Frequently asked questions

This section answers frequently asked questions about starting Discoverer, and contains the following topics:

What is the End User Layer (EUL)?

The EUL is an intuitive, business-focused view of the database that uses terms that you are familiar with and can easily understand. The EUL insulates you from the complexity usually associated with databases. This enables you to focus on business issues instead of data access issues.

What are database accounts?

To use Discoverer, you need a database account that enables you to connect to Discoverer. You store database account details in a Discoverer connection along with EUL and language settings.

Note: If your organization uses Single Sign-on (a system for enabling users to log in once to access many different applications), you also need a Single Sign-on account. If you are not sure whether your organization uses Single Sign-on, contact the Discoverer manager. For more information, see "What is Single Sign-on?".

A database account comprises two pieces of information:

  • A user name - a short name by which you are identified in the database. For example, jchan, or marketing.

  • A password - a secret key that you use to authenticate your user name. An initial temporary password is created for you by the Discoverer manager. To keep your organization's data secure, do not tell another person what your password is, or write down your password so that other people can read it (for more information, see "When and why do I need to change my password?").

How do I create and save login information in a Discoverer connection?

You create and save login information in a new private Discoverer connection when you want to start Discoverer using login details that you have not saved previously.

To create and save login information in a Discoverer connection:

  1. Display the Discoverer connections page (for more information, see "How to display the Discoverer Plus connections page").

  2. Click Create Connection to display the Create Connection: Connection Details page.

  3. Click Yes at the confirmation page to delete the connection and return to the Connect to OracleBI Discoveer page.

Notes

  • You can only delete private connections that you have created yourself. You cannot delete public connections created by the Discoverer manager.

What are public connections?

Public connections are Discoverer logins created by the Discoverer manager. Public connections enable you to start Discoverer and access workbooks without having to create your own connections.

You cannot edit or delete public connections. Only the Discoverer manager can create, edit, and delete public connections.

What are user-defined connections?

User-defined connections (also known as private connections) are Discoverer logins that you create yourself. You can edit and delete private connections. Only you can access, edit, and delete the private connections that you create.

When and why do I need to change my password?

Typically you will have to change your password periodically to maintain data security.

Your system manager specifies how long you can keep the same password before it expires. In other words, how long you can keep the password before you have to change it.

You will know your password has expired if you start Discoverer and are prompted to enter a new password. When you connect to Discoverer, you might be warned that your password will expire in a specified number of days. If you do not change the password in this period, you are prompted to enter a new password when the password expires.

It is also important to change your password if you think that someone else has found out what the password is.

How do I change the password for a connection?

You change the password for a connection when the password:

  • has expired

  • is about to expire

  • has become known by another user

To change the password for a connection:

  1. Display the Discoverer Plus connections page (for more information, see "How to display the Discoverer Plus connections page").

  2. Click the Update icon next to the connection for which you want to change the password.

  3. Click Change Database Password.

  4. In the Password field, enter the current database password for the current user name.

  5. In the New Password field, enter a new database password for the current user name.

  6. In the Verify Password field, re-enter the new database password for the current user name.

  7. Click Finish.

    The Connect to OracleBI Discoveer page is displayed. You can now use the connection to start Discoverer.

Notes

  • If any of the password details that you entered were invalid, an error message is displayed with advice on which value to change.

How do I change the End User Layer for a Discoverer connection?

You change the End User Layer (EUL) for a Discoverer connection when you want the connection to start Discoverer using a different EUL (for more information, see "What is the End User Layer (EUL)?").

To change the EUL for a Discoverer connection:

  1. Display the Discoverer Plus connections page (for more information, see "How to display the Discoverer Plus connections page").

  2. Click the Update icon next to the connection for which you want to change the End User Layer.

  3. In the Password field, enter a valid password for the Discoverer connection.

  4. Click Continue.

  5. If the user name for the current Discoverer connection has access to more than one End User Layer, the Select End User Layer for Discoverer Connection page is displayed. Do the following:

    1. Select an End User Layer from the End User Layer drop down list.

    2. Click Finish.

    The Connect to OracleBI Discoveer page is displayed. You can now use the connection to start Discoverer.

Notes

  • If the user name does not have access to more than one End User Layer, you cannot change the default End User Layer.

  • If the password that you entered was invalid, an error message is displayed with advice on which value to change.

What is Single Sign-on?

Oracle Application Server Single Sign-On enables users to access multiple Oracle Application Server applications (e.g. OracleBI Discoverer) with a single password. Using Single Sign-On, users can log in to Oracle Application Server and gain access to all applications for which they are authorized, without requiring them to re-enter a user name and password for each application.

What is the difference between Single Sign-on and Discoverer passwords?

If your organization uses Single Sign-on, your Discoverer password is separate to your Single Sign-on password:

  • your Single Sign-on password authenticates your Single Sign-on user name

  • your database password authenticates your database user name

  • with a single Sign-on connection, you can connect using many different Discoverer connections

How do I know what Single Sign-on ID is being used in Discoverer Plus?

To find out the Single Sign-on ID being used in Discoverer Plus, choose Help | About Discoverer to display the About OracleBI Discoverer dialog, and look in the Connected As area.
