Excerpt. © Reprinted by permission. All rights reserved.

Each year, computer systems become faster. At the same time, memory and disk storage are becoming more plentiful and less expensive. Because of this, the means and the budget are now available to store vast amounts of information at relatively inexpensive prices. This has allowed users to increase the amount of data stored as well as increase the amount of processing that is done with that data. Because of this, society cannot simply solve performance problems by throwing more hardware at the problem. It's necessary to analyze, size, and properly configure systems to perform optimally.

For us, performance engineers, one of the problems that we see in the industry today is the introduction of large disk drives. At one time, it would have been necessary to configure 10 disk drives to hold the data that you have generated; you can now store the same data in 1 disk drive. What many people don't know is that this 1 disk drive is 10 times slower than 10 smaller disk drives. In this book, concepts such as this will be explained and explored.

Our philosophy in writing this book is that tuning must be done holistically. You cannot focus on one part of the system and achieve optimal performance. It is necessary to look at the application, the Oracle instance, the operating system, and the hardware and I/O subsystem to achieve optimal performance. In this book, we explore all areas of the system from SQL statements down to the operation of the disk drive.

We hope that you will use this book not only as a guide for learning Oracle performance tuning, but as a reference as well.How to Use This Book

To keep the book interesting, we have added some personal anecdotes relevant to the subject matter. We hope we have conveyed some of the excitement that comes when you push systems to their limits. Those of us who work in the database performance field constantly push the envelope of technology to achieve new levels of performance previously thought impossible. This kind of experimentation can be satisfying when everything works well, but frustrating when it doesn't.

Our hope is that, having read this book, you will have a basic understanding of how the components of the system work together to form the whole. If you have this foundation, you should be able to tackle a performance problem, know what to look for, and know how to fix it. Not all performance problems are alike, and solutions aren't either. It is important that you have a basic understanding of what to look for and what the possible solutions are.

If we have done our jobs correctly, you should finish this book with the ability to analyze the problem, hypothesize a solution, test that solution, and understand the result. We hope this book gives novices an idea of what performance engineering is all about. Seasoned professionals should receive new insight and ideas. By applying this newly acquired knowledge, you will find that tackling even the most complex performance problems can be broken down into simple, manageable tasks. 0672321467P04222002

Format: Paperback
If you want one book to help you figure out how to get better performance from your Oracle system, this is it. It is written for the real world, not to pass an exam. As such, it goes well beyond Oracle, clearly explaining how the underlying hardware and system architecture affect performance, including examples from the author's experience. Good overview of RAC also. A great value!

I am studying certification examination and I bought this book for studying 4th examination. I have 3 books on Performance Tuning subject and this one is total disapointment. In the book you can only see many repetitions (I think writers put these in order to increase page count) and useless commends. I could not find any detailed information on subjects, only well known regular information on Oracle database. If you do not want to waste your money, DO NOT BUT THIS BOOK.

I agree with previous reviewer. Starters may find this book little hard to follow. This book is best if used as reference. In other words you must be somewhat familiar with tuning expects of Oracle before nsidering purchasing this book and to benefit / improve or mastering Oracle tuning.
