What funny about having an oracle server that continuously runs 500-1000 queries without a skip is the hardware that you need to do it. I can achieve greater than that with mysql on a PENTIUM 2 with 256 megs of ram. It might be a tad slow (actually it isnt, i can vouch), but it still works just as good.
Why buy a Product that
a) Has some of the WORST, least descriptive error messenges EVER
b) Costs thousands of dollars per C P U. (umm why per CPU?)
c) Crashes when running too many malformed SQL queries (10g). You can take out an oracle 10g server running on a pentium 4 3.0 with a gig of ram with 30 people runnign malformed sql. WTF. Dont say "Well you should be running better hardware."
d) Horribly high system requirements
e) On a MASSIVE system manages to keep up with a mysql server running on a pentium 2.
