NonStop Server for Java 6.0 Programmer's Reference

command The operation demanded by an operator or program; a demand for action by, or information
from, a subsystem. A command is typically conveyed as an interprocess message from a program
to a subsystem.
Common Gateway
Interface (CGI)
The World Wide Web standard interface for servers , often written in C . The NonStop Server
for Java 6.0 supports CGI-like use of Java using servlets with iTP Secure WebServer . See also
Pathway CGI.
Common Object
Request Broker
Architecture
(CORBA)
The OMG standard that allows objects that adhere to it to interact over a network regardless of
the types of machines or operating systems on which they reside. Java interoperates with this
standard using Java IDL and JTS .
Compiler (C3) A JVM Hotspot Compiler back-end for application performance.
concurrency A condition in which two or more transactions act on the same record in a database at the same
time. To process a transaction, a program must assume that its input from the database is consistent,
regardless of any concurrent changes being made to the database. TMF manages concurrent
transactions through concurrency control .
concurrency
control
Protection of a database record from concurrent access by more than one process. TMF imposes
this control by dynamically locking and unlocking affected records to ensure that only one
transaction at a time accesses those records.
conformant A Java implementation is conformant if it passes all the tests for Java SE 6.
CORBA See Common Object Request Broker Architecture (CORBA).
Core Packages The required set of APIs in a Java platform edition which must be supported in any and all
compatible implementations.
D
Data Control
Language (DCL)
The set of data control statements within the SQL language.
Data Definition
Language (DDL)
A language that defines all attributes and properties of a database, especially record layouts,
field definitions, key fields, field locations, file locations, and storage strategy.
DCL See Data Control Language (DCL).
DDL See Data Definition Language (DDL).
debuggee A process being debugged. The process consists of the application being debugged and the
Java VM running the application.
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 NonStop SQL/MX . The NonStop Server for Java 6.0 has these driver implementations: JDBC
Driver for SQL/MP(JDBC/MP) and JDBC Driver for SQL/MX (JDBC/MX) .
E-F
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
