CORBA 2.6.1 Glossary

concurrency
Simultaneous operation. This term can apply to processes running in parallel, simultaneous
transactions, or multiple clients using the same object (or other resource) at the same time.
concurrency service
An application service that manages simultaneous access to objects by multiple clients, primarily
by supporting read-locking and write-locking requests.
configuration database
A database that stores execution information such as program profiles and operating information
needed by NonStop CORBA services. The database is dynamically maintained, and it may be
changed by users of the NonStop Distributed Component Console, the configuration management
tool, or by CORBA servers.
constructor
A method that creates an object. In the C++ and Java languages, constructors are instance methods
that have the same name as their class. Constructors are invoked by using the new keyword.
container
A specialized component that contains and manages other components.
control object
A type of object that coordinates other objects, for example, to perform transactions on a set of
objects that represent stored data.
CORBA
See Common Object Request Broker Architecture.
CORBA object
An object abstraction, defined using an IDL interface, to which client requests are directed. A
CORBA object can be located by its reference. Exactly how the CORBA object satisfies a request
is transparent to the client.
CORBAServices
See Common Object Services.
COS
See Common Object Services.
CSMAP
The NonStop CORBA database whose entries determine which Comm Server (CS) each
configured client will use. Entities in the configuration database that hold CS load mappings
between remote clients and client/servers.
Current interface
An object class, defined by the Object Transaction Service (OTS), which gives the OTS client
