I think pga_aggregate_target affects only memory allocation not = temporary space usage.
It might affect the frequency and the sizing of temp allocations but I = think the total usage will be the same.

This is based on the assumption that total sort/hash/whatever space = required to get the task done is higher than the allowed total memory = allocation.

Subject: pga_aggregate_target

I have alot of batch loading processes that run over night. A few them = use 2GB or more of sort space in my temp tablespace. I know I can = increase my pga_aggregate_target dynamically, however, I believe I read = that oracle only allows 1 process to use up to 5% of the = pga_aggregate_Target.

anyway to flex this up? I just need the extra sort space for a few = operations at certain times.=20
