Dynamic Queries use many memory resources to back dynamic statement caches, buffer pools etc.. The new 64bit systems offer a large amount of tuning opportunities, and many possibilities to waste memory.This presentation takes you from an overview of cache usage, dives into the caches to detect meaningfuel information, comes up with a 'memory efficiency score', and shows you how to estimate the benefit you could expect if you would install 2GByte of additional memory.All with a specific focus on dynamic SQL queries.
