Can any one please let me know why I can't view, even I have the Dba Priviliges, RECOVERY_CATALOG_OWNER Priviliges and Imp_Full_Database

and all of thses Roles have Create any View.

Here is the Query.
create or replace view tbv
as select TABLESPACE_NAME,
sum( BYTES) allocated_space
from dba_data_files
group by TABLESPACE_NAME;

Gives that Object Does not exits
But if I Issue this select statement, that works fine.

Thanks in Advance.
