Go Up to Available object actions by DBMS

The Placement dialog lets you place tables and indexes on different segments. From a performance standpoint it is not recommended to have a table and its supporting indexes on the same device or disk segment. It is also good to have more frequently accessed indexes and tables grouped together on higher speed devices, if possible.
