API (application programmatic interface).
API (application programmatic interface). A set of services (such as programming
language functions or procedures) that are called by an application program to
communicate with other software components. For example, an application program in
the form of a client might use an API to communicate with a server program. For
NonStop FTAM, the API consists of FTM, APS, and MFM procedures used in FTAM
programming. The NonStop FTAM API also includes the data definitions provided in
the ZFTMDDL file and all language-specific files derived from ZFTMDDL. See also
APS procedures, FTM procedures., and MFM (module file management) procedures.
APLMGR (NonStop OSI/Application Manager). The NonStop subsystem that performs
management functions for NonStop FTAM. The APLMGR subsystem consists of two
entities: the APLMGR process and the management information base (MIB). There is
only one APLMGR per FTAM subsystem.
application. A user program that uses services provided by products such as NonStop
FTAM. The program accesses layers of the OSI Reference Model through the top layer
(Application Layer) to manipulate files on remote computer systems. For NonStop
FTAM, applications can be written in C or TAL.
application entity. The part of an application process that interacts with its peer entity in a
remote application process. In an OSI application, the application entity is the part that
represents the communication functionality necessary for interoperation.
application entity title (AE title). The structured identifier that identifies an application
entity to the OSI network. The AE title is passed as a parameter in the ACSE
A-ASSOCIATE request and returned in the A-ASSOCIATE response. See application
entity.
Application Layer. Layer 7 of the OSI Reference Model. This layer provides the interface
between user programs (application processes) and the OSI network. Layer 7 includes
the standards for services such as file transfer, electronic mail, and terminal access.
Application Manager. See APLMGR (NonStop OSI/Application Manager).
application name. The NonStop OSI/AS term for a reference name used to look up an OSI
address in the local OSI/AS management information base (MIB). In NonStop FTAM
terminology, this name is called the common name. See common name.
application programmatic interface. See API (application programmatic interface).
application service element. See ASE (application service element).
