service processor (SP)
service processor (SP). A physical component of the processor multifunction (PMF)
customer-replaceable unit (CRU) or I/O multifunction (IOMF) CRU that controls
environmental and maintenance functions (including system load functions) in the
enclosure. SPs operate in pairs to provide fault tolerance. The two SPs in group 01
are designated the master service processors (MSPs). Other pairs of SPs within a
system are called expansion service processors (ESPs). See also expansion service
processor (ESP) and master service processor (MSP).
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your HP NonStop™ S-series server. OSM and
TSM allow you to use the help of a service provider by configuring client software to
support remote notification and remote access.
service side. The side of a system enclosure that contains, behind an optional door,
processor multifunction (PMF) customer-replaceable units (CRUs) or I/O multifunction
(IOMF) CRUs, ServerNet expansion boards (SEBs), modular SEBs (MSEBs), and
ServerNet adapters; it is opposite the appearance side. Cables are accessed from the
service side. System enclosures are typically arranged so that the service side is the
least visible side.
session. In the Open System Services (OSS) environment, a set of process groups
associated for job control purposes. A session can have a controlling terminal.
session leader. In the Open System Services (OSS) environment, the process that created
a session.
session lifetime. In the Open System Services (OSS) environment, the period that begins
when a session is created and ends when the lifetime of the last remaining process
group of the session ends.
setup configuration. A simple stand-alone network used to configure the OSM or TSM
environment. The setup configuration consists of the server, the primary system
console, an Ethernet hub, and two local area network (LAN) cables. One cable
connects the primary system console to the hub, and another cable connects the hub
to a processor multifunction (PMF) customer-replaceable unit (CRU) in group 01 of the
server. When OSM or TSM configuration is complete, the setup configuration can
serve as the working network configuration. Variations of the setup configuration can
be constructed using additional cables and hubs to increase fault tolerance.
set-user-ID program. In the Open System Services (OSS) environment, a program file that
has the S_ISUID bit set in its file mode.
shared memory. An interprocess communication mechanism that allows two or more
processes to share a given region of memory.
Shared Millicode Library. An intrinsic library containing privileged or TNS-derived millicode
routines used by many native-compiled programs and by emulated TNS programs.
This library includes efficient string-move operations, TNS floating point emulation, and
