1 Introducing Oracle BI Discoverer and Oracle Portal

Oracle BI Discoverer allows you to publish Discoverer Worksheet content on various Portals, such as Oracle Portal, Oracle WebCenter Portal and Oracle WebLogic Portal.

This chapter introduces you to Oracle BI Discoverer and Oracle Portal and contains the following topics:

1.1 What is Oracle Business Intelligence Discoverer?

Oracle Business Intelligence Discoverer is an intuitive ad-hoc query, reporting, analysis, and Web publishing toolset that gives business users immediate access to information in databases.

Oracle Business Intelligence Discoverer enables business users at all levels of the organization to make faster and more informed business decisions. Using any standard Web browser, you have secure and immediate access to data from both relational and multidimensional data sources. Oracle Business Intelligence Discoverer provides a business view to hide the complexity of the underlying data structures, enabling you to focus on solving business problems.

Oracle Business Intelligence Discoverer comprises several integrated components that work with the Oracle database to give you a complete and integrated Business Intelligence solution.

1.2 What is a Discoverer workbook?

A Discoverer workbook is simply a named collection of worksheets. Each worksheet contains the data and graphs that you require to extract business information from the database. Each worksheet contains the result of a query.

Worksheets can show information:

You use Discoverer Portlet Provider to enable Discoverer worksheets to be accessed by Oracle Portal users.

1.3 What is a Discoverer Portlet?

Portlets are reusable information components that summarize or provide access to different types of information sources. You can customize the appearance of portlets on a per user or per group basis.

Discoverer portlet can be used to link a portal to an existing Discoverer worksheet. Discoverer provides two types of portlets:

  1. Discoverer PDK-Java portlets - These portlets are created based on Oracle Portal Developer Kit-Java (PDK-Java) and they can be published only in Oracle Portal and Oracle WebCenter Portal: Spaces.

  2. Discoverer WSRP portlets - These portlets are created based on the Java Portlet Specification (JSR 168) and the portlet provider is available as a WSRP (Web Services for Remote Portlets) application in the Discoverer installation. You can access this WSRP application using a WSDL URL. Discoverer WSRP portlets can be published in any portal that supports WSRP.

For more information about portlet styles available for Discoverer content, see "What are the different types of Discoverer portlet?".

1.4 What is Discoverer Portlet Provider?

Providers act as containers for portlets. Providers manage the portlets they own and handle the communication between the portlets and Oracle Portal.

Discoverer Portlet Provider is a Discoverer component that provides Discoverer portlets for publishing Discoverer content.

Discoverer Portlet Provider allows publishing Discoverer content in Oracle Portal, Oracle WebLogic Portal, and Oracle WebCenter Portal: Spaces.

You can also publish Discoverer portlets on third-party portals such as IBM WebSphere. For more information about registering a portlet producer and adding portlets in WebSphere, see the IBM WebSphere documentation.

Note:

WebSphere 6.0 does not support WSRP 2.0. When you register the Discoverer Portlet Provider with IBM WebSphere, use the registration URL for WSRP 1.0 as follows:

http://host:port/discoverer/portlets/wsrp1?WSDL

1.5.1 About the Discoverer Worksheet portlet

A Discoverer Worksheet portlet can contain a Discoverer worksheet and a graph.

The portlet publisher can include a link in the portlet (called Analyze) to enable users to open the worksheet in Discoverer Viewer for more detailed analysis (for example, drill, pivot).

In the figure below, the worksheet portlet called Video Tutorial Workbook - Crosstab Layout contains a Discoverer worksheet for analyzing profit figures for regions over time.

Figure 1-3 A Discoverer Worksheet portlet

Surrounding text describes Figure 1-3 .

For more information, see "How to add a Discoverer Worksheet portlet to an Oracle Portal page".

1.5.2 About the Discoverer Gauges portlet

A Discoverer Gauges portlet contains Discoverer worksheet data displayed as one or more semi-circular gauges. The gauges have a similar appearance to a speedometer. A gauge is a way of visualizing data within a range of values.

Discoverer Gauges portlets can only be created for crosstab worksheets.

It is possible to define low, acceptable, and high thresholds. The value ranges reflect key performance indicators (KPIs) for a business. Gauges are commonly used in dashboard applications.

The portlet publisher can include a link in the portlet (called Analyze) to enable users to open the worksheet in Discoverer Viewer for more detailed analysis (for example, drill, pivot).

The figure below shows a Discoverer Gauges portlet containing two gauges that display monthly profit sum values for East and Central regions.

For more information, see "How to add a Discoverer Gauges portlet to an Oracle Portal page".

1.5.3 About the Discoverer List of Worksheets portlet

A Discoverer List of Worksheets portlet contains links to Discoverer worksheets. When you click a link in a List of Worksheets portlet, you open the selected worksheet in Discoverer Viewer.

