Take a look at "Changing the Installation Defaults" chapter in DFSORT Installation and Customization (SC26-7524). I believe around z/OS 1.10 defaults became maintainable via PARMLIB. Update member then S ICEOPT,ICEPRM=XX accordingly. Otherwise go the usermod route.

Ervin Sent: Friday, July 18, 2014 11:47 AM To: [email protected] Subject: DFSORT Performance Two simple DFSORT jobs (one COPY and one SORT). One calls the COPY function using an INCLUDE which eliminates all the records. The second calls the SORT function with the same INCLUDE eliminating all the records so the final SORT is never executed. The OPTION COPY does the same number of EXCPS but uses ½ the CPU and does larger I/Os (3-4 times as large) as the SORT. It also runs 4 times as fast as the SORT. The problem with slow SORT appears to be related to the small number of buffers used for the SORT function versus the OPTION COPY. How do we allocate more buffers or storage for the SORTIN file? Thanks, OPTION COPY INCLUDE COND=(26,6,CH,EQ,C'NEVERF') And INCLUDE COND=(26,6,CH,EQ,C'NEVERF') SORT FIELDS=(22,4,CH,A) Neil E.
