In this crucial book, Cary Millsap, former VP of Oracle ' s System performance Group, clearly and concisely Use Oracle ' s response time statistics to diagnose and repair performance problems. Cary also shows how "queueing theory" can is applied to response time statistics to predict the impact of upgrades and oth ER system changes. Optimizing Oracle Performance eliminates ti
