cluster controller
cluster controller. A device that controls access (I/O operations) to a group of terminals or
printers connected to it. A cluster controller may be controlled by a program stored and
executed in the unit, or it may be entirely controlled by hardware.
CNM interface. A SNAX communications network management interface.
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.
communication controller. An IBM front-end processor that directs the transmission of
data over an SNA network. Contrast with communications controllers.
communications controllers. A generic term for hardware that controls physical
connections to NonStop systems. A device that directs the transmission of data over
the data links of a network; its operation may be controlled by a program executed in a
processor to which the controller is connected, or it may be controlled by a program
executed within the device. Contrast with communication controller.
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.
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.
configuration. (1) The arrangement of enclosures, system components, and peripheral
devices into a working unit. (2) The definition or alteration of characteristics of an
object.
configuration file. In G-series and H-series RVUs, one of the following files: CONFBASE,
CONFIG, one or more saved configuration files named CONFxxyy, and CONFSAVE.
See also system configuration database
. In pre-G-series RVUs, the configuration file is
either the OSCONFIG file used by the Configuration Utility Program (COUP) or the
CONFTEXT file used by SYSGENR.
Configuration Utility Program (COUP). A utility used in D-series and earlier RVUs to
make online changes to the configuration of devices and controllers. COUP is part of
the Dynamic System Configuration (DSC) facility. In G-series and H-series RVUs,
COUP functions are performed by the Subsystem Control Facility (SCF).
