DSPSIZE z/OS DFSORT Application Programming Guide SC23-6878-00 |
|
Performance can be improved for sort applications that use the Blockset technique by using dataspace sorting. The DSPSIZE parameter sets the maximum size of a data space to be used during a run. Specifying DSPSIZE=MAX allows DFSORT to optimize the maximum size of a data space to be used during a run, subject to other system and concurrent Hipersorting, memory object sorting and dataspace sorting activity throughout the run. Total dataspace sorting activity on a system can be further limited by the EXPMAX, EXPOLD, and EXPRES installation options. See the description of DSPSIZE in OPTION control statement for more information. |
