Hi
I am trying to decrypt a column which has millions of row, this process takes ages using

ALTER TABLE NPP.TRANSACTION MODIFY (CARD_NUMBER DECRYPT) ;

and uses a lot of undo, anyone got any ideas how i can speed this up , or do i just except that it is IO intensive and will just take some time

I know i cant use nologging and parallel


Thanks
mike
