Oracle Error ORA-39309: Cannot alter tablespace between bigfile and smallfile.

Oracle Error Message

ORA-39309: Cannot alter tablespace between bigfile and smallfile.

Reason for the Error

DBMS_METADATA_DIFF was comparing two tablespaces, one bigfile, one smallfile. There is no SQL ALTER statement to change a tablespace from smallfile to bigfile or vice versa.

Solution

The difference cannot be eliminated with an SQL ALTER statement.
