predefined value
predefined value. A commonly used value—for example, a value for a token or a field in a
token—that is given a name in a set of definition files.
print queue. In a NetWare network, a directory on the network on which print jobs are
stored. A printer is assigned to a print queue.
print server. In a NetWare local area network (LAN)
, a server that sends print jobs from a
print queue
to a network printer.
printing distributor. A Subsystem Control Facility (SCF)
distributor process that obtains
formatted text for select event messages and distributes it to a printer, to another display
device, or to a file.
process. A running entity that is managed by the operating system, as opposed to a program,
which is a collection of code and data. When a program is taken from a file on a disk
and run in a processor, the running entity is called a process.
programmatic command. In the Subsystem Control Facility (SCF)
, a command issued by a
program rather than interactively by a human operator. Contrast interactive command.
protocol. A formal description of message formats and the rules two or more machines must
follow to exchange those messages. Protocols can describe low-level details of machine-
to-machine interfaces (for example, the order in which the bits from a byte are sent
across a wire) or high-level exchanges between application programs (for example, the
way in which two programs transfer a file across the Internet). Most protocols include
both intuitive descriptions of the expected interactions and more formal specifications
using finite state-machine models.
PSERVER. A NetWare printer utility used to load a print server
on the file server after
services have been defined with PCONSOLE.
PTrace. A Compaq program used to display trace files created through the use of the
Subsystem Control Facility (SCF)
TRACE command.
QIO. See Queued Input/Output (QIO)
.
Queued Input/Output (QIO). A Compaq product that provides buffers and control blocks
for protocol processes, including the ServerNet LAN systems access (SLSA) subsystem
and the NonStop™ IPX/SPX subsystem running on the same processor.
Remote Server Call (RSC). A Compaq extension to NonStop™ Transaction Services/MP
(NonStop™ TS/MP) that allows workstation clients to access Pathway servers and other
Guardian processes on a NonStop™ Himalaya S-series server. RSC lets you implement
powerful client-server applications—the workstation is the client; the NonStop™
Himalaya S-series server with its NonStop™ TS/MP and Pathway/TS online transaction
processing (OLTP) software is the server—by taking advantage of the power of the
workstation with its extensive capabilities and easy-to-use graphical user interfaces
(GUIs).
