Why Move to the Web?

Developing and deploying reports applications on the Web can benefit your enterprise by: Reducing costs Improving productivity Increasing availability Maintaining product support Publishing any data in any format to any

destination Leveraging a standards-based architecture Utilizing new features

Why Move to the Web?Reporting is the delivery of information to information consumers. These consumers must often further investigate that information. Historically, different tools performed different tasks. However, there was a growing need to integrate data consolidation, data analysis, and enterprise reporting tools to provide a seamless environment that allowed users to move from the role of information consumer to information investigator. The combination of providing information and enabling additional investigation of that information is referred to as business intelligence (BI). In an increasingly competitive world, enterprises are constantly in need of BI that empowers the decision makers in an organization to act on the information and thus impart that extra competitive edge to the organizations products and services. Oracles BI solution provides users with the capability to easily integrate diverse data sources, convert this data into information, share this information with authorized users, and exploit the information to learn more about the business and its customers. Oracle Reports is the enterprise reporting component of Oracles BI offering.

Why Move to the Web? (continued)Enterprise reporting grew out of a business need for better, faster, and more flexible delivery of individually tailored information to a very large number of users. No environment is better suited to fulfill this need than the Internet. Through Web reporting, companies can provide critical information to a large and geographically distributed user base in a timely manner. By moving your client/server report applications to the Web, your organization benefits by:

Reducing costs Improving productivity Increasing accessibility Maintaining product support Publishing any data in any format to any destination Leveraging a standards-based architecture Utilizing new features

This lesson provides you with a closer look at these benefits.

Reducing Costs

Multiple products and vendors

Multiple PCs

Integrated product set

Centrally managed server

Reducing CostsOracle Reports applications are deployed on the Web with Oracle Application Server 10g: a single, integrated product that is designed to lower the total cost of ownership associated with developing, deploying, and managing applications. With Web deployment, you eliminate the costs associated with maintaining software on all the clients. You have to manage only the server.

Improving Productivity

Improving ProductivityThe key to reducing development time is to take the element of intensive effort out of report development. Oracle Reports does not require that you write numerous lines of code or manually format complex layout structures. As a developer, you will continue to use the wizard-driven application development environment of Reports Builder, even for Web reports. Oracle Reports 10g takes advantage of JavaServer Pages (JSP) technology to deliver high-quality HTML pages for Web publishing. JSP technology separates the dynamic portion of your Web page from the static HTML. This enables Web page designers in your organization to create the visually appealing, static portion of the page by using their favorite Web-authoring tool. Page designers who have limited or no Java programming experience can modify the appearance of the JSP page without affecting the generation of its content. You, as the application developer, need to focus only on adding the dynamic data component to the page.You can develop a report once and deploy it to multiple destinations. You can select various output formats, including HTML, Hypertext Markup Language with a Cascading Style Sheet (HTMLCSS), Extensible Markup Language (XML), PDF, Postscript, and rich text format (RTF). You can share a single data model among all output formats. In addition, you can customize the appearance and content of your output at run time by applying XML customization files.

Increasing Availability

Officeworkers

Telecommuters

Suppliers

Customers

Increasing AvailabilityAs soon as a new report application is deployed on the Web, it is instantly available to users who log in to the application. You can easily modify a Web-deployed application without affecting the accessibility to customers and vendors. For example, you can modify an order listing so that customers can view the status of their orders online. Because you need not install the modified application on every client, it is instantly accessible over the Web.With a Web application that is accessible anywhere, you can reach customers that you could never reach before, and you can enable internal users to connect to applications from home with only a browser. Using the capabilities of Oracle Application Server 10g, you can also make your report accessible through a Web portal or on a cell phone.

