enoft utility
the emulated system. For example, a TNS/R or TNS/E system emulates the behavior
of a TNS system when executing interpreted or accelerated TNS object code.
enoft utility. A utility that reads and displays information from TNS/E native object files.
See also noft utility.
EPTRACE. A performance investigation tool for Open System Services (OSS) and
Guardian environments running H-series RVUs. It is designed to count, trace, locate,
and provide a log of millicode-corrected misalignments in TNS stumble events.
exact point. See memory-exact point and register-exact point.
executable. See object code file.
Executable and Linkable Format (ELF). A common standard for executable files and
object code. On HP NonStop™ servers, ELF replaced the less extensible Common
Object File Format (COFF) for native files.
execution mode. The emulated or real instruction set environment in which object code
runs. A TNS system has only one execution mode: TNS mode using TNS compilers
and 16-bit TNS instructions. A TNS/R system has three execution modes: TNS/R
native mode using MIPS native compilers and MIPS instructions, emulated TNS
execution in TNS interpreted mode, and emulated TNS execution in TNS accelerated
mode. A TNS/E system also has three execution modes: TNS/E native mode using
TNS/E native compilers and Intel® Itanium® instructions, emulated TNS execution in
TNS interpreted mode, and emulated TNS execution in TNS accelerated mode.
explicit DLL. See explicit dynamic-link library (explicit DLL).
explicit dynamic-link library (explicit DLL). A dynamic-link library (DLL) that is named in
the libList of a client or is a native-compiled loadfile associated with a client.
export. To offer a symbol definition for use by other loadfiles. A loadfile exports a symbol
definition for use by other loadfiles that need a data item or function having that
symbolic name.
extended data segment. See selectable segment.
external entry-point (XEP) table. A table located in the last page of each TNS code
segment that contains links for calls (unresolved external references) out of that
segment.
fault domain. In a fault-tolerant system, a module that can fail without causing a system
failure.
fault tolerance. The ability of a computer system to continue processing despite the failure
of any single software or hardware component within the system.
field. In a structured programming language, an addressable entry within a data structure.
