Overview

Oracle Autonomous Health Framework is a collection of components that analyzes the diagnostic data collected, and proactively identifies issues before they affect the health of your clusters or your Oracle Real Application Clusters (Oracle RAC) databases.

Most of the Oracle Autonomous Health Framework components are already available in Oracle Database 12c release 1 (12.1).

Oracle Autonomous Health Framework Problem and Solution Space

Oracle Autonomous Health Framework improves availability and performance by applying best practices, collecting first-failure data, monitoring servers, databases, I/O, and networks, detecting emerging issues, notifying administrators, and recommending corrective actions. It addresses server availability threats such as interconnect congestion or failures through CVU, Cluster Health Advisor, Cluster Health Monitor, and TFA; database availability problems such as resource contention, attacks, defects, and configuration errors through Blocker Resolver, Orachk, CVU, TFA, and diagnostic monitoring; and performance problems caused by configuration deviations, blocked sessions, unpatched defects, or client resource settings through Orachk, Blocker Resolver, and Cluster Health Advisor.

Components of Autonomous Health Framework

Oracle Autonomous Health Framework includes Orachk and Exachk for proactive health, compliance, configuration, and known-issue checks; Oracle Trace File Analyzer for automated, targeted first-failure diagnostic collection; database attention logs for structured administrator-focused events; AHF Insights for offline, consolidated reports covering configuration, topology, metrics, logs, anomalies, root causes, and recommended fixes; Cluster Health Advisor for continuous model-based monitoring, early warnings, diagnoses, corrective actions, calibration, and historical analysis; AHF Scope for interactive real-time or archived CHA analysis, though it is deprecated in Oracle AI Database 26ai; AHF Balance for analyzing cluster CPU consumption and recommending Database Resource Manager settings; Cluster Health Monitor for recording cluster and operating-system metrics; and Blocker Resolver for detecting and automatically resolving database delays and deadlocks.