Maintaining Support

Maintaining SupportOracle Reports has maintained its position as a premier enterprise-reporting tool by keeping pace with rapid shifts in technology. As rapidly as technology has shifted, Oracle Reports has moved from character-based, to graphical-based, to client/server, and now to multitier Web-based development and deployment. Oracle Reports 6i was the last version of Oracle Reports to support both a character-mode and a client/server GUI reports viewer. With Oracle9i Reports, users moved to a Java 2 Enterprise Edition (J2EE) Web-based multitier environment. Oracle Reports 10g (9.0.4) and Oracle Reports 10g Release 2 (10.1.2) have improved the performance and scalability of reports applications in the Web-based environment and have also provided a host of new features.If you continue to use client/server deployment, you must continue developing report applications using Oracle Reports 6i, whose support term is limited. It is recommended that you upgrade to Oracle Reports 10g Release 2, a component of Oracle Developer Suite 10g. This will assure you continued technical assistance, bug resolution, and access to updated patches. Visit Metalink (http://metalink.oracle.com) for the latest information on the desupport dates for Oracle6i Reports and Oracle9i Reports.

Publishing Enterprise Data

Publish from any source, in any format, to any destination with high fidelity.

TEXT

OLAP

JDBC

XML

Publishing Enterprise DataIn a modern IT environment, data is produced in different places and in different formats. For example, in a manufacturing organization, each geographically distributed warehouse may store inventory data in a relational database, whereas the headquarters of the organization may prefer to store basic data, such as the average inventory per warehouse, in XML format. You must collect data from these different sources and present it as consolidated information.Oracle Reports enables you to publish data from any source in any format with high fidelity.It supports SQL, PL/SQL (ref-cursor), XML, JDBC, Oracle OLAP, and text files (both delimited and fixed format). You can combine queries from different data sources in a single report and link them to produce master-detail relationships. In addition, you can use Java-based APIs to create access mechanisms for data common to your business and integrate them into Oracle Reports, enabling you to use this data directly in your report. Oracle Reports gives you flexibility in the presentation of your data. You can create high-fidelity paper-oriented reports suitable for printing, as well as create true Web reports in which the data is part of a Web page that is designed for your corporate Web site. You can publish your data to any destination, including a browser, file, e-mail, printer, OracleAS Portal, FTP server, and Web-based Distributed Authoring and Versioning (WebDAV).

Leveraging a Standards-Based ArchitectureUtilizing a Standards-Based, Modular ArchitectureOracle Reports uses an open, standards-based, modular architecture.

Oracle Reports uses a reporting paradigm of a JavaServer Pages (JSP)based Web source, which enables you to address all the needs of dynamic Web publishing. Based on the industry-standard JSP 1.2 technology, it allows you to inject dynamic report content into any surrounding structure. Using custom JSP tags, you can add programmatic elements in existing Web pages.

Servlets are Java programs that run as part of a network service, such as a Web server, and respond to requests from clients. Servlets extend the functionality of a Web server by delivering dynamic content.

Java 2 Platform, Enterprise Edition (J2EE) is a specification that defines the standard for developing component-based multitier enterprise applications for the Web. The J2EE platform provides many features, such as write once, run anywhere portability, JDBC APIs for database access, CORBA technology for interaction with existing enterprise resources, and a security model that protects data even in Internet applications. In addition, it provides full support for Enterprise JavaBeans (EJB) components, Java Servlets API, JavaServer Pages, and XML technology.

Leveraging a Standards-Based Architecture (continued)Utilizing a Standards-Based, Modular Architecture (continued)

Common Object Request Broker Architecture (CORBA) is an industry-standard specification for application interoperability defined by the Object Management Group (OMG). In a distributed computing network using the CORBA architecture, heterogeneous systems can communicate with one another independent of platform, operating system, programming language, network, and protocol. The Reports Server is implemented as a CORBA object; clients, such as rwservlet and rwclient, communicate with the server through CORBA calls.

Internet Inter-ORB Protocol (IIOP) is an industry-standard protocol developed by OMG to implement CORBA solutions over the Web. IIOP enables browsers and servers to exchange integers, arrays, and more complex objects, unlike HTTP, which supports only transmission of text.

The Oracle Reports Java APIs help you to define your own plug-ins for data sources, output destinations, security infrastructure, cache management, engines, and so on.

