Hi,
Setting the sort_area_size to something so big it sounds silly may actually
improve some querries dramatically. I don't see why it should degrade
performance if you have the physical memory to spare.
We had a batch job that took about 60 hours but had to be tuned so it
fitted in the 4 hours maintenance window. Apart from some funky compute
statistics we increased the sort_area_size to 100Mb after which it did a
hash join i.s.o nested loops and finished well within half hour

Please respond
to ORACLE-L
we had a customer of the sort_area_size=10000000
in their database, the temp table space is 256MB, the
db_block_size is 8k. They have some performance
problem, I think it's probably related to the setting
of sort_area_size(we have only one user). So what's
the benefits/disadvantage of too big sort_area_size?
Thanks,
Chris
