Optionally Segregating SMF Data by Day onto a Single Tape Volume

The DAYSTACK feature forces CA SMF Director to request a new tape volume when the end of the day is reached during a dump. The end of the day (and start of the next day) is defined by the SDAY option.

The DAYSTACK feature also determines whether a new dump goes on a new tape or on the same tape used in the previous dump. A new tape is used if the timestamp of the first record in the dump is after the SDAY boundary of the last record on the old tape.
