Opening an Oracle database with a corrupted redo log I have a database that is not open. And I have a redo log that is corrupted.

What would be the best way for me to open the database? This is a testing db and I am not concerned with data loss - but I need to get the database open and working again.

Some additional notes:
Trying to switch logs tells me that the log is required for recovery
Attempting to recover fails
Trying to open gives the error msg that the log is corrupted

Additional clarification:
I do need some of the data in the db; but I don't need any of the recent data (about a year worth of data). There is some configuration data which I do want.
I don't know the structure of the db, and I have no script to re-create it.
What you are looking for is to clear the redo log. 

ALTER DATABASE CLEAR LOGFILE GROUP #;
