It was the thread in January 12th 2023, with subject "DFSORT maximum input records". The message that kicked it off was:
From: Charles Hardee <[email protected]> Subject: DFSORT maximum input records MIME-Version: 1.0 I am trying to sort roughly 4295217295, records using DFSORT. DFSORT issues a message that I have exceeded the sort input record maximum. It appears that this maximum is 4294967295. The limit imposed is because, apparently, DFSORT is handling "equals" by adding a fullword record number to the sort key. Syncsort MFX also has a 4,294,967,295 record limit when EQUALS is used, *but* it can be raised to 140,737,488,355,327 using the EXTCOUNT parm. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Sri h Kolusu Sent: Monday, August 28, 2023 11:50 AM To: [email protected] Subject: Re: Syncsort > DFsort migration >> I think it was mentioned in this list previously that EQUALS in DFSORT has a >> lower limit on maximum number of records than SYNCSORT. Michael, Can you please provide link to that topic that mentions that DFSORT has a lower limit than the other product? We do have limits and I *believe* it is the same as the other product, but if you are running on Z15 and higher you can use sort accelerator(with OPTION ZSORT) with DFSORT which can sort up to 9,223,372,036,854,775,807 records ( Nine quintillion two hundred twenty-three quadrillion three hundred seventy-two trillion thirty-six billion eight hundred fifty-four million seven hundred seventy-five thousand eight hundred seven) as mentioned here https://www.mail-archive.com/[email protected]/msg124898.html Btw it would a while for any customer to sort that many records.
