Oracle performance analysts are always looking for ways to optimize the one thing database users care most about: response time. System performance inefficiencies commonly go undetected for months or even years even under intense scrutiny because traditional Oracle performance analysis methods and tools are unreliable. Optimizing Oracle Performance dispenses with database-centric metrics and instead shows how to use Oracle\'s response time statistics to diagnose performance problems in an Oracle application system. Former VP of Oracle\'s System Performance Group, Cary Millsap, clearly shows how eliminating requests for unneeded work improves performance dramatically. He also shows how the mathematical discipline of queueing theory can be combined with response time metrics to accurately predict the impact of system changes and upgrades. This is the timesaving method Oracle DBAs and developers have been waiting for.
