Overview of FTAM Concepts
NOTE Refer to the “Handling Errors” chapter for information on checking for
errors on synchronous and asynchronous calls. Refer to the “Using
Support Functions” chapter for information on using em_wait( ).
File Attributes
An FTAM file has two distinct parts: its attributes and its contents.
Attributes describe the file (e.g., size, creator), and are either file
attributes or activity attributes:
Document Types
An FTAM document type corresponds to a file type on most systems. In
real filestores, common file types include stream text files,
record-oriented text files, binary files, and directories which contain files.
These file types are represented by the following FTAM document types:
• FTAM-1 Unstructured, stream-oriented text files
• FTAM-2 Record-oriented text files
• FTAM-3 Unstructured, stream-oriented binary files
• INTAP-1 Record files
• NBS-9 Directories, which contain files
For more information on document types, refer to the “Document Types
and Constraint Sets” chapter. For information on setting document
types, refer to the “FTAM Data Structures” chapter.
File
Attributes
Define the file properties that are available to all
initiators. File attributes are stored with the file or
created with the file. File attributes are an inherent
part of the file (e.g., size). Some file attributes identify
structural aspects of the file contents.
Activity
Attributes
Define the properties that exist only while a specific
FTAM connection is being used. These attributes are
not part of the file (e.g., file_store_password).
