I was wrong

Thanks to dear Maria Colgan for her intervention, I am publicly admitting the error of my ways and declaring to never use the drug of the optimizer_index_cost_adj parameter again. I publicly admit (again) that I have (on occasion) used an extremely high OICA setting to try and "force" Exadata to use full table scans over index scans. I was wrong and I am sorry.

Snicker...

I've had a great time at the Enkitec Extreme Exadata Expo (E4) this week in Dallas. I eagerly awaited the presentation of Maria Colgan ("The Optimizer Lady") where she promised to "show through the use of real-world examples what you can do to ensure the Optimizer fully understands the capabilities of the platform it is running on without having to mess with initialization parameters or Optimizer hints."
