Re: Best utility to max out CPU usage by DB workload in test environment?

Hi Mladen, Thanks for replying.
Goal: It is more academic than something specific tbh. I am trying to understand CPU metrics in various views of Oracle, additionally what wait events prop up in relation to CPU maxing out. I am testing on 19c and planning to run both on-prem and against a couple of cloud vendors' offerings.
