Measure Reference Manual

STATUS MEASSUBSYS
The STATUS MEASSUBSYS command displays the following status information:
• The number of active or configured measurements and a list of the measurement-data file
names
• The number of active MEASCTL processes and a list of the CPUs where they are active
• In Measure G09 and later PVUs, the current setting of several subsystem environmental settings
such as the number of CIDs supported, CID table locking, and the current default setting for
OSS journal segment construction
• In Measure G11 and later PVUs, the current setting for SQL journal segment construction (ON
or OFF)
Syntax
STATUS [ / OUT filename / ] [ MEASSUBSYS ]
OUT filename
directs command output to filename. If filename does not exist, MEASCOM creates an
EDIT file by that name and writes command output to it. If filename does exist, MEASCOM
opens the file and appends command output to it.
Following execution of the STATUS MEASSUBSYS command, MEASCOM redirects its output
to the current OUT file (typically, the terminal).
The OUT option does not affect the contents of the log file.
MEASSUBSYS
is optional if you specified it as the default command object by using the ASSUME command.
Usage Note
CID stands for counter identifier. For each counter record in a processor—a counter record
corresponds to a measured entity, such as a file or a process—Measure allocates and tracks the
counter record through a CID. The number of CIDs supported in a processor is limited. This limit
can be specified at START MEASSUBSYS time to be 32,000, 64,000, 96,000, 128,000, 192,000,
256,000, 512,000, or 1,024,000 for each CPU. (Values of 192,000 and 256,000 are valid
only in H-series and J-series RVUs, the value of 512,000 is valid only for Measure H04/J02 and
later PVUs, and the value of 1,024,000 is valid only for H06.25/J06.14 and later RVUs.) The
CID value reported is the CID table size. The current number of CIDs in use is reported in the CPU
entity report of each processor.
Examples
• In Measure H06.25/J06.14 and later RVUs, a new CID table size of 1,024,000 is supported
in the display:
+ STATUS MEASSUBSYS
Number of Active (or Configured) Measurements = 0
Number of Active MEASCTL Processes = 4
in CPU(s): 0, 1, 2, 3
Number of Active MEASIP Processes = 8
in CPU(s): 0, 1, 2, 3
OSS OFF, SQL OFF, Skew copy time OFF, Lock CID table ON,
CIDs = 1024K/CPU
• In Measure J01 and later PVUs, a MEASIP process is active on each IPU. This change is
reflected in the total number of running MEASIP processes:
+ STATUS MEASSUBSYS
Number of Active (or Configured) Measurements = 0
Number of Active MEASCTL Processes = 4
STATUS MEASSUBSYS 127
