Running GPA
GPA does not require installation; it is configured to run from the installation subvolume
$SYSTEM.ZGPA. To run GPA, you simply set your current volume to the location of
your Measure structured data files and invoke GPA’s TACL macro
$SYSTEM.ZGPA.OBEYTUNE. When GPA completes the analysis, it generates the
output reports. You can direct the report to any printer device by suitably modifying the
OBEYTUNE file.
However, if GPA was not preinstalled on the system, it can also be installed to any
$volume.subvol. To run GPA, simply modify the OBEYTUNE to run GPA from the
subvolume where it is installed.
Tuning the System with PUPIN or SCFIN
In this final step of the procedure, you implement some of the GPA tuning
recommendations by running a PUP INPUT file, PUPIN, or an SCF INPUT file, SCFIN,
which GPA generates as part of its analysis. PUPIN/SCFIN contains commands for
redistributing primary disk process paths and resetting disk volume cache allocations. (If
you want to restore the system to its previous condition after you run PUPIN/SCFIN,
you can do so with another PUP or SCF INPUT file, PUPBAK/SCFBAK.) Other GPA
tuning recommendations are discussed in Section 4: Using GPA Information
, under
Implementing GPA Tuning Recommendations.
