How to Uninstall Oracle TFA (Trace File Analyzer)

Oracle Trace File Analyzer (TFA) is part of Autonomous Health Framework (AHF) and is widely used for collecting diagnostic data in environments. However, in some cases you may want to completely remove TFA from the system.

Check TFA Binary

First, verify whether the TFA binary exists:

root@ORACLEDBASECRETS/#cd $ORACLE_HOME/bin
root@ORACLEDBASECRETS/oracle/app/12102/grid/bin#ls -tlr |grep -i tfa
-rwxr-x--x 1 root  oinstall  1748 Apr 13 2021  tfactl
        

Check if TFA is Running

Check running processes:

root@ORACLEDBASECRETS/oracle/app/12102/grid/bin#ps -efa |grep -i tfa
    root 46137984 50922538   0 02:49:12  pts/1  0:00 grep -i tfa
        

No active TFA process was found, which means TFA is either stopped or not properly configured.

Locate AHF Installation

The AHF installer package was located under:

root@ORACLEDBASECRETS/oracle#cd findb
root@ORACLEDBASECRETS/oracle/findb#ls -trl
total 0
drwxrwxrwx 3 oracle   oinstall  256 Mar 10 22:53 AHF-AIX-PPC64_v21.4.2
root@ORACLEDBASECRETS/oracle/findb#cd AHF-AIX-PPC64_v21.4.2
root@ORACLEDBASECRETS/oracle/findb/AHF-AIX-PPC64_v21.4.2#ls -trl
total 1560016
-rwxrwxrwx 1 oracle   oinstall       1525 Mar 10 22:52 README.txt

-rwxrwxrwx 1 oracle   oinstall        384 Mar 10 22:53 ahf_setup.dat
-rwxrwxrwx 1 oracle   oinstall  798703189 Mar 10 22:53 ahf_setup
drwxrwxrwx 2 oracle   oinstall        256 Mar 10 23:11 oracle.ahf

Stop TFA Service

Before uninstalling, ensure TFA is stopped:

root@ORACLEDBASECRETS/oracle/findb/AHF-AIX-PPC64_v21.4.2#tfactl stop
Stopping TFA
TFA Stopped Successfully
. . .
Successfully stopped TFA..
root@ORACLEDBASECRETS/oracle/findb/AHF-AIX-PPC64_v21.4.2#

Uninstall TFA

Run the uninstall command:

root@ORACLEDBASECRETS/oracle/findb/AHF-AIX-PPC64_v21.4.2#tfactl uninstall
