outage
outage. Time during which a computer system is not capable of doing useful work. Outages
can be planned or unplanned. From the end user’s perspective, an outage is any time
an application being used is not available. See also planned outage and unplanned
outage.
outage minutes. A metric for measuring outages that translates percentages into
minutes/year of downtime.
output destination. The resource to which Subsystem Control Facility (SCF) sends its
responses to commands. SCF can direct output to a disk file, an application process, a
terminal, or a printer. The initial output destination is determined by the form of the
RUN command used to initiate SCF. The output destination can be changed
dynamically during an SCF session.
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
eight-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™ S-series systems
and supports Ethernet 4 ServerNet adapters (E4SAs), Fast Ethernet ServerNet
adapters (FESAs), Gigabit Ethernet ServerNet adapters (GESAs), and ServerNet wide
area network (SWAN) concentrators. 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.
