Hi Srinivas, The actual statement shouldn't be too hard to find in the Oracle documentation. I have a clue that it is one of the options of the 'ALTER TABLESPACE' statement, but you can find it yourself if you do some searching at the Oracle site (I 'd have a link for you if I were at work. ). For the rest, it seems a question of connecting to Oracle using your admin account and executing the statement (probably use Statement.execute() instead of Statement.executeQuery()). Good riding, Rudy.
