Oracle Autonomous Health Framework (AHF) helps maximize application resilience, performance, and security through issue prevention and resolution.

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 24.10 is released and available to download

 

New Features in 24.10

 

Detect New Causes of Database Slow Performance

AHF now automatically detects new slow database performance problems, showing a summary of the problem, cause and resolution in Insights.

Since version 24.4 AHF has had the ability to detect problems and show a summary with the resolution. The Problem Summary page is available under the Detected Problems panel in Insights.

This release adds the ability to automatically detect the following new problems:

Slow database performance caused by:

  • Generic IO error

Node evictions caused by:

  • Poorly sized UDP buffers
  • Misconfigured UP reassembly buffer parameters

To generate a diagnostic collection run:

Copied to Clipboard
Error: Could not Copy
Copied to Clipboard
Error: Could not Copy
tfactl diagcollect

Then follow the prompts to select the issue of interest.

Transfer the resulting zip to a machine with a browser, open the Insights report and view the Detected Problems.

See the user guide for more information on resolving problems AHF has detected.

 

Explore Event Context with Insights File Viewer

Clicking an event on the Insights timeline now opens the corresponding log entry within a new file viewer.

The AHF Insights timeline shows all important events relating to the database and puts them in context relative to each other. But, sometimes it is useful to be able to also browse the relevant log file.

Insights now includes a new File Viewer. Clicking any log event in the Timeline opens the corresponding file at the event location.

Once opened the full contents of the log file can be browsed and easily searched.

AHF Insights now includes an option to send feedback directly to the development team.

DBA’s, Sys Admins, Cluster Admins and Architects all use AHF Insights to help understand Oracle Database diagnostics.

Insights reports are included in all diagnostic collections on all systems and help to understand things like:
