Using HRUDCRT Commands to Display Information at the
Console
HRUDCRT supports the following commands:
• COUNTS displays cache volume or dataset statistics. This command can
also reset the counters if necessary.
• STATUS displays cache status information.
• HELP displays definitions of terms that appear on screen.
Using COUNTS to Display Cache Volume or Dataset Statistics
Figure 4-22 illustrates HRUDCRT COUNTS command parameters.
• VOLUME specifies a process target by volume serial number.
• DKU|DKC specifies a target range. DKU means you specify by a particular
volume parameter, and DKC means you specify all volumes in the same
storage system ID. You must also define the RAIDPARM DD statement.
(DKU is the default value.)
• DSEXTENT|NOEXTENT specifies whether you want statistics by dataset
or volume. (NOEXTENT is default value.) Note: If you specify by
DSEXTENT, do not use the RESET parameter.
• REPORT|NOREPORT specifies whether or not you want a printed report.
(REPORT is default value.)
• RESET|NORESET specifies whether or not you want to reset the cache
statistics information counter to zero. (NORESET is default value.)
