I was looking at this RMAN script. I see these commands:

STARTUP FORCE MOUNT
ALTER DATABASE MOUNT STARTUP FORCE shuts it down and then restarts it and mounts it. So, why the ALTER DATABASE MOUNT?

   STARTUP FORCE MOUNT;
RESTORE CONTROLFILE;
   ALTER DATABASE MOUNT;
RESTORE DATABASE;
RECOVER DATABASE;
ALTER DATABASE OPEN RESETLOGS; Received on Fri Aug 13 2010 - 12:47:00 CDT
