The authors, Ben Prusinski and Syed Jaffer Hussain , have successfully managed to write an excellent book about RAC 11gR1 and RAC 11gR2, something not really easy to accomplish, and they have clearly demonstrated the differences between both releases.
From the concept to the syntax, this book covers what is needed to successfully build a RAC environment. It focuses on concepts, installation, administration, backup and recovery, streams and data guard. If you want to build a highly available environment, this book is for you.
The two first chapters clearly focus on the high availability concepts and architecture of a RAC environment. Many DBAs jump directly to the syntax and forget about the concepts and the architecture. Those DBA will face serious problems with each new release of Oracle RAC. I highly recommend to read those 2 first chapters before jumping to the others. If you are a single instance DBA who never managed to install Oracle clusters, these two first chapters are also for you; read them and learn how to design the key components like networks and storage.
Chapters 3 and 4 discuss Oracle Clusterware installation including grid infrastructure and ASM. They help you build the first components of your clusterware.
Chapter 5 is about managing and troubleshooting Oracle 11g . After installing the grid infrastructure you will be faced with many background processes. This chapter teaches you the commands to successfully administer your clusterware components as well as troubleshooting any cluster issue.
Chapter 6 is about installing the RAC database with many tips and best practices to follow.
Chapter 7 deals with back up and recovery of RAC databases. One of the most important task for a HA DBA. Tips and suggestions have been provided in this chapter.
After building the RAC environment, every DBA should care about the database performance; chapter 8 covers the most important components to focus on in your day to day monitoring.
Chapter 9 covers the upgrade of Oracle 10g R2 Clusterware to Oracle 11g R1 and how to Upgrade to Oracle 11g R2 Clusterware. This is a really important task for any HA DBA.
The chapter 10, in my opinion, one of the best chapters of this book, is about real-world examples; the authors shared their extensive experience of practical scenarios and examples.
The book ends with a great appendix containing a vast amount of Oracle RAC commands and tips.
In summary, the authors have produced a work of great quality and value. I recommend this book to all DBAs working on RAC systems for the following reasons:
- Clear explanation of RAC concepts and architecture.
- Clear step by step installation of clusterware and RAC databases.
- Real-world examples and tips.
- Troubleshooting guide for most common performance issues in RAC.
- Good summary of the most important RAC commands.
