Export Oracle 10g and Import to Oracle 9i

I have a data warehouse server that's running Redhat AS 2.1 and Oracle 9.2.0.4, and a production database that's running Redhat AS 4.0 and Oracle 10.2.0.3. I need to export tables from the Oracle 10g database and import them into the Oracle 9i database. The Oracle 10g server/database is new. I know I need to use the Oracle 9i exp command to export the data from the Oracle 10 databse, but don't know all the steps needed to do this. I'm a part-time dba so I would appreciate clear/detailed steps on how to get the two servers to talk to each other, and then how to use the exp command from the Oracle 9 server. The documentation I found said to invoke the exp command on the lower version machine using: EXP user/password@tnsname arguments... I'm really not sure how to get the new server in the tnsnames on the lower Oracle 9 version. I need to do a full export from the Oracle 10 database. Any help would be greatly appreciated. Thanks!

Thanks. We'll let you know when a new response is added.

If you have 10g and 9i clients installed on the same workstation, open up each tnsnames.ora file using notepad and copy the tns entry for your 10g server into your 9i tnsnames.ora. Save the file, then make sure your Oracle Home is set to your 9i directory. You should be able to connect to the 10g server from your 9i directory and run your export.
