To improve Blockset elapsed time, and disk and tape utilization, specify installation option SDB=LARGE as your site's installation (SDB=INPUT is the IBM-supplied default). SDB=LARGE allows DFSORT to select the system-determined optimum block size for your disk and tape output data sets, when appropriate. |
