Hi,

We run Syncsort in our system. W have around 250 jobs that did not have a secondary allocation for Sort Work files.Now we are migrating to DFSORT. Syncsort will dynamically allocate additional work space when not enough space has been allocated in the sort work files. Dfsort does not do this. If no sort works are specified it will do the dynamic allocation. If they are specified it will use the specified amount. So we are getting space abends with DFSORT.

Is there any solution for this?

Thanks,
Selva.

Guessing just a little here, but I'd start by removing SORTWK areas altogether. DFSORT is far more clever than you seem to think!

I would suggest setting the DFSORT installation option DYNAUTO=IGNWKDD. This option tells DFSORT to automatically deallocate any JCL SORTWKs it finds and use dynamic allocation of work data sets instead. Allocating JCL SORTWKs that are too small without specifying secondaries is probably not a great strategy. Allowing DFSORT to allocate the work data sets (along with hiperspace, data space and now memory objects in z/OS DFSORT V1R5) dynamically is a better strategy. Removing the JCL SORTWKs would be the best long term solution, but using DYNAUTO=IGNWKDD will have the same effect without requiring JCL changes. If you specify DYNAUTO=IGNWKDD and need JCL SORTWKs for a specific job, you can use:

Frank, is there an easy way to know if the DYNAUTO=IGNWKDD option is enabled?

superk,

You can run the following JCL and see the installed defaults for DFSORT

Yup, thanks, that did the trick.

Hi,

Can you please let me know what is the equalent option of DYNAUTO=IGNWKDD in syncsort

Thank you
