Kernel Group File Attributes
The responder allows for the simplification of FTAM-2 document types to FTAM-1
document types only. In addition, FTAM-2 simplification is allowed only on Compaq
Enscribe relative files, not on SQL tables. Per the ISO 8571-2 provisions, the responder
allows no simplification of FTAM-1 or FTAM-3 files.
Compaq FTAM does not permit the relaxation of document type parameters to less
restrictive values. The VFS component of the responder keeps no record of the
universal-class value associated with files created on the Guardian file system. In the
case of the maximum-string-length parameter, the VFS records the maximum-string-
length value for all FTAM-2 documents, and for FTAM-3 documents with a string-
significance value of fixed or variable. For FTAM-1 documents, and for FTAM-3
documents with a string-significance value of not significant, the VFS has no memory of
the associated maximum-string-length value.
Table 4-9 shows the simplification of document types that the responder allows.
NBS-9 Documents
NBS-9 documents are files that have been created by listing Guardian directories. If the
remote initiator sends an F-SELECT primitive with a filename attribute of DIRLIS (all
in uppercase), the Compaq responder returns a file of directory entries (an NBS-9 file)
for the volume and subvolume specified in the filename attribute. The read and read-
attribute actions are the only file actions that you can perform on an NBS-9 file. If a
volume and subvolume are not specified, the responder uses the default volume and
subvolume of the user specified in the initiator-identity parameter of the F-INITIALIZE
request.
