Oracle Autonomous Health Framework (AHF) 24.6 Release Notes Summary

  • Expanded automated problem detection: AHF Insights adds detection and resolution guidance for node evictions caused by HugePages over-allocation, rising database/Grid Infrastructure process memory, new database startup, and multipath disk failures. It also covers hangs from blocked archiving and performance issues from an incorrect target_pdbs setting.
  • Richer Problem Summaries: Problem Summaries now include configuration context in addition to the problem, cause, evidence, and resolution steps. Evidence can be expanded into relevant charts and log details.
  • First-failure system metrics for standalone databases: AHF automatically captures real-time CPU, memory, I/O, and top-consumer data for non-clustered database systems, preserving it in diagnostic collections for support investigation.
  • Installer preservation for downgrade: The new ahf_setup -saveinstaller option saves the AHF installer locally, making later downgrade operations easier.
  • Component-level event grouping: Insights Timeline can group events by component as well as host, event, and database, while the home dashboard receives performance optimizations.
  • System Health Monitor integration: SHM is integrated and enabled by default for single-instance, non-GI systems. It monitors OS processes, memory, network, I/O, and disks; its data is included in AHF collections and Insights.
  • New Exachk best-practice checks: Exachk adds critical-issue checks EX88 and DB53.
