Export Utility

As an Oracle DBA, you will find yourself using the Export utility in many situations; one example is rolling out production databases. For instance, you can use the Export utility to create a base-level database schema. Then, when you go to a customer site, you will be able to create a blank database and import your database definitions and base-level data. This will help ensure that all current database objects are created and will help minimize installation errors.
