Phase Description
SAVPARAMS Saves dynamic feedback from the running system.
GETDATA Collects all data to be used in AUTOGEN
calculations.
GENPARAMS Generates new system parameters; creates the
installed image list.
TESTFILES Displays the system page, swap, and dump file
sizes calculated by AUTOGEN (cannot be used as a
start phase).
GENFILES Generates new system page, swap, and dump files if
appropriate (cannot be used as a start phase).
SETPARAMS Runs SYSMAN to set the new system parameters in
the default parameter file, saves the original
parameters, and generates a new parameter file,
AUTOGEN.PAR.
SHUTDOWN Prepares the system to await a manual reboot.
REBOOT Automatically shuts down and reboots the system.
HELP Displays help information to the screen.
1 – SAVPARAMS
The SAVPARAMS phase records feedback in the file
AGEN$FEEDBACK.DAT, which can be used in subsequent AUTOGEN
phases. If you specify NOFEEDBACK as the execution-mode
parameter, the information collected is not used.
The SAVPARAMS phase is valid as a start phase and end phase.
SAVPARAMS requires the SYSPRV and CMKRNL privileges.
NOTE
You can specify the SAVE_FEEDBACK option during an
interactive orderly shutdown with SYS$SYSTEM:SHUTDOWN.COM.
Entering this option in response to the prompt "Shutdown
options:" records feedback collected since the system was
last booted. Using the SAVE_FEEDBACK option creates a new
version of SYS$SYSTEM:AGEN$FEEDBACK.DAT. Run AUTOGEN from
the GETDATA phase after the system reboots to use this new
version of the feedback.
2 – GETDATA
The GETDATA phase collects the following information required for
AUTOGEN calculations and places it in the file PARAMS.DAT:
o Hardware configuration data
o VSI-supplied data from CLU$PARAMS.DAT
o Feedback from AGEN$FEEDBACK.DAT (if run in feedback mode)
o User-supplied data from MODPARAMS.DAT
The GETDATA phase also attempts to configure devices on the
system, by executing the following procedure and command:
o The command procedure SYS$MANAGER:SYCONFIG.COM. (For more
information about this procedure, refer to the chapter on
managing devices in the VSI OpenVMS System Manager's Manual.)
o The SYSGEN command AUTOCONFIGURE ALL (unless the symbol
STARTUP$AUTOCONFIGURE_ALL is set to 0 in SYCONFIG.COM).
The GETDATA phase is valid as a start phase and an end phase.
GETDATA requires the SYSPRV and CMKRNL privileges.
3 – GENPARAMS
In the GENPARAMS phase, AUTOGEN calculates the parameter values
based on data stored in PARAMS.DAT and produces SETPARAMS.DAT as
output. AUTOGEN checks to see if feedback is included, and if so,
uses it in the calculations unless the NOFEEDBACK execution mode
was specified when AUTOGEN was invoked. Also during this phase,
AUTOGEN generates the known image file list (VMSIMAGES.DAT).
The GENPARAMS phase is valid as a start phase and an end phase.
GENPARAMS requires the SYSPRV and OPER privileges.
4 – TESTFILES
The TESTFILES phase displays system page, swap, and dump file
sizes calculated by AUTOGEN. (This phase does not change the file
sizes.)
File sizes for all currently installed primary and secondary
page and swap files are displayed. The information is directed to
SYS$OUTPUT and the AGEN$PARAMS.REPORT file by default.
Specify the TESTFILES phase to display AUTOGEN's file size
calculations; to generate new sized files, specify the GENFILES
phase. You cannot specify both of these phases when invoking
AUTOGEN. VSI recommends that you use TESTFILES to display the
file size changes before actually generating new sized files on
your system.
The TESTFILES phase is valid only as an end phase. TESTFILES
requires the SYSPRV privilege.
5 – GENFILES
The GENFILES phase generates the new page, swap, and dump
files on the system. This phase changes the file sizes based
on AUTOGEN's calculations.
The GENFILES phase does not modify a file if the calculated
size change is within ten percent of the existing file size.
The following files are affected: PAGEFILE.SYS, SWAPFILE.SYS,
SYSDUMP.DMP, and all other currently installed page and swap
files. For more information, refer to the chapter on managing
page, swap and dump files in the VSI OpenVMS System Manager's Manual.
GENFILES is valid only as an end phase. GENFILES requires the
SYSPRV privilege.
6 – SETPARAMS
The SETPARAMS phase uses as its input the SETPARAMS.DAT file
created during the GENPARAMS phase. In this phase, AUTOGEN runs
SYSMAN to update the system parameter values in the default
parameter file.
On VAX systems, the default parameter file is
SYS$SYSTEM:VAXVMSSYS.PAR. AUTOGEN saves the current system
parameters in the file SYS$SYSTEM:VAXVMSSYS.OLD before updating
these parameters in SYS$SYSTEM:VAXVMSSYS.PAR. The new values are
also saved in SYS$SYSTEM:AUTOGEN.PAR.
On Alpha systems, SYS$SYSTEM:ALPHAVMSSYS.PAR is the default
parameter file. AUTOGEN saves the current system parameters
in the file SYS$SYSTEM:ALPHAVMSSYS.OLD before updating these
parameters in SYS$SYSTEM:ALPHAVMSSYS.PAR. The new values are also
saved in SYS$SYSTEM:AUTOGEN.PAR.
On I64 systems, SYS$SYSTEM:IA64VMSSYS.PAR is the default
parameter file. AUTOGEN saves the current system parameters
in the file SYS$SYSTEM:IA64VMSSYS.OLD before updating these
parameters in SYS$SYSTEM:IA64VMSSYS.PAR. The new values are
also saved in SYS$SYSTEM:AUTOGEN.PAR.
The SETPARAMS phase is valid as a start phase and an end phase.
SETPARAMS requires the SYSPRV and OPER privileges.
7 – SHUTDOWN
SHUTDOWN shuts down the system and awaits a manual reboot. To
use the new system parameter values generated in the SETPARAMS
phase, specify either SHUTDOWN or REBOOT as the end phase. You
can define the logical name AGEN$SHUTDOWN_TIME (using the DCL
command DEFINE) to specify the number of minutes before shutdown
occurs.
SHUTDOWN requires the SETPRV privilege.
8 – REBOOT
REBOOT automatically shuts down and reboots the system, thus
installing the new parameter values. To install the new system
parameter values generated in the SETPARAMS phase, specify either
SHUTDOWN or REBOOT as the end phase. You can define the logical
name AGEN$SHUTDOWN_TIME (using the DCL command DEFINE) to specify
the number of minutes before shutdown occurs.
REBOOT requires the SETPRV privilege.
9 – HELP
HELP displays help information about AUTOGEN to the screen.
The HELP phase is only valid as the start phase command line
parameter. When you specify HELP for the start phase, the end
phase and execution mode parameters are ignored.
