Hi,

Could you expalin me about VSCORE parameter for Syncsort?

if i have coded VSCORE=512K on one JCl and omitted VSCORE on other which would be efficiant(In terms of CPU Time and elapsed time)

how to test the performence other than unit testing.

Regards,
Pavan.

Perhaps i am missing something. . .

How does one test one "thing" versus "another" without running the tests. . . icon_confused.gif

Probably by someone else doing the testing and sending him the results? icon_biggrin.gif

I recommend you to get in touch with SyncSort representative at your shop - these values should not be used just by choice, they may have diverse effect if not used carefully.

Hi anuj,

Thanks for the information you are right

The size in our programs was VSCORE=512K but defalut size in our environment is 2M so our performence improvement group has recomended not coding of VSCORE=512K.

Regards,
Pavan
