ORA-00217

Error: ORA-00217: controlfile could not be resized for migration from 9.0.1

Causa: Controlfiles created by release 9.0.1 were missing some records. These records are automatically added by resizing the controlfile when attempting to run a later release. The resize failed.

Acción: Look in the alert log for the reason the resize failed. If it can be fixed by giving the controlfile more space, then do that. Otherwise, use the CREATE CONTROLFILE script dumpped to the trace file to create a new controlfile.
