Error EXP-00003 handling when Oracle EXP exports database

The "Exp-00003:no storage definition found for segment ..." error occurs when you export a table with a LOB object using the previous version of EXP from version 9205 (or more).
This is a bug for Oracle, and for this bug, the following processing can be done to successfully export the data.
Run under the SYS user of the target database:

CREATE OR REPLACE VIEW Exu9tne (
Tsno, Fileno, Blockno, length) as
SELECT ts#, segfile#, segblock#, length
From sys.uet$
WHERE ext# = 1
UNION All
SELECT * from SYS. Exu9tneb
/

Export operation, after the completion of exp, it is best to restore the view (Metalink recommended).

CREATE OR REPLACE VIEW Exu9tne (
Tsno, Fileno, Blockno, length) as
SELECT ts#, segfile#, segblock#, length
From sys.uet$
WHERE ext# = 1
/
