Trouble-shooting or Tuning:
What's the difference? What are the strategies? Why tuning is hard but trouble-shooting is easy. Key targets, indicators and mechanisms for producing a well-tuned system on day one. Strategies for dealing with badly performing systems after go-live.

Frequently Occurring Problems:
Some of the most commonly occurring issues that affect performance after a system have gone into production. Methods for spotting them, measuring the impact, and dealing with the cost/risk/benefit triangle involved in fixing them. Getting into the habit of pre-emptive analysis and pro-active fixing.

Quick Fixes:
Methods, workarounds and dirty tricks for dealing with classic performance problems when the system is in production. There really aren't many quick fixes that can be applied across the board - each one needs careful examination of costs, risk, and benefits.

V$ and X$: It's a good idea to be familiar with just a few of the dynamic performance views - and there are a couple of items in the still hidden away in the X$ objects that can add a little value. This session will describe the views that are most commonly of use, and explain the meaning of some of the more obscurely named, but potentially useful items.
