I'd be tempted to make it 4 times your largest expected working set, but how you arrive at that figure is beyond me...

What's your experience about the temporary table design? I read Michael Ault's Orcale8 Administartion and Management , it says "For Cost-based optimization, it should be 4 times of the largest table". I have a table of 60 Million records, and it costs 16GB, should I have a 64GB temp tablespace(I don't think so, though it's a 100GB database, and I have a 300GB of diskspace).

Thanks for your advice.
