Hi all,

Now that we are mentioning names, please look at the following info from Cary Millsap's site - part of the acknowledgements from the 'Why a 99%+ Database Buffer Cache Hit Ratio is Not Ok' paper:

Science World has been made possible by Juan Loaiza at Oracle Corporation, who created the idea to instrument the
Oracle kernel with event-based performance diagnostic data. Anjo Kolk, with his famous "YAPP paper" [Kolk et al.
1999], was the first to write about how to apply those diagnostic data to the task of optimizing an Oracle system. We also owe a debt of thanks to Sameer Patkar and Roderick Mañalac, who encouraged Anjo to write about the subject; and Shari Yamaguchi and Jim Viscusi, who helped him do it. Thanks go to my dear friend Mogens Nørgaard of
Miracle A/S, who to the best of my knowledge was the first man on Earth to force his entire staff to use only the
Oracle wait interface to optimize Oracle systems. Without the insight of these gentlemen, we'd probably all still be spending 70 hours a week using ratio-based checklists to tune our Oracle systems.

In brief: Juan Loaiza started it all, Anjo Kolk wrote about it with help from others, Mogens Nørgaard implemented it.
