RAC and Oracle Clusterware Best Practices and Starter Kit (Platform Independent) (Doc ID 810394.1)

Last updated on OCTOBER 18, 2023

Applies to:

Oracle Database - Standard Edition - Version and later
Oracle Unified Directory - Version to [Release 11g]
Oracle Database - Enterprise Edition - Version and later
Gen 1 Exadata Cloud at Customer (Oracle Exadata Database Cloud Machine) - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Information in this document applies to any platform.


The goal of the Oracle Real Application Clusters (RAC) series of Best Practice and Starter Kit notes is to provide customers with quick knowledge transfer of generic and platform specific best practices for implementing, upgrading and maintaining an Oracle RAC system. This document is compiled and maintained based on Oracle's experience with its global RAC customer base.

This Starter Kit is not meant to replace or supplant the Oracle Documentation set, but rather, it is meant as a supplement to the same. It is imperative that the Oracle Documentation be read, understood, and referenced to provide answers to any questions that may not be clearly addressed by this Starter Kit. 

All recommendations should be carefully reviewed by your own operations group and should only be implemented if the potential gain as measured against the associated risk warrants implementation. Risk assessments can only be made with a detailed knowledge of the system, application, and business environment.

As every customer environment is unique, the success of any Oracle Database implementation, including implementations of Oracle RAC, is predicated on a successful test environment. It is thus imperative that any recommendations from this Starter Kit are thoroughly tested and validated using a testing environment that is a replica of the target production environment before being implemented in the production environment to ensure that there is no negative impact associated with the recommendations that are made.


This article applies to all new and existing RAC implementations as well as RAC upgrades.
