Figure 1. HBSI Format
HBSI turns on hiperbatch processing for SORTIN data sets. To benefit from hiperbatch processing, the SORTIN data set should already reside in hiperbatch. Although hiperbatch does provide significant improvements in elapsed time, it causes some degree of degradation in other system resources. If you use HBSI and the SORTIN data set does not reside in hiperbatch, you may experience some system degradation while not realizing any of the benefits that accompany hiperbatch processing.
