ORA-01031 Insufficient privilege when connecting from client

[samdba]

Hi Supower,

Thank you very much.

My problem got resolved with your help.

I have also kept the SQL.AUTHENTICATION... in sqlnet.ora because without that it was giving problem in starting the database where I use connect internal/intpwd as sysdba;

I did the foll. to fix the problem.

1. Shutdown database, its services
2. Rename existing password file.
3. create the new password file with internal password.
4. Connect to internal as sysdba.
5. alter user sys identified by syspwd;
6. grant sysdba to sys;
7. alter user system identified by systempwd;
8. grant sysdba to system;

After this, I am now able to connect to sys and system as sysdba.

Thanks a lot.
