summary state
for inclusion in programs, macros, and routines using the SPI procedures; and definition
files in DDL for programmers writing their own subsystems.
summary state. In Distributed Systems Management (DSM)
interfaces to Compaq data
communications subsystems, a summary state is 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 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.
symbolic name. In Distributed Systems Management (DSM)
programmatic interfaces, a
name used in programs to refer to commonly used values, token codes, token maps,
extensible structures, and other related variables for use in management programs.
synchronization point. A marker that a Session Layer
application can insert into the data it
is transmitting, to structure the exchange of data. There are two types: major
synchronization points and minor synchronization points.
Synchronize minor token. One of the four types of Session Layer
tokens that are associated
with functional units.
SYSGEN. The Compaq system generation program, used to configure objects such as
devices, controllers, and input/output processes (IOPS) in a newly installed system or to
update the system when new software is released. Objects to be configured are defined
to SYSGEN in a special configuration file, which can then be coldloaded into the
system. The Compaq Open Systems Interconnection (OSI)
products are not configured
with SYSGEN, but the underlying X.25 Access Method (X25AM) and Tandem LAN
Access Method (TLAM) IOPs are.
Tandem application, presentation, and session (TAPS) process. A process in the OSI/AS
subsystem that performs service and protocol functions for ACSE (in the Application
Layer), the Presentation Layer, and the Session Layer. The TAPS process also performs
some management services in the Distributed Systems Management (DSM)
environment.
Tandem internal token. In Distributed Systems Management (DSM)
, an event message
token that is intended for interpretation and use only by Compaq software.
Tandem LAN Access Method (TLAM). For D4x series only. A Compaq product that
implements, for LANs, the services of the Data Link Layer
and layers below. Replaced
by the Port Access Method (PAM) subsystem for G06x releases.
token. (1) An attribute of a Session Layer
connection, dynamically assigned to one session
service user at a time, that confers the exclusive right to perform a given function. For
example, in half-duplex mode, if a local application holds the data token, it can send
data; before the remote application can send data, it must acquire the data token from the
