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. | 
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 temp file. The same temp file number may exist in the same incarnation of the temp file is dropped and re-created. | 
CREATION_CHANGE# | 
NUMBER | 
The SCN when the temp file is created. | 
CREATION_TIME | 
DATE | 
The time when the temp file is created. | 
DROP_CHANGE# | 
NUMBER | 
The SCN recorded when the temp file was dropped. If a new temp file with the same FILE# is discovered, then the DROP_CHANGE# is set to CREATION_CHANGE# for the temp file; otherwise, the value is set to RC_CHECKPOINT.CKP_SCN. | 
DROP_TIME | 
DATE | 
The time when the temp file was dropped. If a new temp file with the same FILE# is discovered, then the DROP_TIME is set to CREATION_TIME for the temp file; otherwise the value is RC_CHECKPOINT.CKP_TIME. | 
BYTES | 
NUMBER | 
The size of the temp file in bytes. | 
BLOCKS | 
NUMBER | 
Size of the file in blocks. | 
BLOCK_SIZE | 
NUMBER | 
The block size of the temp file in bytes. | 
NAME | 
VARCHAR2(1024) | 
The temp file name. | 
RFILE# | 
NUMBER | 
The relative file number of this temp file within the tablespace. | 
AUTOEXTEND | 
VARCHAR2(3) | 
ON if the temp file is autoextensible. Otherwise OFF. | 
MAXSIZE | 
NUMBER | 
Maximum file size in blocks to which the file can be extended. Valid only when AUTOEXTEND is ON. Always 0 when AUTOEXTEND is OFF. | 
NEXTSIZE | 
NUMBER | 
Amount of incremental size for file extensible in blocks. Valid only when AUTOEXTEND is ON. Always 0 when AUTOEXTEND is OFF. | 
BIGFILE | 
VARCHAR2(3) | 
YES if the tablespace is a bigfile tablespace; otherwise, NO. | 
SITE_KEY | 
NUMBER | 
Primary key of the Data Guard database associated with this file. Each database in a Data Guard environment has a unique SITE_KEY value. You can use SITE_KEY in a join with the RC_SITE view to obtain the DB_UNIQUE_NAME of the database. | 
TABLESPACE_CREATION_CHANGE# | 
NUMBER | 
SCN at which this tablespace was created. | 
TABLESPACE_CREATION_TIME | 
DATE | 
Timestamp at which this tablespace was created. | 
TABLESPACE_DROP_CHANGE# | 
NUMBER | 
SCN at which this tablespace was dropped. | 
TABLESPACE_DROP_TIME | 
DATE | 
Timestamp at which the tablespace was dropped. | 
DB_UNIQUE_NAME | 
VARCHAR2(512) | 
The DB_UNIQUE_NAME of the database incarnation to which this record belongs. All databases in a Data Guard environment share the same DBID but different DB_UNIQUE_NAME values. The value in this column is null when the database name is not known for a specific file. For example, rows for databases managed by versions of RMAN before Oracle Database 11g are null. |
