10gR2 cannot startup ORA-01092 + ORA-00704 + ORA-39700

Hello, I cannot startup a newly created 10gR2.
I use the same scripts that perfectly worked on 10gR1.
(Solaris 10)

At database open time I get:
ORA-01092: ORACLE instance terminated. Disconnection forced

In the used dump directory there is this message:
ORA-00704: bootstrap process failure
ORA-39700: database must be opened with UPGRADE option
This is the whole dump file:

Any suggestion?
Thanks,

Explanation:
This is a general error reported at startup when there is some
problem during processing of bootstrap information.

There should be an accompanying error/s.

Diagnosis:
- See the accompanying error/s for more information.

- Shutdown abort the instance and clean up any OS structures
used by the instance. Eg: Ensure there is no shared memory,
semaphores etc.. left lying around

- Retry the startup.

- If the error persists follow up on the accompanying errors
(Eg: block corruption etc.. could cause this.)
