TSM Service Application
TSM Service Application. A component of the TSM client software. The TSM Service
Application enables you to communicate with a NonStop S-series server when the
NonStop operating system is running. When the operating system is not running,
communication must take place using the TSM Low-Level Link Application. See also
TSM Low-Level Link Application
.
TSM workstation. A PC-compatible workstation on which the TSM client software is
running. The TSM workstations configured as the primary and backup dial-out points
are referred to as the primary and backup system consoles.
TTE. See tape drive
.
UCME. See uncorrectable memory error (UCME)
.
unattended site. A computer environment where there is no operator residing on site and the
only access is from a central monitoring station.
uncorrectable memory error (UCME). An error caused by incorrect data at a particular
memory location. The cause of the error is such that the error is not automatically
corrected by the system, and memory replacement is required. Contrast with correctable
memory error (CME).
uninterruptible power source (UPS). A source of power, external to the system, capable of
supplying continuous power to a system in the event of a power failure.
unplanned outage. Time during which a NonStop system is not capable of doing useful
work because of an unplanned interruption. Unplanned interruptions can include failures
caused by faulty hardware, operator error, or disaster.
UPS. See uninterruptible power source (UPS)
.
upward compatibility. The ability of a requester to operate with a server of a later revision
level. In this case, the requester is upward-compatible with the server and the server is
downward-compatible with the requester. Contrast with downward compatibility
.
WAN. See wide area network (WAN)
.
WANBoot process. A process provided as part of the wide area network (WAN) subsystem
that implements the BOOTP protocol and provides management functions to the WAN
subsystem and the WAN products.
WAN concentrator. See ServerNet wide area network (SWAN) concentrator
.
WAN shared driver. A driver, provided as part of the wide area network (WAN) subsystem,
that provides a simplified interface to Transmission Control Protocol over Internet
Protocol (TCP/IP) for use by I/O processes. The shared driver interface is similar to that
provided by DOIOPLEASE on earlier NonStop systems.
WAN subsystem. See wide area network (WAN) subsystem
