GPA Manual for G-series RVUs

Guardian Performance Analyzer (GPA) Manual – (544977-001) Page 30 of 106
included. For example, to run a detail section for the SYSTEM class and a
summary for each of the others, set the following six PARAMS:
8> PARAM SYSTEM DETAIL
9> PARAM SUBSYSTEM SUMMARY
10> PARAM PATHWAY SUMMARY
11> PARAM SERVER SUMMARY
12> PARAM TRANSIENT SUMMARY
13> PARAM OTHER SUMMARY
The default section-type is DETAIL. To refrain from printing the optional report,
specify:
14> PARAM classname NOPRINT
To suppress printing of the textual report only, enter:
15> PARAM TEXT NOPRINT
9. Run GPA to perform the analysis. Set the volume and subvolume to the location of
your measurement data and enter:
16> RUN $SYSTEM.ZGPA.OBEYTUNE
This assumes GPA has been installed to $SYSTEM.ZGPA. If this is not the case,
substitute the correct $volume.subvolume in the above command line. GPA
processes the data collected by Measure and generates the reports as well as the
PUPIN and PUPBAK or SCFIN and SCFBAK files. You can direct the reports to a
printer device by using the OUT option with the RUN GPA command in the
OBEYTUNE file. The standard and optional reports appear as separate files in the
spooler.
10. To implement the GPA tuning recommendations (primary disk process and cache
block reallocations) in the PUPIN/SCFIN file, enter:
17> PUP /IN PUPIN/
or
17> SCF /IN SCFIN/
11. Use PUPBAK/SCFBAK (if necessary) to restore the system to its previous
condition. Enter:
18> PUP /IN PUPBAK/
or
18> SCF /IN SCFBAK/
12. Perform other GPA tuning recommendations as appropriate (see Section 4 of the
Measure User’s Guide for a general discussion of system tuning).
