RE: Recover an unrecoverable database

Dan - May be a good Oracle Support question. I've had pretty good luck with them on really challenging recoveries. My suggestion would be to try again. Load the files again from tape, but allow recovery when the database comes up. Since the database was shutdown abort, Oracle will want to automatically recover the database when it tries to start. The recovery information is probably in the redo logs (good reason to back them up).

Here's the scenario - A backup was done of a database that had been shutdown with the abort option. The redo logs (no archiving) are also backed up. The controlfiles have since been lost.
Business request - Retrieve a schema that has since been dropped from the database.  

Attempted solution - restore the backups, open the db without performing recovery (resetlogs and readonly corruption allowed). Unfortunately, this resulted in an ORA-00600 when it attempted to read the SYSTEM datafile.  

Does anyone have any ideas of how to open this db so we can get the data out of the schema? We don't care if it is not consistent.
