Enhancing Database Performance Tuning with Enterprise Manager 12c

This agenda outlines key strategies for optimizing database performance using Oracle Enterprise Manager 12c. We will discuss important features such as Active Session History (ASH) analytics, fine-grained filtering, and emergency monitoring capabilities. Attendees will learn how to analyze performance issues, drill down to root causes, and leverage new functionalities to streamline database management. A case study highlighting slow response times due to high I/O and network delays will be presented. Join us to explore advanced performance tuning techniques and tools for improved efficiency and user satisfaction.
