string segment
string segment. A portion of a string value consisting of zero or more contiguous octets of its
representation.
subject. In event management, a device, process, or other named entity about which a given
event message has information.
subnetwork. In general, a network that participates in a larger network, possibly through the
use of gateways or bridges.
In OSI, one or more intermediate systems that provide relaying and through which end
systems may establish network connections.
subobject. An object that is an attribute of another object.
SUBSYS object. An object type, used in OSI/MHS management interfaces, that identifies the
subsystem as a whole. You use the SUBSYS object to configure general aspects of the
subsystem and to inquire about the subsystem as a whole.
subsystem. The software and/or hardware facilities that provide users with access to a set of
communications services.
In DSM, a program or set of processes that manages a cohesive set of objects. Each
subsystem has a process through which applications can request services by issuing
commands defined by that subsystem; in some cases, this process is the entire
subsystem. Many subsystems also have interactive interfaces.
See also OSI/MHS subsystem.
Subsystem Control Facility. See SCF.
Subsystem Control Point. See SCP.
subsystem ID. See SSID.
Subsystem Programmatic Interface. See SPI.
summary state. In DSM interfaces to Compaq data communications subsystems, one of the
generally defined possible conditions of an object, with respect to the management of
that object. A summary state differs from a state in two ways. First, a summary state
pertains only to the management of an object, whereas a state may convey other kinds of
information about the object. Second, summary states are defined the same way for all
Compaq data communications subsystems, whereas the set of possible states differs
from subsystem to subsystem. The management programming interfaces to Compaq
data communications subsystems refer to summary states rather than to states.
Examples of summary states are STARTED, STOPPED, SUSPENDED, and
ABORTING.
superobject. An object that has other objects for one or more of its attributes.
SUT (site update tape). The tape on which Compaq ships its software for installation. The
product files on the SUT tape are grouped into distribution subvolumes (DSVs), the
