Architecture Overview
in a NonStop system. Only one instance of the domain coordinator process exists per
NonStop system.
The process broker, configuration subscriber, and redirector processes coordinate with
other processes to provide link-management functions, as shown in Figure 1-1. The
box encompassing the three processes indicates that they share memory and are
tightly bound. If any of these processes fails, the other processes may fail soon
thereafter.
As shown in Figure 1-1, the domain coordinator process also shares memory with the
process broker, configuration subscriber, and redirector process in the CPU in which it
resides and is, therefore, also tightly bound to the processes in that CPU.
Figure 1-1 and Figure 1-2 show only one PATHMON and PATHCOM process.
However, a system can contain multiple PATHMON and PATHCOM processes, in
addition to multiple server classes and clients.
