TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

transaction
backout
A TMF subsystem activity in which the effects of a partially completed transaction are canceled.
Transaction
Delivery Process
(TDP)
A multithreaded gateway process, part of the RSC/MP product, that runs on a NonStop system.
The TDP can be replicated and can manage many connections and workstations at one time, as
well as multiple sessions from each workstation.
transaction
identifier
A unique name that the TMF subsystem assigns to a transaction.
transaction log See audit trail.
transaction
management
The ability to coordinate transaction control functions, such as beginning and ending transactions,
committing or aborting transactions, and recovering transactions.
transaction mode The operating mode of a requester program between the execution of a BEGINTRANSACTION
procedure call or statement and the execution of the associated ENDTRANSACTION or
ABORTTRANSACTION call or statement.
transaction
processing
See online transaction processing (OLTP).
transaction
workload
The number of transactions to be processed by an online transaction processing application.
TRANSFER delivery
system
An information delivery system that enables organizations to move and manage information
efficiently within a single NonStop system or across a network of systems. The TRANSFER delivery
system supports communications between users, I/O devices, and processes in the Guardian
environment.
TSCODE The object code for the part of a GDSX process that is supplied by HP. TSCODE includes generic
routines and services that support the development of a multithreaded, fault-tolerant front-end
process. See also USCODE and Extended General Device Support (GDSX).
tuning The process by which a system manager allocates and balances resources for optimum system
performance.
UMP See unsolicited-message processing (UMP).
unsolicited
message
A message that is sent to a SCREEN COBOL program and includes application-dependent
information to be processed by the program. Although the program does not do anything to
initiate the message, the message must conform to the format defined by the program. The message
is sent first to the TCP. It contains a header with information that is used by the TCP and a body
with information that the TCP delivers to the SCREEN COBOL program.
unsolicited-message processing (UMP)
The feature that allows terminals running SCREEN COBOL requesters to accept and reply to
unsolicited messages sent to them by Guardian processes outside of the PATHMON environment.
USCODE The object code for the part of a GDSX process that is developed by the user to provide device
or access-method specifics such as control operations or data-stream translation. USCODE is
bound with TSCODE to produce an operational GDSX process. See also TSCODE and Extended
General Device Support (GDSX).
user conversion
procedure
A procedure that lets users make their own validation checks or conversions of data passed
between a SCREEN COBOL program and a terminal screen or intelligent device.
ViewPoint
application
An extensible interactive application for managing operations in the Guardian environment. It
provides tools for interacting with multiple NonStop subsystems, including PATHCOM, allowing
a system manager to easily control an integrated NonStop system from one location.
volume A disk drive, or a pair of disk drives that forms a mirrored disk, in the Guardian environment.
The name of a volume is the second of the four parts of a file name.
