Management Interfaces
•
The Distributed Name Service (DNS)—a subsystem that manages a distributed
database of names for network objects, facts about object relationships, and
instructions for replicating name definitions on remote nodes.
Figure 1-2 illustrates a Pathway subsystem that uses the SPI and EMS procedures for
subsystem control and event management.
Management Interfaces
There are two ways to configure and control Pathway/iTS: either interactively, by
entering PATHCOM commands at a terminal, or programmatically, by writing a
management application program. Both of these methods allow you to send
commands and instructions to PATHMON, the process that monitors your subsystem
and directs its activities. Figure 1-3 on page 1-6 illustrates these two interfaces and
their relationship to a PATHMON process.
