RC_TABLESPACE

This view lists all tablespaces registered in the recovery catalog, all dropped tablespaces, and tablespaces that belong to old incarnations. It corresponds to the V$TABLESPACE view. The current value is shown for tablespace attributes.

Column	Datatype	Description
`DB_KEY`	`NUMBER`	The primary key for the target database. Use this column to form a join with almost any other catalog view.
`DBINC_KEY`	`NUMBER`	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 tablespace ID in the target database. The `TS#` may exist multiple times in the same incarnation if the tablespace is dropped and re-created.
`NAME`	`VARCHAR2(30)`	The tablespace name. The name may exist multiple times in the same incarnation if the tablespace is dropped and re-created.
`CREATION_CHANGE#`	`NUMBER`	The creation SCN (from the first datafile).
`CREATION_TIME`	`DATE`	The creation time of the tablespace. `NULL` for offline tablespaces after creating the control file.
`DROP_CHANGE#`	`NUMBER`	The SCN recorded when the tablespace was dropped. If a new tablespace with the same `TS#` is discovered then the `DROP_CHANGE#` is set to `CREATION_CHANGE#` for the tablespace; otherwise, the value is set to `RC_CHECKPOINT`.`CKP_SCN`.
`DROP_TIME`	`DATE`	The date when the tablespace was dropped.
`INCLUDED_IN_DATABASE_BACKUP`	`VARCHAR2(3)`	Indicates whether this tablespace is included in whole database backups: `YES` or `NO`. The `YES` value occurs only if `CONFIGURE` `EXCLUDE` was run on the tablespace that owns this datafile.
`BIGFILE`	`VARCHAR2(3)`	Indicates whether this tablespace is a tablespace created with the `BIGFILE` option.
