  • CURRENT - SQL Apply is currently applying changes contained in the foreign archived log

  • NO - SQL Apply has not started applying any changes contained in the foreign archived log

  • FETCHING - SQL Apply encountered a corruption while reading redo records from this foreign archived log, and is currently using the automatic gap resolution to refetch a new copy of the log from the primary database

  • CORRUPT - SQL Apply encountered a corruption while reading redo records from this foreign archived log, and refetching a new copy of the archived log did not resolve the problem. SQL Apply will not refetch a new copy of this archived log automatically, and will require user intervention to manually register a new copy of the foreign archived log.
