Another great new feature in tablespace management is rename tablespace.

Tablespace Rename Overview

In Oracle 10g, you can simply rename a tablespace TBS01 to TBS02 by issuing the following command:

     ALTER TABLESPACE tbs01 RENAME TO tbs02;

However, you must follow the rules when renaming a tablespace:

• You must set compatibility level to at least 10.0.1.
• You cannot rename the SYSTEM or SYSAUX tablespaces.
• You cannot rename an offline tablespace.
• You cannot rename a tablespace that contains offline datafiles.
• Renaming a tablespace does not changes its tablespace identifier.
• Renaming a tablespace does not change the name of its datafiles.

Tablespace Rename Benefits

Tablespace rename provides the following benefits:

• It simplifies the process of tablespace migration within a database.
• It simplifies the process of transporting a tablespace between two databases.

Example 1: Rename a tablespace within a database. In Oracle9i or earlier releases, you must take the following steps to rename a tablespace from OLD_TBS to NEW_TBS:

1. Create a new tablespace NEW_TBS.
2. Copy all objects from OLD_TBS to NEW_TBS.
3. Drop tablespace OLD_TBS.

In Oracle 10g, you can accomplish the same thing in one step:

• Rename tablespace OLD_TBS to NEW_TBS.

     ALTER TABLESPACE RENAME old_tbs to new_tbs;
