Oracle Tutorials - Keep Data Files When Tablespace Dropped
(Continued from previous topic...)
What Happens to Data Files If a Tablespace Is Dropped?
If a tablespace is dropped, what happens to its data files?
By default, data files will remain in OS file system, even if the tablespace
they are mapped is dropped. Of course, you delete the data files using OS commands,
if they are no longer needed.
Another way of deleting data files is to use the INCLUDING clause in the
DROP TABLESPACE statement. Here is a SQL sample script:
SQL> CREATE TABLESPACE my_space
2 DATAFILE '/temp/my_space.dbf' SIZE 10M;
SQL> DROP TABLESPACE my_space INCLUDING CONTENTS
2 AND DATAFILES;
With the INCLUDING CONTENTS AND DATAFILES clause, all contents and mapped data files
are also deleted.
