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

static server A server process that the PATHMON process creates when a START SERVER command is issued.
The PATHMON process starts the number of static servers defined by the NUMSTATIC attribute
for the server class. See also dynamic server.
Structured Query
Language (SQL)
A relational database language used to define, manipulate, and control databases.
subsystem In the context of the Subsystem Programmatic Interface (SPI) and the Event Management Service
(EMS), a process or collection of processes that gives users access to a set of related resources
or services. A subsystem typically controls a cohesive set of objects. The Pathway subsystem
includes PATHMON processes, TCPs, and all other components of the PATHMON environment.
subsystem ID In management applications, a data structure that uniquely identifies a subsystem. The subsystem
ID is specified in SPI commands to identify the target subsystem, and in EMS event messages to
identify the source of the event message. The Pathway subsystem ID applies to all components
of the PATHMON environment, including PATHMON processes and TCPs.
Subsystem
Programmatic
Interface (SPI)
A set of Guardian procedures, message formats, and definition files that allows management
applications to communicate directly with subsystem processes, such as the PATHMON process,
for configuration and control of objects and for event management.
subtype 30 process A nonprivileged process that simulates terminals and communications devices.
subvolume A related set of files, as defined by the user, within the Guardian environment. The name of a
subvolume is the third of the four parts of a file name.
swap file A temporary file created by a process for temporary storage: for example, by the Kernel Managed
Swap Facility (KMSF) on behalf of a TCP for temporary storage of terminal context.
sync ID A value used in the Guardian environment to determine whether an I/O operation has finished.
In active backup programming, a file’s sync ID is used to prevent the backup process from
repeating I/O operations that have already been completed by the primary process.
syncdepth A parameter to Guardian procedure calls that sets the maximum number of operations or messages
that a process is allowed to queue before action must be taken or a reply must be performed.
system name The first of the four parts of a Guardian file name; also called a node name.1.
2. A name that identifies the NonStop system on which a PATHMON process is running. In
SCREEN COBOL programs, this name is given in SEND statements.
3. A SCREEN COBOL word that identifies part of the NonStop operating environment; a name
can be associated with function keys or terminal display attributes.
System/T The transaction monitor for a NonStop Tuxedo system. See also NonStop Tuxedo application.
TACL See Tandem Advanced Command Language (TACL).
TAL See Transaction Application Language (TAL).
Tandem Alliance HP’s marketing and technical support program for third-party vendors, which encourages the
development of application software for the Pathway environment. The Alliance attracts software
developers, value-added resellers, and other vendors who can provide industry-specific and
general business applications for NonStop customers.
Tandem NonStop
Series (TNS)
Computers provided by HP that support the NonStop Kernel and that are based on complex
instruction-set computing (CISC) technology. TNS processors implement the TNS instruction set.
See also complex instruction-set computing (CISC) and Tandem NonStop Series/RISC (TNS/R).
Tandem NonStop
Series/RISC
(TNS/R)
Computers provided by HP that support the NonStop Kernel and that are based on reduced
instruction-set computing (RISC) technology. TNS/R processors implement the RISC instruction set
and are upwardly compatible with the TNS system-level architecture. See also reduced
instruction-set computing (RISC) and Tandem NonStop Series (TNS).
task The sequence of SCREEN COBOL program units that are executed as a result of a PATHCOM
START TERM or RUN PROGRAM command or an SPI START TERM or START PROG command.
TCLPROG file A SCREEN COBOL object library file.
TCP See terminal control process (TCP).
TDA See terminal data area (TDA).
TEDIT An HP text editor used to create or modify a source text file. Also called PS Text Edit.
