Open System Services Installation Guide (H06.16+, J06.05+)

OSSMON See Open System Services (OSS) Monitor.
pathname In the OSS file system and Network File System (NFS), the string of characters that uniquely
identifies a file within its file system. A pathname can be either relative or absolute. See also
ISO/IEC IS 9945-1:1990 (ANSI/IEEE Std. 1003.1-1990 or POSIX.1), Clause 2.2.2.57.
regular file In the OSS file system, a file that is a randomly accessible sequence of bytes. A regular file
contains binary or text data and has no structure imposed by the system. Contrast with .
remote operator The person who performs routine system operations from a geographical distance, usually when
no local operator is present.
root See root fileset and root directory.
See also Super ID.
root directory In the Open System Services (OSS) file system and Network File System (NFS), a directory
associated with a process that the system uses for pathname resolution when a pathname begins
with a slash (/) character.
root fileset For the OSS file system, the fileset with the device identifier of 0 (zero), normally containing the
root directory. HP recommends that this fileset be named "root".
root user See super ID.
ServerNet cluster A network of servers (nodes) connected together using the ServerNet protocol for interprocessor
communication across a cluster and within its nodes. A ServerNet cluster offers linear system
expansion beyond the 8-processor or 16-processor limits of a single server, achieving comparable
speeds for internal and external ServerNet communication.
See also cluster, HP NonStop™ ServerNet Cluster (ServerNet Cluster). .
ServerNet node A system in a storage pool.
See also node.
shell In the OSS environment, a program that interprets sequences of text input as commands. The
OSS shell can operate on an input stream or it can interactively prompt and read commands
from a terminal.
special file A file in the OSS file system that is not a regular file. Special files include directories, FIFOs, and
character special files such as terminal device files. Contrast with regular file.
storage pool A set of physical disk volumes administered as a set of logical disk volumes. A logical disk volume
can span multiple physical disk volumes. When a logical disk volume becomes full, more physical
disk volumes can be added.
storage-pool file A file containing a list of disk volumes to be used by an OSS fileset. As these volumes are filled,
more volumes can be added to the storage-pool file.
super ID On NonStop systems, a privileged user who can read, write, execute, and purge all files on the
system. The super ID is usually a member of a system-supervisor group.
The super ID has the set of special permissions called appropriate privileges. In the Guardian
environment, the structured view of the super ID, which is (255, 255), is most commonly used;
in the OSS environment, the scalar view of the super ID, which is 65535, is most commonly used.
superuser See super ID.
symbolic link A type of special file that acts as a name pointer to another file. A symbolic link contains a
pathname and can be used to point to a file in another fileset. Symbolic links are not included
in ISO/IEC IS 9945-1: 1990. Compare to hard link.
system All the processors, controllers, firmware, peripheral devices, software, and related components
that are directly connected together to form an entity that is managed by one NonStop Kernel
operating system image and operated as one computer.
See also node.
system
administrator
The person responsible for the installation and configuration of a software subsystem on a NonStop
node.
system manager See manager.
system operator See local operator and remote operator
terminal A type of character special file that conforms to the interface description in Clause 7 of ISO/IEC
IS 9945-1: 1990.
