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.
