+col file_name for a70
+select file_id, file_name, status, online_status from dba_data_files where tablespace_name = 'TS_THALER_DATA' order by 1;
+</code>
+or
+=== Check the status of the tempfiles ===
+<code>
+set lines 1000 pages 100
+col file_name for a70
+select v.file#, t.file_name, v.status from dba_temp_files t, v$tempfile v where t.file_id = v.file# order by 1;
+</code>
+=== Set the relevant datafile offline ===
+<code>
+alter database datafile 125 offline;
+alter database datafile 126 offline;
+alter database datafile 127 offline;
+</code>
+=== Rename the files on the filesystem using o/s commands ===
+This has to be done before the alter otherwise the alter will fail (it checks that the destination file exists)
+<code>
+alter tablespace ts_thaler_data_offline;
+host mv '/cln/tst/ora_data1/clnt/data4/ts_thaler_data_113.dbf' '/cln/tst/ora_data1/clnt/data1/ts_thaler_data_113.dbf'

+</code>
+=== Run the relevant alter commands to inform the control files of the new locations ===
+<code>
+alter database move datafile '/cln/tst/ora_data1/clnt/data4/ts_thaler_data_113.dbf' to '/cln/tst/ora_data1/clnt/data1/ts_thaler_data_113.dbf'

+alter database move datafile '/cln/tst/ora_data1/clnt/data4/ts_thaler_data_115.dbf' to '/cln/tst/ora_data1/clnt/data1/ts_thaler_data_115.dbf'
+</code>
+=== Recover the datafiles ===
+This step is skipped when renaming tempfiles
+<code>
+recover datafile 125;
+recover datafile 126;
+recover datafile 127;
+</code>
+=== Set the relevant datafile online ===
+<code>
+alter database datafile 125 online;
+alter database datafile 126 online;
+alter database datafile 127 online;
+</code>
+=== Rename a datafile on 12c and higher ===
+If you're lucky enough to be on 12c or higher it's one command - no need to offline the datafile!
+<code>
+SQL> alter database move datafile '/oracle/ora_data2/prod/data4/ts_thaler_data_113.dbf' to '/oracle/ora_data2/prod/data3/ts_thaler_data_113.dbf';

+It is possible to login as the user by saving, changing and resetting his password (using identified by values) but using dbms_sys_sql is another option
 Create a PL/SQL procedure to drop a db link

+<code>
