Oracle RAC enables the Oracle Database to

run mainstream business applications of all

kinds on clusters including popular

packaged products (such as Oracle

Applications, Peoplesoft, SAP), in-house

developed applications, which can be either

OLTP, DSS, or a mixed workload.

"We're pushing out over a mil lion page views

on our Web site, and each one is dynamic,

hosted up by hits to our database. We required

something that could manage this with ease

and the highest possible availability, so we

chose Oracle Database with Real Application

Clusters." Shawn Kernes, Vice President of

Technology StubHub
