New Features 7

Introduction

8

Chapter 1: What’s New in IBM Cognos 8? IBM Cognos 8.4 consists of two major packages. One package includes IBM Cognos 8 BI PowerPlay and the other package includes all IBM Cognos 8 BI components except IBM Cognos PowerPlay. This new features guide is for the latter package. The new features in IBM Cognos 8.4 BI provide benefits to business managers and analysts, business modelers, report authors, and system administrators. All studios include a new feature for suppressing rows and columns that contain zero values, missing values, or overflow values. A new lineage feature in Report Studio, Query Studio, Analysis Studio, and the report viewer, allows you to view life cycle information on each piece of data.

Business Managers and Analysts In Query Studio, the addition of more user preferences and the enhancement of filtering and sorting options make it quicker for Business Analysts to set up and run reports. Also, because modelers can set default filters in a Framework Manager model, it is easier for users to set up and run reports. Analysis Studio includes a new feature that makes it easier to apply suppression across multiple items. From within Analysis Studio, you can also display the date on which a cube was last updated.

Business Modelers Business modelers using Transformer can now use fact data from SAP BW OLAP data sources. This means they can create Transformer models based on existing dimensional models. Transformer also supports Excel spreadsheets as data sources.

Report Authors Report authors now have more drill-through capabilities, including the ability to pass filters from the source report to the target report. They can also conditionally style crosstab cells based on values in other cells. More types of charts and more graphics are included with Report Studio for use in reports and dashboards.

Report Consumers You can add additional information to a report by using comments. This information can include questions or explanations. Comments may include the original commentator’s ID and the time the comments were added. For more information see the Administration and Security Guide.

System Administrators Support for IBM Cognos 8 is extended to include more operating systems, data sources, browsers, application servers, and portals. For more information see Appendix A: "Supported Environments" (p. 23).

New Features 9

Chapter 1: What’s New in IBM Cognos 8? It is now easier for Administrators to organize packages and control which packages specific users can see in the portal.

10

Chapter 2: Targeting Information IBM Cognos 8 Business Intelligence provides features that help you to efficiently target information to different types of users.

More User Preferences in Query Studio You can now save more user preferences in Query Studio. New preferences include the following: ●

You can choose a data retrieval mode that allows you to run a report with all data, preview it with limited data, or preview it with no data



You can specify a default template for reports



You can select the type of filter dialog to use by default. Types include picklist, type-in, or select with search.

Prompt Types for Levels in Query Studio Can be Defined in Framework Manager Query Studio provides a metadata tree that is level based. You can easily create a report based on levels by dragging levels from the metadata tree to a report list or crosstab report. For a dimensionally-modeled relational data source you can now specify in the model the default type of the filter dialog that is supplied to the user.

Extended Support for Dimensionally-modeled Relational Data Sources There is now support for multiple hierarchies of a single dimension for dimensionally-modeled relational data sources. In addition, the sorting of data by member is enhanced. A member can appear sorted in the metadata tree and on the report without slowing performance. Also, members of a level are sorted in the context of their ancestor levels. This means that the hierarchical relationship of a level is considered when member sorting is applied.

Dimension Management You can now maintain business viewpoints and collaborate to organize information for performance management. This gives you complete control over your domains, reduces errors, provides transparency and consistency to changes, and allows collaboration with a single source of dimensions and hierarchies across performance management..

New Features 11

Chapter 2: Targeting Information

12

Chapter 3: Extended Reporting and Analysis IBM Cognos 8 Business Intelligence provides enhancements for report authors working with Report Studio or Query Studio, and business analysts working with Analysis Studio.