In the figure below, the Discoverer List of Worksheets portlet contains links to worksheets in the Video Tutorial Workbook (for example, Tabular Layout, Crosstab Layout).

Figure 1-5 A Discoverer List of Worksheets portlet

Surrounding text describes Figure 1-5 .

For more information, see "How to add a Discoverer List of Worksheets portlet to an Oracle Portal page".

1.6 What is Oracle Portal?

Oracle Portal is a component of Oracle Fusion Middleware that is used for the development, deployment, administration, and configuration of enterprise-class portals. Oracle Portal incorporates a portal-building framework with self-service publishing features that enable you to create, publish, and manage information within your portal. Your portal can publish information from your database and other sources, provide and gather information from internal and external customers, and manage the content they consume.

A portal is made up of groups of pages hosting many different types of content that come from many different sources, all presented from a single location, the portal. The basic structural components of a portal built with Oracle Portal include page groups, pages, tabs, regions, portlets, and items.

1.7 About Publishing Discoverer portlets in Oracle Portal pages

You can integrate Discoverer portlets in Oracle Portal pages using Discoverer Portlet Provider. Discoverer Portlet Provider is a Discoverer component that provides the Discoverer portlets for publishing Discoverer content in Portal pages.

If you have created a Discoverer worksheet in Discoverer Plus Relational, Discoverer Plus OLAP, or Discoverer Desktop, Oracle Portal makes it easy to publish the worksheet to a portal community.

For more information about portlet types available for Discoverer content, see "What are the different types of Discoverer portlet?".

The figure below shows a page in Oracle Portal containing Discoverer portlets.

There are several benefits that are available when you use Discoverer with Oracle Portal:

For more information about Oracle Portal, see Oracle Fusion Middleware Administrator's Guide for Oracle Portal.

1.8 What are the prerequisite tasks for publishing Discoverer portlets in Oracle Portal?

The prerequisite tasks for publishing Discoverer portlets in Oracle Portal are provided in the following list:

Note: For information about upgrading a 9.0.4 metadata repository to work with Discoverer Portlet Provider Version 10.12 or 11.1.1.1.0 and Oracle Portal 10.1.2 or 11.1.1.1.0, see Oracle Fusion Middleware Configuration Guide for Oracle Business Intelligence Discoverer.

1.9 Setting up Discoverer WSRP Portlet Preference Store for High Availability

The portlet preference store is used for persisting consumer registration handles and portlet preference data.

In a clustered environment, to make the Discoverer WSRP portlet preference store accessible to all Discoverer instances, you must set the value of the discoWsrpPrefStoreSharedPath variable to a shared path in the Discoverer application deployment plan. For more information, see the "Setting up Discoverer WSRP Portlet Producer in a Clustered Environment" section in Oracle Fusion Middleware High Availability Guide.

1.10 How to Publish Discoverer Portlets in Oracle Portal

To publish Discoverer portlets in Oracle Portal, do the following:

  1. (Optional) Ensure that Discoverer Portlet Provider is installed correctly.

    To verify a Discoverer PDK-Java Portlet Provider installation, enter the following URL in an Internet browser:

    http://<host.domain>:<port>/discoverer/portletprovider/

    If Discoverer Portlet Provider is installed correctly, you see the PDK-Java test page, displaying the message 'Congratulations! You have successfully reached your Provider's Test Page'. The test page also lists the Discoverer portlet types available.

    To verify a Discoverer WSRP Portlet Provider installation, enter the following URL in an Internet browser:

    http://host:port/discoverer/portlets/WSRPservice_version?WSDL

    For example: http://myserver:80/discoverer/portlets/wsrp2?WSDL

  2. Register Discoverer Portlet Provider with Oracle Portal. For more information, see How to register Discoverer Portlet Provider with Oracle Portal.

    This step only needs to be performed once (after installation). Typically, Oracle Fusion Middleware administrators register the Discoverer Portlet Provider.

  3. Use Oracle Portal to add Discoverer portlets to portal pages (for more information, see Chapter 3, "Authoring Oracle Portal Pages with Discoverer Portlets."

    Typically, a portal page designer would add Discoverer portlets to portal pages.

1.11 What are Discoverer connections?

A Discoverer connection is a stored set of database login details that comprises the following items:

Discoverer connections enable end users to start Discoverer without having to reenter database login details each time they start Discoverer. Discoverer connections and related information are stored in the DISCOVERER_PS schema.

If you have used Oracle's Single Sign-On functionality to establish a database connection, you are not prompted for password information when you start Discoverer

You must know about Discoverer connections because a connection must exist before you can publish Discoverer data in a Discoverer portlet (for more information, see Chapter 3, "Authoring Oracle Portal Pages with Discoverer Portlets").
