#tanelpoder #AOT20 #AST E2SN "Performance Tuning" Oracle

In my earlier post I me wrote about #222222; line-height: 16px;">#2288bb; text-decoration: none;">Tanel Poder's Virtual Class #2. #222222; line-height: 16px;">Tanel is a world famous expert in Oracle internals. I was fortunate to be able to attend the class on all days except Friday. It was solid 4 hours of learning every day. Let me summarize some of the key points I appreciated as an attendee. I hope it will be useful for you making a decision to attend one later.

What are good ways to learn about the inner workings of Oracle to troubleshoot performance and availability issues?

Fortunately there is only one good answer - just one good source - Tanel Poder's virtual seminars at http://tech.e2sn.com/oracle-training-seminars

Why? Let's examine the typical objectives and the various means to accomplish them. I'm sure you have heard this complaint before - "the database is slow". If I had a dime every time I heard it, well ... you know the rest! Most DBAs by now know the next best thing they should do - check the wait interface - V$SESSION. That's a very good first step.
