Compaq TSM Service Application
Compaq TSM Service Application. A component of the Compaq TSM client software. The
TSM Service Application enables you to communicate with an HP NonStop™ S-series
server when the HP NonStop Kernel operating system is running. When the operating
system is not running, communication must take place using the TSM Low-Level Link.

.
compiler extended-data segment. A selectable segment, with ID 1024, created and
selected automatically in many (but not all) TNS processes. Within this segment, the
compiler automatically allocates global and local variables and heaps that would not fit
in the TNS user data segment. A programmer must keep this segment selected
whenever those items might be referenced. Any alternative selections of segments
must be temporary and undone before returning.
complex instruction-set computing (CISC). A processor architecture based on a large
instruction set, characterized by numerous addressing modes, multicycle machine
instructions, and many special-purpose instructions. Contrast with reduced
instruction-set computing (RISC).
compliance. The testing and verification process that precedes X/Open licensing.
computer-room power center (CRPC). The equipment that conditions and distributes
facility power to computer-room equipment. The CRPC typically houses an
electrostatically shielded isolation transformer, power distribution panels (PDPs), a
main shunt-trip circuit breaker, and voltage indicators. Also referred to as a power
distribution unit (PDU) or power distribution center.
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.
conduit. A tubular raceway, usually constructed of rigid or flexible metal, through which
insulated power and ground conductors or data cables are run. Nonmetallic conduits,
although available, are not recommended.
CONFAUX file. The auxiliary configuration file created by the Distributed Systems
Management/Software Configuration Manager (DSM/SCM) tools. The CONFAUX file
contains a list of the code files and system files that are needed to build the new HP
NonStop™ Kernel operating system. HP recommends that you avoid making any
changes to your CONFAUX file.
CONFBASE file. In G-series release version updates (RVUs), the basic system
configuration database file, which is stored on the $SYSTEM.SYS
nn subvolume. See
