Performance Monitoring Experts

COURSE DESCRIPTION:
This is a 5-day class (6-hours per day) that includes lecture, lab and testing for up to 12 students.

Attendees will learn tips and techniques on how to advance their expertise when programming in SQL and PL/SQL.  They will learn tuning tips and debugging techniques.
 
The attendees will work with a variety of SQL statements and tune them by making coding changes based on their review of the explain plans, modifying indexes and using hints and coding style to control the explain plans.  They will also learn how to use tools such as index monitoring, SQL Trace and the PL/SQL profiler.  They will be instructed on how Oracle selects indexes, why they are sometimes not used and how to tell which indexes are being used or not.

 The attendees will find poorly-performing components of PL/SQL routines, use Oracle's DEBUG routines to find problems in PL/SQL logic and will learn how to use PL/SQL's new optimizing compiler and collections.  Students will learn how to use Toad when performing the hands-on exercises.


Lectures and topics are enhanced with live illustrations and hands-on exercises.

 COURSE OBJECTIVES:

  1. Introduction to Explain Plans and Hints.

  2. Introduction to Cost-Based Optimizer.

  3. Understanding Indexes.

  4. Introduction to Tuning Tools:  SQL Tracing & TKProf

  5. Learning SQL Coding Tips.

  6. Learning PL/SQL Coding Tips.

  7. Review of PL/SQL syntax and language structure.

  8. Review of cursor management.

  9. Review of PL/SQL Profiling.

  10. Review of Package Usage (User Defined and Oracle Defined)

  11. Exposure to Quest Software's application named Toad.

  12. Introduction to advanced PL/SQL topics including compiler options, code encryption, conditional compilation, collections, triggers, dynamic SQL and much more.
