[From O'Reilly Network]
In this O'Reilly Network Weblog, Jonathan Gennick discusses his experience at a recent Hotsos Clinic on diagnosing performance problems in Oracle systems.
Comments from Gennick include:
"It's a great clinic, highly recommended. It stands out as one of the two best database courses I've ever attended (the other was a DEC/Rdb Internals course that my boss at the time accidentally sent me to in 1992)."
"[Teachers] Cary Millsap and Jeff Holt are very rigorous, and they approach their work in a very scientific manner. They spent a good part of the first day debunking the cache-hit ratio and all the other ratios that DBAs have been taught to rely on as performance-tuning aids...They also took time on the first day to emphasize the business aspects of tuning."
