Configuring DTCs Step-by-Step
Modify the Network Management Configuration File
You can create or modify a configuration file using a
different name and save it asan 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, rename it as NMCONFIG.PUB.SYS,
validate within NMMGR (SYSGEN cross-validation is
done automatically within NMMGR). Use DTCCNTRL
to shutdown and restart DTS or reboot the system.
Backup
configuration
file name A backup file name must be specified whenever a
configuration file is opened or created. The default
backup configuration file name is NMCBACK.PUB.SYS.
The backup file will be automatically updated with the
contents of the configuration file each time the
configuration file is successfully validated.
Network
directory file
name The Network directory file must be configured for each
new X.25 node (unless you will only be accessing the
node using direct level 3 access). This field is only used
for X.25 network management. The network directory
contains information that one X.25 node needs in order
to communicate with other X.25 nodes. The only
network directory file name supported by HP is
NSDIR.NET.SYS.
Write access
password The password is an optional feature. If a password has
been assigned, you must enter it in the password field
to update the configuration file. It is possible to open
the file without using an assigned password, but the file
will be in read only mode and NMMGR will not accept
any changes.
If a password has not been assigned, you should ignore
the password field. If you want to assign a password for
the system you are configuring, refer to Using the Node
Management Services (NMS) Utilities manual.
Step 3: Configure the Local Node Name
The Main screen is displayed after you press the [Open Config] key
(Figure 3-2). This screen lets you specify the HP 3000 host's name. It
also asks whether you are using the HP 3000 host or an OpenView
Windows Workstation (PC) for DTC management, and if you are using
X.25 or PAD.
