By using an external DSNM system: that is, by sharing DSNM with another
management application. The DSNM processes are started externally to NonStop
NET/MASTER MS, either before or after NonStop NET/MASTER MS is started.
The names of the command server process and the existing CIP in the external
DSNM system are defined in the CONFIG file. (Definitions for other external
DSNM processes are not required.) The NCP does not attempt to locate or start
these (or any other) DSNM processes when NonStop NET/MASTER MS is started.
When an OPSYS command is issued, NonStop NET/MASTER MS attempts to
locate the defined command server process or the CIP (whichever process is
appropriate) to process the DSNM command.
Additionally, you can configure NonStop NET/MASTER MS to not use a DSNM
system. To do so, you configure valid but nonexistent process names for the
command server process and the CIP in the CONFIG file. The NCP does not attempt
to locate or start these (or any other) DSNM processes when NonStop NET/MASTER
MS is started. When an OPSYS command is issued, NonStop NET/MASTER MS
attempts to locate the defined nonexistent command server process or the CIP
(whichever process is appropriate) to process the DSNM command, but fails.
Using DSNM from NonStop NET/MASTER MS is discussed in more detail later in
this section.
Operating Modes NonStop NET/MASTER MS can run in three different operating modes: basic mode,
extended basic mode, and advanced mode.
Each operating mode requires at least one NCP, GMM process, and security exit
process, each of which usually runs as a process pair. However, the configuration of
the NCP, GMM processes, and security exit processes does not define the operating
mode. Additionally, the way NonStop NET/MASTER MS makes use of DSNM is not
significant in determining the operating mode. Rather, the operating mode is defined
by the combination of application process classes.
There are two ways to start NonStop NET/MASTER MS in each operating mode:
without or with a CONFIG file.
Basic Mode
NonStop NET/MASTER MS runs in basic mode when started with its default startup
configuration. Section 1, “Introduction to Managing NonStop NET/MASTER MS,”
discusses the default startup configuration. Section 2, “Starting NonStop
NET/MASTER MS,” discusses starting NonStop NET/MASTER MS using the default
startup configuration.
In a NonStop NET/MASTER MS system running in basic mode, one static or dynamic
NC process is present, but no BK, EM, IS, or MS processes are present. Basic mode is
discussed in more detail later in this section.
