Let’s Build Something! Building Your Own ASH Toolkit

• Learn by doing • There is still no better way •

Let's build something... of value! ASH provides Oracle DBAs with an amazing set of performance data. Because ASH analysis is based on sampling, many DBAs shy away from ASH or use it inappropriately. But once you're in-the-know along with a few simple but powerful scripts, your performance tuning potential becomes scary-strong.

In this video seminar, Craig shows you how to build three highly flexible ASH-based scripts: summary, top anything and session time-line. Throughout the seminar Craig explains and demonstrates scripts on a real Oracle workload. Whether you use these scripts or not, you will have a very deep understanding about ASH and how to effectively use it.
