Introduction
NMMGR
NMMGR
The Node Management Configuration Manager (NMMGR) is the
utility used to create or update configuration and network directory
files. These files define the configuration for terminal and serial printer
connections and networked connections for HP e3000 computers. Use
NMMGR to configure each of the following subsystems:
• The distributed terminal subsystem (DTS), which defines
connections for terminals, printers, and other serial devices that will
be able to communicate with the system.
• The Network Services (NS) subsystem, which defines the operation
of NS links and services between HP e3000 systems.
• The BSC subsystem, which defines BSC communication links
between HP e3000 and IBM systems.
• The SNA subsystem, which defines SNA communication links
between HP e3000 and IBM systems.
Configuration File
NMMGR stores configuration information in a special MPE
configuration file that contains the data needed by the system for
networking and terminal-to-system communications. The file has the
MPE file code NCONF and may contain three kinds of data:
• Standard software operating parameters, such as limits on using
MPE resources.
• Node-specific information, such as the name of the local computer
and its network address.
• Information needed by the network software in order to
communicate with other nodes to which the local node is connected.
The configuration file must be named NMCONFIG.PUB.SYS in order to be
recognized and used by the system. You may, however, create a
configuration file using any valid MPE file name and rename it as
NMCONFIG.PUB.SYS when you are ready for the system to use the
configuration information it contains.
NMCONFIG.PUB.SYS must reside on LDEV1 in order to be recognized.
The system does not have access to other LDEVs at startup and the
configuration file is needed at that time.
With a few exceptions, the changes you make to the NMCONFIG.PUB.SYS
file take effect only when the system is rebooted. In most cases, you
should avoid making changes to an active configuration file (one that
the system is currently using). There are some changes, however, that
may be made while the network is operating. Refer to the
