Sometimes you can enter recover database;, then tell it to use a redo log to do the recovery when it prompts for an archive log. Doesnt always work, but it works sometimes. However, if you opened it with allow_resetlogs_corruption, it may be too late. Oracle says that once you do that, you must export your data and re-create the database.
