If you’re interested in leading edge database research (as of 2008 :), the VLDB 2008 proceedings are publicly available now.
Here are direct links to some Oracle-specific ones:
- Oracle SecureFiles System
- Optimizer Plan Change Management: Improved Stability and Performance in Oracle 11g
- Closing The Query Processing Loop in Oracle 11g (this one is about adaptive cursor sharing)
