FDBA or Flash Data Archiver Processesback,”When a transaction that modifies a tracked table commits, FBDA stores the pre-image of the rows in the archive. FDBA maintains metadata on the current rows and tracks how much data has been archived.FBDA is also responsible for automatically managing the flashback data archive for space, organization (partitioning tablespaces)
and retention. FBDA also keeps track of how far the archiving of tracked transactions has progressed.”
