TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)
tell message An informational message sent by PATHCOM or a management application to one or more
terminals controlled by a SCREEN COBOL program, to be displayed for the terminal operators.
TELL object A temporary object used in PATHCOM and SPI commands to define a tell message.
temporary TERM
object
A TERM object created by the PATHMON process when a PATHCOM RUN PROGRAM command
or an SPI START PROG command is issued. Temporary TERM objects are deleted by the PATHMON
process when application processing is completed or when a STOP TERM or ABORT TERM
command is issued. Names of temporary TERM objects begin with a number. See also configured
TERM object and TERM object.
TERM object A definition of a task that uses a SCREEN COBOL program to control an input/output device
such as a terminal or workstation, or an input/output process such as a front-end process. A
TERM object can be either explicitly configured with an ADD command or created by the
PATHMON process through a PATHCOM RUN PROGRAM or SPI START PROG command. TERM
objects created by the latter method are called temporary TERM objects. See also configured
TERM object and temporary TERM object.
terminal An I/O device capable of sending and receiving information over communications lines.
terminal context Data maintained by a TCP for each active terminal under its control.
terminal control
process (TCP)
A process used for terminal management and transaction control, provided by HP as part of the
Pathway/iTS product. A TCP is a multithreaded process that interprets compiled SCREEN COBOL
requester programs (screen programs) in the user’s application, executing the appropriate program
instructions for each I/O device or process the TCP is configured to handle. The TCP coordinates
communication between screen programs and their I/O devices or processes and, with the help
of the PATHMON process, establishes links between screen programs and server processes. See
also requester and SCREEN COBOL.
terminal data area
(TDA)
In SCREEN COBOL, the area that the TCP allocates for terminal context data. The MAXTERMDATA
parameter of the PATHCOM SET TCP command defines the upper limit for this data area.
thaw condition A condition in which prohibition of communication between a terminal and a server class is lifted.
See also freeze condition.
thread A task that is separately dispatched and that represents a sequential flow of control within a
process (for example, a TCP).
throughput The number of transactions a system can process in a given period, such as one second.
TMF See Transaction Management Facility (TMF) subsystem.
TMF level recovery Recovery of the database to a consistent state through the use of the TMF subsystem. When a
failure occurs, the TMF subsystem allows the application to back out the entire transaction, returning
the contents of the database to the values it held when the transaction was started. The application
can then retry the transaction.
TNS See Tandem NonStop Series (TNS).
TNS/R See Tandem NonStop Series/RISC (TNS/R).
token 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.
1.
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 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 NonStop systems.
See also Portable Transaction Application Language (pTAL).
