NonStop Server for Java Programmer's Reference (NSJ 4.2+)
A software process, hardware device, or combination of the two that requests services
from a server. Often, the client is a process residing on a programmable workstation and
is the part of a program that provides the user interface. The workstation client might also
perform other portions of the program logic. Also called a requester.
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 4 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.
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 in the Java 2 SDK, Standard
Edition.
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.
CyberWeb
