Security exit processes. These processes determine whether a user has sufficient
command authority to use a Guardian utility and members of the utility’s
command set. Security exit processes usually run as process pairs.
Application processes. Each application process performs a set of functions
according to its class (BK, EM, IS, MS, or NC). Application processes are started as
persistent processes.
Note BK, EM, and NC processes can also run as process pairs. See “Running BK, EM, and NC Processes as
Process Pairs,” later in this section, for more information.
The NCP is the first process started. You start the NCP by using the TACL RUN
command to run the NCP program. The NCP starts all other processes.
The NCP program and the NCP are discussed in more detail in Section 2, “Starting
NonStop NET/MASTER MS.” GMM, security exit, and application processes are
discussed later in this section.
Classes of NonStop NET/MASTER MS Application Processes
As Table 11-1 shows, NonStop NET/MASTER MS, by default, is started with the NC
class application process. Altogether, there are five classes of NonStop NET/MASTER
MS application processes:
The background services (BK) class. This class supports the BSYS, BMON, BLOG,
and LOGP virtual users and their background processing environments, handles
commands submitted to these virtual users, and supports the system-level
LOGPROC NCL procedure.
The event management services (EM) class. This class supports the interface to
Event Management Service (EMS), supports the EMSP virtual user and its
background processing environment, handles commands submitted to this virtual
user, and supports the system-level EMSPROC NCL procedure.
The inter-system services (IS) class. This class supports INMC, ISR, and ROC for
the multiprotocol exchange of commands, command-response messages, and
event messages with another network management application (NonStop
NET/MASTER MS, the SOLVE management services, or NetView).
The multi-user services (MS) class. This class provides the interactive user
environment for NonStop NET/MASTER MS operations and NCL procedure and
panel description file development.
The NonStop NET/MASTER MS consolidated services (NC) class. This class
combines the functions of the BK, EM, IS, and MS process classes in a mode that
requires less memory, fewer executing processes, and reduced disk space.
Regardless of the process class to which it belongs, each occurrence of an application
process is created from the same program file. Additionally, each application process
has either a static or dynamic presence. Application processes and the two types of
process presence are discussed in more detail later in this section.
