Problem to connect as SYS

edited Oct 8, 2009 4:37PM in Database Security Products (MOSC) 10 commentsAnswered
 I am trying to connect as sys.     1. When trying from sqlplus running under windows maching  (sys/manager@proddb as sysdba) getting error
        ORA-12560: TNS:protocol adapter error
   
  2. When trying from putty running in same windows maching  (sys/manager@proddb as sysdba) getting error
       ORA-12560: TNS:protocol adapter error
       ORA-01017: invalid username/password; logon denied

     But using putty when trying without conneting string (sys/manager as sysdba) , I can succefully login. But few days ago I can login both ways ( with or without connecting string). From when or why this problem started I don't know. Can any one help me?

Thanks in advance
