    Performance : Optimizer behaviour after upgrading from 9i

    928970
      Hello - We are planning to upgrade from 9i to 11g, Is there somewhere documented how the optimizer behaves and also any code changes that we can recommend to be changed for developers. It would be great for any suggestions.

      Thanks
