OSCONFIG file
OSCONFIG file. In G-series RVUs, a configuration file built during system configuration 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.
OSIMAGE. A file built by the SYSGENR program and Subsystem Control Facility (SCF) that
contains the complete image of the HP NonStop Kernel operating system that runs in
each processor in the system.
OSM. See HP NonStop Open System Management (OSM) Interface.
OSM Event Viewer. OSM replacement for the TSM Event Viewer.
OSM Low-Level Link. OSM replacement for the TSM Low-Level Link.
OSM Notification Director. OSM replacement for the TSM Notification Director.
OSM Service Connection. OSM replacement for the TSM Service Application.
output destination. The resource to which Subsystem Control Facility (SCF) sends its
responses to commands. SCF can direct output to a disk file, an application process, a
terminal, or a printer. The initial output destination is determined by the form of the
RUN command used to initiate SCF. The output destination can be changed
dynamically during an SCF session.
PARAM. A TACL command and a Subsystem Control Facility (SCF) command you can use
to create a parameter and give it a value. The TACL process stores the values of
parameters assigned by the PARAM command and sends the values to applications
that request parameter values.
Peripheral Utility Program (PUP). A utility used in D-series and earlier RVUs to manage
disks and other peripheral devices. In G-series RVUs, PUP functions are performed by
the Subsystem Control Facility (SCF).
persistence. For the Subsystem Control Facility (SCF), the capability of a generic process
to restart automatically if it was stopped abnormally. You configure this capability by
specifying a nonzero AUTORESTART value in an ADD command.
persistence manager process. The $ZPM process that is started and managed by the
$ZCNF configuration utility process and that starts generic processes in G-series
RVUs and manages their persistence.
persistent configuration. A configuration that remains the same from one system load to
another.
persistent process. A process that must always be either waiting, ready, or executing.
Persistent processes are usually controlled by a monitor process that checks on the
status of persistent processes and restarts them, if necessary.
