Oracle Rename and delete tablespaces

Oracle Rename and delete tablespaces

You can modify the name of a table space as needed. Modifying the table space name does not affect the data in the table space. However, the system tablespace and sysaux names cannot be modified.
The syntax for renaming a tablespace is as follows:
Alter tablespace tablespace_name rename to new_tablespace_name;
Note:
If the tablespace status is offline, The tablespace cannot be renamed.
Delete a tablespace
To delete a tablespace, use the drop tablespace statement. The syntax is as follows:
Drop tablespace tablespace_name [including contents [and datafiles]
Syntax description:
Including contents
Deletes all database objects in the tablespace while deleting the tablespace. This option is required if the tablespace contains database objects.
And datafiles
Delete the data files corresponding to the tablespace while deleting the tablespace. If this option is not applicable, the delete tablespace only deletes information about the tablespace from the data dictionary and control file, and does not delete the data files corresponding to the tablespace in the operating system.
