V$BLOCK_CHANGE_TRACKING displays the status of block change tracking for the database.

Column Datatype Description
STATUS VARCHAR2(10) Status of block change tracking in the database:
  • DISABLED - Block change tracking is disabled

  • TRANSITION - Block change tracking is in the process of transitioning between the enabled and disabled states. The TRANSITION state should usually never be observed, because it only exists while enabling or disabling block change tracking. This state might be observed if the instance crashed while enabling or disabling block change tracking, in which case it will be cleaned up automatically the next time that the database is opened.

  • ENABLED - Block change tracking is enabled

FILENAME VARCHAR2(513) Name of the block change tracking file for the database
BYTES NUMBER Size of the block change tracking file (in bytes)
