4.11 Running AUTOGEN
values that match your system workload, you can run AUTOGEN in
feedback mode a number of times. For more information, refer to the
upgrade and installation supplement for your computer.
3. Compaq recommends that you run AUTOGEN from SAVPARAMS
through TESTFILES on a weekly basis thereafter, and examine
AGEN$PARAMS.REPORT to determine the need for additional changes.
After you run AUTOGEN following the first 24 hours of system operation (step
1), review the checklist in Section 4.13 to confirm that you have completed all the
tasks described in this chapter.
4.12 Modifying Parameters
When AUTOGEN runs, it uses the parameter values in
SYS$SYSTEM:MODPARAMS.DAT. Based on your examination of
AGEN$PARAMS.REPORT, you might need to modify parameter values in
MODPARAMS.DAT. If so, note that hardcoded values in MODPARAMS.DAT
affect AUTOGEN’s ability to calculate feedback parameters. For AUTOGEN to
properly calculate minimum default values, you should replace the hardcoded
values in MODPARAMS.DAT with MIN_ values. If you need to modify the
parameter values calculated by AUTOGEN, you can use AUTOGEN to change
the hardcoded values in MODPARAMS.DAT.
For more information about the MODPARAMS.DAT file and about using
AUTOGEN in general, refer to the OpenVMS System Manager’s Manual.
