January 2006

Welcome to Oracle Database Express Edition (Oracle Database XE)! This tutorial gets you quickly up and running using Oracle Database XE by creating a simple application. This guide covers the following topics:

1 Logging in as the Database Administrator

The first thing you need to do is to log in as the Oracle Database XE Administrator. Follow these steps:

  1. Open the Database Home Page login window:

    • On Windows, from the Start menu, select Programs (or All Programs), then Oracle Database 10g Express Edition, and then Go To Database Home Page.

    • On Linux, click the Application menu (on Gnome) or the K menu (on KDE), then point to Oracle Database 10g Express Edition, and then Go To Database Home Page.

  2. At the Database Home Page login window, enter the following information:

    • Username: Enter system for the user name.

    • Password: Enter the password that was specified when Oracle Database XE was installed.

  3. Click Login.

    The Oracle Database XE home page appears.

2 Unlocking the Sample User Account

To create your application, you need to log in as a database user. Oracle Database XE comes with a sample database user called HR. This user owns a number of database tables in a sample schema that can be used to create applications for a fictional Human Resources department. However, for security reasons, this user's account is locked. You need to unlock this account before you can build a sample application.

To unlock the sample user account:

  1. Make sure you are still logged on as the database administrator, as described in the previous section.

  2. Click the Administration icon, and then click Database Users.

  3. Click the HR schema icon to display the user information for HR.

  4. Under Manage Database User, enter the following settings:

    • Password and Confirm Password: Enter hr for the password.

    • Account Status: Select Unlocked.

    • Roles: Ensure that both CONNECT and RESOURCE are enabled.

  5. Click Alter User.

Now you are ready to create your first application.

3 Logging in as the Sample User Account

To log in as the sample user account:

  1. Log out from the database administrator account by clicking Logout in the upper right corner of the Database Home Page.

  2. In the window, click Login.

  3. In the Login window, enter hr for both the user name and password.

  4. Click Login.

    The Database Home Page appears.

4 Creating a Simple Application

Creating an application is an easy way to view and edit your database data. You create this application based on the EMPLOYEES table, which is part of the HR schema.

To create an application based on the EMPLOYEES table:

  1. On the Database Home Page, click the Application Builder icon.

  2. Click the Create button.

  3. Under Create Application, select Create Application and click Next.

  4. Under Create Application:

    1. Name: Enter MyApp.

    2. Accept the remaining defaults.

    3. Click Next.

    Next, add pages to your application.

  5. Under Add Page:

    1. For Select Page Type, select Report and Form.

      Report and Form icon

      Notice that Action describes the type of page you are adding.

    2. Next to the Table Name field, click the up arrow, and then select EMPLOYEES from the Search Dialog window.

    3. Click Add Page.

      Two new pages display at the top of the page, under Create Application.

    4. Click Next.

  6. On the Tabs panel, accept the default (One Level of Tabs) and click Next.

  7. On the Shared Components panel, accept the default (No) and click Next.

    This option enables you to import shared components from another application. Shared components are common elements that can display or be applied on any page within an application.

  8. For Authentication Scheme, Language, and User Language Preference Derived From, accept the defaults and click Next.

  9. For the theme, select Theme 2 click Next.

    Themes are collections of templates that you can use to define the layout and style of an entire application.

  10. Confirm your selections. To return to a previous wizard page, click Previous. To accept your selections, click Create.

    After you click Create, the following message displays at the top of the page: 

    Application created successfully.

5 Running Your New Application

To run your application:

  1. Click the Run Application icon.

    Run Application icon

  2. In the log in page, enter hr for both the User Name and Password.

    Your application appears, showing the EMPLOYEES table.

  3. Explore your application.

    You can query the EMPLOYEES table, if you want. To manage the application, use the Developer toolbar at the bottom on the page.

    The Developer toolbar offers a quick way to edit the current page, create a new page, control, or component, view session state, or toggle debugging or edit links on and off.

  4. To exit your application and return to Application Builder, click Edit Page 1 on the Developer toolbar.

  5. To return to the Database Home Page, select the Home breadcrumb at the top of the page.
