| If you invoke AUTOGEN without specifying the execution-mode
parameter (FEEDBACK, NOFEEDBACK, or CHECK_FEEDBACK), AUTOGEN uses
the feedback information in its calculations. However, if the feedback
information reflects system uptime of less than 24 hours, or if
the feedback information is more than 30 days old, AUTOGEN includes
warnings in the AGEN$PARAMS.REPORT file to alert you to potential
problems with the feedback data. If you wrongly assumed the feedback
was valid, the parameter settings might vary significantly from your
expectations. If you specify FEEDBACK (or NOFEEDBACK), AUTOGEN uses (or
does not use) the feedback regardless of the data's reliability.
AUTOGEN proceeds through the SETPARAMS phase (if you specified SETPARAMS,
SHUTDOWN, or REBOOT as the end phase) and sets system parameters
to the values it computed. If you specify CHECK_FEEDBACK, AUTOGEN checks the validity
of the feedback data. If AUTOGEN determines the feedback is suspect,
then AUTOGEN ignores the feedback when computing parameter values.
It will stop at the TESTFILES phase and issue a warning in the report
that parameters have not been changed. You must read the report
and decide whether the calculated values are acceptable. You can
use them (by running the AUTOGEN SETPARAMS phase) or rerun AUTOGEN
with valid feedback data. |
