Hi,

I have to agree completely with the previous reviewer. This book was badly named. It started out with a description of disk drives. Ok, fine, I don't mind a little review. But the review was still going on by page 100. The book only contained some brief and minor discussion of Oracle. There was one table from metalink on RAID recommendations from Oracle. There are only two chapters in the whole book that have the word "Oracle" in the title. One of them is on solid state disks and the other is called "Oracle 10g Disk Related Features" but is only about ASM.

Disappointing

This book has a wrong title. I thought it would provide good material about tuning oracle disk i/o performance at expert level, but actually it is an introductory book on how disks work in general. It has a cheating title. Fortunately it's not that expensive.

Because disk I/O is the main issue with Oracle this is a most-needed book and one that I recommend because it is through and has details about how to tell when disk is a problem and when you can monitor and fix disk I/O in Oracle databases.

I'm an unabashed fan of Mike Ault and I have every one of his books. Mike has always emphasized the importance of disk I/O in Oracle tuning and I'm glad to finally have a whole book on the topic.

The text is very Oracle-centric, concise and shows all of the areas where Oracle performance declines from a bad disk layout. Rather than just being an overview, Ault dives deep into the I/O internals and shows at a microscopic level how Oracle interacts with the disk I/O sub-system.

This is one of Mike's best books in years, and that's really saying something.
