Facility
The Display/Update SYSPARMS Settings facility provides a full-screen selection list as an alternative to using the SHOW SYSPARMS and SYSPARMS commands for viewing and updating system-wide settings for your NonStop NET/MASTER MS system.
Entering the Display/Update SYSPARMS Settings Facility
Select option S from the System Support Services Primary Menu screen to display the Display/Update SYSPARMS Operands screen, as shown here:
--- Display/Update SYSPARMS Operands --- COMMAND ===>

The Display/Update SYSPARMS Operands screen does not display values for the following system parameters:
CMDAUTH CMDREPL MAPDEL MAPLOAD PPRELOAD PRELOAD PUNLOAD UNLOAD
Issue a SHOW COMMANDS command from the OCS command input line to display the command authority level of commands.
Issue a SHOW PRELOAD command from the OCS command input line to display the value of the CMDREPL, PRELOAD, and UNLOAD system parameters.
Issue a SHOW MAPS command from the OCS command input line to display the value of the MAPDEL and MAPLOAD system parameters.
Issue a SHOW PANELS command from the OCS command input line to display the value of the PPRELOAD and PUNLOAD system parameters.

The Display/Update SYSPARMS Operands Screen
The Display/Update SYSPARMS Operands Screen
The Display/Update SYSPARMS Operands screen includes: A command line
A message line (directly below the command line) A three-column display indicating:
The names of the SYSPARMS operands
The status of any update or reset operations you perform The current values of the SYSPARMS operands
Examining the SYSPARMS Values
You can examine the system parameter values either by scrolling through the display or by searching for a particular SYSPARMS operand. Do one of the following:
Press the F8 (PF08) and F7 (PF07) function keys to scroll forward and backward through the display, respectively.
Enter an L (for locate) command followed by the name of a particular SYSPARMS operand on the command line and press the ENTER key.
Table 5-5 describes how to examine the SYSPARMS values.

For example:
To display the last page of the system parameter values, enter M in the command line and press the F8 (PF08) function key.
To locate the LOGWRAP operand, enter the following command in the command line and press the ENTER key:
L logwrap
The LOGWRAP operand and its value appears at the top of the display area, as shown in the following example:

If the command authority level associated with your user ID is high enough, you can update the values of most system parameters. A few system parameters can be modified only during system startup (before any users are logged on to NonStop NET/MASTER MS).
To update the value of a SYSPARMS operand, position your cursor on the field containing the current value, overtype it with the new value, and press the ENTER key.
If the update is successful, the STATUS field displays an updated message. The update may not be successful due to the following reasons:
If you enter an invalid value, the STATUS field displays an invalid message. A message similar to the following appears in the message line, providing more information about the nature of the invalid value:
CDELAY - THE NUMERIC VALUE '400' WAS OUT OF RANGE, THE RANGE IS 0 TO 300
Resetting a SYSPARMS Operand Value
To clear the invalid status, you can do one of the following: Enter a valid value.
Reset the value (see “Resetting a SYSPARMS Operand Value,” next in this section).
Exit (by pressing the F3/PF03 function key) and then reenter the Display/Update SYSPARMS Settings facility. The old value is retained. If you try to change the value of a system parameter that can only be set during system initialization, an error message is displayed. An example is:
ID - SYSPARMS ID OPERAND NOT VALID AFTER INITIALIZATION COMPLETED
and the STATUS field displays the invalid message.
To clear the invalid status, you must exit (by pressing the F3/PF03 function key), and then reenter the Display/Update SYSPARMS Settings facility.
If your command authority level is not high enough to change the value of a particular operand, an error message is displayed. For example:
CDELAY - INSUFFICIENT COMMAND AUTHORITY LEVEL
and the STATUS field displays the invalid message.
To clear the invalid status, you must exit (by pressing the F3/PF03 function key), and then reenter the Display/Update SYSPARMS Settings facility.
Note You cannot use the scroll function keys or the L command when you have invalid in any of the STATUS fields. If you attempt to use the keys or the command, the following message appears:
Requested function denied... invalid SYSPARMS displayed
Resetting a SYSPARMS Operand Value
To reset the value of a SYSPARMS operand, enter the R (for reset) command with the name of the operand you wish to reset in the command line and press the ENTER key.
R SYSPARMS-operand
SYSPARMS-operand is the name of the SYSPARMS operand whose value you want to reset.
The value of the operand is reset to its original value, and the STATUS field displays a
