subsystem manager
process of the target subsystem. SCP also processes a few commands itself. It
provides security features, version compatibility, support for tracing, and support for
applications implemented as process pairs.
subsystem manager. A process that performs configuration and management functions for
a subsystem.
Subsystem Programmatic Interface (SPI). A set of procedures and associated definition
files and a standard message protocol used to define common message-based
interfaces for communication between management applications and subsystems. It
includes procedures to build and decode specially formatted messages; definition files
in Transaction Application Language (TAL), COBOL85, and HP Tandem Advanced
Command Language (TACL) for inclusion in programs, macros, and routines using the
interface procedures; and definition files in Data Definition Language (DDL) for
programmers writing their own subsystems.
subvolume. A group of related files stored on a disk; all the files have the same volume and
subvolume name, but each file has a unique file identifier.
summary report. A brief informational listing of status or configuration information provided
by the Subsystem Control Facility (SCF) STATUS or INFO command. Contrast with
detailed report.
superblock. The part of the Open System Services (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.
super group. The group of user IDs that have 255 as the group number. This group has
special privileges; many HP utilities have commands or functions that can be executed
only by a member of the super group.
super-group user. A user who can read, write, execute, and purge most files on the
system. Super-group users have user IDs that have 255 as the group number.
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 Open System Services (OSS) environment, the scalar view of
the super ID, which is 65535, is most commonly used.
super time factors (STFs). An enhancement to the Expand product that allows the
extension of automatically calculated time factors to line speeds greater than 224
kilobits/second. These time factors are logarithmic-based and allow specification of a
much broader range of line performance.
superuser. See super ID.
