How SCF Works

Figure 1-3 illustrates the SCF management interface to Tandem FTAM.

This figure shows that commands are entered interactively to SCF, which consists of the

basic SCF product and the SCF product modules (PMs) for each subsystem. The product

modules provide the subsystem-specific SCF processes, and handle the subsystem-

specific commands and screen displays. All SCF modules forward commands to the

Subsystem Control Point (SCP).

SCP, in turn, forwards commands to the appropriate APLMGR, initiator, and responder

processes. These processes return responses to SCP, which returns them to SCF. If

necessary, SCF sends information (in the form of SCF displays or messages) to your

terminal.

The intermediate SCP process provides the interface between SCF and Tandem FTAM.

Commands that SCP sends to FTAM initiator and responder processes can be sent

directly to an individual process or can be sent indirectly through the APLMGR process

The dotted lines in Figure 1-3

indicate how commands are passed to processes

indirectly, through the APLMGR process. Commands pertaining to the APLMGR

subsystem are always sent directly to the APLMGR process.
