HP-UX System Administrator's Guide: Overview

of a printer model script. Once created, the printer interface script can then be customized to tailor
it to your needs.
printer model
scripts
Scripts usually supplied as part of HP-UX or by a printer vendor used as templates (models)
from which printer interface scripts are created at the time printers are configured into the Line
Printer Spooling System.
PRM groups A collection of users and applications that are joined together and assigned certain amounts of
CPU, memory, and disk bandwidth resources.
processor A physical piece of silicon (a “chip”) containing one or more cores.
processor set
A group of cores, defined by the psrset command (or indirectly higher level products such as
the Workload Manager - WLM), for use as an independent scheduling domain. The default
processor set consists of all the cores on the system (server or partition).
pseudo swap System memory used for swap space that allows users to execute processes in memory without
allocating physical swap. Pseudo-swap is controlled by the operating-system parameter
swapmem_on which by default is set to 1, enabling pseudo-swap.
pseudodevice A virtual device, emulated by the operating system, not corresponding to a physical device. In
HP-UX 11i version 3, examples of pseudodevices include:
/dev/null
Receives and ignores all input.
/dev/random
A source of random numbers.
There are many others.
RAID An acronym meaning Redundant Array of Independent Disks. RAID defines various ways (known
as RAID Levels) to group mass storage devices to achieve data redundancy or read/write
performance.
reject
One of four commands that control the flow of print requests through the Line Printer Spooling
System (spooler). reject instructs the spooler to prevent print requests from being added to a
print queue.
See also accept, enable, disable.
remote printer A printer connected directly to a remote instance of HP-UX (“system”). Print requests to a remote
printer must first travel over a network to the remote system. The Line Printer Spooling System
on the remote system subsequently handles the printing of the requests as though they were local
requests.
Note: The remote instance of HP-UX could be on the same physical server, in an alternate nPartition
for example.
remote
spooling
Spooling to printers that are defined in the Line Printer Spooling System (spooler) of a different
server or HP-UX instance. The local spooler accepts print requests and submits them to the remote
spooler on your behalf. The remote spooler then handles the printing of the requests.
Role-Based
Access
Control
Role-Based Access Control. An HP-UX mechanism to provide fine-grained access to system
resources, commands, and system calls. Users are assigned to roles and users are granted access
privileges according to roles.
root directory The top most directory in the HP-UX directory tree. The root directory is represented by the path
/”.
root file
system
The file system containing the root directory. It is the first file system mounted during the boot
sequence and contains the mount points to which other file systems are mounted.
See also mount points.
root volume
group
The LVM volume group that contains the root file system and primary swap volume.
See also root file system and primary swap.
