Subsystem Control Facility (SCF)
processes that manages a cohesive set of Subsystem Control Facility (SCF) objects.
Each subsystem has a manager through which applications can request services by
issuing commands defined by that subsystem. See also subsystem manager.
Subsystem Control Facility (SCF). An interactive interface for configuring, controlling, and
collecting information from a subsystem and its objects. SCF enables you to configure
and reconfigure devices, processes, and some system variables while your HP
NonStop S-series server is online.
Subsystem Control Point (SCP). The message router for SCF. There can be several
instances of this process. Using the Subsystem Programmatic Interface (SPI),
applications send each command for a subsystem to an instance of the SCP process,
which in turn sends the command to the manager process of the target subsystem.
SCP also processes a few commands itself. It provides security features, version
compatibility, support for tracing, and support for applications implemented as process
pairs.
subsystem manager. A process that performs configuration and management functions for
a Subsystem Control Facility (SCF) subsystem.
summary report. A brief informational listing of status or configuration information provided
by the Subsystem Control Facility (SCF) STATUS or INFO command. Contrast with
detailed report.
super group. The group of user IDs that have 255 as the group number. This group has
special privileges; many HP utilities have commands or functions that can be executed
only by a member of the super group.
super-group user. A user who can read, write, execute, and purge most files on the
system. Super-group users have user IDs that have 255 as the group number.
SWAN concentrator. See ServerNet wide area network (SWAN) concentrator.
SWID. A software identification tool whose records are contained in the
$SYSTEM.SYSnn.OSCONFIG file.
SYSGENR. The system generation program that generates a customized version of the HP
NonStop Kernel operating system.
system configuration database. The database file on the $SYSTEM.ZSYSCONF
subvolume that contains configuration information for all system objects that can be
configured by the Subsystem Control Facility (SCF). Configuration information for all
system objects that can be configured by SYSGENR is contained on the
$SYSTEM.SYSnn subvolume. See also configuration file.
system-managed process. Another name for a generic process. See generic process.
TACL. See HP Advanced Command Language (TACL).
