Oracle Autonomous Health Framework (AHF) 25.11 Release Notes Summary

  • HugePages utilization diagnostic: A new HugePagesNotUtilized signature detects cases where HugePages are configured but entirely unused. It appears in the Orachk Cluster Health Monitor analysis, helping administrators identify memory-configuration problems quickly.
  • Select only required Exachk report formats: The new -output_format option lets you generate only JSON, HTML, XML, or a combination—for example, exachk -output_format json,html. This avoids producing unused formats and reduces both execution time and collection ZIP size.
  • Enhanced Exachk/Orachk activity logging: AHF now collects structured logs for runs, checks, environment details, and runtime activity. These logs support trend analysis and identification of recurring or high-severity failures, and are included in TFA collections. Logs rotate after 250 KB, with the latest ten runs retained.
  • Activity-specific Alert History: AHF consolidates relevant log and trace entries into a single chronological history for a given activity, such as a RAC shutdown or disk rebalance. The feature is enabled by default and can be generated with ahf analysis create --type alert-history.
  • New best-practice checks: Orachk and Exachk add checks verifying that DIAGNOSTIC_DEST uses a local filesystem for both ASM and RDBMS components.
