You could always do a startup force.

This is the same (I think it is anyway) as a shutdown abort/startup.

The difference is that the rollback takes place in the background after the database has opened.

Long ago this was somewhat problematic as the rollback would be serialized. eg. if your rollback would have been in parallel normally, the startup force method would
cause the rollback to be done in a single process, taking much longer to complete.

I haven't looked at that in some time, so I don't know how it behaves now. If might be worth
some reading and experimentation.
