Tandem FTAM Components
FTAM Application Program Interface (API)
The FTAM API allows you to write applications that use the initiator services of Tandem
FTAM. The FTAM API provides a set of procedures that implement ISO FTAM initiator
functions. Programmers can incorporate these procedures into applications developed in
either the Tandem Transaction Application Language (TAL) or the C programming
language.
These procedures allow you to exert a great deal of control over an application and its
use of FTAM protocol. To use these procedures, however, you should have a knowledge
of the FTAM protocol because the application must issue procedure calls in the correct
order and be sensitive to the context in which each call is made.
For specific information regarding the FTAM API and its procedure calls, see the
Tandem OSI/FTAM Programming Reference Manual and the Tandem OSI/FTAM
Programming Guide.
Management Interfaces
The Tandem Distributed Systems Management (DSM) interface provides a management
interface to configure, monitor, and control Tandem FTAM on your local node and on
remote nodes. You can use three DSM tools with Tandem FTAM:
•
Subsystem Control Facility (SCF)
•
PTrace (print trace) utility
•
Operator messages, through the Event Management Service (EMS)
These tools are described further in Section 2, FTAM Management Environment
.
Tandem FTAM Components
Figure 1-2 on page 1-5 shows the components of Tandem FTAM: the Application
Manager (APLMGR) process and management information base (MIB), FTAM initiator
processes, and FTAM responder processes. Note that the APLMGR process and its
MIB, which are part of Tandem FTAM, are distinct from the OSI manager process and
its MIB, which are part of the OSI/AS subsystem. The relationship of the OSI manager
process and the OSI manager MIB to Tandem FTAM is discussed in Section 3, Planning,
Installing, and Configuring Tandem FTAM, and in the following subsections:
•
Application Manager (APLMGR) Subsystem on page 1-6
•
FTAM Subsystem on page 1-6
For systems management, the Tandem FTAM software consists of two subsystems: the
APLMGR subsystem and the FTAM subsystem. The APLMGR subsystem consists of
the APLMGR process and its MIB; the APLMGR manages the configuration and
operation of Tandem initiator and responder processes. The FTAM subsystem consists of
initiator and responder processes and manages subdevices associated with those
processes.