The OracleAS Reports Services Event-Driven Publishing API is a PL/SQL package that enables you to run a report based on the occurrence of an event in the database.

Oracle Reports provides extensive support for Extensible Markup Language (XML). You can specify customizations to reports with an XML file, use XML as a data source, describe an entire report definition in XML, and deliver output in XML format.

Objectives

After completing this lesson, you should be able to do the following: Describe the difference between deprecated and

obsolete functionality Describe the migration path for Reports

applications that were developed with previous releases of Oracle Reports

Identify enhancements in the Reports Builder user interface

Migrate a Reports application by replacing deprecated and obsolete functionality

OverviewSuccessful businesses know that presenting data in a timely and meaningful way provides a powerful advantage over the competition. To that end, businesses continue to need ever more powerful tools for producing high-quality reports from the mass of disparate data sources kept in every major corporation today. Oracle Reports has maintained its position as a premier enterprise reporting tool by keeping pace with rapid shifts in technology. As technology has shifted, Oracle Reports has moved from character-based, to graphical-based, to client/server, and now to multitier Web-based development and deployment. In this lesson, you learn about the features that are deprecated, obsolete, or changed in Oracle Reports 10g. You also learn how to migrate existing reports that use some of these features.

Deprecated and Obsolete Functionality

Deprecated functionality is no longer documented and its use is discouraged.

Obsolete functionality has been removed from Oracle Reports and replaced with new technology.

Deprecated and Obsolete FunctionalityWith any product, the usefulness of its technology begins to diminish over time.Deprecated functionality is at a point where product advances and enhancements have caused the functionality to be incorporated using another approach, or its general usefulness has been superseded by other precedents. As a result, that functionality is no longer documented and its use is discouraged, because it will be made obsolete in a subsequent release of Oracle Reports. The deprecation phase is provided so that customers can gradually migrate to new functionality before the deprecated functionality is made obsolete. Obsolete functionality is no longer available in Oracle Reports 10g Release 2 (10.1.2). By continuing to remove obsolete functionality and replacing it with new technology, Oracle Reports developers ensure that customers always have the latest functionality they need for successful e-business development and deployment. Note: For details about deprecated, obsolete, and changed functionality, refer to the document Oracle Reports 10g: Statement of Direction on the Oracle Technology Network (http://www.oracle.com/technology/products/reports/10g/SOD_Reports.html).

Deprecated and Obsolete Functionality (continued)Functionality that is deprecated in Oracle Reports 10g Release 2 (10.1.2), or deprecated in earlier releases (Oracle9i Reports or Oracle Reports 10g (9.0.4)), includes:

Executables Environment variables SRW.SET_ATTR built-in function SRW built-in parameters related to formatting SRW built-in procedures and parameters related to tracing Embedding an OLE2 object Oracle Express data source and related options Reports Server clustering Import Portal component User exits

Functionality that is obsolete in Oracle Reports10g Release 2 (10.1.2), or made obsolete in earlier releases (Oracle9i Reports or Oracle Reports 10g (9.0.4)), includes:

Character mode run-time viewer Graphical user interface for reports run time Oracle Graphics Executables applicable to client/server environments Command line keywords System parameters Oracle Forms built-in RUN_PRODUCT for submitting report requests Running the Reports Server as a Windows service Creating buttons in the layout model Defining external queries PVCS and Clearcase for source control Storing report definitions in the database Oracle Reports Call Interface MAPI email protocol Web Wizard

Changed Functionality and NamingOracle Reports has improvements in functionality with every new release. In keeping with new and enhanced functionality, it was necessary to change the names of some of the properties, executables, and interfaces. For example, because the parameter form is applicable only to the paper layout, and not to the Web layout, the previously named Parameter Form view in Reports Builder is now called Paper Parameter Form view. Functionality changes include:

Behavior of the command line keyword BACKGROUND Behavior of the command line keyword BATCH

Naming changes include: Executable names Environment variable names Reports Builder user interface names

Migrating Reports Applications

1. Open your .rdf in Reports Builder 10g.2. Replace deprecated and obsolete functionality.3. Recompile any PL/SQL.4. Save your report definition.

