What is Block Change Tracking? Block Change Tracking is an Oracle Database feature used with RMAN incremental backups. It tracks the physical locations of changed blocks in the database and stores this information in a separate file called the Block Change Tracking file. Oracle documentation states that this tracking information is maintained in a separate file and is used for tasks such as improving incremental backup performance. Without BCT, RMAN may need to scan the datafiles to determine which blocks have changed since the previous backup. With BCT enabled, RMAN can directly read the change tracking file and identify changed blocks more efficiently. ----- Login to SQL sqlplus / as sysdba            Set lin 400 SELECT status, filename, bytes FROM   v$block_change_tracking; CHECK OMF SHOW PARAMETER db_create_file_dest;  ENABLE BCT (BLOCK CHAIN TRACKING) Common method: ALTER DATABASE ENABLE BLOCK CHANGE TRACKING;  Add to a file path:...
