# Temporary Datafiles

Locally managed temporary tablespaces have temporary datafiles (tempfiles), which are similar to ordinary datafiles except that:

    Tempfiles are always set to NOLOGGING mode.

    You cannot make a tempfile read-only.

    You cannot rename a tempfile.

    You cannot create a tempfile with the ALTER DATABASE command.

    Media recovery does not recognize tempfiles.

        BACKUP CONTROLFILE does not generate any information for tempfiles.

        CREATE CONTROLFILE cannot specify any information about tempfiles.

    Tempfile information is shown in the dictionary view DBA_TEMP_FILES and the dynamic performance view V$TEMPFILE, but not in DBA_DATA_FILES or V$DATAFILE.
