Hi,

I have a 10.1.0.4 installed on windows, it uses password file, and ORA_DBA local group is created which contains the local user I use to login. I can use sqlplus / as sysdba to login.

Then I upgrade it to 10.2.0.3, the following is how I did it:

1. install 10.2.0.1 software on a new oracle home
2. install 10.2.0.3 patchset on top of it
3. use database upgrade assistant (DBUA) graphic tool to upgrade the database

After that, I can no longer login using sqlplus / as sysdba, I have to use sqlplus sys/xxxxx as sysdba instead, which violates our company's security policy. How can I make sqlplus / as sysdba work again?

Thanks a lot!
