NonStop System Glossary

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 J-series, H-series, and G-series RVUs, similar functions are performed by
Subsystem Control Facility (SCF).
E
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.
ECC
See error correction code (ECC).
ECL
See emitter-coupled logic (ECL).
ECL plug-in card (PIC)
See emitter-coupled logic (ECL) plug-in card (PIC).
