Oracle Optimizer One Day Workshop

Since its introduction in Oracle 7, people have been fascinated and intimidated by the Cost-Based Optimizer and the statistics it relies on. It has long been felt that the internals of the Optimizer were shrouded in mystery and that a degree in wizardry is required to be able to make it do the right thing. This one day workshop will explain the fundamentals of the cost based Optimizer and the statistics that feed it, as well as providing a methodology for diagnosing and resolving SQL execution performance problems.


Training Day will begin at 8:30 a.m. and end at 4:45 p.m.
