dynamic configuration file (DCF)
dynamic configuration file (DCF). An attachment file that is produced by the OSM and
TSM client software and accompanied by an incident report. The DCF contains a
snapshot of the system configuration, the state of the HP NonStop™ server, and
outstanding alarms at the time that the incident report was issued. The DCF is used by
the service provider to avoid having to perform online discovery of the server over
dial-up telephone lines.
Dynamic Host Configuration Protocol (DHCP). An Internet protocol for automating the
configuration of computers that use TCP/IP. DHCP can automatically assign IP
addresses, deliver TCP/IP stack configuration parameters such as the subnet mask
and default router, and provide other configuration information such as the addresses
for printer, time, and news servers.
dynamic information. Information that represents the set of resources that actually exist in
the current configuration of an HP NonStop™ server. Dynamic information is gathered
from a server through the process of discovery. Contrast with static information.
dynamic-link library (DLL). A collection of procedures whose code and data can be loaded
and executed at any virtual memory address, with run-time resolution of links to and
from the main program and other independent libraries. The same DLL can be used by
more than one process. Each process gets its own copy of DLL static data. Contrast
with shared run-time library (SRL). See also TNS/R library.
dynamic loading. Loading and opening dynamic-link libraries under programmatic control
after the program is loaded and execution has begun.
dynamic process configuration. Using Subsystem Control Facility (SCF) to configure a
generic process to always start in a designated primary processor (that is, to be fault
tolerant).
dynamic shared object (DSO). See dynamic-link library (DLL).
Dynamic System Configuration (DSC). A utility used in D-series and earlier release
version updates (RVUs) to make online changes to the configuration of devices and
controllers. Its interactive utility is called the Configuration Utility Program (COUP). In
G-series RVUs, similar functions are performed by Subsystem Control Facility (SCF).
E4SA. See Ethernet 4 ServerNet adapter (E4SA).
earth ground. The connection of the electrical-grounding conductors to a dependable, low-
resistance contact with the soil.
earth-grounding electrode. An electrically conductive rod that is driven into soil, thus
providing an earth-ground connection point for the electrical ground wiring in a building.
A vertical steel column of a building, with its base sunk into soil, can also serve as an
earth-grounding electrode.
earth-grounding electrode system. A grounding network created by bonding together the
grounding means in a building (for example, underground metal water pipes, structural
