Course Description
Overview
This Oracle Database 11g R2: SQL Tuning, Architecture & Internals course is designed to provide students with an understanding of the underlying architecture of the Oracle database environment. It is also intended to help information technology (IT) managers and executives who require an understanding of the technology upon which they and their staff rely. This course module will frequently show the component as it is actually rendered by the Enterprise Manager graphical interface for database administrators. At other times this course will use the SQL command-line interface to explain the characteristics of the architectural component being discussed.The 'SQL Tuning' volume will equip database administrators and application developers to build efficient SQL statements and to tune database applications. When this effort is complemented by database server and PL/SQL application tuning, then a highly efficient application execution environment is created. One will learn about the internals of SQL statement execution, how to monitor the performance of such execution, and how one can influence the behavior of the database to achieve performance gains.
This course covers information relevant for the certification test EXAM 1Z0-054: ORACLE DATABASE 11G R2: PERFORMANCE TUNING.
