And if "they" do that, then how in the world do I do maintenance? Not
that "they" can at present. I __am__ "they". That is, I also the main
RACF security person as well as the senior z/OS sysprog. Small shop. In
a different shop, I was more restricted. <shrug>. It just took longer to
get anything done. The security person there acknowledge that she
couldn't verify what I was doing anyway. And knew that if I wanted to, I
could set things up to do literally anything that I wanted and never
even trip an alarm that she would see. But I am relatively trustworthy.
At least when it comes to MY system! Just don't leave the chocolate
unguarded! <grin>.
