NonStop Server for Java 4.2 Programmer's Reference

See Data Control Language (DCL).
DDL
See Data Definition Language (DDL).
debuggee
A process being debugged. The process consists of the application being debugged, the Java VM
running the application, and the Java VM Debug Interface (JVMDI).
debugger
A program designed to use the Java Debugging Interface (JDI) and connect to the (debuggee) so
that a programmer can step through the debuggee process, examine the data, and monitor
conditions such as the values of variables.
deserialization, object
The reverse of Object Serialization.
digital signature
A way of automatically identifying the sender of an electronic message or document, without the
possibility of alteration.
DNS
See Domain Name Server (DNS).
Domain Name Server (DNS)
An HP 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
SQL/MP. The NonStop Server for Java 4 has these driver implementations: JDBC Driver for
SQL/MP (JDBC/MP) and JDBC Driver for SQL/MX (JDBC/MX).
E
Enscribe
HP 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 NonStop 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.
