Overview of the
Processing
Environment
The NonStop NET/MASTER MS processing environment is made up of two groups of
cooperating processes: NonStop NET/MASTER MS processes and DSNM processes.
This subsection provides an overview of the NonStop NET/MASTER MS processing
environment. The subsection introduces concepts you must understand before you
can successfully configure the processing environment. All concepts introduced in
this subsection are discussed in more detail later in this section.
NonStop NET/MASTER MS
Processes
NonStop NET/MASTER MS processes include the NonStop NET/MASTER MS
control process (NCP) and other processes that are always started by the NCP.
(DSNM processes are excluded because they need not be started by the NCP.)
Table 11-1 lists the program file name used to start each process type and the process
name allocated when NonStop NET/MASTER MS is started using its default startup
configuration. Appendix A, “File Reference,” has more information about NonStop
NET/MASTER MS program files.
Table 11-1. NonStop NET/MASTER MS Programs and Processes
Process Type Program File Name
∗
Default Process Name Default Process Class
NCP NCP $pNNM N.A.
GMM process NGM $pG00-$pG15 N.A.
Security exit process SECEXIT $pNN0 N.A.
Application process NMNC0001 $pnnn NC
∗∗
∗
By default, all NonStop NET/MASTER MS program files reside in the ZNNM subvolume on
the installation volume.
N.A. Not applicable.
p The NonStop NET/MASTER MS process character. As discussed in Section 2, “Starting
NonStop NET/MASTER MS,” the process character is the first character of the name of the
NCP. You specify the name when you run the NCP program. Whenever the NCP starts a
new process, the process character is the first character of the new process name.
nnn A number allocated by the NCP. The NCP creates the name using the
CREATEPROCESSNAME procedure call if the process character is Z.
∗∗
The NCP uses the third and fourth characters of the file name, which are NC, to determine
the process class.
Types of NonStop NET/MASTER MS Processes
As Table 11-1 shows, there are four types of NonStop NET/MASTER MS processes:
The NCP. This process manages all processes in the NonStop NET/MASTER MS
processing environment, and starts and stops other processes within the
processing environment as required. The NCP usually runs as a process pair.
GMM processes. These processes serve as a conceptual repository of information
accessed and shared by all NonStop NET/MASTER MS processes. GMM
processes usually run as process pairs.
