RDF Processes

To accomplish its four major tasks, RDF runs different processes on the primary

system and the backup system. These processes (the monitor and extractor on the

primary system and the receiver, updaters, and purger on the backup system) divide

these tasks as summarized in the following pages. The relationship of these processes

to one another is illustrated in Figure 1-4. More details about their operation appear

under RDF Operations.
