Moving db to linuxSorry, 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

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
