loadfile

run-time loader and run-time linker. The loader for TNS and for TNS/R native programs
and libraries that are not position-independent code (PIC) is part of the operating
system. For PIC loadfiles, a loader called RLD works with the operating system to load
programs and libraries.

loadfile. An executable object code file that is ready for loading into memory and executing

on the computer. Loadfiles are further classified as executable programs (containing a
main routine at which to begin execution of that program) or executable libraries
(supplying routines or variables to multiple programs or separately loaded libraries). A
TNS code file might be both a loadfile and a linkfile. Native code files are never both.

linkfile

.

loadList. A list of all the libraries that must be loaded for a given loadfile to execute. A

loadfile’s loadList includes all the libraries in the given loadfile’s libList plus all the
libraries in those loadfiles’ libLists, and so forth. It does not include the implicit libraries.
The loadList order is the sequence in which these loadfiles are to be loaded when they
are not already loaded by a previous operation. The loadList of the program includes
all the loadfiles present in the process, in the order they were loaded.

local millicode. Emulation millicode routines that are physically copied into each TNS

program code file when accelerated for TNS/E. These are a small and frequently used
subset of the full set of accelerated-mode millicode routines located in the system’s

TNS Emulation Library

. The program’s calls to its local copy of these routines are

faster and more compact than DLL calls to the external library.

logical processor. See

processor

.

logical segment. A single data area consisting of one or more consecutive 128-kilobyte

unitary segments that is dynamically allocated by a process. The two types of logical
segments are selectable segments and flat segments. See also

selectable segment

and

flat segment

.

logical processor. The combination of equivalent processor elements in the processor

slices that are running in the same instruction stream in loose lock-step.

login. The activity by which a user establishes a locally authenticated identity on a server.

Each login has one login name.

login name. A user name associated with a session.

logon sequence. The process through which the HP NonStop™ server to be managed is

determined, the security constraints to interact with that server are met, and a
connection with that server is established.

main memory. Data storage, specifically the chips that store the programs and data

currently in use by a processor.

memory-exact point. A potential breakpoint location within an accelerated object file at

which the values in memory (but not necessarily the values in registers) are the same
