responder.
responder. The file-service user that accepts an initiator’s request to establish an FTAM
regime. In NonStop FTAM, the responder is a process that services FTAM requests
initiated from remote systems on an OSI network. The NonStop responder acts as an
FTAM file server, mapping FTAM requests into Guardian file operations and providing a
translation between Guardian file structures and FTAM file structures. The NonStop
responder has no programmatic interface. Contrast with initiator.
responding address. The OSI address of the responder that responds to an association
request from an initiator in an FTAM application. Contrast with called address and
calling address.
responding user. The responder that responds to an association request from an initiator in
an FTAM application. Contrast with called address and calling address.
response primitive. A primitive issued when a service user (entity) wants to respond to an
event (for confirmed services only). This is one of four types of service primitives. See
service primitive.
response procedure. A procedure called by your application to send response primitives to
indications from the FTAM responder. See response primitive.
restart-data-transfer functional unit. An ISO FTAM functional unit that allows the transfer
of data to be interrupted and immediately restarted in a current transfer.
reverse traversal. Traversal through the nodes of an FTAM file in reverse order (last to
first).
root FADU. The first-level FADU in an FTAM file. In the case of FTAM-1 and FTAM-3 files,
the complete file is one FADU and so can be considered the root FADU. FTAM-2 files
consist of two levels of FADUs in a hierarchical structure. The root FADU provides
access to the complete file. See FADU (file-access data unit).
root node. The first-level node in a hierarchical file. See root FADU.
Safeguard. The NonStop system-software security package that implements three security
features: user authentication, object-access authorization, and auditing. sample time.
In SCF, the date and time that the currently displayed statistics for an object were
gathered. The sample time is displayed by the STATS command along with the
statistics.
SAP (service access point). The point at which an implementation of a given OSI layer
provides its services to an implementation of the layer above it. The SAP is highly
system-dependent and generally refers to the way interlayer communication is
accomplished.
SCF (Subsystem Control Facility). A utility that provides a common, interactive
management interface for configuring, controlling, and collecting information from
NonStop data communications products.
