Advantage:increasing sort area size decreases the I/O, hence quicker sorting
process.
Disadvantage: increasing sort area causes sort process to allocate more
memory, which effects the OS memory allocation
resulting in paging and swapping.
large sort area sizes can used if you are using with a minimal
sort_area_retained_size parameter.

To: Multiple recipients of list 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
