Assuming that the application "knows" the real username, let the first thing that the app does is call dbms_application_info.set_client_info passing the real username as a parameter. This sets v$session.client_info to the real username.

T10-PARTS> select client_info from v$session 2 where sid = (select sid from v$mystat where rownum = 1) ;

CLIENT_INFO

T10-PARTS> execute dbms_application_info.set_client_info('REAL_USER_NAME');

PL/SQL procedure successfully completed.

T10-PARTS> select client_info from v$session 2 where sid = (select sid from v$mystat where rownum = 1) ;

CLIENT_INFO

REAL_USER_NAME T10-PARTS> select userenv('CLIENT_INFO') from dual;

USERENV('CLIENT_INFO')

REAL_USER_NAME T10-PARTS> select sys_context('userenv', 'client_info') from dual;

SYS_CONTEXT('USERENV','CLIENT_INFO')

REAL_USER_NAME Hope this helps

Paul

Dear Gurus , I have a comic question . ? We have a db and ias and portal . users log in by using portal login page . The problem is : because application server connects to db , in v$session the machines are all the application server machine . Although the users are db users , when you login from portal , the usernames are portal30 and portal30_sso ..

So how will I know which user is which session ? V$session gives no help ...

May be comic :) But can not find an answer .. Investigating portal for writing into v$session as the real username ..But no other thing comes into my mind ....

Any idea please ...
