Taking a Tablespace Offline

Taking a Tablespace Offline
You may want to take a tablespace offline for any of the following reasons:
■ To make a portion of the database unavailable while still allowing access to the
remainder of the database
■ To make an application and its group of tables temporarily unavailable while

■ To perform an offline tablespace backup (even though a tablespace can be backed

■ To recover a tablespace after a hardware or software failure
■ To rename or relocate tablespace data files
