They even had a copy for the shelf. I'm assuming everyone else has theirs by now and are busily reading. Please post any comments or observations. Leave it to Cary to put exercises at the end of each chapter. A quick flip through makes me want to abandon study for my last OCP exam. Dennis Williams DBA, 80%OCP, 100% DBA Lifetouch, Inc.

HT basically makes your CPU to 2 over 50% slower CPUs, providing that all your virtual CPUs will be loaded and you are using the same types of CPU instructions in all of your processes (I doubt that you are using MMX, SSE or even FPU that much with your Oracle database). Situation gets especially bad with parallel execution where Oracle thinks it has 4 physical processors whilst you actually got 2 for example.
