Pathway/TS
Pathway/TS. A Compaq product that provides tools for developing and interpreting screen
programs to support OLTP applications in the Guardian operating environment.
PEEK. A utility program that reports statistical information concerning processor activity for
system storage pools, paging activity, send instructions, and interrupt conditions.
Peruse. A spooler utility that allows users to control and monitor print jobs.
performance management. Activities that manage the performance of the production
system and network environment to ensure that the systems meet the business needs
defined by operations service-level agreements. One of the operations disciplines in the
operations management model. See
operations management model (OM model).
peripheral device. Any device used by processors to communicate with users or to acquire
or store data. Peripheral devices include terminals, printers, workstations, disk drives,
and tape drives.
physical interface (PIF). The hardware components that connect a system node to a
network.
physical outage class. An outage class that includes physical faults or failure in the
hardware. Any type of hardware-component failure belongs in this category. See outage

planned outage. Time during which the system is not capable of doing useful work because
of a planned interruption. A planned outage can be time when the system is brought
down to allow for servicing, upgrades, backup, or general maintenance. Contrast with
unplanned outage.

system. The primary processor is the processor that has direct control over the
controller. See
backup processor .
printing distributor. An EMS distributor process that sends operator messages to printers,
devices, processes, or files.
problem management. Activities that provide support for resolving problems in a
production environment. One of the operations disciplines in the operations
management model. See
operations management model (OM model).
