Summary: A must for advanced tuning and trouble-shooting
Review: Wait events are often the key to understanding 'what is going on' when Oracle performance problems occur during run time. This book does a great job giving an overview of the complex Oracle internals that underlie these wait events. Now, if you don't know what wait events are, this is not the book for you. There are a few criticisms of this book, but they ignore the fact that this book is the first substantial overview of this often nefarious subject. Many, including myself, had attemtped to piece together the internal workings of Oracle using Oracle internal documents, speaking with Oracle developers, empirical tests, etc. with limited success. This book was a welcome relief and quite an eye-opener.

Summary: Good look into Oracle internals
Review: Yes, the book was written when Oracle 8i was around, but it is well worth the read even today.
Adams knows how Oracle works and explains the waits, latches and locks pretty well. I especially liked the chapter on Memory. Honestly, I learned a lot from this book.
For me, this was money well spent. I highly recommend this book.
