All,=20 I've got a large (4G.) datafile let's call him BIG.dbf on one of my = database servers that I'm not sure what's living in it. =20 I did run the following sql statement: SQL> select TABLESPACE_NAME, BYTES, BLOCKS from DBA_DATAFILES 2 where FILE_NAME =3D '/oracle/dbs/BIG.dbf'; no rows selected Does this mean that this is an empty file? I'm a little puzzled. Thanks,=20 Richard Jaehne -- //www.freelists.org/webpage/oracle-l
