spool queue
Glossary
246246
nonshareable device, such as a tape drive or line
printer, their output is directed to spool files on disk.
The output is printed on a priority basis as the
printer becomes available and the users can proceed
with other processing activities without waiting for
the printer. Multiple batch jobs can also be
submitted concurrently. The jobs are spooled to disk
and executed according to the priority level specified
by its submitter with the JOB command.
spool queue Disk space where spool files are kept.
START An initial system loader (ISL) utility and its
options that is used to start the system from disk
and to build the system data structures. This utility
is used to recover from a hang or failure or to reboot
the system after scheduled downtime. The START
RECOVERY option is equivalent to the MPE V/E
WARMSTART procedure, and the START
NORECOVERY option is equivalent to the MPE V/E
COOLSTART procedure.
$STDIN A system-defined file name that refers to the
standard input device used to initiate a session or
job; usually a terminal keyboard, card reader, or
tape drive.
$STDLIST A system-defined file name indicating the
standard job or session listing file corresponding to
the particular input device being used. The listing
device is usually a printer for batch jobs and a
terminal for sessions.
storage device A device (such as a disk pack, a disk
cartridge, a flexible disk, magnetic tape, or cartridge
tape) onto which data can be stored and
subsequently retrieved.
STORE 1) The process of saving HP 3000 files to tape
or serial disk. Storing is executed by using the STORE
command. 2) A machine instruction that tells the
CPU to take information from a register and put it
in memory.
stream To run batch jobs or data from a session or a
job by using the MPE STREAM command. Once a job
is streamed, it will execute as a separate process
without requiring any further user input or
supervision.
subsystem A software program that performs a
specific function, such as compiling programs,
copying files, or editing text. Subsystems are
executed by entering a single command at the colon
prompt. At that point a different prompt is
displayed, and a set of commands specific to the
subsystem become available to the user. The user
must explicitly exit the subsystem, usually by
entering E or EXIT.
SYS account A special account on the HP 3000
system, included with the system when it is first
installed. It contains all MPE files (stored in the
segmented library), supported subsystems, utility
programs, and compilers.
system A group of one or more CPUs that
communicate through buses without the use of data
communications software.
system abort An orderly system failure. MPE trys
to clean up by closing files and flushing buffers when
possible.
system configuration The process of tailoring the
operating system to accommodate the current
physical layout and workload of a particular
installation. The configuration is typically modified
when new terminals, another line printer, or a disk
drive are added. The system also can be reconfigured
to assign new class names to existing devices,
change the size of system tables or virtual memory,
modify system logging, or alter any other
configuration parameter.
system console 1) A workstation given a unique
status by the operating system. It is used by the
operator to execute specific commands for the
purpose of managing sessions, jobs, and system
resources. It is associated with all boot or system
loader error messages, system error messages, and
certain system status messages. 2) The terminal,
usually logical device 20, that the system operator
uses to monitor system activity, respond to resource
requests, and send messages to user’s terminals. The
console (and its associated privileges and
responsibilities) may be transferred to another
logical device with the CONSOLE command.
system control panel A panel on the computer,
containing control switches and status indicator
lights.
system-defined files The files defined by MPE and
made available to all users to indicate standard
input or output devices, special temporary files, and
files opened for output that do not perform an actual
write operation.
