WA1386 Oracle Database 10g: SQL Tuning
Audience
Target audience for this course is both senior application developers and database administrators. Developers who will be building, debugging and tuning complex SQL statements will benefit from this course. Database administrators responsible for tuning the database will need to collaborate with application developers in order to implement the techniques discussed herein.
Course Objectives:
This course will equip developers to build efficient SQL statements and to tune applications from the standpoint of an application developer. When this effort is complemented by database server and possibly PL/SQL application tuning, then a highly efficient environment has been built. Major subject areas to be explored are:

• Consider the unique and differing tuning issues in OLTP database and data warehouse environments.
• Learn the phases of SQL statement execution within the database instance.
• Use various techniques to examine SQL execution plans which are produced.
• Learn about the operation of the Oracle Cost-Based Optimizer, including optimizer statistics and histograms.
• Influence the behavior of the Optimizer and tune SQL statement execution.
• Utilize the database advisory framework and those Advisors specifically intended for SQL tuning.
• Use private and public stored outlines to achieve absolute execution plan stability.
• Understand the self-tuning infrastructure and the automatic SQL tuning capabilities found within the database.

Course Prerequisites:

The following course is a mandatory prerequisite: ORACLE DATABASE 10G: INTRODUCTION TO SQL – COMPLETE LIBRARY.

While not mandatory, the following course is a suggested prerequisite which is helpful prior to completing this course: ORACLE DATABASE 10G: ARCHITECTURE FOR DEVELOPERS.

Certification Examination
This course considers subjects which pertain to the certification for an Oracle Certified Developer. Following the training sessions Oracle Corporation recommends six-months production experience with the technology prior to taking the certification examinations. While this is good practice it may not be necessary for all individuals.
About The Tuning Curriculum:

The context in which the subjects considered within this course is important to understand. By understanding the context one will be able to see the specific areas of focus in this course and the tuning and problem areas addressed by the other courses within the tuning curriculum. Therefore, please consider a brief overview of the tuning courses:

• ORACLE DATABASE 10G: SQL TUNING. This course considers tuning and monitoring techniques helpful in writing efficient SQL code and troubleshooting problem areas. These techniques are helpful whether the SQL statements are executed in isolation or as part of PL/SQL program units, Java classes, other 3GL programs, and so on. This is the course you are now taking.

• ORACLE DATABASE 10G: ADVANCED PL/SQL PROGRAMMING & TUNING. This course considers similar topics pertaining to PL/SQL program units. Obviously, any enclosed SQL statements which are also well tuned will contribute towards the efficiency of the application as a whole.

• ORACLE DATABASE 10G: ADMINISTRATION III – PERFORMANCE TUNING. The environment within which both SQL statements and PL/SQL program units execute is obviously the Oracle database. Therefore, if the efficiency of the database as a whole is compromised then the efficiency of any objects which execute within the database will similarly suffer. This course allows one to tune and monitor the performance of the overall database. A well-tuned and properly configured database environment offers the circumstances in which database applications, and their objects such as SQL statements and PL/SQL program units, will operate efficiently.
Duration:
Five days.
