And i'll post back some information if I can understand them :). Christophe. Thanks Kyle, I’ll send them an Email to see if they have investigated those figures in the parallel scenario..

Good questions on the parallel query statistics. Unfortunately I haven't spent any time looking at extended row source statistics with parallel query. People that come to mind that might know would be Greg Rahn or Christian Antognini. If you find the info, let me know so I can link it into this post! - Kyle Hi Jean-Christophe,
thanks for stopping by.

It was hard for me to get what is estimated and real. When doing parallel processing, How are evaluated the memory and Temp usage figures, are they Max(value per slave) or Sum(value per slave) ? I am working on a Parallel query doing a lot of sorting and I try to figure out what would be the optimal PGA settings to improve the sorts. Thanks again for this nice colorfull article :) Hello Kyle,

Really nice article. It was hard for me to get what is estimated and real.

When doing parallel processing, How are evaluated the memory and Temp usage figures, are they Max(value per slave) or Sum(value per slave) ?

I am working on a Parallel query doing a lot of sorting and I try to figure out what would be the optimal PGA settings to improve the sorts.

Thanks again for this nice colorfull article :)
