service side
service side. The rear side of a HP NonStop™ S-series system enclosure. It contains
processor multifunction (PMF) customer-replaceable units (CRUs) or I/O multifunction
(IOMF) CRUs, ServerNet expansion boards (SEBs) or modular SEBs (MSEBs), and
ServerNet adapters. The service side is opposite the appearance side. All cables are
accessed from the service side. Most service actions are performed from the service
side. Service side doors are supplied with later NonStop S-series servers but are
optional on earlier servers. Service-side doors are cosmetic and are not required for
system cooling.
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 for an HP NonStop™ S-series server 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.
shadow. The processor used to check the results of the master processor on a processor
board.
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
various privileged-only operations. These routines are mode independent. They
comply with native calling conventions but can be directly invoked from any mode
without changing execution modes.
shared run-time library (SRL). A collection of procedures whose code and data can be
loaded and executed only at a specific assigned virtual memory address (the same
address in all processes). SRLs use direct addressing and do not have run-time
resolution of links to and from the main program and other independent libraries.
