Figure 4 RDF Subsystem Processes
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.
