Automatic script to change PI in case of high Skew - response (1) by dnoeth

Hi Saran, 
i doubt a script like that exists. Choosing a PI without knowledge about the data plus join and access paths will not automatically result in better performance.
You should start doing it manually with the largest skewed tables first.
Btw, what's your definition of "skewed", > 40% is a quite large number.
