Oracle Cluster Health Advisor – How It Works & How to Use It

What if Oracle RAC database issues were detected before they had an impact? What if you were notified with a specific diagnosis and corrective actions?
Learn how diagnosing and resolving over 30 of the most common Oracle RAC database problems no longer requires extensive knowledge of not only database internals but networking, storage and O/S interactions.

This session will present a technical deep dive into the new Oracle Database 12c/Rel. 2 Cluster Health Advisor (CHA) and how it continuously analyses database ASH/AWR data and network, storage and O/S metrics to provide early warning and targeted resolution using machine learning. This session will explain its adaptive learning and prognostics design, the scope of the problems it diagnoses and use of this new feature including calibration to your workloads. Walkthroughs of its runtime use with actual issues using the new CHACTL utility and standalone Java GUI tool as well as integration with Enterprise Manager Cloud Control 13c will be included. The session will conclude with best practices on improving CHA prognostic sensitivity by creating and calibrating custom models that track your normal workload phases. Agenda will include:
- Introduction
- CHA Architecture and Operation Details
- Using CHA from the Command Line
- Using CHA from EMCC for Alerts and Corrective Actions
- Using the CHA GUI to Perform Root-Cause Analysis
- Calibrating CHA to your RAC deployment
- Q&A – Further Information
