instance data
the same program simultaneously. Also, instance data refers to global data of a
program or library. Each process has its own instance of the data.
instance data. For each process using a dynamic-link library, a data segment area
containing the global variables used by the library.
interactive mode. A mode of operation that is characterized by having the same input and
output device (a terminal or a process) for the session. If a terminal is used, a person
enters a command and presses Return. If a process is used, the system interface waits
for the process to send a request and treats the process in the same manner as a
terminal. Contrast with
noninteractive mode .
Kernel subsystem. In G-series and H-series release version updates (RVUs), the
subsystem for configuration and management of the Subsystem Control Facility (SCF)
subsystem managers that are generic processes, some system attributes, and the
ServerNet X and Y fabrics.
Kernel subsystem manager process. The graphical user interface (GUI) that starts and
manages other generic processes, some system attributes, and the ServerNet X and Y
fabrics in G-series release version updates (RVUs). The $ZZKRN Kernel subsystem
manager process is started and managed by the $ZPM persistence manager process.
keyword. A character sequence recognized by a command process.
late binding. At load time, binding a symbolic reference in a dynamic-link library (DLL) to a
definition in a loadfile that appears on the program’s loadList rather than the one found
on the DLL’s linker searchList. Late binding occurs in either of these cases:
•
The loader resolves a symbol that is unresolved by any loadfile on the linker
searchList.
•
The loader binds a symbol in a DLL to the first definition it finds on the program’s
loadList, and this is not the first definition that was encountered on the linker
searchList.
For localized loadfiles, the linker and loader searchLists are the same, so late binding
does not occur.
ld utility. A utility that collects, links, and modifies code and data blocks from one or more
position-independent code (PIC) object files to produce a target TNS/R native object
file. See also
eld utility and nld utility .
legacy system. An operating system that is not open but from which applications must be
ported or users transferred.
libList. The list of libraries to be loaded along with a loadfile. When linking the loadfile, the
linker constructs the libList from the names of libraries specified in the linker’s
command stream. It stores the libList within the loadfile.
