Oracle system performance inefficiencies often go undetected for months or even years--even under intense scrutiny--because traditional Oracle performance analysis methods and tools are fundamentally flawed. They're unreliable and inefficient.Oracle DBAs and developers are all too familiar with the outlay of time and resources, blown budgets, missed deadlines, and marginally effective performance fiddling that is commonplace with traditional methods of Oracle performance tuning. In this crucial book, Cary Millsap, former VP of Oracle's System Performance Group, clearly and concisely explains how to use Oracle's response time statistics to diagnose and repair performance problems. Cary also shows how "queueing theory" can be applied to response time statistics to predict the impact of upgrades and other system changes.Optimizing Oracle Performance eliminates the time-consuming, trial-and-error guesswork inherent in most conventional approaches to tuning. You can determine exactly where a system's performance problem is, and with equal importance, where it is not, in just a few minutes--even if the problem is several years old.Optimizing Oracle Performance cuts a path through the complexity of current tuning methods, and streamlines an approach that focuses on optimization techniques that any DBA can use quickly and successfully to make noticeable--even dramatic--improvements.For example, the one thing database users care most about is response time. Naturally, DBAs focus much of their time and effort towards improving response time. But it is entirely too easy to spend hundreds of hours to improve important system metrics such as hit ratios, average latencies, and wait times, only to find users are unable to perceive the difference. And an expensive hardware upgrade may not help either.It doesn't have to be that way. Technological advances have added impact, efficiency, measurability, predictive capacity, reliability, speed, and practicality to the science of Oracle performance optimization. Optimizing Oracle Performance shows you how to slash the frustration and expense associated with unraveling the true root cause of any type of performance problem, and reliably predict future performance.The price of this essential book will be paid back in hours saved the first time its methods are used.

This is an Oracle classic....
By Robert G. Freeman
In a style that will be appreciated by the beginner, intermediate and advanced DBA/Developer, Cary and Jeff introduce the reader to the world of the Oracle wait interface. This book has depth, the contents are full of meat, and it's not a rehash of every other Oracle book published in the last 10 years. In these pages is something for everyone. Cary introduces the wait interface, and how it can be used for tuning. The book presents the topic in a clear and concise fashion.
The book is full of detail such as concise information on the internal workings of Oracle trace files and how to use them to your advantage when tuning your Oracle database. They demonstrate the power of the 10046 event and it's potential.
Putting all of this together into a performance tuning method he calls Method-R, they lead us from tuning by guess work into a world of facts and using accurate measures to generate appropriate tuning responses.
This book IS required reading for any DBA who wants to be elevated to the level of a tuning deity. I've already dog eared a goodly number of pages!

DO NOT READ THIS BOOK
By Richard L. Rankin
I want to have an advantage over all the other Oracle DBAs! I've been reading Cary Millsap's papers since the 70s and always found them to be right on the money. His VLDB paper is a classic. He is THE Oracle guru. I'm only half-way through the book and consider it money well spent.

Performance tune Oracle to a new level
By Michael H. Thomas
Another reviewer mentions "this book fills in all the gaps in analyzing Oracle performance that exist in other published works", and I disagree. This book creates gaps in most other Oracle performance analysis books. This is a tremendous book.
Some difficult material that is covered with detailed and simple explanations. If you can read and follow through with the examples you will definately come to understand even these parts.
The gaps Millsap and Holt create in other Oracle performance tuning books are 'assumptions', 'generalizations' and 'inaccuracy' because this book teaches the reader how to precisely identify user's Oracle performance problems, and exactly what to fix.
Having read this book in depth, I'll continue by saying this book also shows how to fix Oracle Performance problems. But, I almost guarantee if you are not prepared to learn the material, and follow the Method R, you may disagree this book shows 'how'.
This book is five stars because its the only reference currently available (first of class in my opionion) that provides 100% business value to Oracle performance tuning of existing systems (Oracle 7 through 10). Experience Oracle DBAs and Developers may have problems with this book because it will cause you to think about Oracle Performance in a new, refreshing way by directly improving user's response times.
Hopefully, you will read this book with an open mind and capture why Method R is so powerful to solve all sorts of Oracle performance tuning problems. Great job Millsap and Holt.
