Hi,  
  As we all know, when a user connects  to database with 'AS SYSDBA' option, no 
matter what his account name is,the value of  
'sys_context('userenv','session_user') is alway 'sys',then if i execute my 
access control based 'sys',why the policy does not work? 
   
    Then,how can I exectute access control to users those connect to database 
with option'AS SYSDBA'?
