Hi,

and also verfy that X$dual is access after this , this can checked with explain plan.
If x$dual is not acces then consider to drop dual table, and do followings:

conn sys as sysdba

desc x$dual

create or replace view v_dual as select dummy from sys.x$dual where inst_id = userenv('INSTANCE');

grant select on v_dual to public;
drop public synonym dual;

create public synonym dual for v_dual;

now try the "select 'Hello' from dual order by 1 desc;";

set autot traceonly exp;

SQL> select 'Hello' from dual order by 1 desc;

Execution Plan


          0
SELECT STATEMENT Optimizer=CHOOSE

          1                  0

  FIXED TABLE (FULL) OF 'X$DUAL' SQL> set autot off
SQL> /
'HELL

Hello

Can any body try the following in 9.2.0.4

SQL> select object_name,object_type,owner from dba_objects where object_name like '%DUAL%';
OBJECT_NAME



OBJECT_TYPE OWNER
------------------ ------------------------------
DUAL
TABLE SYS DUAL
SYNONYM PUBLIC Instead of using dual table, use memory structure x$dual;

connect sys as sysdba

desc x$dual

create view v_dual as select dummy from sys.x$dual where inst_id = userenv ('INSTANCE'); grant select on v_dual to public;
drop public synonym dual;

create public synonym dual for v_dual;

now try the "select 'Hello' from dual order by 1 desc;";

In case this work, please let me know.
