Go to the START Menu as shown in the following image:-
The first step is to specify what action to take
1. Since we do not have a database created, we’ll select the Create a Database option
2. If there was a database already created, the options for configuring a database or
deleting a database would be selectable
3. Templates can be managed with the Database Configuration Assistant application, which
are files containing preset options for various database configurations.

This step will offer the following three options for a database template to select:
° General Purpose or Transaction Processing
° Custom Database
° Data Warehouse
NOTE:-BUT WE HAVE TO SELECT A CUSTOM DATABASE
This step of the database creation will ask for a database name.
This step of the database creation process asks whether we want to configure Enterprise

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

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.

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.

19. Roll No: Subject: Dataware Housing Date:
This brings us to step 4 of the process, which is to specify an owner for the workspace
This step will depend on which option we specified in step 4. If we are creating a new user,
it will ask us for an existing user with DBA privileges in the database.