Access to the IBM® WebSphere® Business Glossary If you use the IBM WebSphere Business Glossary, you can now access the glossary from any of the following data objects in Report Studio, Query Studio, and Analysis Studio: ●

Query subject



Query item



Measure



Dimension



Hierarchy



Level



Property/attribute



Top node member



Member



Level item

Extended Suppression Capabilities in all Studios You can now suppress rows, columns, or rows and columns based on the following: ●

zero values



divide by zero values



missing values



overflow values

This can be done on any suppression-enabled package such as relational, dimensionally-modeled relational, and OLAP data sources. Suppression can be enabled at the discretion of the Transformer or Framework Manager modeler during publishing.

Lineage It is now easier to view information on the life cycle of a data element and see the major transformations that occurred as it traveled through a system. For technical users, this may include in-depth New Features 13

Chapter 3: Extended Reporting and Analysis information about the data sources, data types, calculation expressions, and details of ETL transformations. For business users, the information may be as simple as the point of origin of the data and when it was last updated. You can launch Lineage from Report Studio, Query Studio, Analysis Studio, and the report viewer.

New Features for Report Authors New features in Report Studio and Query Studio provide advantages for report authors.

Dashboards A new dashboarding product lets you create and consume interactive dashboards. You can also combine dashboards with third-party information sources, such as RSS feeds, to create enhanced performance management dashboards. It is now easier to create personalized reports with a standardized appearance.

Improved Scorecarding New scorecard portlets let you share scorecarding information to a wider business community by eliminating the need to go into the IBM Cognos 8 BI scorecarding interface to view strategy maps and impact diagrams. Comments can now be added to strategic objectives showing date and owner, for improved collaboration in defining and editing strategic objectives.

Crosstab Measures in Report Studio can be Formatted Based on a Another Crosstab Measure You can now apply conditional styles to crosstab cells based on an adjacent value in the crosstab. For example, you can conditionally color the bubbles in a bubble chart based on any combination of the measures, and you can conditionally color an entire row of the crosstab based on any measure in the columns.

Drill Up and Down can be Synchronized for Multiple Queries in Report Studio Reports You can now link groups of data items from different queries in a report so that when you drill up or down on one query, data items in the other query also drill up or down.

The dataItem Element in Report Studio Supports Calculated Members and Measures The dataItem element is now extended to support calculated members and measures. This allows sorting by calculated members.

14

Chapter 3: Extended Reporting and Analysis

Shared List Queries in Report Studio Report Studio now provides an option to share the database query between two list frames that have the same logical query. This improves performance by minimizing the number of queries executed against the database.

Generated Background Images The Report Studio author can now define background images for objects, such as charts, to enhance the presentation quality of a report. The new capabilities include borders with rounded corners, transparent background fills and images, drop shadows, and background gradients.

New Charts in Report Studio The following new chart types are available in Report Studio: ●

microcharts These miniature charts are useful for improving the visualization of data in crosstabs, lists, and dashboards. They are smaller versions of column charts, bar charts, and line charts. Column microcharts and bar microcharts are also available in stacked and 100 percent stacked configurations. Another type of microchart is a win-loss chart in which the value of each column is either 1 or -1, often denoting a win or loss.



Marimekko charts A Marimekko chart is a 100 percent stacked chart in which the width of a column is proportional to the total of the column's values.

Line charts now include an option for creating step line charts. Step line charts are similar to line charts but use vertical and horizontal lines to connect the data points, forming a step-like progression.

RootMember Function in Report Studio A new function, rootMember, returns the root member of a single-root hierarchy.

Excel Color Palettes There is now an easy way to match the palette of Report Studio charts with charts from Excel. The Palette dialog box provides new palettes that match those from various versions of Excel.

More Report Graphics Additional colorful graphics are now available for dashboards and reports.

Enhanced Sorting and Filtering in Query Studio In Query Studio, you can now filter without adding a column. A context menu in the metadata tree allows you to add filters directly from the tree without first having to add the metadata item to the report. Text filters now include multi-line text control. You can paste text from other applications into type-in filters. You can also use wildcards to define filters. New Features 15

Chapter 3: Extended Reporting and Analysis

Prompted Reports Now Supported in Go! Mobile Increase the usability of your mobile devices by running prompted reports in IBM Cognos Go! Mobile. IBM Cognos Go! Mobile supports most standard prompts.

