Surendra is correct.

The datafiles are NOT opened in mount state. The Controlfile gets read in MOUNT state. Oracle doesn't even check the existence of the datafiles until it tries to OPEN.

With the DB in MOUNT state, use the "alter databae rename datafile 'oldname' to 'mewname' >This AFTER you (as wad advised) cp the file to the new location.

You do NOT have to recreate the controlfile.

To change maxdatafiles, maxlogmembers, etc you would need to recreate.....

You cannot move the system tablespace, you have to re-create the =3D control=3D20
files to change the system data file's path.

=3D

To move the temp tablespace:

create tablespace temp1 datafile 'new_mount_point_data_file_name' size =
=3D

<n>;

then ...

alter user <username> temporary tablespace temp1; --> for the users =3D that=3D20
have temporary tablespace temp!

then ...

drop tablespace temp including contents and datafiles;

=3D

To move the undo tablespace:

create undo tablespace undotbs2 datafile =3D 'new_mount_point_data_file_name'=3D20
size <n>;

alter system set undo_tablespace=3D3Dundotbs2;

drop tablespace undotbs1 including contents and datafiles;

=3D
