Using NMMGR in Maintenance Mode

Using Maintenance Mode

NMMGR’s maintenance mode is a character mode interface used to

manage both network directory and conﬁguration ﬁles. It can be used

interactively, from within the screen mode interface, or as a set of

commands entered via a batch job.

Maintenance mode can generate a job stream to sequentially update

directories on a list of NS nodes. This feature saves you from manually

changing the network directory ﬁles of every node on a network when

you make a conﬁguration change. You deﬁne the list of nodes to be

updated by this automated process. Additionally, the process provides

logging information and is recoverable.

Maintenance mode commands are read from the formal ﬁle designator

NMMGRCMD, which defaults to $STDINX. You can redirect the input to

come from a standard ASCII ﬁle by using a ﬁle equation for NMMGRCMD.

Entering Maintenance Mode from Screen Mode

You can access maintenance mode from within screen mode, execute

one or more maintenance mode commands, and return to screen mode.

There are two methods you can use to enter the maintenance interface

from screen mode. The two methods are as follows:

• Enter the screen mode command NM[MGRCMD] in the command

window of any screen and press

[ENTER].

• Press the

[Maint Mode] function key from the Network Directory

Main screen.

When you use either method, a screen appears with the maintenance

mode prompt:

NMMGR>

When you enter maintenance mode from screen mode the interface is

interactive. You can enter any appropriate maintenance mode

commands at the prompt. In some cases, a command will prompt you

for additional input which you can enter by typing a response to the

new command prompt. When each command has completed execution,

you will be returned to the maintenance mode prompt shown above.

When you are ﬁnished entering maintenance mode commands, type

EXIT at the prompt to leave the maintenance mode interface and

return to screen mode.
