NUMBER |
The primary key for this database in the recovery catalog. Use this column to form a join with almost any other catalog view. |

The primary key for the incarnation of the target database. Use this column to form a join with RC_DATABASE_INCARNATION. |
DB_NAME |
VARCHAR2(8) |
The DB_NAME of the database incarnation to which this record belongs. |
TS# |
NUMBER |
The number of the tablespace to which the datafile belongs. The TS# may exist multiple times in the same incarnation if the tablespace is dropped and re-created. |

CREATION_CHANGE# |
NUMBER |
The SCN at datafile creation. |
CREATION_TIME |
DATE |
The time of datafile creation. |
DROP_CHANGE# |

The SCN recorded when the datafile was dropped. If a new datafile with the same file number is discovered then the DROP_CHANGE# is set to CREATION_CHANGE# for the datafile; otherwise the value is set to RC_CHECKPOINT.CKP_SCN. |
DROP_TIME |
DATE |
The time when the datafile was dropped. If a new datafile with the same file number is discovered then the DROP_TIME is set to CREATION_TIME for the datafile; otherwise the value is set to RC_CHECKPOINT.CKP_TIME. |
