TS/MP 2.5 System Management Manual

special register A data item defined by the SCREEN COBOL compiler, rather than explicitly in the program. Each
special register has a particular purpose and must be used only as defined. The SCREEN COBOL
language defines a different set of special registers from those defined by the standard COBOL
language.
SPI See Subsystem Programmatic Interface (SPI).
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 Tandem 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 Tandem 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 Advanced
Command
Language (TACL)
The user interface to the Tandem NonStop Kernel in the Guardian environment. The TACL product
is both a command interpreter and a command language.
Tandem Alliance Tandem’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 Tandem customers.
Tandem NonStop
Kernel
The operating system for Tandem NonStop systems. The operating system does not include any
application program interfaces.
Tandem NonStop
Series (TNS)
Tandem computers that support the Tandem 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).
