NonStop System Glossary

TNS/R native object file
An object file created by a TNS/R native compiler that contains MIPS RISC instructions and other
information needed to construct the code spaces and the initial data for a TNS/R native process.
TNS/R native process
A process initiated by executing a TNS/R native object file. Contrast with TNS process and TNS/E
native process.
TNS/R native shared run-time library (TNS/R native SRL)
A shared run-time library (SRL) available to TNS/R native processes in both the Guardian and
Open System Services (OSS) environments. TNS/R native SRLs can be either public or private. A
TNS/R native process can have multiple public SRLs but only one private SRL.
TNS/R native signal
A signal model available to TNS/R native processes in both the Guardian and Open System
Services (OSS) environments. TNS/R native signals are used for error exception handling.
TNS/R native user library
A user library available to TNS/R native processes in both the Guardian and Open System Services
(OSS) environments. A TNS/R native user library is implemented as a special private TNS/R native
shared run-time library (TNS/R native SRL).
TNSVU
A tool used to browse through TNS object files that have been accelerated by the TNS Object
Code Accelerator (OCA). TNSVU displays Itanium code in addition to TNS code. Contrast with
Accelerated Program Examiner (APE).
token
A character sequence processed as a unit by a command process.
Token-Ring ServerNet adapter (TRSA)
A ServerNet adapter that provides a single line from a NonStop server to a token-ring network,
allowing the server to act as a station on the ring. The 3862 TRSA can be configured to support
network speeds of 4 megabits/second (Mbps) or 16 Mbps, and the media can be either shielded
twisted pair (STP) or unshielded twisted pair (UTP).
topology
The physical layout of components that define a local area network (LAN), wide area network
(WAN), or ServerNet fabric. See also star topology and tetrahedral topology.
topology branch
A processor enclosure and the I/O enclosures attached to it.
total harmonic distortion (THD)
The ratio, expressed in percent, of the root mean square (rms) value for all harmonics present in
the output of a power source to the total rms voltage at the output, for a pure sine-wave output.
The lower the THD, the better the power source.
