This course, delivered as a self-study CD-ROM, familiarizes learners with various tuning methodologies for optimizing SQL performance and improving response time and scalability. This course offers the tips and tricks for proactively tuning Oracle databases and optimizing SQL performance.

Students gain an understanding of the new automatic tuning methods included in the Oracle 10g release, together with the manual tuning steps used in previous releases. Students are then taken through a thorough review of Oracle Optimizer, including how to change the physical schema and modify SQL statement syntax. Learn how to use Oracle diagnostic tools and facilities, including EXPLAIN, SQL Trace and TKPROF, SQL *Plus AUTOTRACE.

Throughout the course, students experience SQL tuning of an Oracle 10g Database through a series of simulated demonstrations.
