Given unpredictable workload mixes, even in the cloud environment, rare and random short-lived performance incidents can occur. These incidents present DBAs with a challenge. In this presentation, I begin with why ASH (active session history) is so powerful, how it works and how we use ASH to analyze complex performance incidents. Using only four free scripts, I will lead you step-by-step through the incident analysis process. Plus, I will show you how to visualize a performance situation using the free statistics package R.

If you want to learn how to use ASH to solve random short-lived performance incidents, you will find this presentation very valuable.
