Inside the Oracle 10g cost based SQL Optimizer

With each new release of Oracle, the cost-based SQL optimizer (CBO) becomes more intelligent and Oracle10g is no exception.  This presentation shows the major enhancements to the cost-based SQL optimizer in Oracle10g with a focus on the tuning tools that affect the behavior of the CBO.  Topics will include the CBO Oracle parameters, the use of schema statistics by the CBO, and how the CBO evaluates complex queries and derives the optimal execution plan.  We will also cover the use of the new 10g SQL profiles and discuss cursor sharing and automatic query re-write.

Presented by the author of High-Performance SQL Tuning by Oracle Press, this presentation is indispensable for all Oracle professionals who must understand how to adjust their CBO for optimal performance in their environment.

Key Points:

- Understand Oracle costing trees

- See the parameters that effect CBO behavior

- Learn about optimizing schema statistics

- See why histograms help the CBO make better decisions

- Understand SQL dynamic sampling

This has been a top-rated presentation and is very popular at local Oracle user groups.
