This course provides students with a thorough, behind the scenes look at Oracle application tuning. A discussion of basic Oracle architecture will provide the foundation for understanding both SQL statement and system performance. Students will use EXPLAIN PLAN and AUTOTRACE for evaluating execution strategies and understand the importance of object statistics. Also discussed is how to influence the behavior of the optimizer with hints, physical schema changes, and alternative SQL statement syntax. Factors that affect overall system performance such as the buffer cache, other SGA structures, indexes and waits due to locks and latches are presented. Hands-on workshops provide students with a solid understanding of the concepts presented in the lectures.
