I’ll be highlighting OpenWorld 2008 presentations that cover some of the most popular E-Business Suite technology stack topics.  A catalog of all of the Applications Technology track sessions with links to the presentations is available here:

One of the most-popular sessions at OpenWorld every year is our discussion about Oracle’s own E-Business Suite implementation. Donna Buhlig and Nigel Cooper, from our Applications IT (AIT) group, have expanded upon previous years’ presentations with a
bigger and more in-depth look at our internal Global Single Instance deployment:
