AM3270 Management Programming Manual

INTRODUCTION
Subsystem Architecture
You can manage the AM3270 subsystem through both interactive and
programmatic interfaces. The interactive interfaces for managing
the AM3270 subsystem are the following:
• The Subsystem Control Facility (SCF), which can be used to
monitor, configure, and control the AM3270 subsystem. SCF
provides an operator interface to the Subsystem Control Point
(SCP) which provides an interface to the AM3270 subsystem.
SCF can be used for the AM3270 subsystem only in 6100 CSS
environments.
• The Communications Management Interface (CMI), which can be
used to configure and control the line and subdevices, as well
as to obtain information from the AM3270 subsystem about the
line and subdevices. This interface can be used only in the
6100 Communications Subsystem (6100 CSS) environment and is
being replaced with SCF.
• The Configuration Utility Program (COUP), which can be used to
dynamically add or delete processes.
• VIEPOINT, which can be used to monitor event messages that
display at the VIEWPOINT console.
The programmatic interfaces for managing the AM3270 subsystem are
the following:
• The control-and-inquiry interface, which provides control and
inquiry capability to an application program. An application
program can send a command to a subsystem to control the
subsystem or to obtain information.
• The Event Management Service (EMS) interface which provides
event-management capability to an application program. This
interface allows an application program to retrieve event
messages previously sent to EMS by the subsystem.
The programmatic management interfaces use SPI message formats
and conventions and can only be used in a 6100 CSS environment.
When selecting the interfaces that would best serve your manage-
ment needs, determine the features and capabilities of each and
the environment in which they will be used.
