PIN
PIN. See process identification number (PIN).
PM. See product module (PM).
process. A program that has been submitted to the operating system for execution, or a
program that is currently running in the computer.
process ID. A number that uniquely identifies a process. It consists of the processor (CPU)
number and the process identification number (PIN).
process identification number (PIN). A number that uniquely identifies a process running
in a processor. The same number can exist in other processors in the same system.
See also process ID.
PROCESS object type. In a subsystem, the object type for the subsystem manager
process itself or any generic process.
product module (PM). The part of the Subsystem Control Facility (SCF) subsystem that is
responsible for subsystem-specific command processing.
PUP. See Peripheral Utility Program (PUP).
reconfiguration. The act of changing the hardware or software configuration of a running
system. Examples include installing a new software RVU, adding hardware
peripherals, and restructuring a database. Reconfiguring a system might or might not
require a planned outage.
resource. A component of a computer system that works together with other components to
process transactions. Terminals, workstations, processors, memory, disk drives,
processes, files, and applications are examples of resources.
response. The information or confirmation supplied by a subsystem in reaction to a
command. A response is typically conveyed as one or more interprocess messages
from a subsystem to an application.
SCF. See Subsystem Control Facility (SCF).
SCP. See Subsystem Control Point (SCP).
sensitive command. A Subsystem Control Facility (SCF) command that can be issued only
by a user with super-group access, by the owner of the subsystem, or by a member of
the group of the owner of the subsystem. The owner of a subsystem is the user who
started that subsystem (or any user whose application ID is the same as the server
ID—the result of a PROGID option that requires super-group access). Contrast with
nonsensitive command.
ServerNet/FX adapter. A ServerNet adapter that logically extends the ServerNet X and Y
fabrics to other clusters in a Fiber Optic Extension (FOX) ring by using fiber-optic lines.
Two ServerNet/FX adapters are used, one for the X ring and one for the Y ring.
