Measure Reference Manual

cpu ( line-name.subdevice )
cpu is the number of the processor, in the range 0 through 15.
line-name is the name of the line, specified as: { $name7 | $num |
logical-Define-name }.
subdevice is the name of the subdevice, specified as: { #name7 }.

Usage Notes for All PVUs and RVUs
• You can use the LISTACTIVE command to read the active records of DISKFILE entities. When
you use the LISTACTIVE DISKFILE command, the disk file spec must be a valid and unique disk
file name. MEASCOM expands partially specified file names with current SYSTEM and
VOLUME defaults.
• The LISTACTIVE command cannot be used to read DISCOPEN or PROCESSH counters:
The DISCOPEN record is unavailable to the LISTACTIVE command because you have no
way to uniquely determine the Open Control Block (OCB) number of an active file.
MEASCTL needs the OCB to locate the record.
◦
◦ PROCESSH records are unavailable because the complexity of the measurement could
degrade system performance.
If you have specified a collection interval, you can use the LIST command to read DISCOPEN
and PROCESSH counters from a currently active data file. When you use a collection interval,
data is collected in an internal buffer and written to the data file when the buffer is full. One
or more collection intervals might pass before data is written to the file.
• The FILE and PROCESS entities display the names of open files. Because a process can open
resources other than files (such as a process or $0), the reports for these entities sometimes
include file names that are invalid according to Measure syntax. To display such reports,
specify the CPU, PIN, and file number of the resource rather than its file name. See the examples
under LIST entity-type (page 68).
• Information displayed by the LISTACTIVE command can differ from information displayed by
the LIST command:
◦ For a LISTACTIVE command, MEASCOM requests data from the Measure control process
(MEASCTL) in the respective CPU. MEASCTL reads the requested data from the active
counter record in system data space.
◦ For a LIST command, MEASCOM requests data from the Measure file-handling process
(MEASFH) for the respective data file. MEASFH uses information stored in the data file
to determine the activity of the counter during the measurement window (or during the
report window in the LIST command).
Usage Notes for H-Series and J-Series PVUs and RVUs
• In H06.23/J06.12 and later RVUs, the LISTACTIVE DISC command for CLIM-attached disks
supports the partition number as an optional DISC specification parameter. The partition
number is the number assigned to a partition within a partitioned disk. In addition, the partition
number for CLIM-attached disks will be displayed by the LISTACTIVE DISC command if the
