NonStop Kernel
NonStop Kernel. The HP operating system, which consists of the core and system
services. The operating system does not include any application program interfaces
(APIs).
NonStop TCP/IP. The HP implementation of Transmission Control Protocol/Internet
Protocol (TCP/IP) for the HP NonStop servers. See also Parallel Library TCP/IP and
NonStop TCP/IPv6.
NonStop TCP/IP process. An HP product that supports the Transmission Control
Protocol/Internet Protocol (TCP/IP) layers. TCP/IP processes are used together with
the communications line interface processor (CLIP) pNA+ to provide the transport layer
between wide area network (WAN) I/O processes and data link control (DLC) tasks,
between ConMgr and the Simple Network Management Protocol (SNMP) task,
between the WANBoot process and BOOTP tasks, and between a TSM process and a
DIAG task.
NonStop TCP/IP subsystem. A subsystem that allows the use of HP NonStop TCP/IP to
access an 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.
NonStop TCP/IPv6. An HP product that adds IP version 6 (IPv6) functionality to the Parallel
Library TCP/IP product. IPv6 is a TCP/IP protocol that extends the IP version 4 (IPv4)
Internet address of 32 bits to 128 bits. NonStop TCP/IPv6 can be run in three modes:
INET (supports only IPv4 communications and is a direct replacement for Parallel
Library TCP/IP), INET 6 (only IPv6), and DUAL (both IPv4 and IPv6 communications).
nowait input/output (I/O). In the Guardian file system, a mode of operation in which the
called procedure initiates an input/output (I/O) operation but does not wait for it to be
completed before returning control to the caller.
object. (1) One or more of the devices, lines, processes, and files in an HP subsystem; any
entity subject to independent reference or control by one or more subsystems;
(2) In the Subsystem Control Facility (SCF), a resource controlled by an SCF
subsystem. SCF objects include processes, disks, disk files, and data communications
lines. Each object has an object type and an object name.
Open Systems Interconnection (OSI). A data communications model developed by the
International Standards Organization (ISO) in 1977.
Originator/Recipient (O/R) name. A unique means of identifying an originator or a recipient
of messages to a message handling system (MHS). An O/R name can be either a
name or an address.
OSI. See Open Systems Interconnection (OSI).
