This is an outstanding book written by three outstanding individuals! A massive piece of Response Time Analysis is effectively and responsibly using Oracle's wait interface. My Advanced Reactive Performance Management course in conjunction with this book will help you get the most out of the wait interface. I was one of this book's technical reviewers so I can personally vouch for the accuracy and depth of this book. It should be in every DBAs library and is a must read.

Obviously, you can not download this book. The Amazon.com link is here.
