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...

Subject: Re: Confused on DFSORT SORTWK
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.
