DEFINES paragraph
DEFINES paragraph. An optional paragraph in the CONFTEXT configuration file that
contains one or more identifiers, each with its associated text string. The DEFINES
paragraph, if used, precedes the ALLPROCESSORS paragraph.
DISKGEN. A SYSGENR option that invokes the DISKGEN program to copy directly to disk
those files necessary to generate a NonStop Kernel operating system. DISKGEN can
be used instead of a system image tape (SIT).
Distributed Systems Management/Software Configuration Manager (DSM/SCM). A
graphical user interface (GUI)-based program that installs new software and creates a
new NonStop Kernel operating system. DSM/SCM creates a new software revision and
activates the new software on the target system.
distribution subvolume (DSV). A subvolume containing program files for a particular
software product along with the software RVU document (softdoc) file for that product.
The format for a DSV name is Ynnnnrrr or Rnnnnrrr, where nnnn is the software
product number and rrr is the base version identifier (such as D20) or interim product
modification (IPM) identifier (such as AAB).
DSC. See Dynamic System Configuration (DSC).
DSM/SCM. See Distributed Systems Management/Software Configuration Manager
(DSM/SCM).
DSV. See distribution subvolume (DSV).
Dynamic System Configuration (DSC). A utility used in D-series and earlier RVUs to
make online changes to the configuration of devices and controllers. Its interactive
utility is called the Configuration Utility Program (COUP). In G-series RVUs, DSC
functions are performed by Subsystem Control Facility (SCF).
EMS. See Event Management Service (EMS).
Event Management Service (EMS). A Distributed Systems Management (DSM) product
that provides event collection, event logging, and event distribution facilities. EMS
provides different event descriptions for interactive and programmatic interfaces, lets
an operator or an application select specific event-message data, and allows for
flexible distribution of event messages within a system or network.
file name. A unique name for a file. In the Guardian environment on NonStop S-series
systems, disk file names include a disk volume name, a subvolume name, and a file
identifier. An example of a file name on a NonStop S-series system is
$DISK.SUBVOL.MYFILE. For files that are network accessible, the node name
precedes the volume name: \NODE.$DISK.SUBVOL.MYFILE.
firmware. Code in memory that is necessary for power-up initialization and communication
with a host or device.
