Move segments from one Tablespace to another:Move Tables of user
PROD_USER like this:
Tables + indexes of tables
EMP,PRODUCTS,CUSTOMERS into tablespace
TBS1.
All the other tables + indexes of this user into tablespace
TBS2.
The Script:set serveroutput on
--***********************************************
-- (Run the script as DBA user)
-- Parameters:
---------------
-- user_name : owner to which to move segments
-- TBS1 : Tablespace-A
-- Tables_TBS1 : list of tables to move to tablespace-A
-- TBS2 : tablespace to move all tables NOT in the list
-- put_Output : if 'true' - create output of operations (dbms_output)
-- put_Execute : if 'true' - execute the move operations
