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 join with almost any other catalog view.
DBINC_KEY NUMBER The primary key for the incarnation of the target database. Use this column to 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.
TEMPORARY VARCHAR2(3) YES if tablespace is a locally managed temporary tablespace. Otherwise, NO.
ENCRYPT_IN_BACKUP VARCHAR2(3) Possible values are:
  • ON. Encryption is turned ON at tablespace level

  • OFF. Encryption is turned OFF at tablespace level

  • NULL. Encryption is neither explicitly turned on or off at tablespace level (default or when CLEARED)
