Thanks for the response. There was a key fact missing from what I told you, sorry. The HP database is in a computer room connected by a pair of T1's to our computer room. With an aggregate throughput orf 3.08 Mb / sec. I had thought that any sort of sql copy or ctas type solution would be out because of the bandwidth requirements.
Sorry again,
Allan

Sorry, I didn't see the HP-UX part in beginning of your mail.
Yep, you have to go with exp-imp for changing platforms.
I'd go with exp-imp with rows=n indexes=n constraints=n and transfer all data over dblink. After which I'd run modified create index statements on tables followed by imp constraints=y.
Here's a simple query for generating insert commands over database link (you might want to remove parallel hint and use several serial inserts instead):
set linesize 300
set pagesize 0
set feedback off
set trimspool on
spool /tmp/apps_insert.sql
prompt alter session enable parallel dml;;
select 'insert /*+ APPEND PARALLEL(' || table_name || ',4) NOLOGGING */ into '
|| owner || '.' || table_name
|| ' select * from ' || owner || '.' || table_name || '@dblink;'
from dba_tables
where owner in ('AP', 'APPLSYS', 'APPS', 'AR', 'GL', 'JE')
order by owner;
spool off
exit
Tanel.

Hi
Who told you you have to use exp-imp for that?
Since the platform remains the same, you can use regular migration path to go from 8i to 9i.

Im, going to be moving a 220 GB 8.1.7.4 database from HP-UX to Red Hat AS 3.0 running 9.2.0.4.0. I'm told that we have to use export/import to get that job done. I plan to work through pipes and use split to keep the file sizes to 2 GB or less to aviod large file issues between the platforms. Does anyone know of other issues that may trip me up?
Thanks In Advance
