PARASORT improves elapsed time performance for sorts whose input is a multi-volume tape data set and/or concatenated tape data sets. Reduced elapsed time can help critical sort applications achieve batch window goals.
The performance improvement from PARASORT is a result of processing the SORTIN input volumes in a parallel fashion. Depending upon the resources provided, elapsed time can be reduced up to 20% for 2-way input and up to 33% for 4-way input.
Although you may need to create special esoteric unit names, PARASORT itself is included with MFX and will be available once MFX is installed. Note that creating PARASORT esoteric unit names need not be done as part of the installation procedure. It can be done at any time.
If you will be using PARASORT, see the instructions for creating PARASORT esoteric unit names in PARASORT.
