Online Support Center (OSC)
communications line might temporarily affect applications that use the communications
line. Contrast with offline change.
Online Support Center (OSC). The group of support specialists within the HP Global
Customer Support Center (GCSC) who respond to telephone calls regarding system
problems and diagnose malfunctioning systems using remote diagnostic links. See
also Global Customer Support Center (GCSC).
Open Systems Interconnection (OSI). A seven-layer network architecture model defined
by the International Organization for Standardization (ISO). The two lowest layers deal
with the physical connections and their protocols. The five upper layers deal with
network services, such as network file transfers and accessing remote databases.
Open Systems Interconnection Layer 2. The data-link control level of the Open Systems
Interconnection (OSI) model, composed of asynchronous or minimal line control
protocols, byte-oriented or character-oriented protocols, and bit-synchronous or
bit-oriented protocols. Data link protocols can be defined in terms of method of access
of data, link relationship of stations, error detection scheme, error recovery, message
formatting, logical half-duplex or full-duplex operation, code, and machine
transparency.
operating system image. See OSIMAGE.
operator message. A message, intended for an operator, that describes a significant event
on a NonStop system. An operator message is the displayed-text form of an Event
Management Service (EMS) event message. See also event message.
OSC. See Online Support Center (OSC).
OSCONFIG file. In G-series RVUs, a configuration file built by SYSGENR that contains only
Software Problem Isolation and Fix Facility (SPIFF) and Software Identification (SWID)
tool records. In D-series and earlier RVUs, the Configuration Utility Program (COUP)
uses the $SYSTEM.SYSnn.OSCONFIG file to store its configuration information.
OSI. See Open Systems Interconnection (OSI).
OSIMAGE. A file built by the SYSGENR program and Subsystem Control Facility (SCF) that
contains the complete image of the NonStop Kernel operating system that runs in each
processor in the system.
OSM. Stands for HP Open System Management (OSM) Interface.
Replaces TSM as the system management tool of choice for NonStop S-series
servers. Provides the same functionality as TSM while overcoming limitations of TSM.
OSM is required for support of new functionality in G06.21 and later.
outage. Time during which a NonStop system is not capable of doing useful work. Outages
can be planned or unplanned. From the end user’s perspective, an outage is any time
