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 as shown.

When you are finished entering maintenance mode commands, type EXIT at the prompt to leave the maintenance mode interface and return to screen mode.

Running Maintenance Mode from a Batch Job

You can also access maintenance mode directly from a batch job by running NMMGR within a job stream or by running NMMGR with a file equation for the formal designator NMMGRCMD set to a command file. An example of such an equation is:

:FILE NMMGRCMD=CMDFILE

Command input is echoed to $STDLIST if you are running NMMGR from within a job stream or when the input is read from a command file.

You can create a command file using any editor that is capable of generating ASCII output. Blank command lines may be entered freely.
