Course Description

About The Course
What is 11g: SQL Tuning Workshop Certification Training about? This Oracle Database 11g: SQL Tuning Workshop Release 2 training assists database developers, DBAs and SQL developers in identifying and tuning inefficient SQL statements. You'll explore investigative methods to reveal varying levels of detail about how the Oracle database executes the SQL statement; this helps you determine the root causes of the inefficient SQL statements. Gain expertise in relational database data management as you learn how to effectively use SQL commands against your business data.These features will help you query and manipulate data within the database, use the dictionary views to retrieve metadata and create reports about their schema objects.
Expert instructors will also help you explore how the optimizer chooses the path. You'll also learn how to influence the optimizer to ensure the best method is used.
This course covers Automatic SQL Tuning tools and resources available in the Automatic Workload Repository. Furthermore, take advantage of bind variables, trace files and different types of indexes.
Note: this course is based on Oracle Database 11g Release 2.
