Data export and import between Oracle 9 and 10

Question

Hi all,
I have been working with this for weeks. Reading posts and oracle doc. Finally, bugs block my way. Hope you can help me out. Many Thanks.
Situation: I need to export data of one table from Oracle 10.2.0.1 to Oracle 9.2.0.8
Background: Oracle 10.2.0.1 at Machine 1(IBM AIX), Oracle 9.2.0.8 at Machine 2(don't know, maybe Stratus), My local Machine(XP)
Method 1: using SQL developer (MWB)
Bug: there is CLOB field in the target table. All content of CLOB field become "(CLOB)" and data lost. This is a logged bug.
Solution: give up using SQL developer
Method 2: using Oracle 10 client exp & imp and remote from my local machine XP
Bug: PLS-00302-SET_NO_OUTLINES must be declared
Solution: using Oracle 9 client
Method 3: using Oracle 9.2.0.1 client, since my local machine is XP
Bug: EXP-00003: no storage definition found for segment (target DB run Oracle 9.2.0.8)
Solution: using Oracle 9.2.0.8 client
Problem: Oracle 9.2.0.8 client is for Stratus x86 only? I have no idea what Stratus is except believing it is a server machine.
My senior told me to use sqlldr. But I just used it once for 3rd party DB for import. Can sqlldr export data?
I would like to ask for any suggestions or/and solutions. Many Thanks!
Best regards,
Philip

Hi OrionNet,
Thank you very much for your helping and my problem solved. Here is my version of spool setting modifying from OrionNet example.
set echo off
set newpage 0
set space 0
set pagesize 0
set long 2000000 //this is for CLOB, set it enough large to avoid missing data
set feed off
set head off
set trimout on
set trimspool on
spool C:\spool.dat
SELECT col1||'<EOFD>'||col2||'<EOFD>'||col3||'<EORD>' //this is separator for sqlldr
FROM tab1
WHERE col2 = 'XYZ';
spool off
and control file for sqlldr
load data
infile 'spool.dat' "str '<EORD>'" //ROW separator
append
into table tab1
fields terminated by '<EOFD>' //FIELD separator
trailing nullcols
col1,
col2,
col3
I think that using spool and sqlldr is the most "painless" method for Oracle 10g to 9i data move unless you are DBA of both DBs.
Please share If anyone have easier/safer method. I am just crazy to migrate backward Oracle version.
Thanks again,
