Hi Supower,

Here is the situation.

#SQLNET.AUTHENTICATION_SERVICES= (NTS) in sqlnet.ora.

I had to recreate password file with internal password instead of sys because my database startup script stopped working as I am using internal for starting the DB.

Now, I am able to connect internal as sysdba but not to sys as sysdba. So, what happens is whatever password I use in creating the oracle password file, it is able to connect as sysdba.

Now even with commented SQLNET.AUTHENTICATION... I am not able to connect to sys or system as sysdba.

I think the password file is more important here.

What should I do now?

Thanks,
