token
token. (1) An attribute control element in the CONTROLLED clause of a SCREEN COBOL
program, which allows run-time control of display attributes. This token consists of an
attribute identifier and an attribute value. (2) In the Subsystem Programmatic Interface
(SPI), a distinguishable unit in a message. An SPI token consists of an identifier (token
code or token map) and a token value. Programs place tokens in an SPI buffer by
calling the SSPUT procedure and retrieve them from the buffer by using the SSGET
procedure.
transaction. An operation or a series of operations that retrieves and updates information to
reflect an exchange of goods or services. In the process of retrieving and updating
information, a transaction transforms a database from one consistent state to another.
The TMF subsystem treats a transaction as a single unit; either all of the changes
made by a transaction are made permanent (the transaction is committed) or none of
the changes are made permanent (the transaction is aborted).
Transaction Application Language (TAL). A systems programming language with many
features specific to stack-oriented Tandem NonStop systems. See also pTAL.
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.
