CORBA 2.3 Glossary (NonStop CORBA 2.3.7+)
example, NonStop TS/MP offers a management programming interface that gives applications
access to the same set of functions available through PATHCOM.

TCP/IP (Transmission Control Protocol/Internet Protocol)
One of the most widespread networking protocols, the basis for communications on the Internet.
The CORBA IIOP protocol uses TCP/IP as its transport service. NonStop TCP/IP is the HP
product that implements TCP/IP on NonStop systems.
thread
The basic unit of program execution. A process can have several threads running concurrently,
each performing a different job, such as waiting for events or performing a time-consuming job
that the program doesn't need to complete before going on. When a thread has finished its job, the
thread is suspended or destroyed.
Threads differ from server pools in that threads require the same process to handle multiple
requests, whereas server pools allow requests to be handled by different processes running in
parallel.
thread-blocking operation
Operations that block only the calling thread, rather than the entire process, while they are in
progress. Examples are nowait file I/O operations and operations directed to distributed objects.
thread-safe code
Code in a multithreaded program that protects an object from access by more than one thread at a
time. Mechanisms to provide thread-safe code include mutexes in C++ and monitors in Java.
three-tiered architecture
See tiered application architecture.
tiered application architecture
An application model in which function is divided into a few major categories of objects, such as
interface, control, and entity objects.
TMF
See Transaction Management Facility (TMF).
Tool Command Language (TCL)
The Command Line Interface used in cfgmgt. TCL provides a wide variety of services and is a
powerful aid for development, testing, and deployment.
trace
A sequential record of data or program flow, useful for troubleshooting. NonStop CORBA
includes facilities to trace the flow of control within an application.
