CORBA 2.6.1 Glossary

A Java function. An operation defined for an object, implemented as a procedure or function in a
programming language. The calling sequence for a method is called a method signature. A call to a
method is called a method invocation.
multi-tiered architecture
See tiered application architecture.
name binding
Also known as name-object binding. An object consisting of a name and a binding.
name component
A structure containing a name-id string and a name-kind string.
naming context
An object that contains a set of name bindings in which each name is unique. To resolve a name is
to determine the object associated with the name in a given context.
Naming Service
A standard application service (one of the OMG Common Object Services) for storing object
names, identifiers, and possibly other information. One important use of the Naming Service is to
store the names of factory objects to use in creating other objects. See also ns_browse.
narrowing
A term used in CORBA when moving from a base interface to a derived interface. Java refers to
this action as downcasting.
nested transactions
Transactions that begin and end within another transaction.
network client
A client process that resides on some other system (not the same NonStop system or Expand
network as the NonStop CORBA ORB). The network client process acts as a CORBA client.
Network clients send IIOP requests for the services of an application through the NonStop
CORBA communication services. Also referred to as a remote client.
NonStop CORBA event framework
The core of the NonStop CORBA run-time environment, which supports the handling of I/O
events over various transport protocols. It provides APIs that are used internally by NonStop
CORBA but can also be used in legacy server wrapper and legacy client wrapper programs. It is a
low-level mechanism that does not require (but does enable) both communicating components to
use CORBA.
NonStop Distributed Component Console
A tool that allows you to manage NonStop CORBA domains and services.
NonStop DOM/MP (NonStop" DOM)
A component of NonStop CORBA that implements a C++ programming environment. NonStop
