Primary System Processes

On the primary system:
• The monitor process coordinates most RDFCOM commands involving the main RDF
processes (for example, start and stop).
• Each extractor process reads an audit trail (the MAT or a particular auxiliary audit trail),
filters out audit records not relevant to the backup database, transforms the audit record
into an image record, and then transmits the image records to an associated receiver process
on the backup system. Some control information for synchronizing the extractor and receiver
process pair is included each time the extractor process transmits the audit records.