6i 10g

Migrating Reports ApplicationsThe report applications you created with Oracle Reports 6i have the extension .rdf (report definition file). These report definitions include one layouta paper layout. You should be able to run your existing .rdf files with Oracle Reports 10g with no modifications, except for replacing obsolete functionality. You may need to open the report definitions in Reports Builder 10g, recompile any PL/SQL, and save the report.

Reports Builder User Interface Changes

Report Editor views: Data Model Web Source Paper Layout Paper Design Paper Parameter Form

Other UI changes: Previewer Property Inspector

Reports Builder User Interface ChangesWhen you open your old report definitions in Reports Builder, you will notice changes in the user interface. As you know, every report module defines two key components in a report: the data and the layout. Beginning with Oracle9i Reports, each report module can have a data model, a paper layout, and a Web layout. The data model, as well as program units, can be shared by the paper and Web layouts. The Object Navigator includes a Web Source node for every report module. The Report Editor has been enhanced to include a Web Source view. The Web Source view displays the HTML and JSP source for a report. The other Report Editor views are Data Model, Paper Layout (previously called Layout Model), Paper Design (previously called Live Previewer), and Paper Parameter Form (previously called Parameter Form). The Object Navigator also reflects the name changes.The Runtime Previewer has been renamed Previewer. To display the printed version of a reporton your screen, access the Previewer by selecting File > Print Preview from the menu. The Property Palette has been renamed Property Inspector.

Formatting with the SRW Built-in Package

To visually format fields in your report, use the new attribute-specific built-ins, such as: srw.set_background_fill_color srw.set_font_face srw.set_fill_pattern srw.set_text_color srw.set_border_width

March 7th

Formatting with the SRW Built-in PackageThe SRW.SET_ATTR built-in function was originally designed to save time and resources by allowing you to set attributes such as font face, foreground and background colors, border width, and so on using a single built-in function. However, each of these attributes has evolved into a separate built-in function (for example, SRW.SET_FONT_FACE and SRW.SET_BORDER_WIDTH). Note: To replace deprecated SRW.SET_ATTR functionality and attributes with new SRW built-in procedures in the PL/SQL code in your report, refer to the Deprecated SRW.SET_ATTR functionality table in the document Oracle Reports 10g: Statement of Direction on the Oracle Technology Network (http://www.oracle.com/technology/products/reports/10g/SOD_Reports.html).

Formatting with the SRW Built-in Package (continued)Example: You want to display salaries greater than $2,000 with specific visual characteristics, such as font style, size, weight, and so on. In your 6i report, you coded a format trigger, built an attribute mask, and applied that mask to the salary field if the value in the field was greater than 2,000. Your code looked something like this:

if :salary > 2000 thensrw.attr.mask := srw.face_attr +

srw.sz_attr +srw.weight_attr +srw.style_attr +srw.gcolor_attr;

srw.attr.face := times;srw.attr.sz := 18;srw.attr.weight := srw.bold_weight;srw.attr.style := srw.underline_style;srw.attr.gcolor := blue;srw.set_attr (0, srw.attr);

end if;return(TRUE);

To modify this report for 10g, edit your format trigger and use the new built-in functions as follows:

if :salary > 2000 thensrw.set_font_face(times);srw.set_font_size(18);srw.set_font_weight(srw.bold_weight);srw.set_font_style(srw.underline_style);srw.set_text_color(blue);

end if; return(TRUE);

Replacing OLE2 Objects

Replacing OLE2 ObjectsOracle6i Reports supported the use of OLE2 (Object Linking and Embedding). In the Builder, you were able to create an OLE2 container and define its contents, such as a spreadsheet, graphics, video, or sound. This functionality is applicable only to client/server environments. To migrate a report containing an embedded OLE2 object, you must delete the OLE2 object from the report definition. There is no direct replacement in Oracle Reports 10g because this functionality is not applicable to Web environments. However, you can mimic this functionality by using one of two options:

