This book is an entertaining, educational, and practical text that, surprisingly, is suitable for developers and DBAs of all levels. Like that other great book Optimizing Oracle Performance there is a theme about using a methodical approach. However, this book contains lots more technical information and is bang up-to-date with information on all recent releases of Oracle including 11gR1. I bought it in hardback and am very happy with my purchase.
Something's wrong here...a clearly written guide on performance tuning in the Oracle database? Tick. Good, to-the-point, easy to follow examples? Tick. Author clearly communicates his ideas? Tick. Covers lots of ground, from EXPLAIN PLAN and TkProf through statistics, common traps, solutions? Yup, tick.
