Retention

When an output data set is written by the CTTSBD utility, it is subjected to Control-M/Tape rules for retention. When the data set is successfully copied, retention of the input and/or output data sets can be modified according to the setting of the parameters INRET, OUTRET and OUTCAT.

BMC recommends that you run the CTTRTM utility after running the CTTSBD utility to scratch newly freed volumes.

Note: If data sets with CYCLE type retention are to be handled by the CTTSBD utility, a specific number must be specified for the INRET and OUTRET utility parameters. If a data set with CYCLE type retention is detected and no specific value was specified for at least one of these parameters, the data set is ignored (skipped) and the utility continues to process the next data set in the current input volume chain.
