I'm facing a problem with the Oracle 10 database. This is a RAC configuration and live system. After restarting the CRS in both servers, the database does not go to OPEN:

ERROR at line 1:
ORA-01219: database not open: queries allowed on fixed tables/views only

SQL> select status from V$instance;

If you run manually either:

SQL> alter database open;


SQL> startup force;

The instances go OPEN and everything works normally, but if you restart the CRS again, the same problem, the database does not go to OPEN.
I guess something is missing/wrong in an Oracle conf file...

Can someone help me out in this please?

Thanks in advance.
