UpGrade Oracle 8xx to 9xx, during the Database Upgrade Assistant (DUA) it mentioned ORA-xxx, which requires few files to be restore.
Try restore from tape but the result was the files is corrupted.

FYI - forgotten to do off-line backup before the upgrade.

Is there any way or tips to start the system with tapes (online tapes) without to do or install the system fresh (start from scratch).
