private sort VS shared sort

cat
Hi Folks,

Quick question, what is exactly the difference between private and
shared sort.From IBM doc, I know if intra-partition parallelism is
disabled, DB2 can only use private sort. If intra-partition
parallelism is enable, DB2 can choose between private and shared sorts
to determin which will be more efficient. ( Using different memory
area to perform the sort). So according to this, anyone can let me
know the exactly concept of the two different sorts. And more
important, how can you find out which sort method db2 pick to use for
the current application.

I will really appreciate any reply. Thanks

Cat
