The Open Configuration/Directory File screen (#1) shown in Figure 2-2 "Open Configuration/Directory Screen" is the first screen displayed when you run NMMGR.

Figure 2-2 Open Configuration/Directory Screen

[Open Configuration/Directory Screen]

To create or modify a configuration, enter the configuration file name and press the [Open Config] key. If the configuration file does not already exist, NMMGR will ask you to press the [Open Config] key again to confirm creation. Upon pressing the [Open Config] key the Main screen (#2) will appear as shown in Figure 2-3 "Main Screen".

To change the default backup file name, enter a new name in the backup configuration file name field before you open the configuration file.

To create or modify a network directory, enter the network directory file name and press the [Open Directry] key. If the directory file does not already exist, NMMGR will ask you to press the [Open Directry] key again to confirm creation. Upon pressing the [Open Directory] key, the Network Directory Main screen (#8) will appear as shown in Chapter 13 "Network Directory" (Figure 13-3 "Network Directory Main Screen").

If a write access password has been assigned, you must enter the password in the write access password field before you will be able to open a configuration or directory file for write access or to create a new configuration or directory file.

To open a file in read only mode if a write access password has been assigned, leave this field blank.

NOTE: The write access password is optional. If you do not choose to assign a password, you will be able to update the configuration file at any time it is opened. For information on how to assign a write access password, refer to the information about the password maintenance mode command in Using the Node Management Services (NMS) Utilities.

Fields

Configuration file name

The only valid configuration file name the system recognizes for use by the network subsystems is NMCONFIG.PUB.SYS. You can, however, create or modify a configuration file using a different name and save it as an offline configuration file. You can use offline configuration files as a means of creating and storing configurations that you want to use in the future. When you are ready to use an offline configuration file, simply rename it as NMCONFIG.PUB.SYS and reboot the system. (Keep in mind that any file you use as a configuration file must be successfully validated before you try to use it.)

Backup configuration file

A backup file name must be specified whenever a configuration file is opened or created. The default backup configuration file name is NMCBACK.group.account. The backup file will be automatically updated with the contents of the configuration file each time the configuration is successfully validated.

Network directory file name

The name of the network directory file you want to create or update. The network directory uses a KSAM file pair, therefore two files are actually created for each network directory. The only file name the system recognizes as a network directory data file is NSDIR.NET.SYS. The only file name the system recognizes as a network directory key file is NSDIRK.NET.SYS. (NSDIRK.NET.SYS is generated automatically when NSDIR.NET.SYS is created.)

You can create offline directories in the same way that you can create offline configuration files, by using a different file name when you create and save network directory information. When you are ready to use the offline directory, you must be sure to rename both the data file and the key file to the system-recognized names.

Network directory screens are discussed in Chapter 13 "Network Directory" of this manual.

Write access password

The password is an optional feature. If a password has been assigned, you must enter the password in the write access password field in order to update the configuration file. It is still possible to open the file without using an assigned password, but the file will be in read only mode and NMMGR will accept no changes to the file.

If no password has been assigned, you should ignore the write access password field.

If you want to assign a password for the system you are configuring, refer to Using the Node Management Services (NMS) Utilities.
