RE: Changing Oracle gid and uid?

Except of course, for root. Chown by root does not touch suid/sgid bits. But then, if you already have root, system security is not an issue.

  But in practice, chown removes the setuid bit. If not, you could break into systems that way. Make a copy of ksh or sh, set the setuid bit and then change ownership to any other user and then execute the new shell with setuid ;)
