HP/UX 11.00 Oracle

Here is an interesting one guys; I need to re-create our production database in a development environment. I am limited to import/export due to the fact that BMC Patrol is not installed on the new server and Oracle Management Server is not either, so that rules out OEM.

Mainly what I want to do is a full export and import but limit the amount of data that is imported into development. Some of the tables in production have 43 million rows and I only need a fraction of that. I know I can grab the DDL with a full export but how bout the rest?

Thanks in advance;
