Oracle 9i export large Oracle 10g Fields

############################ Error symptom: ###############################
The following error occurs when exporting data with 9i exp:

F: \ Oracle \ bin> exp wssw/foresee @ cradle203 file = d: \ sb_sbxx_zb.dmp tables = sb_sbxx_zb

Export: Release 9.2.0.1.0-Production on Friday May 27 11:15:24 2011

With the Partitioning, OLAP and Data Mining options
The ZHS16GBK and AL16UTF16 NCHAR character sets have been exported.

To export the specified table, use the regular path...

EXP-00003: storage definitions for segments (6,) not found
The export is successfully terminated, but a warning is displayed.

######################################## #################################

View metalink and find that this error will occur as long as the exp before 9.2.0.5 is used to export tables with LOB fields in the database after 9.2.0.5.
Solution:
1. Upgrade the client to 9.2.0.5 or above.
I used exp of 9208/10. 1.0.4 to export a table containing BLOB and CLOB. All data can be exported!

2. alternative solution:
Connect to the SYS user before export and run the following SQL:

Create or replace view exu9tne (
Tsno, fileno, blockno, length)
SELECT ts #, segfile #, segblock #, length
FROM sys. uet $
WHERE ext # = 1
UNION ALL
SELECT * from sys. EXU9TNEB

After the export is complete, restore the view (the definition can be seen through user_views). The definition of oracle9i and oracle10g is the same:

Create or replace view exu9tne (
Tsno, fileno, blockno, length)
SELECT ts #, segfile #, segblock #, length
FROM sys. uet $
WHERE ext # = 1

You can import data normally during 9i import without any errors.
