Guardian services
Guardian services. An application program interface (API) to the HP NonStop™ operating
system, plus the tools and utilities associated with that API. This term is synonymous
with Guardian environment. See also Guardian.
Guardian user ID. See HP NonStop™ operating system user ID.
header. An object that, when specified for inclusion in a program’s source code, causes the
program to behave as if the statement including the header were actually a specific set
of other programming statements. A header contains coded information that provides
details (such as data item length) about the data that the header precedes.
In an Open System Services (OSS) program, a header is the name of a file known to
the run-time library used by a process. In a Guardian environment C language
program, a header is the file identifier for a file known to the run-time library used by a
process.
HP NonStop™ Open System Services (OSS). The product name for the OSS
environment. See also Open System Services (OSS).
HP NonStop™ Kernel operating system. The former name of the operating system for HP
NonStop systems. See HP NonStop™ operating system user ID.
HP NonStop™ operating system user ID. A user ID within an HP NonStop system. The
Guardian environment normally uses the structured view of this user ID, which consists
of either the group-number, user-number pair of values or the
group-name.user-name pair of values. For example, the structured view of the
super ID is (255, 255). The Open System Services (OSS) environment normally uses
the scalar view of this user ID, also known as the UID, which is the value
(group-number * 256) + user-number. For example, the scalar view of the super ID
is (255 * 256) + 255 = 65535.
HP NonStop™ operating system. The operating system for HP NonStop systems.
HP NonStop™ System EPIC Model A processor (NSE-A processor). The model
designation for the TNS/E processor used in the HP NonStop NS10000 server.
HP NonStop™ Technical Library (NTL). The application for accessing, searching, and
viewing technical publications and support information for the HP NonStop server. NTL
replaces Total Information Manager (TIM).
HP Tandem Advanced Command Language (TACL). The user interface to the HP
NonStop™ operating system. The TACL product is both a command interpreter and a
command language. Users can write TACL programs that perform complex tasks or
provide a consistent user interface across independently programmed applications.
HP Transaction Application Language (TAL). A systems programming language with
many features specific to stack-oriented TNS systems.
