Introduction:

Oracle Trace File Analyzer (TFA) is a powerful diagnostic tool included with AHF (Autonomous Health Framework). It helps Oracle DBAs and system administrators collect, analyze, and manage diagnostic data for Oracle Database, Grid Infrastructure, and ASM environments — especially during performance or crash issues.

1. Check TFA Status

tfactl status
tfactl start
tfactl stop