Display images and text from external files by using the File Link tool in the Paper Layout. If you have access to a Java plug-in that can read and embed an object (for example, a

Microsoft Word document or Microsoft Excel file), you can use the plug-in inside Oracle Reports via the Java Importer utility. O

Migrating Charts

Oracle6i Reports

Oracle Reports 10g

Migrating ChartsTo add charts to your reports in Oracle6i Reports, you used Oracle Graphics. Oracle Graphics, or Graphics Builder, is no longer supported. Since release 9i, Oracle Reports uses Business Intelligence Beans (BI Beans) to create and display graphs in reports. There is no direct migration path from Oracle Graphics to the BI Beans graphing functionality. There is no separate graphics tool; all of the graphing options and controls are now available in Reports Builder through the Graph Wizard. You must re-create all of your graphs by using the new Graph Wizard in Oracle Reports Builder 10g. The wizard produces a graph definition that consists of XML information and a JSP tag to enable you to add graphics to Web reports. Using the Graph Wizard, you can generate more complex graphs with a larger variety of graph typesover 50, including three-dimensional (3-D) graphs. You learn more about the Graph Wizard in the lesson titled Using New Features in Oracle Reports: Development.Note: Reports built with previous versions of Oracle Reports containing Oracle6i Graphics charts will continue to run when the report is opened in Oracle Reports 10g Release 2 (10.1.2) if the Oracle6i Graphics Runtime is installed on the same machine in a separate ORACLE_HOME. However, this is not a supported configuration, and Oracle will not fix bugs that result from this configuration.

Replacing Buttons

Replacing Buttons Buttons were used in a client/server environment to enable users to interact with a report in the Previewer at run time. You created buttons to:

Access a URL Drill down to a separate detail report Display multimedia information related to report items

Because Oracle Reports no longer has a GUI viewer, button functionality is not supported. If you open an existing 6i report that contains buttons, the buttons are displayed as simple text objects. In 10g, use URLs, links, and parameters to drill down to detailed reports and access multimedia objects such as sound and video. Hint: If you want to preserve the look of a button in your migrated reports, include an image as the object with the associated link. O

Referencing System Parameters

Referencing System ParametersReports Builder provides system parameters that you use to modify standard run-time settings for each report definition. Each parameter has a default value that you can modify.In Oracle Reports 10g, there are seven system parameters: COPIES, DESFORMAT, DESNAME, DESTYPE, MODE, ORIENTATION, and PRINTJOB. The system parameters BACKGROUND, CURRENCY, DECIMAL, and THOUSANDS are obsolete. Instead, use the new methods of configuration such as setting the appropriate environment variable or using command line keywords.

Replacing User Exits

ORA_JAVA built-in package Java Importer ORA_FFI built-in package

Replacing User ExitsIn earlier releases of Oracle Reports, user exits provided a way in which to pass control (and possibly arguments) from Oracle Reports to another Oracle product or 3GL, and then return control (and possibly arguments) back to Oracle Reports. With Oracle Reports 10g, you can call Java methods by using the ORA_JAVA built-in package and the Java Importer. This reduces the need to have user exits in a report and allows for a more open and portable deployment. You can also use the ORA_FFI built-in package, which provides a foreign function interface for invoking C functions in a dynamic library.

The ORA_JAVA built-in package provides an interface for invoking Java classes from PL/SQL.

The Java Importer enables you to access the rich environment of the Java programming language from your reports. Using the Java Importer, you can automatically generate PL/SQL packages and procedures to access Java classes, and then program with the generated PL/SQL in your reports. The PL/SQL generated by the Java Importer is robust, offering support for the original Java class constructors, methods, and fields. Beyond simply mapping static methods to PL/SQL functions and procedures, the Java Importer provides support for persistent Java objects, with support for type mapping and array objects.
