As I think someone else noted, Heisenberg's uncertainty principle related to the location of quantum particles at a specific point in time. Your participant was thinking of Schroedinger's cat. Anyway, his point is correct to a certain extent. You need to choose monitoring tools that will have minimal effect on the system being monitored. Oracle has a fairly extensive suite of tools for monitoring performance included in the software from about 8i on up, and they are pretty good about keeping the impact small.

Subject: Heisenberg and measurement intrusion....

I'm on an Oracle performance project and a project participant made a statement regarding measurement intrusion.

Is the statement below accurate?
"So the Heisenberg uncertainty principle mandates we run without monitoring
as a baseline."

I responded with a wikipedia link which I'll send later, but I'd like to get
opinions first. :)

Ted
