i System Generation

If you are satisfied with the data in PARAMS.DAT, further adjustments are
probably unnecessarv.

If, on the other hand, you need to correct configuration data or modify
system parameters to accommodate special conditions at your site, invoke
AUTOGEN as described in the next section and follow the PRPRAO
outlined in Sections 11.3 and 11.4.

11.2 Invoking AUTOGEN

You can invoke AUTOGEN any time after an installation or an upgrade to
reset parameter values and system file sizes. The new values and file sizes
take effect the next time the system is bootstrapped.

To ensure that you have the reguired privileges, invoke AUTOGEN from the
system manager's account. The format is:

$ 7SYS$UPDATE:AUTOGEN [start-phase) [end-phase] [execution-type]

You can enter up to three parameters to designate the AUTOGEN operation
e you desire. All parameters are optional; however, missing leading parameters
must be replaced by null arguments (that is, "").

Table 11-1 lists the phase parameters and their effects, including the files
needed as input and the files created or changed for output. Table 11-2
summarizes execution types.

Al] files except VMSIMAGES.DAT reside in the directory specified by the
SYS$SYSTEM logical name. VMSIMAGES.DAT resides in SYS$SMANAGER.

The start phase must either precede or be identical to the end phase according
to the seguence shown in Table 11-1 (the end phase defaults to the same
value as the start phase). GENPARAMS is the default start phase; GENFILES
may not be specified as the start phase.

 SAVPARAMS  None OLDSITE".DAT — Save significant old parameters for
propagation and update.

GENPARAMS  PARAMS.DAT : SETPARAMS.DAT Generate new system parameters; create
VMSIMAGES.DAT the installed image list.
TESTFILES PARAMS.DAT SYS$OUTPUT Display the system page, swap, and dump

file sizes calculated by AUTOGEN. (See
Section 11.4 if you wish to specify sizes.)

GENFILES PARAMS.DAT PAGEFILE.SYS Generate new system page, swap, and
SWAPFILE.SYS dump files if appropriate. Cannot be
SYSDUMP.DMP specified as the start phase.
