noninteractive mode
noninteractive mode. A mode of operation that usually involves a command file (an EDIT
file that contains a series of commands). Contrast with interactive mode.
object code accelerator (OCA). See TNS Object Code Accelerator (OCA).
object code file. A file containing compiled machine instructions for one or more routines.
This file can be an executable loadfile for a program or library or a not-yet-executable
linkfile for some program module. On other systems, an object code file is also known
as a binary or as an executable.
object code interpreter (OCI). See TNS Object Code Interpreter (OCI).
OCA. (1) The command used to invoke the TNS Object Code Accelerator (OCA) on a
TNS/E system. (2) See TNS Object Code Accelerator (OCA).
OCA region loading. A task performed when necessary by the TNS emulation software for
TNS/E machines. This task involves mapping into memory the Intel® Itanium®
instructions and any tables needed at run time from the TNS Object Code Accelerator
(OCA) region (called the Itanium instruction region) of an OCA-generated object file.
OCA region of an object file. The region of a TNS Object Code Accelerator (OCA)-
generated object file, also called the Intel® Itanium® instruction region, that contains
Itanium instructions and tables necessary to execute the object file on a TNS/E system
in TNS accelerated mode. The TNS Object Code Accelerator (OCA) creates this
region. See also OCA-accelerated object code. Contrast with Accelerator region of an
object file.
OCA-accelerated object code. The Intel® Itanium® instructions that result from processing
a TNS object file with the TNS Object Code Accelerator (OCA).
OCA-accelerated object file. A TNS object file that has been augmented by the TNS
Object Code Accelerator (OCA) with equivalent but faster Intel® Itanium® instructions.
An OCA-accelerated object file contains the original TNS object code, the OCA-
accelerated object code and related address map tables, and any Binder and symbol
information from the original TNS object file. An OCA-accelerated object file also can
be augmented by the Accelerator with equivalent MIPS RISC instructions.
OCA-generated Itanium instructions. See Intel® Itanium® instructions.
OCI. See TNS Object Code Interpreter (OCI).
object code library. Synonym for library.
object file. A file generated by a compiler or linker that contains machine instructions and
other information needed to construct the executable code spaces and initial data for a
process. The file may be a complete program that is ready for immediate execution, or
it may be incomplete and require linking with other object files before execution. See
also TNS object file, TNS/R native object file, and TNS/E native object file.
