hot site. See operational-ready site.
ICC. See Integrated Command and Control (ICC).
Integrated Command and Control (ICC). A Microsoft Windows workstation component of
DSM/NOW. ICC provides a point-and-click object browser for Tandem host subsystem
objects and maps related commands from various subsystem command interfaces to
clickable buttons. See also Distributed Systems Management/NonStop Operations for
Windows (DSM/NOW).
International Tandem Users’ Group (ITUG). An independent organization of Tandem
users that encourages communication and information exchange, establishes a forum for
special interest groups, and provides feedback to Tandem regarding users’ needs.
ITUG. See International Tandem Users’ Group (ITUG).
Kernel-Managed Swap Facility (KMSF). A facility for managing virtual memory. Through
KMSF, the NonStop Kernel opens one or more swap files for each processor and
manages the files for all the processes needing them. KMSF receives requests for swap
space from the NonStop Kernel, and returns swap-space reservations to the Kernel.
Processes swap to the kernel-managed swap files as needed. As a process’s need for
swap space grows, KMSF increases the amount of swap space reserved for the process.
When the process no longer needs the space, it is returned to KMSF. See also
NSKCOM.
KMSF. See Kernel-Managed Swap Facility (KMSF).
Launcher. A Microsoft Windows workstation component of DSM/NOW. The Launcher
provides operations personnel with console environments specifically tailored to help
them accomplish their operational duties. The Launcher can start useful applications
automatically when an operator logs on or the operator can start applications on demand
by selecting them from organized lists of utilities. See also Distributed Systems
Management/NonStop Operations for Windows (DSM/NOW).
least privilege. A security concept that allows users access to only the system resources they
need.
licensed program. A program that has the privileges of the operating system. When a
licensed program runs, privileged operations in it can bypass ordinary security
interfaces.
macro. A sequence of TACL commands and built-in functions that can contain dummy
arguments, thus providing a means for simple argument substitution. When the macro
name is given to TACL, TACL substitutes the command sequence for the macro name
and replaces any dummy arguments with parameter values supplied to TACL. Macros
are used to automate operations tasks.
management application. A program or set of programs that issues commands to
subsystems, retrieves event messages, or does both things, to assist in managing a
system or a network of systems.
