Hi Dapi,

But in 9i where i'm using workarea_size_policy=auto and setting a value of pga_aggregate_target. Then the sort_area_size wont come into picture as the amount of space to be allocated would be controlled by ORACLE automatically depending upon the value of pga_aggregate_target and the amount of memory required for sorting.

Cheers...

PS: Advices are welcome as i'm still testing on these grounds.
