Chapter 6 Oracle Tablespace and File Internals Scripts

In Oracle9i or earlier releases, to rename a tablespace from OLD_TBS to NEW_TBS, you have to go through the following steps:

  1. Create a new tablespace NEW_TBS.
     

  2. Copy all objects from OLD_TBS to NEW_TBS.
     

  3. Drop tablespace OLD_TBS.

In Oracle10g, you can accomplish the same thing in one step:

  • Rename tablespace OLD_TBS to NEW_TBS.

ALTER TABLESPACE RENAME old_tbs to new_tbs;

Example 2: Transport a tablespace between two databases

In the example below (see figure 6.5), you cannot transport a tablespace TBS01 from database A to database B in the previous release of Oracle server because database B also has a tablespace called TBS01.  In Oracle10g, you can simply rename TBS01 to TBS02 in database B before transporting tablespace TBS01.

Mike Ault’s Oracle Internals Monitoring & Tuning Scripts
 

Written by the world's top DBA and author of over 20 Oracle books, Mike Ault shares his secrets for Oracle DBA management scripts.  This handy reference is indispensable for all Oracle professionals who must quickly automate and manage their Oracle databases with scripts.

This stellar book comes complete with an online code depot full of over 200 pre-tested Oracle DBA scripts, and covers all areas of Oracle database administration including data files, tablespace, table and index management scripts.  Based on more than 20 years full-time experience, Mike Ault brings his expertise to the public with this fantastic book.  Your time savings from a single script is worth the price of this great book.

Mike Ault is one of the leading names in Oracle technology.  The author of 20 books and hundreds of articles in national publications, Mike was the first popular Oracle author with his landmark book "Oracle7 Administration and Management".  Mike also wrote several of the "Exam Cram" books, and enjoys a reputation as a leading author and Oracle consultant.

Mike started working with computers in 1979 right out of a stint in the Nuclear Navy. He began working with Oracle in 1990 and has since become a World Renowned Oracle expert (in the words of his publisher anyway!) Mike has written 14 Oracle related books, dozens of articles, and has presented at conferences in Europe and the USA. Mike has two wonderful daughters and is kept out of trouble by his wife of 29 years, Susan.
