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

• n: Where n is the applicable container ID for the rows containing data
