transaction backout
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 Remote 
Server Call (RSC) product, that runs on a Tandem 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 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
