• Fixes for over 180 bugs throughout the AHF stack, enhancing reliability and overall system performance.

Together, these updates provide a leaner, more resilient AHF experience, minimizing resource consumption while strengthening platform stability and performance.

Enhanced Diagnostic Collection: Command History Capture

Starting with AHF 25.10, AHF now captures the history of selected administrative commands, including kill, rm, find, chown, chmod, shutdown, reboot, and startup, run by different users across various shells.

This enhancement provides greater visibility into potentially relevant or suspicious activity, supporting faster and more accurate diagnostics. Command history is automatically included in diagnostic collections, improving the depth and accuracy of troubleshooting and root cause analysis.

Automated Problem Analysis for Node Evictions, Instance Evictions, and Database Slow Performance

Starting with AHF 25.10, Autonomous Health Framework (AHF) automatically detects new problems that result in instance evictions or slow database performance.

The detected problems and their recommended resolutions are displayed on the Problem Summary page, which is accessible from the Detected Problems panel in Insights.

This release introduces automated detection for the following types of problems, with corresponding resolutions shown in Insights:

• Instance evictions caused by ORA-29770 due to disconnected cell nodes in an Exadata cluster.
• Slow database performance caused by misconfiguration of RDS/IB network settings.
