OSI/FTAM Subsystem Architecture

The Tandem FTAM software allows you to access, transfer, and manage files on an OSI

network. Tandem FTAM services allow you to create, delete, read, and modify files in

addition to reading and changing file attributes. These services are accessed through the

FTAM application program interface (API). For more information about this interface

and the functions it provides, see the Tandem OSI/FTAM Programming Reference

Manual.

OSI/APLMGR and OSI/FTAM Subsystems

Tandem FTAM is managed through two subsystems: the Tandem OSI/Application

Manager (APLMGR) subsystem and the FTAM subsystem. Figure 1-1 on page 1-4

presents an overview of these two subsystems.

As shown in the figure, the APLMGR subsystem consists of the APLMGR process and

the management information base (MIB). The FTAM subsystem consists of initiator and

responder processes. The figure also illustrates the interfaces to Tandem FTAM and the

subsystems with which it must communicate. The sections that follow describe the

entities illustrated in this figure and their functions.

In general terms, the APLMGR subsystem allows you to configure and manage Tandem

FTAM processes, and the FTAM subsystem allows you to monitor initiator and

responder processes and manage the subdevices of those processes. SCF sends

interactive commands to the Subsystem Control Point (SCP), which routes them to an

APLMGR, initiator, or responder process based on the form of the process object name.

Note. By default, FTAM processes run at a high PIN. If you want the APLMGR to run at a low

PIN, you must specify this in the RUN command. For initiator and responder processes, you

can specify the attribute HIGHPIN OFF in the ADD PROCESS or ALTER PROCESS

command.
