DSNM Processes DSNM is a product used for monitoring and controlling subsystem objects in a
network and (from NonStop NET/MASTER MS only) for communicating with
conversational-mode Guardian utilities. NonStop NET/MASTER MS is distributed
with Distributed Systems Management Solutions (DSMS)/DSNM.
The Command Server and Conversational Interface Processes
NonStop NET/MASTER MS provides an interface to DSNM through two DSNM
processes:
The command server process. NonStop NET/MASTER MS communicates with
this process to handle DSNM subsystem commands (commands to SPI-based
subsystems). These are OPSYS subsystem commands, which are used to monitor
and control subsystems in a network.
The conversational interface process (CIP). NonStop NET/MASTER MS
communicates with this process to handle DSNM utility commands. These are
OPSYS utility commands, which are used to start and terminate interactive
sessions with Guardian utilities, such as PUP.
The command server process and the CIP are discussed in more detail later in this
section.
Using DSNM From NonStop NET/MASTER MS
There are two ways for NonStop NET/MASTER MS to make use of the facilities
provided by DSNM:
By using a DSNM system started by the NCP. There are two ways to do so:
By using the default startup configuration for DSNM processes. Either no
CONFIG file is used or the command server process and the CIP are not
defined in the CONFIG file. The command server process and the CIP are
created using default startup configuration values. The NCP starts these (and
certain other) DSNM processes when NonStop NET/MASTER MS is started.
When an OPSYS command is issued, NonStop NET/MASTER MS attempts to
locate the command server process or the CIP (whichever process is
appropriate) to process the DSNM command.
By using a customized startup configuration for DSNM processes. The DSNM
processes to be used by NonStop NET/MASTER MS are defined in the
CONFIG file. The specified DSNM processes are created using the specified
configuration values. The NCP starts the specified DSNM processes when
NonStop NET/MASTER MS is started. If a DSNM process is not defined, it is
not 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.
