Lesson 1: Creating a private End User Layer

## Lesson 1: Creating a private End User Layer for a new tutorial database user

It will probably take you about 5 minutes to complete this lesson.

In this lesson you will create a private End User Layer (EUL) for a new tutorial database user.

Each tutorial database user has their own EUL. This enables each tutorial database user to create their own version of a Discoverer Administrator business area.

The VIDEO5 user, tables and tutorial data must have been installed by your Discoverer manager before you can complete the tutorial (for more information, see Appendix A, "Installing the Discoverer tutorial EUL, data, and workbook").

This lesson consists of the following exercise:

- "Exercise 1: Creating a private End User Layer for a new tutorial database user"

### Exercise 1: Creating a private End User Layer for a new tutorial database user

In this exercise you will create a private end user layer for a new tutorial database user. The tutorial database user that you create in this exercise you will use in the other tutorial lessons.

To create a private End User Layer for a new tutorial database user:

1. Choose Programs | Oracle Developer Suite - <HOME_NAME> | Discoverer Administrator from the Windows Start menu to display the Connect dialog.

1. Enter a database user with DBA privileges (for more information about the DBA username and password, see your database administrator).

2. Enter the database user password in the Password field.

3. In the Connect field:

   - If you are connecting to a default database, leave this field blank and click Connect.

     With Oracle 8.1.7 (or later) Enterprise Edition databases an entry is required in your tnsnames.ora file for this to work (for more information, see your Discoverer manager).

   - If you are connecting to an Oracle database that is not your default database, specify the appropriate SQL*Net connect string and click Connect (for more information about the connect string, see your database administrator).

   - If you are connecting to a non-Oracle database, type ODBC:<data source name> and click Connect.

4. To display the EUL Manager dialog:

   Discoverer Administrator behaves differently depending on whether an EUL has already been created for the database user that you use to connect with.

   - If no End User Layers exist, Discoverer Administrator displays a dialog with the message Do you want to create an EUL now? Click Yes to display the EUL Manager dialog.

   - If one or more End User Layers exist, Discoverer Administrator displays the Load Wizard. Click Cancel in the Load Wizard and choose Tools | EUL Manager to display the EUL Manager dialog.

   #### Figure 2-2 EUL Manager dialog

   1. Click Create an EUL to display the Create EUL Wizard dialog.

   #### Figure 2-3 Create EUL Wizard dialog

   Use this wizard to create an EUL and a new database user. You will use the new database user for all the lessons in this tutorial.

   1. Select the Create a new user radio button.

   2. Clear the following check boxes:

      - Grant access to PUBLIC

      - New EUL is for use by Oracle Applications users ONLY

   3. Type `admintutor` followed by your by your initials (e.g. `admintutorjs` if your name is John Smith) in the User field.

      This will be your database username for the tutorial.

   4. Enter the same username that you entered in the User field, in both the Password and Confirm Password fields.

   5. Make sure that the Create EUL Wizard dialog displays the settings for radio buttons and check boxes as shown below.

   #### Figure 2-4 Create EUL Wizard dialog

   1. Click Next to display the Create EUL Wizard: Step 2 dialog.

   #### Figure 2-5 Create EUL Wizard: Step 2 dialog

   Text description of the illustration eulwz2.gif

   1. Select the default and temporary tablespaces.

      For example, select USER_DATA, as the default tablespace and TEMP as your temporary tablespace. If you are in doubt about selecting a default and temporary tablespace, see your database administrator.

   #### Figure 2-6 Create EUL Wizard: Step 2 dialog

   Text description of the illustration eulwiz2.gif

   1. Click Finish for Discoverer Administrator to build the EUL.

      Discoverer Administrator displays a progress bar showing the creating EUL status.

   #### Figure 2-7 Creating EUL progress bar

   Text description of the illustration eulprog.gif

   Once Discoverer has created the new EUL Discoverer Administrator displays a message that the EUL has been created successfully.

   #### Figure 2-8 EUL created successfully message

   Text description of the illustration eulsuc.gif

   Note: The following steps enable you to close Discoverer Administrator by navigating through a series of dialogs. This help you to start the other tutorial lessons from a common starting point.

   1. Click OK to display the following dialog.

   #### Figure 2-9 Install tutorial data in EUL dialog

   Text description of the illustration instut.gif

   1. Click No, Discoverer Administrator displays the following dialog.

      Note: The reason you are asked to click No is because the tutorial data has already been installed by your Discoverer manager. For more information, see your Discoverer manager or Appendix A, "Installing the Discoverer tutorial EUL, data, and workbook".

   #### Figure 2-10 Do you want to connect as the owner of the EUL you just created? dialog

   In this exercise you have created a private end user layer for a new tutorial database user.

   ## Lesson summary

   In this lesson you:

   - created a private EUL for a new tutorial database user

   Having created a new EUL for a new tutorial database user you can now complete the tutorial lessons in the following chapters.

   In the next lesson you will create a business area, described in "Lesson 2: Connecting to Discoverer Administrator, using the Load Wizard and the Workarea".
