I have been load testing my companies application on SQL for the past 2 years and have a firm grasp of what is going on there.

My trouble is this, I am now testing the same app on Oracle and will soon be testing on Sybase.

Is there a way to do an apples to apples comparison to the available counters themselves? In other words, if I am looking at the Cache Hit Ratio in SQL, what would I look at in ORA? Does anyone know of a cross reference like this?
