Utility CTDCLHST

This utility erases from the History User Report List file all entries belonging to reports for which the backup period has expired (that is, the number of days that the reports must be retained has passed). The utility produces a list of tapes that can be freed for general use (that is, returned to the free tape pool).

This utility can be run before or after the New Day procedure and it can be run more than once a day (for example, after a computer crash). This utility must be run at least once a week.

For more details, see the INCONTROL for z/OS Utilities Guide.
