If the organization decides to deploy the RAC solution, it should fulfil the hardware
requirements and follow configuration and management best practices to ensure that the
RAC provides all the potential advantages.
5.
Many companies have carried out successful migration of their mission-critical databases
from big SMP Unix machines to multi-node Oracle RAC clusters based on lower-cost
industry-standard commodity X86-64 servers running Linux. In the last decade, these
servers have advanced significantly in terms of reliability as well as processing power.
Practical experience has shown that the new architecture can provide a highly available
and scalable infrastructure for enterprise-level applications.
Summary
In this chaper, you received an overview of the architecture and components of Oracle RAC. I explained how Oracle
RAC provides high availability and scalability database solutions. I also demonstrated how to use Oracle RAC to build
a Grid computing infrasturecture to consolidate many database services. In conclusion, I reviewed what factors IT
departments should consider to justify an Oracle RAC deployment.
In this introductory chapter, it is worthwhile listing some invaluable MOS notes that introduce some very useful
tools and utilties for Oracle RAC. The tools and best practices mentioned in these MOS notes can be very beneficial
for the study of Oracle RAC technology.
RACcheck—A RAC Configuration Audit Tool (MOS doc ID 1268927.1)
is about a RACcheck tool that can be
used to audit various important configuration settings for Oracle RAC, Clusterware, ASM, and the Grid Infrastructure
environment.
RAC and Oracle Clusterware Best Practices and Starter Kit (Platform Independent) (MOS doc ID 810394.1).
This document provides generic and platform-independent best practices for implementing, upgrading, and
maintaining an Oracle RAC system. It also lists links to platform-specific documents.
ODAchk—- Oracle Database ApplianceODA Configuration Audit Tool (MOS doc ID 1485630.1).
This
document introduces the ODAchk tool, which automates the assessment of ODA systems for known configuration
problems and best practices.
TFA Collector—The Preferred Tool for Automatic or ADHOC Diagnostic Gathering Across All Cluster Nodes
(MOS doc ID 1513912.1). This document introduces a new tool called TFA Collector (aka TFA) a diagnostic collection
utility for Oracle Clusterware/Grid Infrastructure and RAC systems.
