DBA_ORPHAN_KEY_TABLE

DBA_ORPHAN_KEY_TABLE reports key values from indexes where the underlying base table has block corruptions. To create the view, run the DBMS_REPAIR.ADMIN_TABLES procedure. To populate the orphan key table for an index, run the DBMS_REPAIR.DUMP_ORPHAN_KEYS procedure on the index. For each key in the index that points to a corrupt data block, Oracle inserts a row into the orphan key table.
