NonStop S-series servers
NonStop S-series servers. The set of HP NonStop servers having product numbers
beginning with the letter S. These servers implement the ServerNet architecture and
run the HP NonStop Kernel operating system.
NonStop TCP/IP. The HP implementation of TCP/IP for HP NonStop servers. TCP/IP is a
set of layered communications protocols for connecting workstations and larger
systems.
NonStop TCP/IP subsystem. A subsystem that allows the use of HP NonStop TCP/IP to
access a HP NonStop S-series host from Macintosh computers, personal computers,
and UNIX workstations. Applications running on a NonStop S-series system or in an
Expand network can transparently exchange data with NonStop TCP/IP devices.
null object type. A placeholder object type for the Subsystem Control Facility (SCF)
NAMES and VERSION commands, which do not require explicit specification of a
particular object type.
OBEY file. See command file.
object. One or more of the devices, lines, processes, and files in a subsystem; any entity
subject to independent reference or control by one or more subsystems. In the
Subsystem Control Facility (SCF), each object has an object type and object name.
object name. A unique name for an SCF object within a subsystem.
object-name template. A name that stands for more than one Subsystem Control Facility
(SCF) object. Such a name includes one or more wild-card characters, such as *
(asterisk) and ? (question mark). See also wild-card character.
object type. The category of Subsystem Control Facility (SCF) objects to which a specific
SCF object belongs; for example, a specific disk has the object type DISK and a
specific terminal may have the object type SU. Each subsystem has a set of object
types for the objects it manages.
offline. (1) Used to describe tasks that are performed outside of the control of an application
or computer system. (2) Used to describe tasks that require system resources to be
shut down. Contrast with online.
offline change. Any change that requires system resources to be shut down. Offline
changes are usually performed during a planned outage. Contrast with online change.
online. Used to describe tasks that can be performed while the HP NonStop Kernel
operating system and system utilities are operational. Contrast with offline.
online change. Any change that can be performed while an application or its system
resources are operational. In some situations, online changes might temporarily affect
subsystem and application availability. For example, altering the characteristics of a
communications line might temporarily affect applications that use the communications
line. Contrast with offline change.
