Glossary
NLCHECK. A state in labeled-tape processing. If NLCHECK is on, you must give
permission for an unlabeled tape operation to open a tape drive by accepting the mount
request through MEDIACOM. If NLCHECK is off, the unlabeled tape open can finish
without permission. Regardless of the setting, you can perform labeled-tape operations.
NO UNLOAD. A state in labeled-tape processing. When you set NOUNLOAD, tapes remain
online after labeling operations. When you clear NOUNLOAD, the system unloads
tapes after it completes labeling operations.
node. A physical computer system that is part of an Expand network. It can be a stand-alone
system or be part of a network of systems.
nonsensitive command. A command that can be issued by any user or program that is
allowed access to the subsystem—that is, a command on which the subsystem imposes
no further security restrictions. For Subsystem Control Facility (SCF) subsystems,
nonsensitive commands are those that cannot change the state or configuration of
objects; most of them are information commands. Contrast with "sensitive command."
NonStop™ TM/MP. See
NonStop™ Transaction Manager/MP (NonStop™ TM/MP). A database-protection
subsystem incorporated into the operating system. NonStop™ TM/MP maintains the
consistency and integrity of a distributed database that is updated by concurrent
transactions.
NonStop™ Virtual Hometerm Subsystem (VHS). A subsystem that acts as a virtual home
terminal for applications by emulating a 6530 terminal. NonStop™ VHS receives
messages normally sent to the home terminal, such as displays and application prompts,
and uses these messages to generate event messages for EMS, which can in turn be used
to inform operations staff of problems.
NSKCOM. The command interface to the Kernel-Managed Swap Facility (KMSF).
NSKCOM is the primary tool for monitoring, configuring, and managing
kernel-managed swap files. See
NSX. See Tandem Network Statistics Extended (NSX).
OBEY file. See command file.
object. (1) One or more of the devices, lines, processes, and files in a NonStop™ Kernel
subsystem; any entity subject to independent reference or control by one or more
subsystems. (2) In Subsystem Control Facility (SCF), a resource controlled by an SCF
subsystem. SCF objects include processes, disks, disk files, and data communications
lines. Each object has an object type and an object name.
object type. The category of Subsystem Control Facility (SCF) objects to which a specific
SCF object belongs; for example, a specific disk has the object type DISK and a specific
terminal may have the object type SU. An SCF subsystem has a set of object types for
the objects it manages.
NonStop™ Transaction Manager/MP (NonStop™ TM/MP).
