There are a couple of real basic questions. (Maybe three.)
1. You do have a recent full database backup? 2. You are archiving the redo log files? 3. Was this a "batch" process that can be redone or was it online.
With that info, you should be able to read Chapter 19 (Recovering a Database) in the Administrator's Guide to get the options available for your specific situation.
In general, your first action should have been to start the instance and then mount the database without opening the files. Then follow the appropriate recovery steps.
At this point, given that you have done some things to the database, you may have no other choice than to restore and roll forward to the crash point.
