RE: raw versus Mounted File Systems

Mark - Thanks very much. You are right, that Cary guy really nails those performance issues. The original paper date is 1992. I guess that if you say something about Oracle over 10 years ago and it is still relevant, that would have to qualify as a classic.

Dennis,

I think the paper you ae thinking of is "Makingthe decision to use raw devices", and it's MetaLink Doc ID 29676.1. It was written by this guy named Cary Millsap, who seems to think he knows a thing or two about Oracle performance tuning....;-)
