Startup force is a shorthand method of issuing:

      shutdown abort
      startup

(per
http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:1309402207602 )

When you are implementing VCS, you are indicating that you want uptime. You don't want an interminable wait while Oracle tidies stuff up. You want it to come down immediately on the current server, and then be available as quickly as possible on the other server. This will allow the other applications that rely on Oracle to become available again in the shortest possible time.

    As far as shutdown abort, this issue has been discussed many times on this list and the answer has always been that it is safe in the current versions of Oracle. Yes, a novice DBA should not use it before doing a cold backup (you need to do a startup followed by a more normal shutdown), but that is not the situation with VCS switching Oracle to another server in your cluster.
