Measure Reference Manual

G-series version of MEASFH on the system where you ran MEASFT, using the MEASFH parameter
to specify the object file.
For information about the MEASFT utility, see Appendix D: Measure Data File Tool (MEASFT)
(page 550).
Usage Notes for G-Series PVUs and RVUs
• Prior to Measure G05, a limit of 127.5 MB existed on the size of the measurement data file
that could be opened for analysis. With Measure G05 and later PVUs, the Measure data file
size is 890 MB. However, to create data files larger than the default size of 127.5 MB, you
must allocate the data file prior to measurement. You might also need to adjust the extent size
or max extents values for the data file.
Prior to starting MEASCOM for analysis of large data files, check for sufficient disk space (for
example, twice the size of the data file) to accommodate swap files. Do not use $SYSTEM for
disk swap space. Swapping might interfere with system performance and memory availability
to other applications. If insufficient swap space exists on the $VOLUME where MEASCOM
was started, the MEASCOM segment (SEGMENT_allocate error 21) might overflow and cause
a trap.
• On systems running G-series RVUs, some data files are smaller than the files for comparable
measurements on systems running D-series RVUs due to a change in how MEASCTL writes
data records when there is a collection interval. The difference is most noticeable in large
measurements, especially those that measure all FILE and DISCOPEN entities.
Examples
• To make two measurement data files accessible to MEASCOM (the data file
$DATA.MEAS.MAY04 is the current data file):
+ ADD MEASUREMENT $DATA.MEAS.MAY03
+ ADD MEASUREMENT $DATA.MEAS.MAY04
If you subsequently type this command, MAY03 becomes the current data file:
+ ADD MEASUREMENT $DATA.MEAS.MAY03
• To specify a remote measurement data file as the current data file:
+ ADD MEASUREMENT \NY.$METS.MEAS.MAY06, &
& MEASFH \NY.$SYSTEM.SYS14.MEASFH
ADD PLOT
The ADD PLOT command adds a counter to the current plot definition.
If you already started a plot definition, adding a counter from a second data file causes MEASCOM
to display a warning message, delete the current plot definition, then start a new plot definition
for the new data file.
Syntax
For all entity types except PROCESSH and USERDEF, the syntax is:
ADD [ PLOT ] counter [ ( record-number ) ]
PLOT
is optional if you specified PLOT as the default command object by using the ASSUME command.
counter
is a counter name chosen from the last report generated by the LIST command. If the report
displayed multiple entities, ADD PLOT adds the specified counter from each entity to the plot
definition. You can plot as many as 26 counters in one plot.
