Hi!
First of course get the company, who sold you your development environment,
basic functionality like bind variables to work.
You could reduce your optimizer_max_permutations (default 8), but be

Hi!
It's generally good idea to review optimizer_index_caching and

performance problem currently, I'd not look at them first.
You can get elaborate information about those if you search for Tim Gorman's

You also might try out first_rows hint instead of rule. Oracle keeps
