V$Block_Change_Tracking 19C. Block change tracking provides how to spot the blocks required for backup without scanning the entire datafiles. If block change tracking is enabled, then rman uses the change tracking file to identify changed blocks for incremental backups, thus. Rman tracks changed blocks as redo is generated. Then rman need only read blocks that are really required for this incremental backup i.e rman uses this file to spot the changed blocks that require to be backed up. If block change tracking is enabled on a primary or standby. Oracle 10g introduced the block change tracking (bct) feature which is used to speed up rman incremental backup. V$block_change_tracking displays the status of block change tracking for the database. Sql> alter database enable block change tracking using file ‘/u01/clone/datafile/blockfile.log’; Block change tracking tracks data file blocks affected by each database update. How to enable block change tracking: With oracle’s block change tracking (bct) functionality, you no longer need to scan all blocks from a previous incremental. Enable block change tracking and check the status. Sql> select name from v$database;
