Famous Steve Adams book ‘Internal Oracle 8i Services for Latch, Locks and Enqueues’ was published 10 years ago on October 1999. This book founded new era of Oracle performance tuning and internals research.
The book opened for us the unknown world of Oracle Internals. Even now, after the decade it is an ultimate reference for many Oracle latch and lock related topics. For ten years we fight with the latch concurency using Steve Adams recipes. There were even rumors that this book was used inside Oracle as the manual. In particular, Oracle University Data Server Internal Seminars, has a lot of parallelism with this book. Everyone who seriously dive into this topic always should read it.
But the Oracle latch technologies were evolved greatly during the last decade! We need the contemporary knowledge.
Latch, mutex and beyond
