AIOUG Webcast: The Basics of Cost Based Optimization - Part II by Jonathan Lewis
Jonathan Lewis will be presenting part-2 of "The Basics of Cost Based Optimization" on 09-June-2010 at 14:00 GMT. About the Presentation: This presentation is a short introduction to the two key questions that drive the optimizer which are: How much data do I have to visit How widely scattered is that data We will look at a simple model to demonstrate the way that the optimzer "thinks" when choosing an execution path, and then explain why the optimizer sometimes chooses very silly execution paths.
