DSM/SCM
DSM/SCM. See Distributed Systems Management/Software Configuration Manager
(DSM/SCM).
DTE. See data terminal equipment (DTE).
dynamic information. Information that represents the set of resources that actually exist in
the current configuration of a NonStop S-series server. Dynamic information is
gathered from a server through the process of discovery. Contrast with static
information.
dynamic process configuration. Using Subsystem Control Facility (SCF) to configure a
generic process to always start in a designated primary processor.
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).
EMS collector. An Event Management Service (EMS) process to which subsystems report
events.
error number. For Subsystem Control Facility (SCF) and Subsystem Programmatic
Interface (SPI), a value that can be assigned to a return token, or to the last field of an
error token, to identify an error that occurred. SPI defines a small set of error numbers,
but most error numbers are defined by using SCF subsystems.
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.
event message. Text intended for a system operator that describes a change in some
condition in the system or network, whether minor or serious. The change of condition
is called an event. Events can be operational errors, notifications of limits exceeded,
requests for actions needed, and so on. See also operator message.
Event Viewer Server Manager. A persistent process that routes messages and data
between the TSM EMS Event Viewer Application on the TSM workstation and event
server and summary server processes on the NonStop S-series server. An event
server process retrieves events. A summary server is a persistent process that
maintains a summary of all the events in a specified log file.
exception handler. A section of program code to which control is transferred when an
exception occurs. The exception handler then determines what action should be taken.
