Complete 2010 Hotsos Education Calendar Posted

The complete calendar for Hotsos Education for 2010 has been posted at We are pleased to announce a brand new class entitled Advanced Optimizer Concepts and Performance, which will be offered starting in April.

A thorough understanding of the Oracle Cost-Based Optimizer (CBO) is essential to consistently optimize SQL in a timely manner. Our Optimizing Oracle SQL, Intensive class teaches students a repeatable and reliable systematic method for optimizing SQL, and the underlying knowledge of that methodology is an understanding of the CBO. However, it's impossible to pack a lifetime of information and learning into 5 days. Therefore we've developed Advanced Optimizer Concepts and Performance as the next step in learning more about the CBO.

This new class will help you answer the following questions:

  • "What does that cost number mean?"

  • "How did the CBO calculate that cost?"

  • "Does a lower cost plan ensure better run time performance?"

  • "I see a great access path. Why doesn't the CBO use it?"
