QIO
QIO. A HP product that provides buffers and control blocks for protocol processes,
including TLAM and NonStop IPX/SPX running on the same CPU.
Remote Server Call (RSC). HP extension to Pathway that provides workstation clients with
the ability to access Pathway servers.
Request for Comments. See RFC.
response. In DSM use, the information or confirmation supplied (as part of a response
message) to an application by a subsystem in response to a DSM command.
RFC. (Request for Comments) The name of a series of notes that contain surveys,
measurements, ideas, techniques, and observations, as well as proposed and
accepted Internet protocol standards. RFCs are edited but not referenced. They are
available across the Internet.
RIP. See Routing Information Protocol (RIP).
Routing Information Protocol (RIP). Protocol to control packet forwarding between
routers in a network.
RSC. See Remote Server Call (RSC).
RSCCOM. A command language interface that configures and controls the Transaction
Delivery Process (TDP) and its objects. Used for RSC.
SAC. See ServerNet addressable controller (SAC).
SAP. See Service Advertising Protocol.
SCF. (Subsystem Control Facility) A part of DSM used to provide a common, interactive
management interface for configuring, controlling, and collecting information from HP
data communications products.
SCP. (Subsystem Control Point) In DSM, the management process for all HP data
communications subsystems. There can be several occurrences of this process.
Applications using SPI send all commands for data communications subsystems to an
occurrence of this process, which in turn sends the commands on to the manager
processes of the target subsystems. SCP also processes a few commands itself. It
provides security features, version compatibility, support for tracing, and support for
applications implemented as NonStop process pairs. See also management process or
manager process.
sensitive command. In DSM, a command that can be issued only by a restricted set of
NonStop Kernel users, such as the owner of a subsystem process. For HP data
communications subsystems, the sensitive commands are those that can change the
state or configuration of objects, start or stop tracing, or change the values of statistics
counters. Compare nonsensitive command.
