Oracle's databases are probably the most commonly used enterprise relational databases. The latest version, 8i, is rapidly rolling out and this thin book is intended to help you get the most from it.
A complex RDBMS like Oracle can almost be seen as an operating system in its own right, with a kernel controlling all its operations. Steve Adams looks in detail at five different components of this kernel, and how they effect the performance of your databases. You'll find out about how to understand the statistics that you can extract from 4the server, and how you can fine-tune these components to get the most out of a busy server.
Oracle8i Internal Services for Waits, Latches, Locks and Memoryrefers regularly to the author's own set of scripts used to gather information from the Oracle kernel. It's a pity that the source code of these isn't included in the relevant chapters, as they would aid in understanding how you can develop your own tools for acquiring and using Oracle's internal information.
If you want to learn about Oracle, this isn't the book for you, as it deals with complex performance tuning issues. You'll need to be an experienced Oracle administrator to get the most out of this book--and you'll probably want to download the recommended scripts from the O'Reilly web site in order to use them in your own database management scripts. -- SimonBisson
About the Author
Steve Adams runs a small consulting company, Ixora, that specializes in advanced Unix and Oracle performance tuning. He is based in Sydney, Australia, but also works remotely for clients in America and Europe. Steve is a regular contributor to various Oracle discussion forums on the Internet, where he is widely regarded as the leading performance expert. His experience with Oracle dates back to version 3 (1984). However, most of his work has been in Unix performance tuning. His interest in Oracle--and Oracle internals in particular--was rekindled when working as the Unix performance expert on a benchmark of an Oracle-based application in 1995. He found the challenge of understanding Oracle performance to be extremely demanding, and yet irresistible. Steve doesn't yet claim to have mastered the topic of Oracle performance, but he does have plenty of insight to share. He can be contacted directly at firstname.lastname@example.org or via his company's web site at http://www.ixora.com.au/.

It reveals a lot more about the inner workings of Oracle than the official product documentation or any of the Oracle Press books would dare.
New or trainee DBAs will not get anything out of the book because unlike the Oracle Press door stops, which try to cater for all it is targeted specifically at expert DBAs.
Excellent value for money.

My wishlist notwithstanding, this book merits five stars because it provides a wealth of information and knowledge that you just can't find elsewhere. If you're an Oracle DBA you need this book.
Having several books about tuning Oracle server on my bookshelf not a single one goes deeper in the explanation than this thiny one. We can only imagine and appreciate the time and knowledge that Steve Adams invested in this book.
One reminder to those of you who are searching for the definitive tuning guide ("do that, change that..."); Oracle8i Internal Services is not about that, here is what author wrote in the preface ..."My advanced Oracle performance-tuning book is still a dream. This little book is something else: an introduction to Oracle internals. It builds the foundation necessary for advanced performance tuning..."
There is only one thing that this book badly need - pictures! So Steve if you're reading this please include some pictures in your second edition (I hope there would be one!).
Adams knows how Oracle works and explains the waits, latches and locks pretty well. I especially liked the chapter on Memory.
I learned a lot from this book. This was money well spent.
