CORBA 2.6.1 Glossary

server selection
The process of choosing a server process to handle a request. In NonStop CORBA stateless
processing, each request can be handled by any server that can host the object interface. In stateful
processing, a specific server is chosen to handle all of a series of requests.
service
A set of related functions available to applications on a system or network. See also Common
Object Services.
setting
In general, the value of a parameter or variable. In NonStop CORBA, a value specified in a
configuration file.
shared runtime library (SRL)
An object file that the operating system links to a program at runtime.
showior
A tool that produces output that can be used to track down problems in NonStop CORBA
configurations.
skeleton
Entity residing on the server. A skeleton is a base class containing pointers to servant methods.
The base class is generated by the IDL compiler. The skeleton connects the servant to an object
adapter.
slot
The portable interceptors PICurrent interface is a slot table. The slots are used by each service
to transfer context data between the service's context and the requestor's or reply's service context.
Each service that wishes to use PICurrent reserves a slot or slots at initialization time.
socket
A logical connection to the TCP/IP process.
SSLIOP
Secure Sockets Layer Inter-ORB Protocol. SSLIOP is the NonStop CORBA implementation of
IIOP over Secure Sockets Layer.
stateful processing
A style of application logic in which all operations directed to the same object (for the duration of
a link acquired by the client) must be handled by the same servant. Operations directed to other
objects in the class can be handled by different servants in other processes. A stateful object can
maintain state information (data associated with a particular object instance) in memory between
operations, because all requests for that reference go to the same instance. With stateful objects, a
client's object must always reference the specific instance of that object. Stateful objects are
created by a POA whose lifespan policy is TRANSIENT, such as the root POA, or by explicitly
setting the NonStop CORBA proprietary state policy to STATEFUL. Stateful processing is the
