AM3270 Management Programming Manual

SECTION 2
MANAGEMENT PROGRAMMING FOR AM3270
You can manage the AM3270 subsystem interactively or programmati-
cally. For 6100 CSS environments, the Subsystem Control Facility
(SCF), the Communications Management Interface (CMI), and
VIEWPOINT provide interactive subsystem management, while the
control-and-inquiry interface and the Event Management Service
(EMS) interface provide programmatic subsystem management. Note
that although the Configuration Utility Program (COUP) is an
interactive interface, it will not be compared with the control-
and-inquiry interface. COUP has limited application to the
AM3270 subsystem; you can only add or delete a process or line
using this facility.
The division of management tasks between operator control and
programmatic control depends upon the subsystem configuration,
the subsystem environment, and your needs as a subsystem user.
To determine the most effective division of management tasks,
you must be familiar with the functions available to you in both
the interactive and programmatic interfaces. The interactive
functions available depend on the interactive interface you
are using, SCF or CMI. Tables later in this section show
the commands available programmatically and those available
interactively.
