associative server
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.
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.
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.
availability. The amount of time an application running on a Tandem system can be used
effectively by a user of that application.
backup process. The member of a process pair that takes over the application work when
the primary process fails. See also primary process, process pair, and checkpoint
message.
base screen. In SCREEN COBOL, a screen that occupies the entire physical display area
of a terminal and can be displayed independently of other screens. This type of screen
can contain areas on which overlay screens are displayed. See also screen and
overlay screen.
batch processing. A method of transaction processing in which transactions are first
grouped together and then processed at regular intervals. See also online transaction

cascading server. A term formerly used for a nested server. See nested server.
checkpoint message. In the Guardian environment, a message sent by a primary process
to its backup process that keeps the backup process up to date on the state of the

used in the event of a takeover by a backup process to allow the backup process to
maintain fault-tolerant operation.
CICS. See Customer Information Control System (CICS).
