subordinate names option
subordinate names option. In DSM interfaces to HP data communications subsystems,
the designation that the object name given in a command stands not just for itself but
also for the names of objects at lower levels in a hierarchy. For NonStop IPX/SPX, the
SUB option is required for the START SUBSYS, STOP SUBSYS, and ABORT
SUBSYS commands. When this option is present in a command, the subordinate
names are implied even though they are not given explicitly.
subsystem. (1) The software and/or hardware facilities that provide users with access to a
set of communications services. (2) 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.
Subsystem Control Facility. See SCF.
Subsystem Control Point. See SCP.
subsystem ID (SSID). In DSM programmatic interfaces, a data structure that uniquely
identifies a subsystem. It consists of the name of the owner of the subsystem (such as
HP), a subsystem number that identifies that particular subsystem, and a subsystem
version number.
summary state. In DSM interfaces to HP 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 to the management of an object, whereas a state might convey other types of
information about the object. Second, summary states are defined the same way for all
HP data communications subsystems, whereas the set of possible states differs from
subsystem to subsystem. The management programming interfaces to HP data
communications subsystems refer to summary states rather than to states. States for
NonStop IPX/SPX objects are ABORTING, DEFINED, STARTED, STARTING,
STOPPED, and STOPPING.
SYSGEN. The HP system-generation program, used to configure objects such as devices,
controllers, and I/O processes in a newly installed Nonstop K-series system, or to
update the system. Objects to be configured are defined to SYSGEN in a special
configuration file, which can then be cold loaded into the system.
TAL. See Transaction Application Language.
Tandem LAN Access Method (TLAM). The TLAM software provides an industry-standard
interface for accessing LANs from the NonStop system. Based on the IEEE 802.2
Logical Link Control standard, TLAM supports 802.2 Type 1 connectionless service as
well as the Multilan/NETBIOS protocol. With TLAM, you do not need to write
applications for a specific type of LAN.
