I'd like to take a moment to just declare that Oracle DBAs are insane.

I'm dealing with one of them right now who pushes back against any and all reasonable IT practices, but since the Oracle databases are the crown jewels my boss is afraid to not listen to him.

So even though everything he says is batshit crazy and there is no basis for it I have to hunt for answers.

Our Oracle servers have no monitoring, no threat protection software, no nessus scans (since the DBA is afraid), and aren't even attached to AD because they're afraid something might break.

There are so many audit findings with this stuff. Both me (director of infrastructure) and the CISO are terrified, but the the head oracle DBA who has worked here for 500 years is viewed as this witch doctor who must be listened to at any and all cost.
