Automatic TFA Self-Diagnostics on diagcollect Failure

Starting in AHF 26.5, Oracle Trace File Analyzer (TFA) automatically runs tfactl diagnosetfa whenever a tfactl diagcollect operation fails.

This enhancement helps accelerate root-cause analysis and improves support efficiency by proactively collecting relevant diagnostic data without requiring manual intervention.

Cluster-Wide Flood Control for Diagnostic Collection

Starting in AHF 26.5, Oracle Trace File Analyzer (TFA) reduces duplicate diagnostic collections in clustered environments.

During event storms or repeated alerts, TFA minimizes redundant diagnostic bundles across peer nodes, reducing diagnostic overhead and improving event handling. By eliminating unnecessary duplicate collections, this enhancement also helps conserve AHF repository storage and simplifies repository management and review.
