Glossary

A set of restrictions that dictates how the information in a file is accessed; you can specify access contexts only when reading a file.

Attributes that define the properties that exist only while a specific FTAM connection is being used; these attributes are not part of the file.

A uniquely identified component of your application program that associates it with OSI; may be an FTAM initiator or FTAM responder.

Your means of accessing the FTAM services (e.g., ft_select()).

Any of the services provided to you in the Application layer of the OSI model (e.g., FTAM and ACSE).

An ISO term, synonymous with ``connection.''

An OSI layer seven protocol that provides association establishment, abort, and association termination.

Information that states a property of a file and takes a set of defined values, with each value having a defined meaning.

A unique identifier of a connection for the duration of that connection.

A set of restrictions that specify the allowable file structures and the ways in which access actions can modify the structures.

A function that does not depend on the use of other FTAM functions.

A function that depends on the use of other FTAM functions; you must call context sensitive functions in a specific order.

Data structures used for passing information between user application programs and FTAM applications entities. The DCBs vary, depending on the function call.

The smallest piece of data whose identity is preserved when transferred by the Presentation Service. A data element may convey file contents information or protocol control information.

The file unit that contains the actual file contents; a data unit may contain file structuring information or data elements.

The specification that defines the type of file contents by specifying the allowable constraint sets.

An FTAM file that contains only a root node with no associated data unit or node name.

The synchronous or asynchronous invocation of an FTAM function.

A value used to uniquely define an event; returned on asynchronous calls.

A means of identifying the FADU; location is the only valid value.

The inspection, modification, replacement, or erasure of a file's contents or a portion of it.

The smallest unit of the file access structure on which you can transfer, delete, extend, replace, or insert; contains zero or more data unit; each FTAM file consists of one or more FADUs.

The name and other identifiable properties that describe a file, excluding file contents.

A file's data units, node names, and structuring information that you can manipulate during the File Open regime.

The creation and deletion of files; the inspection or manipulation of file attributes.

A view of a file's structure.

The blocks of information transferred between FTAM initiators and FTAM responders.

The portion of the application entity that invokes the FTAM service.

A function that moves a part or the whole of a file's contents between open systems.

An OSI layer seven protocol that allows peer-to-peer file transfer, record access, and file management.

See File Transfer, Access and Management

The protocol followed by FTAM to accomplish file transfer, access, and management.

The executable name for an HP-UX FTAM initiator; sends your request to an FTAM responder.

The executable name for an HP-UX responder; daemon process that provides the interface for the HP-UX file system (real filestore) to the FTAM VFS.

A collection of FTAM functions that are transferred as a single FPDU.

A function that performs a sequence of low level functions, thereby eliminating the need to call the low level functions individually.

Notification that a request arrived at its destination; notification that information is available. For example, a connect indication occurs when an FTAM responder receives your connect request (ft_connect( )).

The database that stores the initial OSI network configuration.

The entity that submits requests on your behalf; when you call a function, the initiator sends your request to an FTAM responder.

The United Nations body that conducts the balloting and ratification procedures for international communications standards.

A diagnostic tool used to record significant network events; logging is always enabled while the network is operational.

A function that provides the lowest level of service for the MAP 3.0 application interface; a LLS does not contain a sequence of other calls.

A seven layer communications specification; allows multivendor communication among factory automation equipment without custom links.

An addressable point in the Network layer that provides services to the Transport layer; identified by a unique value that allows network layers to identify the connection to its peer.

The elementary component from which a FADU tree is built.

A name used to locate a node that is part of the structuring information contained in a FADU.

To indicate that a request was serviced and its outcome is available. For example, issuing an em_wait call is asking for the event that was noted for the longest period of time.

A set of standards that define the seven layers of communication protocols for a network; ISO defines these standards.

A unit of transmitted data, with a fixed maximum size.

An address used to communicate with other systems and processes; is unique within the network.

The actual Presentation layer data transmitted to the peer Presentation layer.

A formalized set of rules for network communication.

The actual file, including its name and attributes, that is mapped to the VFS.

A collection of actual files, including their names and attributes, that is mapped to the VFS.

The period during which you can call a specific set of FTAM functions; the regime determines the activities that can occur at a given time and therefore, creates the rules (protocols) for the FTAM state machine. (For example, the Data Transfer regime allows reading or writing of the file.) Regimes are nested.

The entity that receives and services an initiator's request; if applicable, the responder returns a response; the responder interacts directly with the virtual filestore.

A constraint set that generates an access structure that
• consists of two levels (levels zero and one),
• may have data units at only the leaf nodes, and
• has no data unit at the root node.

See "Application Entity."

See "Regime."

The number of functions (within a set of grouped functions) that must change regimes for the entire group to be successful.

A diagnostic tool that records specific events on individual HP OSI Transport Services subsystems. Tracing degrades system performance and thus, is not always enabled.

A constraint set that contains a single root node with a data unit; no file structure information is available.

An abstract model for describing files and their attributes, and the possible actions on them; provides a uniform interface to all real file systems.
