NonStop Server for Java (NSJ) Programmer's Guide (NSJ 2.1+)
See Domain Name Server (DNS).
Domain Name Server (DNS)
A Compaq product, part of TCP/IP, that provides the facilities for the maintenance and
automated distribution of network resource name information. DNS permits decentralized
administration of resource names and specifies redundancy of servers to provide a
reliable query service for users.
driver
A class in JDBC that implements a connection to a particular database management
system such as NonStop SQL/MP. NonStop Java includes drivers for SQL/MP and
SQL/MX.
DriverManager
The JDBC class that manages drivers.
DSM/SCM
See Distributed Systems Management/Software Configuration Manager (DSM/SCM).
E
Enscribe
Compaq database management software that provides a record-at-a-time interface
between servers and a database. As an integral part of the 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 Compaq system can be Enscribe files,
SQL/MP tables, or SQL/MX 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.
Expand
The NonStop Kernel operating system network that extends the concept of fault tolerance
to networks of geographically distributed Compaq systems. If the network is properly
designed, communication paths are constantly available even if there is a single line
failure or component failure.
expandability
See scalability.
