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)
NB! I am running one more Advanced Oracle Troubleshooting training in 2018! You can attend the live online training and can download personal video recordings too. The Part 1 starts on 29th January 2018 - sign up here!
