Glossary-24
subtype 30 process
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.
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.
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.
system name. (1) The first of the four parts of a Guardian file name; also called a node name.
(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.
