I don't have any 3390-9s to work with but, as a scratch estimate, I believe 
they're approx. 3 * 3333 * 15 * 55500 / 1000000000 = 8.3Gb in size.  From the 
message ("ATTEMPTED TO ALLOCATE 80250MB") below, it appears that DFSORT thinks 
it needs 80.3Gb in total.  To me, that means you need at least another 2 mod-9s 
plus DynAlloc=(SysDa,10+) to get it to work.  Even then, you'd be scraping your 
head on the ceiling with the occasional failure when someone else is using just 
a coupla tracks in the pool.

I know that when we're sorting our monthly file of SMF data, I have to resort 
to 80 DD statements of 1000 Cyl spread over a bunch of our SMS pools just to 
gather enough pieces to do the sort.  An' we're a *small* shop.

ps.  I get the daily digest so I'm always behind the times...

I have 8 3390-9 DASD that are strictly for temp space.  99% of the time they 
are completely empty, as was the case when I was running this as there is no 
one else on the system right now.
I'll try using a bigger number.
