7.25.2.1 System File Sizes

AUTOGEN sets the following files at sizes appropriate for your system:

[SYSEXE]SYSDUMP.DMP

[SYSEXE]PAGEFILE.SYS

[SYSEXE]SWAPFILE.SYS

If you have special workloads or configurations, you can specify different sizes for these files by
performing the following steps:

1.

Log in to the SYSTEM account.

2.

Enter the following command:

$ @SYS$UPDATE:AUTOGEN SAVPARAMS TESTFILES

3.

If the file sizes displayed need to be adjusted, add symbols to the MODPARAMS.DAT file
(described in detail in the HP OpenVMS System Manager's Manual, Volume 2: Tuning,
Monitoring, and Complex Systems
), and repeat step 2 until you are satisfied with the file sizes.

4.

When you are satisfied with the file sizes, enter the following command to ensure that the
modified system files are installed when the system is rebooted:

$ @SYS$UPDATE:AUTOGEN GENPARAMS SETPARAMS

7.25.2.2 OpenVMS Cluster Parameters

If you are upgrading an OpenVMS Cluster system, note the following:

The upgrade procedure creates a new MODPARAMS.DAT for each system root on your
system disk. Normally, there is one root for each computer that boots from the system disk.
You must review and adjust each of these MODPARAMS.DAT files individually.

The MODPARAMS.DAT file for the system on which you are running is located in the
SYS$SYSROOT:[SYSEXE]MODPARAMS.DAT file. The MODPARAMS.DAT files for other
roots on the same system disk can be found in
SYS$SYSDEVICE:[SYSx.SYSEXE]MODPARAMS.DAT, where x represents the root number;
for example, SYS0, SYS1, SYS2, and so forth. (Valid root numbers might include hexadecimal
digits—SYSA, SYSB, and so forth.)

Be sure the EXPECTED_VOTES value is correct. This value is the sum of all votes in the
cluster. For example, if there are five computers in the cluster and each has one vote, the
value is 5.
