thread A task that is separately dispatched and that represents a sequential flow of control within a
process.
threads The nonnative thread package that is shipped with Sun Microsystems Java SE 6.0.
throw Java keyword used to raise an exception.
throws Java keyword used to define the exceptions that a method can raise.
TMF See HP NonStop Transaction Management Facility (TMF)
TNS/E The hardware platform based on the Intel® Itanium® architecture and the HP NonStop operating
system, and the software specific to that platform. All code is PIC (position independent code).
TNS/R The hardware platform based on the MIPS™ architecture and the HP NonStop operating system,
and the software specific to that platform. Code might be PIC (position independent code) or
non-PIC.
transaction A user-defined action that a client program (usually running on a workstation) requests from a
server.
Transaction
Management
Facility (TMF)
A set of HP software products for NonStop systems that assures database integrity by preventing
incomplete updates to a database. It can continuously save the changes that are made to a
database (in real time) and back out these changes when necessary. It can also take online
"snapshot" backups of the database and restore the database from these backups.
Transmission
Control
Protocol/Internet
Protocol (TCP/IP)
One of the most widely available nonvendor-specific protocols , designed to support large,
heterogeneous networks of systems.
trigger A trigger defines a set of actions that are executed automatically whenever a delete, insert, or
update operation occurs on a specified base table.
U-Z
Unicode A character-coding scheme designed to be an extension of ASCII. By using 16 bits for each
character (rather than ASCII's 7), Unicode can represent almost every character of every language
and many symbols (such as "&") in an internationally standard way, eliminating the complexity
of incompatible extended character sets and code pages. Unicode's first 128 codes correspond
to those of standard ASCII.
uniform resource
locator (URL)
A draft standard for specifying an object on a network (such as a file, a newsgroup, or, with
JDBC, a database). URLs are used extensively on the World Wide Web. HTML documents use
them to specify the targets of hyperlinks.
URL See uniform resource locator (URL).
virtual machine
(VM)
A self-contained operating environment that behaves as if it is a separate computer. See also
Java virtual machine and Java Hotspot virtual machine.
VM See virtual machine (VM).
World Wide Web
(WWW)
An Internet client - server hypertext distributed information retrieval system that originated from
the CERN High-Energy Physics laboratories in Geneva, Switzerland. On the WWW everything
(documents, menus, indexes) is represented to the user as a hypertext object in HTML format.
Hypertext links refer to other documents by their URLs. These can refer to local or remote resources
accessible by FTP, Gopher, Telnet, or news, as well as those available by means of the HTTP
protocol used to transfer hypertext documents. The client program (known as a browser ) runs
on the user's computer and provides two basic navigation operations: to follow a link or to send
a query to a server.
wrapper A shell script that sets up the proper execution environment and then executes the binary file that
corresponds to the shell's name.
WWW See World Wide Web (WWW).
