(1) Start of job.
(2) Execute HRUDCRX.
(3) Spool the message dataset.
(4) Define a dataset to store LOG (DCRLOG) to set or release dataset statistics information.
(5) Define the volume serial number of ‘CSAVOL1, CSAVOL2’ in the cache storage system.
(6) Define a dataset to store the device number.
(7) Define an area (VTOC area) to release dataset statistics information.
(8) DDNAME defines the dd name in the DD statement. VTOC specifies the cache residence to be released by
VTOC area. DDNAME defines the dd name in the DD statement. DATASET specifies the residence area to be
released by dataset area (DSN: USER.FILE).
(9) Define an area to release dataset statistics information. VOLUME defines a volume serial number in the cache
storage system. DKU releases all statistics area in the volume serial number of ‘CSVOL3’.
(10) Define an area to release dataset statistics information. VOLUME is a required parameter to define a volume
serial number of ‘CSVOL4’ in the cache storage system. ECCENTRICAREA is a parameter to release only
eccentric areas(s).
(11) End of command.
(12) End of job.
