Given that you have never tuned a TB+ Oracle database I'm not surprised.

Given that you've never worked with RAC I'm not surprised.
Given that you've never worked with ASM I'm not surprised.
Given that you've never worked with Grid Control I'm not surprised.

Your experience is NOT my experience nor that of the DBAs and SAs I have worked with for more than a decade.
