Oracle SQL Tuning for Developers Workshop NEW

In this application development-centric course, you'll explore Oracle SQL statement tuning. Learn how to write well-tuned SQL statements appropriate for the Oracle database.

Learn To:

• Interpret execution plans and the different ways in which data can be accessed.
• Decipher, decide and then apply tuning to SQL code.
• Use various tuning techniques.
• Take advantage of bind variables, trace files and use the different types of indexes.
• Use different access paths for better optimization.

Benefits to You

Ensure fast, reliable, secure and easy to manage performance. Optimize database workloads, lower IT costs and deliver a higher quality of service by enabling consolidation onto database clouds.

Understand Basic Tuning Techniques

Expert instructors will also teach you how to rewrite queries for better performance. Furthermore, you'll learn how to utilize SQL Tuning Advisor using SQL Developer 3.0.
