dynamic-link library (DLL)
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
steel, and ground rods into the earth) and bonding them to the switchgear at the
facility’s main electrical service entrance.
ECL. See emitter-coupled logic (ECL).
ECL plug-in card (PIC). See emitter-coupled logic (ECL) plug-in card (PIC).
ECL ServerNet cable. See emitter-coupled logic (ECL) ServerNet cable.
EDIT file. In the Guardian file system, an unstructured file with file code 101. An EDIT file
can be processed by either the EDIT or PS Text Edit (TEDIT) editor. An EDIT file
typically contains source program or script code, documentation, or program output.
Open System Services (OSS) functions can open an EDIT file only for reading.
