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.
Caution
Note that any changes in the disk primary CPU invoked by running GPA’s PUPIN or SCFIN
file are not permanent and will not be in effect after a cold load.
