Minimising writes to temp is the best optimisation!
Do that by getting accurate estimates in your execution plans wherever possible
and reducing poorly sized work areas -
Trying to avoid multi pass executions - optimise where possible to be one pass
and similarly one pass to be in memory.

Hi,
I am trying to find out what database parameter controls the size of direct
path write temp and is there way to optimize it. You feedback will be
appreciated.
Thank you,
