NonStop System Glossary

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).
object code library
Synonym for library.
object name
A unique name for a Subsystem Control Facility (SCF) object within a subsystem.
object-name template
A name that stands for more than one Subsystem Control Facility (SCF) object. Such a name includes
one or more wild-card characters, such as * (asterisk) and ? (question mark). See also wild-card
character.
object type
The category of Subsystem Control Facility (SCF) objects to which a specific SCF object belongs.
For example, a specific disk has the object type DISK, and a specific terminal can have the object
type SU. Each subsystem has a set of object types for the objects it manages.
obsolescent
An indication that a feature or facility exists for compatibility with older versions or drafts of a
standard. Obsolescent features or facilities should not be used because they might be removed
from future versions of a standard and therefore might not be portable.
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-accelerated object code
The 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 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.
