RC_DATAFILE

This view lists information about all datafiles registered in the recovery catalog. It corresponds to the V$DATAFILE view. A datafile is shown as dropped if its tablespace was dropped.

Column Datatype Description
DB_KEY NUMBER The primary key for this database in the recovery catalog. 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 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.
TABLESPACE_NAME VARCHAR2(30) The tablespace name. The name may exist multiple times in the same incarnation if the tablespace is dropped and re-created.
FILE# NUMBER The absolute file number of the datafile. The same datafile number may exist multiple times in the same incarnation if the datafile is dropped and re-created.
CREATION_CHANGE# NUMBER The SCN at datafile creation.
CREATION_TIME DATE The time of datafile creation.
DROP_CHANGE# NUMBER 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.
BYTES NUMBER The size of the datafile in bytes.
BLOCKS NUMBER The size of the datafile in blocks.
BLOCK_SIZE NUMBER The size of the data blocks in bytes.
NAME VARCHAR2(1024) The datafile filename.
STOP_CHANGE# NUMBER For offline or read-only datafiles, the SCN value such that no changes in the redo stream at an equal or greater SCN apply to this file.
STOP_TIME DATE For offline normal or read-only datafiles, the time beyond which there are no changes in the redo stream that apply to this datafile.
READ_ONLY NUMBER 1 if the file is read-only; otherwise 0.
RFILE# NUMBER The relative file number of this datafile within its tablespace.
INCLUDED_IN_DATABASE_BACKUP VARCHAR2(3) Indicates whether this tablespace is included in whole database backups: YES or NO. The NO value occurs only if CONFIGURE EXCLUDE was run on the tablespace that owns this datafile.
AUX_NAME VARCHAR2(1024) Indicates the auxiliary name for the datafile as set by CONFIGURE AUXNAME.
