MasterLan II-T2 Adaptor Card
MasterLan II-T2 Adaptor Card. A dual-ported network adaptor that helps to provide a fault-
tolerant connection between a PC and a network hub.
master machine. The master machine for a NonStop Tuxedo application as designated in
the configuration file. The master machine contains the NonStop Tuxedo administrative
programs, the master configuration file, and the DBBL process. All administration of
the NonStop Tuxedo application is done from the master machine.
Measure. An HP software utility that allows system performance to be monitored for
purposes of balancing workloads, managing growth, and optimizing data storage and
communications.
mirrored disk. A pair of identical disk drives that are used together as a single logical
volume. One drive is considered the primary, and the other is called the backup or
mirror. Each byte of data written to the primary drive is also written to the backup drive.
If the primary drive fails, the backup drive can continue operations.
mom process. A process that is notified when certain other processes are deleted. When a
process is part of a process pair, the mom of the process is the other member of the
pair. When a process is unnamed, its mom is usually the process that created it.
monolithic program. An online transaction-processing design approach in which a single
program performs all of the data input, data manipulation, and data output tasks of a
transaction-processing application. Additionally, the single program controls all
terminals connected to the system and manages communications with other systems.
Multilan. A hardware and software product that allows users to connect their local area
networks (LANs) through a reliable NETBIOS communication protocol to HP NonStop
systems. See also Network Basic Input/Output System (NETBIOS).
multithreaded process. A process with potentially more than one sequential flow of control
or thread. Each thread can be separately dispatched. Multithreaded processes save
overhead by dispatching separate threads instead of having the operating system
create additional processes. An example of a multithreaded process is a terminal
control process (TCP). Contrast with single-threaded process
. See also thread and
terminal control process (TCP)
.
NCL. See Network Control Language (NCL).
NetBatch. Automated job management system that schedules and dispatches batch jobs.
NetBatch-Plus. A Pathway application that provides a screen-driven interface to the
NetBatch job management system. You can use the application, which has its own
database, to control NetBatch systems running on different nodes.
NETBIOS. See Network Basic Input/Output System (NETBIOS).
Network Basic Input/Output System (NETBIOS). A de facto industry standard LAN
interface intended to be independent of LAN hardware or software, freeing application
