There are so many people here that virtually every demo pod is guaranteed some level of steady traffic, but after a few trips around the floor I can confidently point out a few stand-outs from the attendee-interest perspective:
The audience composition and frequent mentions of this product in keynotes has helped, but there's no denying that people love this thing. (The demogrounds staff was today forced to open a new pod to accommodate the traffic.) If you're not familiar with it, XML Publisher is a Java-based reporting tool (a new addition to the Oracle Fusion Middleware stack in fact) currently supporting E-Business Suite, and soon to support PeopleTools, that separates data from presentation in such a way that users can configure their own Word, PDF, Excel, or HTML reports without IT intervention. Pretty cool.
Oracle HTML DB
Oracle HTML DB has been a star since its introduction in Oracle Database 10g Release 1, and new v2.0 features like a declarative query builder and built-in PL/SQL editor is drawing the attention of developers and "non-developers" alike. Again, lines around the floor for this one.
Oracle Automatic Storage Management
Despite the FUD propagated by storage software vendors as well as "uninformed" sysadmins, the Oracle ASM feature in Oracle Database 10g continues to attract a lot of interest. Sysadmins, tune in! ASM is your friend!
Project Raptor is the long-, long-awaited answer from Oracle to TOAD et al in in re: to a PL/SQL development tool. Wilfred van der Deijl provides a very complete description (as well as screenshots) here; I hope to catch up with product manager Kris Rice about it in a future podcast. Note that the tool will be available for download from OTN shortly.
