6 Analyze Issue Root Cause
Autonomous Health Framework Scope (AHF Scope) is a standalone, interactive, real-time capable front-end to Cluster Health Advisor (CHA). AHF Scope requires a very small foot-print on the monitored system.
CHA continuously monitors cluster nodes and Oracle RAC databases for performance and availability issue precursors to provide early warning of problems before they become critical.
Note:
GIMR is optionally supported in Oracle Database 19c. However, it's desupported in Oracle Database 23ai. For more information, see Removing Grid Infrastructure Management Repository.- Introduction to AHF Scope
AHF Scope is a standalone, interactive, real-time capable front-end to Oracle Cluster Health Advisor (CHA). AHF Scope requires a very small foot-print on the monitored system. - Cluster View: Connecting and Basics of Monitoring
Start AHF Scope using the scriptahfscope
on Linux/UNIX orahfscope.bat
on Microsoft Windows. This script is located in the/opt/oracle.ahf/ahfscope/bin/
directory. - Expert Mode
Expert mode facilitates an advanced analysis of the metrics and their observed values against the predicted ones. - Live and Passive Sessions
AHF Scope maintains two separate sessions in parallel, Live Session (Primary) to receive current metrics in real-time and Past (Replay) Session to display statically a situation encountered at an earlier time. - ahfscope Console Commands
