SRL
full SUT contains the current RVU of the HP NonStop operating system and all product
software that has been ordered with it. A partial SUT contains a subset of products for
the current RVU.
SRL. See shared run-time library (SRL).
startup sequence. A convention for sending and receiving certain messages while starting
a new process. By convention, the new process receives an Open message, followed
by a Startup message, an Assign message for each ASSIGN in effect, a Param
message if there are any PARAMs in effect, and then a Close message.
state information. In active backup programming, information about a program’s execution
environment that is periodically sent from the primary process to the backup process.
In the event of a primary process failure, the backup process uses the state information
to take over execution at or near the logical point of failure.
stop mode. An attribute that a process can use to protect itself from being stopped by other
processes.
structured file. A disk file in which records are saved according to a predefined structure.
See relative file. key-sequenced file, and entry-sequenced file for examples. Contrast
with unstructured file.
subvolume. A group of files stored on disk. These files all have the same subvolume name
but each has a different file ID. For example, $DATA.INFO identifies the subvolume
named INFO on the volume $DATA. An example of a file name is
$DATA.INFO.RESULTS.
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.
superuser. See super ID.
SUT. See site update tape (SUT).
SYSnn subvolume. A subvolume on the $SYSTEM volume where the new version of the
HP NonStop™ operating system image is located. Also located on the SYSnn
subvolume is system-dependent and release version update (RVU)-dependent
software. nn is an octal number in the range %00 through %77.
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 HP NonStop™ operating system image and operated as one computer.
