[...] while back Greg Rahn at Structured Data blog thought that the best way to get results out of Exadata is by changing your application to get the most out of Exadata. He was very happy to see that [...]

Too true, Paul, too true :)

Not doing something is always faster than doing something. Schema tweaks and the like can result in total elimination of certain code execution and that is always faster than “throwing hardware at it.” Ask me how I know some time, I’ll tell ya! :-)

Thanks for validating that point of view, Greg. The environment we were migrating from was optimized for a 38-node shared nothing configuration and had a bunch of design tradeoff decisions optimized for that kind of a config! It needed some work to make it really sing on Oracle. James Governor’s teasing aside, thank you very much for validating this point of view. :)

The POC I was involved with was of the “apples to apples” variety, which I didn’t think was very fair to Oracle, for the main reason you list, you aren’t truly exploiting the system. It was Database A vs. “Database B” – and that wasn’t even fair.

So much more could have been done and I think many more four letter expletives would have been uttered. ETL would have been different. Security would have been done differently. (I used to have a list of cool things…)

How true – assuming Exadata to be just “another Oracle database” misses out on a lot of potential – Exadata is a balanced configuration, so best results come from using the “whole” of the box and not just a tiny bit. This is one of the key take aways that I will be giving in my OOW talk about an Exadata implementation for e-retail. Here my customer was not only doing stuff faster than before, they were doing things they couldn’t do before!

11 is a great setting to run on !
