goal_name is different andso is length of string

select of quoted string has different lengths in 2 databases.

DB1 :

SQL> select 'kk' from dual;

'k

--
kk

DB2 :

SQL> select 'kk' from dual;



'kk'

--------------------------------
kk

I tried 3 different Unix server ( sloaris 5.8) and 4 databases of
different version ( 8.1.7.4 and 9.2.0.4 -- 2 each) on each server. The
only common factor for databases to fall in the group was
global_names. DB1 group had global_names = TRUE and DB2 group had
global_name = FALSE.

Can someone help in understanding why it is so. Or do I have to look
something different.....
