In this release, AHF introduces enhanced functionality for managing and sharing problem summaries. You can now copy the contents of the AHF Problem Summary as plain text, making it easier to share information. Additionally, AHF has been updated to detect and provide resolutions for new problems.

Since version 24.4, AHF has had the capability to detect issues and present a summary along with resolutions (Node Eviction Detection and Resolution). The Problem Summary page is accessible under the Detected Problems panel in Insights.

AHF Insights has introduced enhancements to both the Timeline and Operating System (OS) Issues sections, offering more detailed analysis and improved usability.

The Data Guard section has undergone a significant transformation to enhance your experience, making it smoother, faster, and more insightful.

• Sleek New Design: Data Guard is now seamlessly integrated into the Insights report, providing one-click access to your environments. No more searching—just instant access to the information you need. The UI/UX of the Data Guard section has been completely overhauled, offering a more intuitive and user-friendly design.
• Introducing the New Data Configuration Page: New features like Switchover Readiness and Failover Readiness computed values have been introduced, eliminating the need for manual calculations and saving you time.
• Database Symmetry Information at Your Fingertips: When you drill down into a database, you’ll now see a summary of Database Symmetry information. This feature aligns with the Standard Oracle Recommendation, making it easier than ever to ensure symmetry and keep you ahead of the curve.
• All-New Database Wait Events Table: A comprehensive table of Wait Events Records has been added to the drill-down view, helping you quickly identify and address potential bottlenecks, which is crucial for understanding your database’s performance.
• Centralized Database Details: All the essential database details, such as Configuration Details, Configuration Changes, and Properties Changes, are now consolidated into a new page: Additional Details. Everything you need is neatly organized in one place.

With this update, you can now access contextual performance reports like Automatic Workload Repository (AWR) Reports, AWR Compare Reports, and Perfhub Reports directly from the Insights report. These reports help identify issues related to workload, SQLs, and other performance areas, providing a more comprehensive analysis.

In previous versions, these details were not available in the Insights report. Now, users can easily open the "Additional Reports" section from the Insights Report and correlate AHF Insights' findings with the information in these additional reports.

The "Additional Reports" section currently supports:

• AWR Reports
• AWR Compare Reports
• Perfhub Reports

How to Generate and Access Insights Reports:

1. Use the command: ahf analysis create --type insights to generate the Insights report.
2. Copy the generated Insights zip file to a system with browser support.
3. Extract the zip file.
4. Open index.html.
5. Click on the "Additional Reports" section to view the reports.

The AHF Insights interface has been upgraded from the Model-View-ViewModel (MVVM) architecture to a Virtual DOM architecture, with Oracle JET being updated to version 16.0.1.

AHF Balance now provides enhanced recommendations for Database Resource Manager settings to minimize noisy neighbor issues, especially in disaster scenarios.

AHF Balance recommends CPU_COUNT settings based on the last month's CPU usage history. In the case of Disaster Recovery Standby databases, the recorded CPU usage is typically low. However, if a Disaster Recovery Standby becomes a Primary database during a disaster, its CPU usage would significantly increase. Without considering this possibility, the recommended CPU_COUNT might be insufficient to handle the Primary load.

AHF Balance now factors in Disaster Recovery configurations to estimate what the CPU usage would have been if a disaster had occurred at the beginning of the data collection period and persisted throughout. These estimates allow for more accurate CPU_COUNT recommendations that account for both normal operations and potential disaster conditions.
