Installing the Discoverer tutorial EUL, data, and workbook

This section explains how to install the Discoverer tutorial EUL, data, and workbook so that you can do the Discoverer Administrator Tutorial. This procedure also installs the Video Tutorial Workbook, which is used in the Discoverer Plus Tutorial.

This section contains the following topics:

• "What must exist in the database before Discoverer Administrator tutorial users can start using the tutorial lessons?"

• "What happens when you install the Discoverer tutorial EUL, data, and workbook?"

• "What privileges do you need to install the tutorial data?"

• "What conditions apply when you connect to Discoverer Administrator for the first time?"

• "Why must you create an EUL?"

• "What steps do I follow to install the Discoverer tutorial EUL, data, and workbook?"

• "How to create a private EUL for the tutorial"

• "How to install the Discoverer tutorial"

• "How to grant access privileges to the VIDEO5 database user for the tutorial EUL"

• "How to install the tutorial business area in another End User Layer"

• "How to uninstall the tutorial business area, tables and data"

• "How to reinstall the tutorial data"

What must exist in the database before Discoverer Administrator tutorial users can start using the tutorial lessons?

Before Discoverer Administrator tutorial users can start using the tutorial lessons, the following must exist in the database:

• an End User Layer (EUL)

• the VIDEO5 database user

• the VIDEO5 data

Note: When you use Discoverer Administrator for the first time, the VIDEO5 database user might not exist. If the VIDEO5 database user does not exist, you can create it when you install the tutorial (for more information, see "How to install the Discoverer tutorial").

What happens when you install the Discoverer tutorial EUL, data, and workbook?

When you install the Discoverer EUL, data, and workbook Discoverer Administrator does the following:

• creates a new database user with a name that you specify (this user will own the EUL)

• creates a new EUL

• if the VIDEO5 database user does not already exist, Discoverer:
  • creates a new database user called VIDEO5

  • creates tutorial tables in the VIDEO5 database user's tablespace

  • populates the tutorial tables with tutorial data

• populates the new EUL with metadata about the VIDEO5 tables (i.e. it imports the tutorial business area from the file vidstr.eex, located in the \demo directory)

The following figure illustrates events that can occur when you install the tutorial.

Figure A-1 Events that can occur when you install the tutorial

Text description of the illustration tutdiag.gif

Key to the above figure:

1. Connect to Discoverer Administrator as an existing database user with sufficient privileges to install the tutorial (for more information, see "What privileges do you need to install the tutorial data?").

2. Create an EUL for a new database user.

3. If you choose to install the tutorial data in the EUL, Discoverer Administrator creates the VIDEO5 user (if not already created).

4. Discoverer Administrator creates the VIDEO5 user tables (e.g. Product, Sales Fact, Store, Time) and populates them with data from the file demodata.sql (located in the \demo directory).

5. Discoverer Administrator populates the EUL for the new database user with metadata about the video stores tutorial business area from the file vidstr.eex.

Note: If you are using a non-Oracle database, you must create the VIDEO5 database user in the database before installing the tutorial.

The choices you can make when you install the tutorial are illustrated in the figure below:

Figure A-2 Flow chart of the choices you can make when you install the Discoverer tutorial

Text description of the illustration flow.gif

What privileges do you need to install the tutorial data?

To install the tutorial data in the current EUL, the database user that you use to connect to Discoverer Administrator must have a number of database privileges:

• CREATE TABLE

• CREATE VIEW

• CREATE PROCEDURE

Hint: You can grant the above privileges to the database user by running the script <ORACLE_HOME>\discoverer\util\eulasm.sql.

