This view lists information about all database incarnations registered in the recovery catalog. Oracle creates a new incarnation whenever you open a database with the RESETLOGS option. Records about the current and immediately previous incarnation are also contained in the V$DATABASE view.

DBINC_KEY |
NUMBER |
The primary key for the incarnation. |
NAME |
VARCHAR2(8) |
The DB_NAME for the database at the time of the RESETLOGS. The value is UNKNOWN if you have done at least one RESETLOGS before registering the target database with RMAN, because RMAN does not know the DB_NAME before the RESETLOGS. |
