Autonomous Health Framework (AHF) Version 24.6 Released

Oracle Autonomous Health Framework (AHF) is a diagnostic and system performance framework designed to keep database systems healthy and running while minimizing human reaction time.

It's the same technology Oracle uses in the cloud to keep the Autonomous Database running, and it's available for you at no extra cost as part of your existing software support agreement.

Autonomous Health Framework 24.6 is released and available to download

New Features in 24.6

Node Evictions & Performance Issues Are Easier to Resolve

AHF expands the causes of node evictions it can automatically detect and help resolve and can also identify some causes of performance problems. In addition each Problem Summary now includes relevant configuration details.

Since version 24.4 AHF has been automatically detecting Node Evictions and showing them in the Detected Problems panel of the Insights dashboard. From there you can drill down to a specific node eviction.

This release includes the ability to detect more causes of node eviction and adds Configuration details to the Problem Summary.

The Problem Summary contains:

  • Problem - including which node was restarted and at what time.
  • Reason - explaining why the node was restarted.
  • Cause - explaining the root cause.
  • Evidence - providing a bullet list audit trail detailing relevant OS and Database resource metrics, which were out of normal range leading up to the event.
  • Configuration - showing Database stack configuration
  • Resolution Steps - detailing in simple terms exactly how to resolve the problem.

Evidence is expandable, showing charts or log details to confirm the evidence.

AHF will generate a Problem Summary for the following causes of Node Eviction:

  • Memory exhaustion due to
    • HugePages are over allocated
    • Database or Grid Infrastructure process increasing memory usage
    • New Database started
  • Multipath disk failures

It will also generate a Problem Summary for hangs and performance issues caused by:

  • Archiver stuck
  • Latch contention due to misconfigured target_pdbs parameter

Future releases will continue to expand to identify more problem causes.

For more information on AHF Insights see the AHF user guide.

System Health Metrics Available on First Failure

AHF now automatically collects real-time system health metrics for non-clustered database systems, so they are available at first failure and includes them within diagnostic collections.

System health metrics such as CPU, memory and IO consumers are invaluable to Oracle Support for diagnosing Service Requests.

AHF now automatically captures System Health metrics, so they are available at the time of a failure and are included within diagnostics collections.

For more information on AHF System Health metrics see the user guide.

Component-Level Grouping of Events and Faster Performance

AHF Insights now includes the ability to view events grouped at a component-level and the home dashboard has been made even faster.

You can now explore timeline events grouped by Components, in addition to the existing Host, Events, and Database groupings.

This granular view allows for a more comprehensive understanding of how issues impact specific components of the Database stack, making it faster and easier to spot where the problems are.

The Insights report homepage has also been optimized to load even faster.

Insights reports are included within diagnostic collections or can be generated on-demand by running: 

ahf analysis create --type insights

New Exachk Best Practice Checks

24.6 includes the following new best practice checks for Exachk:

  1. Exadata Critical Issue EX88
  2. Exadata Critical Issue DB53

All checks can be explored in more detail via the Health Check Catalogs:
