Logic Diagram and Directory Structure

Figure F-2 is a logical diagram of the SAF. It illustrates how a single service access controller may spawn a number of port monitors on a per-system basis. This means that several monitors may be running concurrently, providing for the simultaneous operation of several different protocols.

Figure F-1 SAF Logical Framework

"/etc/saf/_sysconfig" is the corresponding directory structure diagram. Following the diagram is a description of the files and directories.

Port monitor pmtag's administrative file. Contains information about the services for which pmtag is responsible.

/etc/saf/pmtag/svctag

The file in which the per-service configuration script for service svctag (available through port monitor pmtag) is placed.

/etc/saf/pmtag/_pid

The file in which a port monitor writes its process id in the current directory and places an advisory lock on the file.

/etc/saf/pmtag/_pmpipe

The file in which the port monitor receives messages from the sac and ../_sacpipe and sends return messages to the sac.
