Enscribe
Compaq database management software that provides a record-at-a-time interface
between servers and a database. As an integral part of the NonStop
TM
operating system
distributed across two or more processors, Enscribe helps ensure data integrity if a
processor module, I/O channel, or disk drive fails. Files on a NonStop
TM
system can be
either Enscribe files or SQL/MP tables. Enscribe files can be either structured or
unstructured.
exception
An event during program execution that prevents the program from continuing normally;
generally, an error. Java methods raise exceptions using the throw keyword and handle
exceptions using try, catch, and finally blocks.

The NonStop
TM
Kernel operating system network that extends the concept of fault
tolerance to networks of geographically distributed NonStop
TM
systems. If the network is
properly designed, communication paths are constantly available even if there is a single
line failure or component failure.

See scalability.
F
fault tolerance
The ability of a computer system to continue processing during and after a single fault
(the failure of a system component) without the loss of data or function.
