Dear

I have a sort program running ok under zos v1r9, but after upgrade to zos v1r10 last weekend, job completes with CC=00, but the sortout data is invalid ,where they want to insert '00', the SORT select is now adding D. hex 'C409' instead of hex 'F0F0'.

It's a very simple sort. But many records. 1900 tracks on input.
this is what happens, see colum 74 75. should be '00', but now with a 'D.' in it.
- ----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8

616320000521 0CD.rr?A5190233519 101 369597363361....°.. D.1516

the normal situation should be
- ----+----1----+----2----+----3----+----4----+----5----+----6----+----7----+----8
********************************* Top of Data **********************************

616320000521 0CD.rr?A5190233519 101 369597363361....°.. 001516

I also noticed that, when the job was running ok under zos v1r9, it used hiperspace sorting, but after zos v1r10, it used memory object for sorting, if I tried to turn off the memory object by "mosize=0" , then the job works. I can understand DFSORT evaluates many factors as part of its decision on whether to use memory object, Hiperspace, Data space, etc ... however , how can explain my situation why the sort program was not working with memory object sorting?

(ps: I have applied the ptf UK46178 on this system)

Here are two sort output for your reference ...

This sounds like the problem fixed by z/OS DFSORT V1R10 APAR PK89295/PTF UK47759.

If you can't apply that PTF immediately, you should be able to bypass the problem using MOSIZE=0 (to turn off Memory Object Sorting).

Dear Frank

Very thanks for ur promptly reply , I will arrange to apply that PTF immed.
