command
command. A demand for action by or information from a subsystem or the operation
demanded by an operator or application. A command is typically conveyed as an
interprocess message from an application to a subsystem.
command file. An EDIT file that contains a series of commands and serves as a source of
command input.
communications line interface processor (CLIP). The major programmable device within
the ServerNet wide area network (SWAN) concentrator, providing link-level protocol
and a software interface to the host. The CLIP stores and implements specific
communications protocols.
communications line. A two-way link consisting of processing equipment, I/O devices,
protocol conventions, and cables that connect a computer to other computers.
communications line interface processor (CLIP). The major programmable device within
the ServerNet wide area network (SWAN) concentrator, providing link-level protocol
and a software interface to the host. The CLIP stores and implements specific
communications protocols.
Communications Management Interface (CMI). A utility used in D-series and earlier
RVUs to make online changes to the configuration of ATP6100, CP6100, and
EnvoyACP/XF communications subdevices. In G-series RVUs, CMI functions are
performed by the Subsystem Control Facility (SCF).
communications subsystem. The combination of data communications hardware and
software processes that function together as an integrated unit to provide services and
access to wide and local area networks.
Compaq TSM. Identifies a client or server software component used to manage or service
HP NonStop™ S-series servers.
concentrator manager process (ConMgr). A process provided as part of the wide area
network (WAN) subsystem. The ConMgr process runs in each processor that supports
WAN products and provides management functions to the WAN subsystem and WAN
products, such as downloading data link control (DLC) tasks to the communications
line interface processors (CLIPs) on the ServerNet wide area network (SWAN)
concentrator and selecting the preferred path for the DLC tasks.
CONFBASE file. In G-series RVUs, the basic system configuration database file, which is
stored on the $SYSTEM.SYSnn subvolume. See also configuration file.
CONFIG file. In G-series RVUs, the current system configuration database file, which is
stored on the $SYSTEM. ZSYSCONF subvolume. See also configuration file.
configuration. The definition or alteration of characteristics of an object.
