You can manage the TELNET subsystem interactively or programmatically. For the
TELNET subsystem, the Subsystem Control Facility (SCF) and VIEWPOINT provide
interactive subsystem management, while the control-and-inquiry interface and the
Event Management Service (EMS) interface provide programmatic subsystem
management.
The division of management tasks between operator control and programmatic control
depends upon the subsystem configuration 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.
Programmatic subsystem management can mean efficient use of resources as follows:
If routine management tasks are performed programmatically instead of
interactively, the operator can spend more time on tasks that require more
judgment and creativity.
Where appropriate, a management application can standardize responses to errors
or other information obtained from the subsystem. This standardization allows
you to establish procedures without having to train several operators on the
procedures.
A single management application can communicate with several subsystems.
You have more latitude in responding to errors returned by the subsystem. A
management application can be designed to take remedial action to selected
reported errors instead of requiring operator intervention once the errors are
reported.
You can customize a management application to respond to the specific needs of
your computer system or network.
