Glossary-6
(FUP) commands, and generates object-definition source code in a variety of
programming languages.
default user (DEFUSER). An attribute of a Compaq virtual filestore (VFS) profile that
allows access to files in the Compaq responder’s VFS in cases where the initiator
identity and filestore password are not provided when an association is established. The
default user specifies the default Guardian user ID and password to be used.
diagnostic parameter. An optional parameter providing information that qualifies the
success or explains the failure of a requested FTM procedure call. For applications
using the FTAM API, this parameter primarily returns whatever diagnostic messages
have been received from the remote responder or the local initiator. In addition, you
can use this parameter to send diagnostic messages to a remote responder using the
FTM_CANCEL_REQ_ , FTM_DATA_END_REQ_ , and FTM_U_ABORT_REQ_
procedures. See also ISO FTAM diagnostic messages.
Distributed Systems Management. See DSM.
distributor. An EMS process that distributes event messages from event logs to
requesting management applications, to Compaq NonStop Kernel destinations, or to a
collector. Contrast collector.
document type. An FTAM definition, defining the structure of and method of access to
a file. Compaq FTAM supports four document types: FTAM-1, FTAM-2, FTAM-3, and
NBS-9. An FTAM-1 document is an unstructured text file that cannot be broken into
smaller segments by the protocol. An FTAM-2 document is a structured text file
divided into FADUs, which cannot be broken down. An FTAM-3 document is an
unstructured binary file. An NBS-9 document is a read-only directory as defined by the
NIST FTAM Phase 2 agreements.
DSM (Distributed Systems Management). A set of tools provided by Compaq to
manage NonStop systems, Expand networks, and Compaq communications products.
These tools include the ViewPoint console application, the Subsystem Control Facility
(SCF) for data communications subsystems, the Subsystem Programmatic Interface
(SPI), the Event Management Service (EMS), the PTrace (print trace) utility, token-
oriented programmatic interfaces to the management processes for various Compaq
subsystems, and other products.
EMS (Event Management Service). A facility provided by Compaq for event
collection, event logging, and event distribution on Compaq NonStop systems. It
includes different forms of event description for interactive and programmatic
interfaces, lets an operator or application select specific event-message data, and allows
for flexible distribution of event messages within a system or network. The FTAM and
APLMGR subsystems generate event messages that are displayed as operator messages;
however, the programmatic interface to FTAM and APLMGR event messages is not
available for customer use. See also event message.
end-of-file marker. See EOF.
enhanced-file-management functional unit. A functional unit that adds the
modification of file attributes to the capabilities of the limited-file-management
functional unit. See limited-file-management functional unit.
