Can data space improve performane in DFSORT of 64 bit z/OS?

Frank Yaeger · Posted: Fri Dec 10, 2004 11:15 am Post subject:

With z/OS DFSORT V1R5 and above, DFSORT will choose whichever among Memory Object sorting, Hipersorting or dataspace sorting will give the best performance. With DFSORT R14 (z/OS DFSORT V1R4 and below), DFSORT will choose whichever among Hipersorting or dataspace sorting will give the best performance.

For more information on how DFSORT can take advantage of 64-bit architecture, see the "Can DFSORT take advantage of 64-bit real architecture? " Ask Professor Sort item at:
