b Table 11-1 (Cont.) AUTOGEN Phase Parameters

| Phase Input Files Output Files Function
SETPARAMS  SETPARAMS.DAT VAXVMSSYS PAR Run SYSGEN to set system parameters
AUTOGEN.PAR specified by the SETPARAMS.DAT and to
generate a new AUTOGEN.PAR file.
Ni SHUTDOWN None None Prepare the system to await a manual
reboot.
9 REBOOT None None Automatically reboot the system.

Table 11-2 Execution Types

. Type Meaning
at RE EEA Ve VERE SEVE
INITIAL Specifies that AUTOGEN is being executed as part of an initial

system installation. The SAVPARAMS phase is never executed

in this case.
€ V4UPGRADE | Specifies that AUTOGEN is being executed as part of an upgrade
from a Version 4.n system or that interactive tuning is being
performed. V4UPGRADE is the default execution type.
V3UPGRADE Specifies that AUTOGEN is being executed as part of an upgrade
from a Version 3.n system to a Version 4.n system. ,

The commands and examples in the next sections illustrate AUTOGEN
procedures you would use to adjust a typical Version 4.4 system after an
upgrade.

ša DTTEITJ Collecting Data for AUTOGEN Calculations

To collect the data AUTOGEN needs to perform its calculations, issue the
following command: č

$ OSYS$UPDATE:AUTOGEN SAVPARAMS GETDATA
This command instructs AUTOGEN to

» Create OLDSITE«.DAT files that store system parameter data from the
< current system ke

e Collect system version, identification, and hardware configuration data

« Collect user-specified data, if any, from MODPARAMS.DAT (see
Section 11.4)

« Write data to a PARAMS.DAT file for use in subseguent calculations or
propagation to the new svstem

Example 11-1 shows a typical PARAMS.DAT file. The first group of items
is a list of AUTOGEN's conclusions about the system version, system ID,
and hardware components. (Table 11-3 defines these items.) You should
scrutinize the Boolean items to verify that AUTOGEN has drawn the correct
conclusions about your hardware configuration.
