The sort in is GDG file in tape, and exists in 6 volumn, so how do I know the number of sortwk and sortout, does the number impact the performance?

How many SORTOUTs would depend on your sort-card and let the sort-product itself pick-up the number of sort-work files required.

Using MAXSORT, the number/size of the SORTWKxx files is dependent on tyour MAXWKSP=xxx PARM to set the amount of data per breakpoint.

Of course, the more you sort per breakpoint, the faster the process overall.

You probably want to send the SOUTOUxx and SORTOUT files back to tape.
