Optimizing Oracle Performance. Other Oracle resources from O’Reilly. 12 Chapter 1: A Better Way to Optimize. Response time is an objective measure of the interaction between a consumer and a provider. Consumers of computer service want the right answer with the best response time for the lowest cost. Your goal as an Oracle performance analyst is to minimize response time within the confines of the system owner’s economic con-straints.

Optimizing the performance of an Oracle database . In Optimizing Oracle Performance, renowned Oracle scientists Cary Millsap and Jeff Holt break.

Optimizing the performance of an Oracle database, or of a system running atop an Oracle database, has long been somewhat of a black art. Database administrators have been taught to rely on utilization statistics such as buffer cache hit ratios. Clearly, performance optimization seems like a hard problem, but is it really? In Optimizing Oracle Performance, renowned Oracle scientists Cary Millsap and Jeff Holt break new ground by describing a reliable, repeatable, and deterministic method for isolating system performance problems. Gone are the days when you had to rely on a bag of random tips and techniques.

In Optimizing Oracle Performance, 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.

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 book covers Oracle 8 and 9. But its technical explanations are very much valid for Oracle 10g.

    Although the author's beautiful explanation of 10046 traces and waits are worth its weight in gold, much of the information could have been condensed into fewer pages. Regrettably, most of the book are fillers. The author tries to explain much of his thoughts in mathematical formuls (nothing difficult) but it didn't add to the comprehension of the topic.

    One thing which made this book stand out was the problems and exercises at the end of each chapter. They were helpful, and unique among Oracle books, in enabling the reader to understand the topic more thoroughly.

    Overall, I recommend this book. But I have read better, and more comprehensive, books on the Oracle performance.

  • 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.

  • 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.

  • It's surprising how often people say things without knowing what they're talking about. That's a good, short description of almost everything that's been said about Oracle tuning over the last 15 years.
    Surprisingly, the facts about tuning Oracle are pretty simple. Most of the results you will achieve come from doing one thing -- tuning individual SQL statements.
    The author of this book is one of the few Oracle experts around, and he has created a product called HOTSOS, which is essentially an enhanced version of TKPROF. At times this book reads like the world's best infomercial, designed to promote the author's product.
    Still, 99% of Oracle professionals will benefit from this book, even if you don't buy the author's product. It explains very clearly how to DIAGNOSE Oracle performance problems, and it shows an entire approach to tuning that's invaluable.
    By the way, there's absolutely no need to know calculus or any other advanced math to understand this book. This rumor apparently got started by some blowhard, pretending to be an expert, but mainly interested in self promotion and telling the world, "I know calculus!" In fact, anyone with basic knowledge of SQL could understand this book and benefit from it.

  • This book delivers on its promise to open up a new world of analysis and tuning to most DBAs. The concepts, calculations, and methods it provides are excellent. As an experienced tuning consultant I had used some of these methods in the past but this book brings them all together.

    The book is written in a style which is enjoyable, scattered through with "war stories" and experiences which illustrate good points.

    This book is not just another script book. The author not only shows you how to tune using his method but also explains why that method works. There are complex calculations included in the descriptions but it is not necessary to know higher math to use this process. No matter what method you use for tuning SQL and Oracle instances, there is material in this book which will enhance your understanding and your tuning toolkit.

  • I was amazed at the amount of equations in this book. It is a very theoretical text and has gads of illustrations for internal timings and other super-detailed information.
    I'm going to have to read it at least twice to fully-appreciate it, and I fear that some of the theory will not apply to my systems.
    The only objestion I saw is that there was very little material on solutions, and the book focus is on finding issues, with not enough about how to fix the problem. Other than that, I was satisfied and commend the author for writing what surely must be the most theoretical and mathematical Oracle book anywhere.

  • This book is so interesting that on a couple occasions I've fallen asleep reading it, because I want to "find out what happens next" -- not because it is boring. Even the chapter on queueing theory that has a lot of math in it is understandable and interesting, even though I have a mild aversion to math.

    It has highlighted a lot of very useful techniques to ensure you focus on the true problems, and not the various ratios we've taken as absolute truth for so many years. I can't wait to try these concepts out!
