4-6 Performing Cache Manager Operations
Hitachi Cache Manager User’s Guide
Figure 4-5 is a sample JCL of a COUNTS command for volume statistics.
Cache Manager resets the volume statistics of the current volume, then edits
and prints out the volume statistics for all volumes in the storage system.

(2) //CACHE EXEC PGM=HRUDCRX,REGION=1024K
(3) //SYSPRINT DD SYSOUT=A

(1) Start of job. Execute HRUDCRX.
(2) Spool the message dataset.
(3) Define a dataset to store the device number.
(4) Define a dataset to store the control statements.
(5) Identifies the source of the input statements. An input statement to HRUDCRX is a command. When you code
SYSIN DD*, you identify the statements that follow as input.
(6) Edit and print out volume statistics. VOLUME defines the volume serial number of the cache storage system
(CSVOL1 in this example). DKU specifies the entire volume. REPORT edits and prints out volume statistics
information. RESET resets the volume statistics information counter after the information is printed out.
(7) Edit and print out the volume 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. REPORT is a required parameter to edit and print out the volume statistics
information counter. NORESET defines that the volume statistics information counter will not be reset.
(8) End of command.
(9) End of job.
