the DBA and system administrator may be the same person

The instructions in

this section are directed to the system administrator.

For setting or modifying SYSGEN parameters, OpenVMS provides the AUTOGEN
utility

You can also use SYSGEN, but this is an older utility, and its use is

discouraged, except perhaps for checking current values

You must have SYSPRV

or BYPASS privilege to run these utilities.

AUTOGEN provides a permanent method for setting parameters, and it documents
all changes

AUTOGEN also lets you recalculate any parameters that depend on

other parameters that you might have changed

Remember to record parameter

values before changing them, and determine beforehand what results you expect
from your changes

If the expected changes do not occur, then restore the old

values before trying again.

Run the AUTOGEN utility with the SAVPARAMS parameter by entering the
following command:

$ @SYS$UPDATE:AUTOGEN SAVPARAMS GETDATA

This step saves current parameters to a file named AGEN$FEEDBACK.DAT.

If you have not already done so, then run AUTOGEN GETDATA to ensure that
the file PARAMS.DAT has been generated.

$ @SYS$UPDATE:AUTOGEN GETDATA

Examine the parameter settings in the current PARAMS.DAT, and if they are
inappropriate, then change them in the MODPARAMS.DAT file by using the
format MIN_<parameter>=<value> as in the following commands:

MIN_GBLSECTIONS=3000

MIN_GBLPAGES=300000

The MIN prefix indicates that you are setting a lower limit for the specified
parameter

To use the MIN prefix, identify the current value of the specified

parameter (using SYSGEN) and the amount by which you want to increase the
parameter

The sum of these two values is used for the

MIN_<parameter>

entry.

Run the AUTOGEN utility with the GENPARAMS and REBOOT parameters by
entering the following command:

$ @SYS$UPDATE:AUTOGEN GENPARAMS REBOOT
