Transaction Management Facility (TMF) subsystem
Transaction Management Facility (TMF) subsystem. The major component of the
NonStop TM/MP 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.
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 Tandem 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 Tandem.
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).
