CORBA 2.3 Glossary (NonStop CORBA 2.3.7+)

A protocol that provides operations for resolving an initial object reference and for listing the
supported initial reference ids.
business domain
A collection of related business application processes, configuration data, and NonStop" services
for CORBA.
cast
To assign a value of one type to a variable of another type. An instance of a class can be cast to an
instance of another class if the latter is a subclass of the former or if an interface implements the
former.
child class
An object class that inherits characteristics from another class.
class data
Variables that apply, not to a specific object instance, but to an object class as a whole; for
example, a variable that reports the number of instances of a class.
CLI
See Command Line Interface.
client
In object technology, an application component that makes requests of an object. More generally,
an application component that makes requests of a server.
client event handler
An object defined by the NonStop CORBA event framework to support asynchronous
communication between a NonStop CORBA client and a server that uses other technology.
NonStop CORBA provides various types of client event-handler objects to support transport
functions such as I/O completions and error handling. Client event handlers are used in legacy
server wrappers.
client event handler user
An object, defined by the NonStop CORBA event framework, that uses the services of a client
event handler. A legacy server wrapper typically acts as a client event-handler user.
client/server computing
A style of application in which function is divided between a client, which makes requests on
behalf of a user, and a server, which executes those requests. In many cases, the client runs on a
workstation and the server runs on a larger server machine, but this pattern of distribution is not a
necessary characteristic of client/server computing.
Comm Server
A NonStop CORBA process that manages the linkage between remote clients and local servers. A
configuration can have multiple Comm Servers, and many clients can use the same Comm Server.
