RC_TEMPFILE

This view lists information about all tempfiles registered in the recovery catalog. It corresponds to the V$TEMPFILE view. A tempfile is shown as dropped if its tablespace is dropped.

Column Data Type 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.
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 tempfile. The same tempfile number may exist in the same incarnation of the tempfile is dropped and re-created.
CREATION_CHANGE# NUMBER The SCN when the tempfile is created.
CREATION_TIME DATE The time when the tempfile is created.
DROP_CHANGE# NUMBER The SCN recorded when the tempfile was dropped. If a new tempfile with the same FILE# is discovered, then the DROP_CHANGE# is set to CREATION_CHANGE# for the tempfile; otherwise, the value is set to RC_CHECKPOINT.CKP_SCN.
DROP_TIME DATE The time when the tempfile was dropped. If a new tempfile with the same FILE# is discovered, then the DROP_TIME is set to CREATION_TIME for the tempfile; otherwise the value is RC_CHECKPOINT.CKP_TIME.
BYTES NUMBER The size of the tempfile in bytes.
BLOCKS NUMBER Size of the file in blocks.
BLOCK_SIZE NUMBER The block size of the tempfile in bytes.
NAME VARCHAR2(1024) The tempfile name.
RFILE# NUMBER The relative file number of this tempfile within the tablespace.
AUTOEXTEND VARCHAR2(3) ON if the tempfile 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.
