The Rule of Thumb (R.O.T.[ten]) method ... 1) Size it for UDB 2) Go to TCP.org and - find a benchmark using UDB - find the same (or very similar benchmark) using Oracle 3) Document the assumption of linear scalability 4) Use ratio of UDB benchmark to Oracle benchmark sizing, brushed against your UDB sizing, as the basis for Oracle sizing. The correct way, of course, is to actually fire up the application under Oracle using vendor-supplied hardware and do your own benchmark of the target configuration under target load. -- Hans Forbrich (mailto: Fuzzy.GreyBeard_at_gmail.com) *** Feel free to correct me when I'm wrong! *** Top posting [replies] guarantees I won't respond.
