Tandem Network Statistics Extended (NSX).
documents that are available on local CD-ROM discs as well as online, Internet-
accessible servers. This common interface allows you to merge local and online searches
and display local and online windows.
Tandem Network Statistics Extended (NSX). A network management tool that provides
operators with a global perspective on the entire network. With NSX, operators can
collect and monitor up-to-the-moment performance statistics on all nodes, processors,
and Expand line handlers in the network.
Tandem NonStop Kernel. The operating system for NonStop systems, which consists of the
core and system services. The operating system does not include any application
program interface.
Tandem Object Monitoring Facility (OMF). A Tandem product that enables operators to
supervise objects such as processors, disks, files, and processes within the Tandem
environment.
Tandem Performance Data Collector (TPDC). A Tandem host-based performance-data-
collection product.
Tandem Reload Analyzer. A Tandem product used to identify fragmented Enscribe files and
NonStop SQL/MP tables and to determine the files and tables that will benefit from an
online reorganization.
Tandem Service Management. A client/server application that provides troubleshooting,
maintenance, and service tools for the Himalaya S-series server. Tandem Service
Management (TSM) consists of software components that run on the Himalaya S-series
server and on a PC-compatible workstation. TSM combines many of the system
maintenance functions provided on D-series releases by the Syshealth toolkit, the
Tandem Maintenance and Diagnostic Subsystem (TMDS), and the Remote Maintenance
Interface (RMI) product.
TCM. See Tandem Capacity Model (TCM).
TCP. See Terminal control process (TCP).
TERM. A task that uses a screen program to control input and output devices (such as
terminals or workstations) or input and output processes (such as front-end processes).
Each task runs as a thread in a terminal control process (TCP), which can handle many
such tasks concurrently.
Terminal control process (TCP). A multithreaded process supplied with Pathway/TS that
interprets and executes screen program instructions for each input-output (I/O) device or
process the TCP is configured to handle. The TCP coordinates communication between
screen programs and their I/O devices or processes and, with the help of the PATHMON
process, establishes links between screen programs and Pathway server processes.
TFDS. See Tandem Failure Data System (TFDS).
third-party backup site. A backup site leased from a third party.
