Batch Stacking and Dynamic Data Set Stacking

Data sets written by the CTTSBD utility are not stacked by the Control-M/Tape Dynamic Dataset Stacking facility. DO STACK, DO STKRULE and DO STKGROUP statements in relevant Control-M/Tape rules are ignored by the CTTSBD utility.

Use the CTTSBD utility to implement data set grouping similar to the grouping produced by DO STKGROUP statements. Also, to force stacking of data sets that are not normally stacked by the Dynamic Dataset Stacking facility.

Batch stacking can be used to complement the Dynamic Dataset Stacking facility in the following way:

• Data sets are normally stacked using the Control-M/Tape Dynamic Dataset Stacking facility at time of creation.
• The CTTSBD utility can be run periodically to consolidate under-utilized volumes and to alter data set placement according to site needs.
