To reject or abend for incorrectly using same dataset for input and output

Have option to control (system level/step control) reject or abend for incorrectly using same dataset for input and output, when no sorting is performend, hence it risk to have inaccurate data. This will avoid developer wrongly coding caused data ...

DFSORT AI Engine

Customer runs lots of DFSORT workload and often has to tune its parameters according to the input file characteristics , amount of memory available and other factors. This can be a cumbersome task, error prone and sometimes cause inefficient use o...

Desired new feature: JOINKEYS on multiple files and new REFORMAT parms

At the moment only 2 files can be joined using DFSORT JOINKEYS. We would like to join records from more files (e.g. 10 files). Subsequently a new 'A' parm of REFORMAT statement should be useful for values that apeer in all files. Kind regards Kons...

zSORT should be able to use Virtual Flash Memory instead of using disk in case of memory shortage

Today, many financial companies use Virtual Flash Memory (VFM) in their zSystems. However, this feature has a limited number of users on z/OS. And there's also TBs of memory on VFM. Why DFSORT or DB2 SORT utilites do not use VFM to improve the per...

IBM zSort accelerator to support removing dublicates

We have enabled the IBM zSort accelerator with succes. But notice that some of our jobs containing sorts, are not elegible.Specifically jobs that sort and remove duplicates. We believe that removing duplicates is a feature that should be possible ...

Allow Sort Work (Temp datasets) to go multi volume

Could you please enhance DFSMS DFSORT to allow work files (Sort work/temporary files) created during SORT processing to go multi volume. Other temporary datasets can now go multi volume apart from SORT work datasets.

Add parm to increase SORTIN and SORTOUT buffers to improve reading and writing throughput

DFSORT's ability to read and write SORTIN and SORTOUT files appears restricted enough to impact the throughput of both Standard files and Striped files. For SORTIN large Striped files can be read 4 times faster by OPTIONs COPY or EASYTRIEVE. CPU u...

DFSort support for non-extended encrypted files

Our company intends to use pervasive encryption to encrypt our mainframe datasets, but DFSort currently does not support non-extended encrypted files. It is crucial that this support is implemented since all our sorting is done through DFSort and ...

DFSORT Y2x fields WTO or SMF field

We need a way to identify all DFSORT job steps using Y2x fields. We want to get away from using 2-digit years and the need to periodically update the Y2PAST/CENTURY/CENTWIN global options. For this we need to take an inventory of what is actually ...
