whole and also separately analyzes each subsystem with respect to a number of
relevant performance parameters such as CPU utilization, disk volume queuing, cache
hit percentage, and so on. The module processes the formatted data files in
accordance with the model and uses the text formats contained in the TUNEDATA file
to generate the GPA standard textual reports. (Note: GPAG is used on G versions of
Guardian OS, and GPAH is used on H & J versions of Guardian OS.)
PUPIN is a PUP INPUT file that can be run to tune the system according to some of the
GPA recommendations. The file contains PUP PRIMARY and PUP SETCACHE
commands. The PRIMARY commands are used to move primary disk processes
among the CPUs in the system in order to help balance the load on the CPUs. The
SETCACHE commands are used to redistribute the cache allocations for the volumes
to improve the operating efficiency of the system.
PUPBAK is a PUP INPUT file that can be run after PUPIN, if necessary, to restore the
system to its original measured state.
SCFIN and SCFBAK have the same function as PUPIN and PUPBAK, but the PUP utility is
used on systems prior to G02. SCF is used on G02 and later operating systems. Either
PUP files or SCF files will be created, depending on the operating system.
