Great Book

This book is really good, provides a complete coverage on RAC. The author has an excellent grasp of the subject and explains every detail in an easy to understand manner. This is the best book I have found on the subject.I am enjoying every bit of detail, and these scripts and explanations are saving us through our implementation.

Good Book

This is an excellent book, covers RAC north south east and west. Internals are covered in great detail. I have not found any other book that has such details. The real good thing about this book is that the author provides examples with dumps and explains them so you understand and don't have to take the author for granted. You can see and understand from the examples.TAF is covered in great detail. From the mechanics to using them inside Java code for complete transparent failover is covered with examples.I also liked the performance tuning chapters, the author has taken all angles into consideration while writing these 3 chapters. By providing extensive descriptions and a several scripts the author has impressed me. We at our company have used several of his scripts and found helpful.The support chapters are excellent.

Outstanding Book on RAC

This is a complete reference that provides 100% business value to professionals using or moving to RAC. We have already used many of his scripts over the last two weeks in our test environment and has helped us move forward considerably. His internals chapter is excellent. Good work Murali. I highly recommend this book

Excellent Book!

This book has depth; the contents are full of meat. In these pages is something for everyone. Murali discusses RAC starting with the single instance and covers clustering, it covers internals to a great detail. Installation and Performance tuning chapters are no exception. Author focus has been Oracle while touching on Linux and Windows installation. The book presents the topic in a clear and concise fashion.

Excellent book covering the Internals of RAC

The book covers a great detail of Oracle technology. Having worked with RAC since its first release. I think the author has taken great efforts to start with the basic concepts and drive from the basic Oracle concepts into the clustering technology to make it a complete comprehensive book. I wish I had this book when I first started into RAC, don't get me wrong even after 3 years of working with RAC I find this book very useful. Here is a recap for the benefit of other readers.Chapter 2 covers the various hardware technologies available, the SMP architecture, SMP clustering, storage subsystems and the various types of cluster interconnects. A good comprehensive coverage of the hardware concepts on what is there and what to look forward to in areas of high speed interconnects.Chapter 3 covers Oracle concepts. I think this was a good presentation of Oracle technology especially because RAC is nothing but a combination of many single instances. This is probably the only chapter that is exclusively dedicated to Oracle single instance concepts. In this chapter the author has analyzed Oracle file and memory dumps to explain the concepts.Chapter 4 covers the RAC architecture, pretty detailed in-depth coverage, starting with the lock structures in RAC with the various background and foreground processes are covered in detail. Detailed discussion on the functions of GRD, GCS and GES, which are the backbones in a RAC architectureChapter 5 covers transaction management and behavior. The author has explained in detail the various transaction scenarios not neglecting the fact on how transitions are managed in a single instance configuration and covering areas that any developer/administrator should keep watch for when writing SQL statements to perform. This chapter has a great detail of fine tooth analysis.Chapter 6 covers parallel processing. This is the only chapter that I wish the author had provided more details. I wish he had provided some more in-depth details into parallel processing across instances without sacrificing details of parallel processing within an instance.Chapter 7 covers design considerations for RAC. The chapter discusses various database features that should be considered while designing for RAC not to mention that these features with the RAC technology will provide higher scalability. Apart from the index considerations, partitioning options the new sorted hash cluster feature coming in 10g has also been discussed.Chapter 8 Installation and configuration, the chapter was very helpful. I was able to give this book to a Junior DBA and based on the information contained in this chapter and Chapter 16 he was able to get a step by step jumpstart into the installation and configuration of RAC. The great thing about the entire book is its written in simple readable EnglishChapter 10 Availability and Scalability. It is an outstanding chapter. Provides details on how Oracle fails over, the various steps are analyzed and explaine
