We are planning to Upgrade our database to 11g.
Our Middle -tier Techonology is Java 1.4.
We are using Type-4 drivers (Pure Java Impementation) i.e., thin-client where we dont required any oracle Client installed to connect to the Database .
Drivers we use is classes12.jar
All our connectivity is from .xml files.
If we upgrade our db what changes are required at connectivity level? Do we need to make any changes at code level?
