Oracle11g Application Tuning

This course provides students with an introduction to application and database tuning. Students will learn how the cost-based optimizer works. 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 the DBMS_STATS package for gathering optimizer 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, SGA structures, 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.
Students should have experience with Oracle11g Database Administration or Oracle10g Database Administration.
