adapter activator
A server-side object used by the ORB when a request is made for a child POA that does not exist.
In such a case, the adapter activator creates the child POA.
admin DB
The database that stores the operational data used by the NSDAdminServer and
NSDEnvironServer processes. The location of the database is given by the environment variable
NSDOM_ADMIN_DB.
AdminServer
See NSDAdminServer.
attribute
An identifiable association between an object and a value. An attribute A is made visible to clients
as a pair of operations: get_A and set_A. Read-only attributes generate only get operations. An
attribute is a characteristic or property of an object, and it is typically implemented as a simple
data member or as an association with another object or group of objects.
authentication
The verification of a claimants entitlement to use a claimed identity and/or privilege set.
Authentication is encryptions complement. While encryption ensures against eavesdroppers,
authentication ensures against imposters. Often, it is not enough to ensure that only its intended
receiver can read a message; there must also be a way to verify that the sender of a message is in
fact who he or she says they are.
availability
Continuous service. NonStop systems are designed to provide high availability.
base class
A class from which some other class (a subclass) is derived, so that the subclass inherits
characteristics from the base class and may also define characteristics of its own.
Basic Object Adapter (BOA)
An early object adapter that was replaced by the Portable Object Adapter (POA). NonStop
CORBA supports the POA only.