Scheduling for Go! Mobile You can now schedule report delivery to mobile devices.

New Features for Business Analysts Analysis Studio provides new features for the business analysts.

Persistent Column Widths in Analysis Studio In earlier versions, the column width set in a report was not saved. Now you no longer have to spend extra time resizing columns to improve the visual aspects and general usability of the report when you reopen it.

Multiple Intersections (Tuples) can be Selected for Suppression in Analysis Studio It is now easy to add or remove sparsity tuples. Previously, you had to invoke suppression on each measure multiple times for each nested group to ensure that only rows with zero or null values were suppressed. You can now invoke suppression across multiple items at the same time and verify against a list of items to show how suppression was applied. Note: Reports that have been created using the totals-based suppression method in IBM Cognos 8 Version 8.1 will be upgraded to use the 8.4 suppression method. Reports that have been created using the context-sensitive suppression in IBM Cognos 8 Version 8.2 will not be upgraded because the context-sensitive suppression method can be used in conjunction with the 8.4 suppression method.

The Update Date for a Cube can be Displayed In Analysis Studio you can now display the date on which a cube was last updated.

16

Chapter 4: Enhanced Deployment and Administration The new IBM Cognos 8 Business Intelligence release provides new functionality to support enterpriseclass BI deployments.

64-Bit and 32-Bit Application Servers Now Supported IBM Cognos 8 BI now provides the ability to use the latest popular application servers, such as 64bit SAP NetWeaver and others, giving you greater compatibility and the potential for increased scalability. At the same time, we offer the flexibility of continuing to use your 32-bit application servers. For more information, see the Installation and Configuration Guide.

Enhanced Drill-through Capabilities In earlier versions of IBM Cognos 8, model-based drill-through supported only reports created in Analysis Studio, Query Studio, or Report Studio as targets. Other types of drill-through targets are now supported. For example, you can drill through to PowerPlay Studio reports saved in the content store, or to a PowerCube. There is now dynamic filtering of data in Report Studio reports. You can automatically apply filter data from a report to a drill-through target from that report. When you drill through from a Report Studio report to a target report, if what you have selected is in a query in the target report, the results are automatically filtered. A Report Studio author can now define a drill definition that allows a report to be shown on the Go To page only when a specific measure, dimension, hierarchy, alternate hierarchy, level, or query item exists in the source report. This allows the author to restrict when the drill path is available to users. IBM Cognos 8 provides improved selection for drill through parameters. If the source is based on a dimensional package, you can choose what property of the source metadata item to map to the target. For example, you can map the member caption of the source metadata item to a relational value in the target instead of using the business key. For more information, see the Administration and Security Guide.

Additional User Capabilities and Easier Organization for Packages You can specify user capabilities for individual packages. Also, there is more flexibility when organizing packages in the content store.

New Features 17

Chapter 4: Enhanced Deployment and Administration

Extended Support for Single Signon IBM Cognos 8 now provides for single signon through LDAP namespace authentication for an Essbase OLAP data source. In addition, single signon support is added for Teradata and DB2. For more information, see the Administration and Security Guide.

Objects Can be Hidden in the Portal Multiple packages in the root folder can be hidden from the UI. Administrators can control whether users can choose a preference to view hidden objects.

Namespaces Can be Hidden in the Login Page Administrators can now register trusted signon namespaces without having them shown on the namespace selection list that appears at logon. This is useful if you want to integrate single signon across your system while maintaining the ability for customers to authenticate directly to IBM Cognos 8 without being prompted to choose a namespace.

Improved Performance for Reports that Require Prompt Values You can specify that prompt values for a report are stored in a cache. This enables the report server to render a prompt page without having to run a prompt query and access the database for each report. The first time that a report is open, the cache is created. Then, for each user who subsequently opens the report, the cache is used. This results in performance improvements for reports that have prompt pages.

