owner
owner. (1) In the case of a disk file, the user or program that created the file, or a user or
program to whom the creator has given the file with the File Utility Program (FUP)
GIVE command. (2) In the case of a process, the user or program that created the
process or, if the PROGID option was specified in the FUP SECURE command for the
code file, the user or program that owns the code file. (3) In the case of a token or
other definition, the subsystem that provided the definition. (4) In the case of a
subsystem, the company or organization that provides the subsystem, or the
8-character string identifying that company.
packet. A block of information that contains fields for addressing, sequencing information,
possible priority indicators, and a portion of a message or an entire message. See also
ServerNet packet.
page. See memory page.
Parallel Library TCP/IP. An HP product that provides increased performance and scalability
over conventional Transmission Control Protocol/Internet Protocol (TCP/IP). Parallel
Library TCP/IP coexists with conventional TCP/IP on HP NonStop™ systems. See also
HP NonStop™ TCP/IP.
PARAM. An HP Tandem Advanced Command Language (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.
parent directory. A particular directory in the hierarchy of directories within a file system.
The parent directory for a directory contains an entry for that specific directory and is
identified in that directory as the directory immediately above it in the hierarchy. The
parent directory for a file contains an entry for that file.
parent process. The process that created a given process or (if the creating process has
stopped) a process that has inherited a given process. See also child process.
parent process ID. In the Open System Services (OSS) environment, an attribute of a child
process determined by the parent process. The parent process ID is the OSS process
ID of the current parent process.
parity. The use of an extra bit on memory chips that serves as a checksum so the operating
system can detect if single-bit memory errors are occurring.
passthrough terminator. See SCSI passthrough terminator.
path. The route between a processor and a subsystem. If a subsystem is configured for
fault tolerance, it has a primary path (from the primary processor) and a backup path
(from the backup processor).
pathname. In the Open System Services (OSS) file system and Network File System
(NFS), the string of characters that uniquely identifies a file within its file system. A
