Introduction to TRANSFER Delivery System—109426 Glossary-5
Server. Part of an application that deals with the database, handling everything related to the
application computations and database access.
Server class. A grouping of duplicate copies of a single server program; server processes
within the class have identical attributes.
Server process. A process that implements application requests and sends replies to the
requester; synonymous with Server.
Session. The period between the time a correspondent logs on and begins communicating
with TRANSFER and the time the correspondent logs off and ends that communication.
A correspondent can have multiple sessions.
System administrator. A correspondent who is responsible for managing TRANSFER
objects. Each node has at least one system administrator.
System manager. The person who is responsible for initializing, monitoring, and controlling
TRANSFER at the local node.
TAL (Transaction Application Language). The language that is used to write Tandem
system software and routines that support transaction-oriented applications.
TCP. See Terminal control process.
Terminal control process (TCP). A PATHWAY process that interprets and executes
SCREEN COBOL programs. It coordinates communication between the SCREEN
COBOL programs, their input-output devices or processes, and the server processes.
TMANAGER. A Tandem application to help system managers monitor and manage their
TRANSFER delivery systems. TMANAGER can be accessed through ADMIN or run
as a standalone PATHWAY program.
TMF transaction. A series of related actions; all actions must occur—or none must occur—
for the database to be consistent.
Transaction Monitoring Facility (TMF). A database protection subsystem incorporated into
the GUARDIAN 90 operating system. TMF maintains the consistency and integrity of a
distributed database that is updated by concurrent transactions; it also provides the tools
for database recovery.
TRANSFER application. A set of processes that communicate with each other and with
TRANSFER, working together to perform a common task.
TRANSFER asynchronous process. A process that schedules packages for delivery, routes
packages to the appropriate recipients, and delivers packages within the time specified
by the sender.
TRANSFER database. A set of internal files that contain information related to local
correspondents and packages in transit. The database is completely controlled by
TRANSFER.
