TS/MP 2.5 Pathsend and Server Programming Manual

file-name
expansion
The expansion of a partially qualified Guardian file name for a disk file to include the associated
node, volume, and subvolume names.
fixed-function
terminal
A nonintelligent device (that is, a device without processing ability) capable of sending and
receiving information over communications lines. Fixed-function terminals are often referred to
as dumb terminals.
freeze condition A condition in which communication between a terminal and a server-class is prohibited. See
also thaw condition.
front-end process A process, such as the process that accepts the TCP terminal-data stream, that serves as the
intermediary between one system, process, or device and another.
fully qualified file
name
The complete name of a file in the Guardian environment. For a permanent disk file, this consists
of a node name (system name), volume name, subvolume name, and file identifier (file ID). In
interactive interfaces such as PATHCOM and TACL, the parts of a file name are separated by
periods. See also partially qualified file name.
gateway process A process, such as the Transaction Delivery Process (TDP) that is part of RSC/MP, that manages
communications between dissimilar environments (for example, a workstation and a NonStop
system). A gateway process both transfers information and converts it to a form compatible with
the protocols used by the destination environment.
GDSX See Extended General Device Support (GDSX).
Graphical User
Interface (GUI)
A type of screen interface that typically includes pull-down menus, icons, dialog boxes, and online
help.
Guardian An environment available for interactive or programmatic use with the NonStop Kernel. Processes
that run in the Guardian environment use the Guardian system procedure calls as their application
program interface, and might also use related APIs such as the Pathsend and TMF procedure
calls. See also Open System Services (OSS).
Guardian
environment
The Guardian API, tools, and utilities. See also Guardian.
Guardian
operating
environment
See Guardian environment.
high PIN A process identification number (PIN) in the range 256 through 65535. See also process
identification number (PIN) and low PIN.
HP NonStop
Remote Server
Call/MP (RSC/MP)
An HP software product that facilitates client/server computing, allowing personal computer (PC)
or workstation applications running under Microsoft Windows software or the MS-DOS or OS/2
operating system to access Pathway server-classes and Guardian processes. Transactions are
transmitted from the PC or workstation application (the client) to a Pathway application running
on a NonStop server by means of a supported communications protocol, such as NETBIOS,
TCP/IP, or an asynchronous connection.
HP NonStop
Transaction
Management
Facility (TMF)
subsystem
The major component of the TMF product, which protects databases in online transaction
processing environments. To furnish this service, the TMF subsystem manages database
transactions, keeps track of database activity through audit trails, and provides database recovery
methods. See also NonStop Transaction Manager/MP (NonStop TM/MP) and transaction.
HP NonStop
Transaction
Manager/MP
(NonStop TM/MP)
An HP software product that provides transaction management, transaction protection, and
database consistency in online transaction processing (OLTP) environments. It gives full protection
to transactions that access NonStop SQL/MP and Enscribe databases, as well as recovery
capabilities for transactions, online disk volumes, and entire databases. The component of NonStop
TM/MP that provides these features is the TMF subsystem. See also Transaction Management
Facility (TMF) subsystem.
HP NonStop
TS/MP
A HP product that provides process management and link management functions for OLTP
applications on NonStop systems. TS/MP consists of the PATHMON process, the ACS Subsystem
process, the PATHCOM process and interface, and the Pathsend procedures. Together with TMF,
TS/MP forms the foundation for the open transaction processing services of HP, including those
provided by the RSC/MP and POET products and the NonStop Tuxedo system. See also
Pathway/iTS and NonStop Transaction Manager/MP (NonStop TM/MP).
