Glossary
NOTE: This glossary does not include terms for elements of the SCREEN COBOL
language that are also found in standard COBOL. For definitions of such terms, refer to
standard COBOL texts or to the text of the Pathway/TS SCREEN COBOL Reference
Manual.
$RECEIVE A special Guardian file name through which a process receives and optionally replies to messages
from other processes by using Guardian procedure calls. This file is analogous to a request queue
defined for a NonStop TUXEDO server.
absolute pathname An OSS pathname that begins with a slash (/) character and is resolved beginning with the root
directory. See also OSS pathname, relative pathname, and root directory.
accept operation An operation in which a screen program waits for a response from the terminal and allows data
to be input into the program data area from the terminal.
advisory message A message displayed in the terminal advisory field to inform the terminal operator of errors
detected during input checking.
API See application program interface (API).
application A complete set of programs or routines that perform a function. See also Pathway application,
NonStop TUXEDO application, and PTP application.
Application Cluster
Services (ACS)
subsystem
An infrastructure used by transaction processing middleware products to manage and access
server classes.
Application Cluster
Services(ACS)
domain
A defined set of objects (resources) within a single physical NonStop system that are controlled
and managed as a unit by the ACS subsystem.
application
program interface
(API)
A set of services (such as programming language functions or procedures) that are called by an
application program to communicate with other software components. For example, an API might
consist of a set of procedure calls that provide a workstation application with a standard interface
for communicating with a Tandem system. Other examples of APIs are the ATMI in Novell TUXEDO
systems and NonStop TUXEDO systems, the Customer Information Control System (CICS)
command-level API, and the Pathsend procedures.
application
terminal
A terminal on which a Pathway application runs. See also command terminal.
Application-Transaction Monitor Interface (ATMI)
The application programming interface to the System/T transaction monitor in a NonStop TUXEDO
system. This interface includes transaction routines, message handling routines, service interface
routines, and buffer-management routines.
assignment The use of an ASSIGN command to make logical file assignments for programs in the Guardian
environment. A logical assignment equates a Tandem file name with a logical file of a program
and, optionally, attributes characteristics to that file.
associative server A process within a server class that can be started outside the Pathway environment by a process
other than the PATHMON process that controls the server class.
ATMI See Application-Transaction Monitor Interface (ATMI).
attributes Those characteristics of an object that influence the operation of that object and establish its
capabilities.
audit trail A record of database changes that can be used by the TMF subsystem to rebuild a database in
the event of a hardware or software failure. An audit trail is also known in the industry as a
transaction log.
audited file A database file that is flagged for auditing by the TMF subsystem; auditing is the monitoring of
transactions in preparation for recovery efforts.
