System Startup, Configuration, and Shutdown Reference Manual (32650-90892)

263
spooling An activity that permits the concurrent use of output devices and batch job
input. (SPOOL is an acronym for simultaneous peripheral operations online.) If multiple
users send output to a 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.
