Expert Oracle Exadata (Expert's Voice in Oracle) Paperback – 9 August 2011

Their are only a couple of books on Exadata and this one is certainly the best one. Their are approximately 3000 Exadata installations per Oracle Support Mgmt. When I was researching which Exadata book to buy I only found 3 or 4 other books. I read excerpts from the other Exadata books and they do not go into the level of detail that Expert Oracle Exadata goes into. The authors are well known in the industry and the book is well written. The only issue I have is that I am working on Exadata X3 and this book was written for the X2. Obviously this does not reflect on the quality of the book and most of it does apply to the X2.It would have been nice to have a chapter on ZFS and using ZFS to backup Exadata. Many Exadata implementations use ZFS because it is the only back solution (currently) that will plug into the Infiniband network on Exadata. It is the fastest way to backup Exadata at several Terabytes per hour.Most of the chapter on parallel execution can be applied to non-Exadata and it does a great job of explaining new features in 11g.The most important chapter is Chapter 2. After reading this chapter you will know how to determine if Smart Scans (aka offloading) are working for your SQL. The book will give you a few ideas on how to modify your environment to enable Smart Scans and see if they help or not.Chapter 10 covers wait events and it also a very important chapter. The wait events that are specific to Exadata are documented here with examples and comparisons to non-Exadata DBs. The examples include SQL traces that help you determine if Smart scans are working or not.

筆者のTanelPoder氏が気になっていたので、Exadataの仕事をすることになった際に購入しました。ネットでの情報は断片的であったり、概要であったりとまとまった理解がしづらいですが、この本は体系的にExadataを学ぶことができます。

Given that when Exadata came out this guy (and a few others) simply decided they would get an Exadata and take it apart, I would think they could write a good book. The book lives up to the authors reputation. A must have for anyone using an Exadata at any level.

I've been a DBA for 30 years and dealing with Oracle for about 19. I like to read a lot and love to know more and more of Oracle even if the subject is not part of my daily life, as Exadata. This book does grasp the attention. It is deep (the way I like) and we can see the author does know what he talks about. The level of details is very adequate and precise. I could understand Exadata very well and feel prepared to work with it one day.

Whew, this was a most difficult read to get through. Granted, I started this book knowing little about Oracle and nothing about Exafata.Now, I am not sure if I want to know.I gave it a 3 as I know the authors worked hard on it but it was a confusing read.There were lots of jumping around and lots of code pages that were very confusing. Some of the jokes used in the book for levity purposes were off-color and would not have been missed.
