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... --------> signature = 6 lines follows <-------- Neil Duffee, Joe Sysprog, uOttawa, Ottawa, Ont, Canada telephone:1 613 562 5800 x4585 fax:1 613 562 5161 mailto:NDuffee of uOttawa.ca http:/ /aix1.uOttawa.ca/ ~nduffee "How *do* you plan for something like that?"
