14 Click on ok INSTALL A DBCA GIVE A PASSWORD AND UNLOCK THE ACCOUNT:

15 CLICK ON OK AND EXIT Configuring the repository and workspaces 1. We are going to use the Repository Assistant application to configure the repository, create a workspace, and create the objects in the repository that are needed for OWB to run. 2. The Repository Assistant application is available from the Start Menu under the Warehouse Builder Administration submenu of the Oracle program group as shown here: 3.

16 CLICK ON REPOSITORY ASSISTENCE THEN CLICK ON NEXT We ll launch the Repository Assistant application on the server (the only machine we ve installed it on) and the first step it is going to ask us for is the database connection information Host Name, Port Number, and Oracle Service Name or a Net Service Name for a SQL*Net connection. Determining what port your listener is listening on Open a command prompt window and type in the following command: C:\>lsnrctl LSNRCTL> status Finding your database instance name window and type in the following command: C:\>lsnrctl

17 LSNRCTL> service 2. Now that we ve determined the connection information for our database, we ll move along to step 2 of Repository Assistant. It asks us what option we d like to perform of the following: Manage Warehouse Builder workspaces Manage Warehouse Builder workspace users Add display languages to repository Upgrade Repository to current release of Warehouse Builder Manage J2EE User account Manage Optional Features We re going to select the first option to manage workspaces and move along to the next step. This step asks us what we d like to do with workspaces: create a new workspace or drop an existing one.