Enhancements to Data Manager The bulk loader support in Data Manager is extended to support Netezza, Sybase, SybaseIQ, and TM1. A new JobStream node has been added that allows you to execute IBM DataStage jobs within aJobStream. You no longer need a license key to control the use of the Designer UI. The SQLTXT Designer UI in Data Manager is extended to provide a quick method for duplicating a table definition. For more information, see the Data Manager User Guide.

New Data Sources For more information about new data sources, see the Administration and Security Guide.

IBM Cognos TM1 The IBM CognosTM1 data source supports named levels.

18

Chapter 4: Enhanced Deployment and Administration You can also test IBM Cognos TM1 data source connections to IBM Cognos TM1 namespacesecured cubes from IBM Cognos Administration. For more information, see the Administration and Security Guide.

IBM Cognos Now! Both IBM Cognos Now! cubes and view objects are supported as data sources. Note: For information about constraints when using Cognos Now! views, see the IBM Cognos Now! Workbench Technical Reference.

IBM InfoSphere Warehouse Cubing Services IBM InfoSphere Warehouse Cubing Services provides a multidimensional view of data stored in a relational database Now you can now access IBM InfoSphere Warehouse Cubing Services with IBM Cognos 8 BI just as you would any other data source.

Composite Information Server is Replaced By IBM Cognos 8 Virtual View Manager Composite Information Server was available with earlier releases of IBM Cognos 8. In the current release, Composite Information Server is replaced by IBM Cognos 8 Virtual View Manager, which is an IBM proprietary product that is based on a new version of Composite Information Server. For more information, see the Administration and Security Guide and the Architecture and Deployment Guide.

Diagnostic Tools Added to IBM Cognos 8 BI 8.4 Diagnostic tools are available with IBM Cognos 8.4 to help identify and troubleshoot issues by providing you with a way to automate the collection of detailed systems information. Diagnostic results can be attached to cases logged with IBM Cognos Support, which significantly reduces the time spent on collection of environment and product information. These diagnostics are read-only and do not make any changes to the environment of IBM Cognos products.

IPv6 Compliance Internet Protocol version 6 (IPv6) is designated as the successor of IPv4, the current version for general use on the Internet. The much larger address space in IPv6 allows greater flexibility in assigning addresses. For more information, see the Installation and Configuration Guide.

New Features 19

Chapter 4: Enhanced Deployment and Administration

Open IBM Cognos PowerPlay Series 7 Reports in Other Studios In both IBM Cognos Connection and PowerPlay Studio, you have additional actions available when the migration service has been installed. You can choose to open a PowerPlay Studio or IBM Cognos PowerPlay Series 7 report with Analysis Studio or Report Studio.

New Columns Added to COGIPF_MIGRATION Table The audit database contains a table, COGIPF_MIGRATION, that is used to log information about migration activities. Four additional columns, MSGNUM, SOURCE_TYPE, SOURCE_PATH, and SOURCE_NAME, have been added to this table for this release. Customers who have created a COGIPF_MIGRATION table with an earlier version must upgrade their table to include the additional columns.

PowerPlay IPF Database Audit Logging A new option is provided for IBM Cognos PowerPlay 7 customers who have migrated to PowerPlay 8 in IBM Cognos 8.4. You can now get audit information using either the Series 7-style PowerPlay audit database, or through IPF logs in cogserver.log. This lets you get audit information in an IBM Cognos 8 IPF database.

PowerPlay Service Requests Now Show in Current Activities Now you can see interactive requests being executed by the PowerPlay service in Current Activities in Cognos Administration. You can also cancel these requests.

