Optimizing Oracle Performance dispenses with database- centric metrics and instead focuses on the issue of analyzing the database's response time to all of the different sorts of requests made of it. Former VP of Oracle's System Performance Group, Cary Millsap, clearly shows how eliminating requests for unneeded work improves performance dramatically. Cary also shows how the mathematical discipline of queuing theory can be applied to remove the guesswork, frustration, and expense associated with determining the true root cause of any type of performance problem.
