchronization Service is a component of Oracle Clusterware that maintains

Oracle cluster membership and heartbeat.

• CSS-HB – Cluster Synchronization Service heartbeat traffic

• CVM – Cluster Volume Manager allows multi-system shared access to volumes.

• GAB – Group Membership Service/Atomic Broadcast manages cluster membership and

cluster communication for Symantec Veritas CFS 4.1/5.0 and CVM 4.1/5.0.

• GMS – Group Membership Service refers to HP’s implementation of the NMAPI2 API on HP-

UX with SGeRAC that provides group membership notification and process monitoring facility

to monitor group status.

• HA – High Availability refers to configurations that are resilient to single failure.

• JBOD – Just a Bunch of Disks refers to single disk or a set of disk in disk enclosures that do not

provide RAID capability for HA.

• LLT – Low Latency Transport provides kernel-to-kernel communications at link level and

monitors network connections for Symantec Veritas CFS 4.1/5.0 and CVM 4.1/5.0.

Distributes Symantec Veritas traffic amount network connections and maintains Symantec

Veritas heartbeat.

• MNP – Multi-node package, a Serviceguard package that runs on multiple nodes at the same

time and can be independently started and halted on individual nodes.

• NIC – Network Interface Card, host bus adapter for network communications, for example

Ethernet card.

• OC – Oracle Clusterware can run in conjunction with Serviceguard Extension for RAC and

provides Oracle cluster membership and resource management services.
