persistence
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 count. The number of times the $ZPM persistence manager process will
restart a generic process that has been terminated abnormally. A generic process with
an AUTORESTART value of 10 (the maximum) is said to have a persistence count of
10. See also persistence.
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
release version updates (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.
physical interface (PIF). The hardware components that connect a system node to a
network.
physical link interfaces. Communications standards defined by standards organizations.
These physical link interfaces are supported for the ServerNet wide area network
(SWAN) concentrator: RS-232, RS-442, RS-449, V.35, and X.21.
Physical view. One of several views of a server available in the view pane of the
Management window of the OSM Service Connection, TSM Service Application, and
OSM and TSM Low-Level Link. A Physical view of a server is a view of all the
enclosures and is intended to represent the actual floor plan at the site. A Physical
view of an enclosure is a visual representation of the physical placement of supported
resources inside the enclosure. See also Connection view
.
PIB. See power interface board (PIB)
.
PIC. (1) See plug-in card (PIC). (2) See position-independent code (PIC).
PID. In the Open System Services (OSS) environment, a synonym for process ID. OSS
process ID is the preferred term in HP NonStop™ system publications.
In the Guardian environment, PID is sometimes used to mean either:
•
A Guardian process identifier such as the process ID
•
The cpu, pin value that is unique to a process within an Expand node (See
process identification number (PIN).)
PIF. See physical interface (PIF).
