Database Time-Based Performance Tuning: From Theory to Practice

In this 2014 OpenWorld session, Graham Wood covers how you can identify bottlenecks and maximize database performance with Oracle’s unique database time methodology. It covers a rich toolset at the disposal of DBAs—from Oracle Enterprise Manager 12c’s Automatic Workload Repository and Active Session History features to Oracle Database’s Automatic Database Diagnostics Monitor feature—and how these tools work together seamlessly. The session also provides an in-depth understanding of how the database time methodology is used in Oracle Enterprise Manager to provide a simple yet effective method to diagnose and resolve performance problems with just a couple of mouse clicks.
