4-8 Performing Cache Manager Operations
Hitachi Cache Manager User’s Guide
Figure 4-7 is a sample JCL of a COUNTS command for dataset statistics.
Cache Manager edits and prints out dataset statistics information for the
specified datasets, then edits and prints out dataset statistics information for
all volumes with the same storage system ID (SSID).

(1) Start of job.
(2) Execute HRUDCRX.
(3) Spool the message dataset.
(4) Define a dataset to store the device number.
(5) Define a dataset to store the control statements.
(6) Edit statistics information and print out it. VOLUME defines a volume serial number in the cache storage system.
DKU specifies the entire volume. DSEXTENT processes dataset statistics information of specified datasets.
REPORT edits and prints out statistics information.
(7) Edit and print out the statistics information counter. VOLUME defines a volume serial number in the cache
storage system. DKC specifies all volumes with the same storage system ID (SSID). This is necessary to define
the RAIDPARM DD statement. DSEXTENT processes dataset statistics information of the specified datasets.
REPORT edits and prints out statistics information.
(8) End of command.
(9) End of job.
