save file A file created through the Inspect or Debug product. A save file contains enough information
about a running process at a given time to restart the process at the same point in its execution.
A save file contains an image of the process, data for the process, and the status of the process
at the time the save file was created.
A save file can be created through an Inspect SAVE command at any time. A save file called a
saveabend file can be created by the DMON debug monitor when a process’s SAVEABEND
attribute is set and the process terminates abnormally.
saveabend file A file containing dump information needed by the system debugging tool on a NonStop system.
In UNIX systems, such files are usually called core files or core dump files. A saveabend file is a
special case of a save file.
See also save file.
SCF See Subsystem Control Facility.
small OSS file A regular file that is smaller than approximately 2 gigabytes. Contrast with large OSS file.
special file A file associated with an I/O device. Often called a device file. Special files are read and written
the same as ordinary files, but requests to read or write result in activation of the associated
device. Due to convention and consistency, these files should always reside in the /dev directory.
See also file.
storage pool The set of disk volumes that contain files for a specific fileset or that can be used to contain files
for a specific fileset. The storage pool includes the creation pool.
storage-pool file A file containing a list of disk volumes to be used when creating new files in a fileset. As these
volumes are filled, more volumes can be added to the storage-pool file.
Subsystem Control
Facility
Standard online configuration and management tool for subsystems on a NonStop system.
super ID On HP 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.
superblock The part of the OSS environment that contains all the information about the current state of the
OSS file system. The superblock contains such items as the free list and the size of inodes.
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 A single copy of the HP NonStop operating system and the collection of hardware groups in
which it runs.
target directory
location (TDL)
The absolute pathname within the target OSS environment where the OSS files for configuration
are placed. One TDL can contain files for a single product or multiple products. TDL names are
contained in the A7CINFO file for each product and are transmitted to the target system in the
activation package instructions.
target subvolume
(TSV)
The subvolume name of a disk location on the target system where the software files for
configuration are placed. One TSV can contain files for a single product or multiple products.
TSV names are contained in the A0CINFO file for each product and are transmitted to the target
system in the activation package instructions.
TDL See target directory location (TDL).
terminal A type of character special file that conforms to the interface description in Clause 7 of ISO/IEC
IS 9945-1: 1990.
thread-aware
function
A function that blocks only the calling thread, instead of the entire process, if it must wait for I/O
to complete. Also called a thread-blocking function.
See also process-blocking function.
thread-blocking
function
See thread-aware function.
TSV See target subvolume (TSV).
