After uninstall oracle, there is remaining directory. 'tfa' After uninstall ORACLE is complete, I can see 'product' directory is removed and I checked sqlplus is not available anymore. The final message looked fine.

However, there is a remaining or replaced directory, which is named tfa. I've searched it and it is a kind of tool to help us find out what's going on.

My questions are:


Why isn't it uninstalled?
Is it installed automatically at the same time of ORACLE install?
Can I remove it with rm command?
After uninstall, what kind of things do I have to check?


My ORACLE version is 12c.
TFA is a seperate installation. It is not part of the database home. Uninstalling the database home does not automatically uninstall TFA.
It is installed while executing root.sh, but it is a seperate installation.
No. Uninstall it with $ORACLE_BASE/tfa/$(hostname -s)/tfa_home/bin/uninstalltfa.sh, as root user.
None.
