To remove old oracle home or not
We have all of our DBs on Exadata's in Oracle 19. We used to run Oracle 18 DBs and now have them all upgraded to 19. Our security office keeps flagging it since it is out of date. Being that it is not being used and is just a bunch of binaries is there a security risk involved here by just leaving it? It seems to be the discussion we are having and no one has a technical answer as to whether is or not. If it is a risk what risk is there? Thanks.
