You can try to ICEGENER whole input to DD DUMMY. It will take some time, but you will get exact number of records and bytes.
Then you'll be able to help DFSORT by using FILSZ with correct size.

Regarding SORTLIB DD - do you need it in *any* sort job, or just this one?
How the DFSORT was installed? Was it part of ServerPac?
BTW: I just read in documentation that SORTLIB is required when sortworks on tape are used.

In one failing job, we get

ICE046A E SORT CAPACITY EXCEEDED - RECORD COUNT 41,235,203
ICE046A E SORT CAPACITY EXCEEDED - RECORD COUNT 41,235,203
ICE253I 0 RECORDS SORTED - PROCESSED: 41,235,203, EXPECTED: 310,580,760  <== 
note very high expectation

As to how much DASD space is available, I have no idea. Not a storage guy.
Virtual memory is whatever it is at z/OS 2.1.
User tried tape sort but had the job cancelled after 24 hours. Unfortunately 
canceler apparently purged job as well, so nothing to look at.
As for why specify SORTLIB DD: DFSORT requires it. Job will not run without it.

Let me ask again:
What is the size of input data?
How much space do you have for temp datasets?
How much memory can the job use?


BTW: While sortworks on tape can be justified in case of lack of DASD space, I 
still see no reason to specify SORTLIB DD.

Let me reiterate. The problem job tries to allocate more DASD work space than 
*exists* on the system. SORTIN is on tape--multiple files. We have the 
capability of putting more volumes online temporarily, but this is a major PITA 
and requires intervention from the Storage boys. I'm hoping that tape SORTWK 
will get the user over the occasional hump for this ad hoc non-production job. 
It does not have to perform well. It just has to work.

Get rid of SORTLIB DD
Get rid of SORTWKnn DD
Use dynamic sortwork datasets, optionally set the number of datasets via OPTION 
DYNALLOC Don't use tapes for sortwork

BTW:
What is a size of input data?
How much space do you have for temp datasets?
How much memory can the job use?
