Oracle 11g SQL Performance Tuning for Data Warehouses
Duration: 4 Days
This course will provide the student with the skills necessary to create scalable, high performance SQL-based Oracle applications. They will also learn how to identify existing high-load, poor performing SQL statements and tune them. The focus is on making the best use of Oracle architecture, bench-marking various SQL formulations and identifying the best schema object for a given situation.
Oracle11g introduces "automatic tuning" features such as the Automatic Workload Repository, Automatic Database Diagnostic Monitor and SQL Tuning Advisor. These features will be included in the course. It will also include tuning PL/SQL programs using bulk processing and profiling to identify high-load statements. ETL consideration and physical modeling considerations are included.