• if the VIDEO5 user has not already been created, you must have the following additional database privileges:
  • CREATE USER

  • GRANT ANY PRIVILEGE

  • ALTER USER

• if you are running against an Oracle 8.1.7 (or later) Enterprise Edition database, you must also have the following additional database privileges to use the Discoverer summary management and ASM functionality:
  • CREATE ANY MATERIALIZED VIEW

  • DROP ANY MATERIALIZED VIEW

  • ALTER ANY MATERIALIZED VIEW

  • GLOBAL QUERY REWRITE

  • ANALYZE ANY

    Hint: You can grant the above privileges to the database user by running the script <ORACLE_HOME>\discoverer\util\eulasm.sql.

  • SELECT ON V_$PARAMETER

  For more information about how you grant the above database privileges, click Help.

What conditions apply when you connect to Discoverer Administrator for the first time?

When you connect to Discoverer Administrator for the first time the following conditions apply:

• you must connect as a database user having specific privileges (e.g. a DBA user to install the tutorial data)

  For more information, see "What privileges do you need to install the tutorial data?".

• no EULs or EUL metadata will exist in the database

• the VIDEO5 database user and tables will not have been created

When the VIDEO5 database user does not exist, you must create it and populate the VIDEO5 tables with tutorial data before you can begin the tutorial lessons. For more information, see "What happens when you install the Discoverer tutorial EUL, data, and workbook?".

Why must you create an EUL?

You must create an EUL (if an EUL does not already exist) to enable you to:

• install the Discoverer tutorial

• create the VIDEO5 user and populate the VIDEO5 tables with data

• complete the Discoverer Administrator tutorial

Installing the tutorial into an EUL makes the tutorial data available to all users who have access privileges to that EUL.

What steps do I follow to install the Discoverer tutorial EUL, data, and workbook?

To install the Discoverer tutorial EUL, data and workbook, follow these steps:

1. Create a private EUL - see "How to create a private EUL for the tutorial".

2. Install the Discoverer tutorial data into the private EUL that you have just created - see "How to install the Discoverer tutorial".

3. Make sure that the VIDEO5 user has the necessary privileges to access the tutorial EUL - see "How to grant access privileges to the VIDEO5 database user for the tutorial EUL".

How to create a private EUL for the tutorial

You must create an EUL if one does not already exist. To create the tutorial EUL, you must connect to Discoverer as a database user with sufficient privileges (for more information, see "What privileges do you need to install the tutorial data?") and create an EUL for a new database user.

To create the tutorial EUL:

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

2. Enter a database username with sufficient privileges (e.g. a DBA user).

   For more information, see "What privileges do you need to install the tutorial data?".

3. Enter the password.

4. In the Connect field:
   • If you are logging into your default database, leave this field blank.

     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 logging into an Oracle database that is not your default database, specify the appropriate SQL*Net connect string (for more information about the connect string, see your database administrator).

   • If you are logging into a non-Oracle database, type ODBC:<data source name>.

5. Click Connect.

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

   If no EUL exists, Discoverer Administrator displays a message asking Do you want to create an EUL now?

Text description of the illustration sec2.gif

12. Click OK to save the details and close the Privileges dialog.

    The VIDEO5 database user now has the required privileges for accessing the tutorial EUL, data and workbook.

How to install the tutorial business area in another End User Layer

Having installed the tutorial business area into one EUL, you can install it in other EULs (for more information, see "How to install the Discoverer tutorial").

If you want users to have access to the tutorial business area but not to the EUL in which you originally installed the tutorial, you can install the tutorial in one (or more) alternative EULs to enable each EUL owner to have their own tutorial business area. Each time you install the tutorial in a different EUL, another tutorial business area is created in that EUL. Note that every tutorial business area accesses data from the same set of tables in the database. Only one version of each table is created in the database (i.e. in the VIDEO5 database user's tablespace).

To install the tutorial business area in another EUL:

1. Connect to Discoverer Administrator as the database user that owns the EUL in which you want to install the tutorial (for more information, see Chapter , "Exercise 1: Connecting to Discoverer Administrator").

   Note: Make sure that the database user you connect with has sufficient privileges to install the tutorial (for more information, see "What privileges do you need to install the tutorial data?")
