12. 9-12 Copyright © 2004, Oracle. All rights reserved. Configuring Migration Workbench To configure Migration Workbench: 1.Create a Workbench repository user in the database for the Oracle Database Repository option only. 2.Start the Migration Workbench application. 3.Choose a Workbench repository option. 4.Create the Workbench repository tables. 5.Select the migration source.

13. 9-13 Copyright © 2004, Oracle. All rights reserved. Step 1: Creating a Workbench Repository User in the Database If you choose an Oracle database as the repository, you must first create a Workbench repository user in the database: Create a user account, for example, Username: rep_user, Password: rep_user. Assign CONNECT and RESOURCE roles to the user account. Create and assign separate default tablespace with at least 30 MB of disk space to the user account.

14. 9-14 Copyright © 2004, Oracle. All rights reserved. Step 2: Starting the Migration Workbench Application To start the Migration Workbench application, run the omwb.bat file that is located in the following directory: \omwb\bin. For example: E:\oracle\Omwb\bin>omwb.bat
