GRPLIM keyword

The GRPLIM keyword specifies the maximum number of tasks to be processed in parallel within a group.

If the number of data sets that are registered in the group (CAGRP or DBDSGRP) of DBRC is greater than the value specified for the GRPLIM keyword, IMS HP Image Copy processes the number of subtasks that are specified on the GRPLIM keyword in parallel, and the subtasks that exceed this number are held in a wait state until one of the data set processes ends.

Usage notes
  • If the number of data sets that are registered to CAGRP or DBDSGRP of DBRC is fewer than the value on the GRPLIM keyword, or the GRPLIM keyword is not specified with FUNC=AIC or FUNC=ACIC, IMS HP Image Copy processes all data sets in parallel.
  • This keyword is ignored if it is specified with STACK=ddname, FUNC=IC, or FUNC=CIC.