IBM Cognos Transformer 8 Automation The initial release of IBM Cognos Transformer 8 contained no programmatic automation support. You had to script using MDL, the Transformer Model Definition language. Now, IBM Cognos Transformer re-instates OLE automation with updated Active X controls to allow .Net support and new C8.3 functionality for the 8.4 release and also adds support for new IBM Cognos Transformer 8 features and functionality, including security. If you are an IBM Cognos Series 7 customer who is currently using IBM Cognos PowerPlay Transformer OLE automation, you will need to upgrade your code to leverage the new IBM Cognos 8 OLE functionality.

Improved Lineage Now you can access lineage for model filters from the metadata tree in the Report Studio, Query Studio, and Analysis Studio. Technical users can also include information about filters in report and model lineage.

20

Chapter 4: Enhanced Deployment and Administration

Six New Languages Added Besides English and three other languages (French, German, and Japanese), IBM Cognos 8 BI is now localized into the following additional languages: simplified Chinese, traditional Chinese, Korean, Italian, Spanish, and Brazilian Portuguese. For more information, see the Installation and Configuration Guide.

J2EE Security Support The IBM Cognos 8 BI Server application and the Servlet Gateway application can run on a WebSphere 6.1 32-bit and 64-bit platform with Java 2 security enabled, restricting access to local resources.

Cell Context Data and Drill-Through Information Included in Chart Data Executive Dashboards now have cell context and drill-though information included when the data is inserted into a chart object, as is available in rendered lists and crosstabs.

UNIX Installation Text User Interface Removed For UNIX Installation, the Newt library and its dependent text user interface (issetupcc) has been removed. UNIX users with X-server running will continue using the motif-based user interface "issetup" to launch the product installation. UNIX users without X-server will launch unattended installs by invoking the "issetup" command line parameter "-s {filename}" to perform necessary installation tasks. You may need to modify the response file to accept the license agreement if a non-default custom install is required.

Parameterized SQL Governor The generated Cognos SQL can either use parameter markers (also known as sql99 host variables) or literal values. The SQL governor provides a way optimize RDBMS performance. For example, setting the governor to use literal values allows RQP (Relational Query Planner) to rewrite the parameters to literal values before sending the query to UDA for non-detail query cases. The governor can be set in the model, which can then be overridden on a per-query basis. If the governor is neither set in the model nor in the query, then the setting is derived from the server configuration file.

New Features 21

Chapter 4: Enhanced Deployment and Administration

Framework Manager SQL xmin( ) Model Governors Cognos strongly endorses the use of materialized views for optimum performance. However, the default generation of SQL xmin( ) functions for attributes disables the use of materialized views and can result in problems. Two configuration flags exist already to stop the xmin( ) generation in the case of determinants and levels. You can now use two configuration options in Framework Manager as model governors to drive the xmin( ) generation for both levels and determinants. If the governor is missing, RQP (Relational Query Planner) will read the value of the corresponding CQE configuration flag from their configuration file and use it instead.

New Query Hint to Populate SAPBW Member Cache This query hint signals the SAP provider that the query associated with the hint is for the cache server. If this query hint is set to true, the dimensions are passed down to the SAP cache server, encrypted, and saved for later use. Query hint name: QUERY_HINTS_CACHESERVERQUERY Query hint description: Query for Cache Server Default value: false This new query hint has 3 states: true, false, and undefined. When undefined, the program falls back to default behavior, which is the false state.

Generated Native SQL Contains Comments SQL comments can help you understand which tables are being accessed by which users and is useful for debugging and auditing, as well for better managing resource utilization and performance.

Composite Source Code Composite source code is now IBM Cognos property.

Automatic Detection of Compatibility Mode in DB2 zOS A DB2 zOS subsystem may be configured to run in compatibility mode. Previously,while in compatibility mode the subsystem would not accept DML/DDL constructs that are part of the release because the constructs are not accessible until the system is moved to new feature mode. IBM Cognos 8 now adjusts to new feature mode if necessary.

Connection Command Blocks Exposed for Teradata Connection command blocks for Teradata connections are now exposed in the portal, along with the currently exposed DB2, SQL Server, and ORACLE connections.
