ORACLE 7 TABLE/INDEX LOCK QUESTION

Hello,

        I've killed an active session from the database (ORACLE 7.2.3) because a

    user was executing an abnormally large insert transaction.     This same transaction seemed to have locks on     a table and it's indexes. After the session was killed     the database was rolling back this huge transaction, but     the indexes and the table were still locked.

        Is there any way I can force oracle to release the locks     without waiting for the entire transaction to rollback.

                                                Thanks in advance,
                                                                    -
