4 Rational Insight and Rational Asset Manager IBM Rational Insight provides a single point of access for consistent and objective insight into development projects. Rational Insight can create reports from the following sources: Rational data warehouse: This component typically contains metrics, key performance indicators (KPIs), and trends. From the data warehouse, you can create detailed list reports. Operational data source (ODS): This source contains detailed data with little analysis. You can further analyze the data by using metrics reports on the data warehouse. The data warehouse enables query optimization through data marts (STAR schemas), crossproduct reporting, and historical trends. Rational Insight uses the extract, transform, and load (ETL) process to extract data from the development domain by using JDBC or ODBC, local DBMS APIs, or an XML ODBC driver. The data is then transformed based on business rules and loaded into the data warehouse. Figure 1. Rational Insight overview diagram Rational Insight can connect to IBM Rational Asset Manager by using live integration. In a live integration, Rational Insight connects directly to a Rational Asset Manager server and extracts data from that server. Alternatively, you can set up Rational Insight to import Rational Asset Manager data into the ODS and the data warehouse by using the ETL jobs. 4

5 To configure and test the integration between Rational Insight and Rational Asset Manager for a live integration, or the ODS and data warehouse, you must complete the following steps: 1. Configure and test the XML data configuration by using the XML Data Configuration (XDC) tool. 2. Configure the IBM Cognos connection to use the appropriate ODS and data warehouse. 3. Configure and test the ETL builds and jobs by using IBM Cognos Data Manager. 4. Schedule jobs for importing data into the data warehouse. 5. Publish the Rational Asset Manager metamodel by using Framework manager. 6. Define simple test reports by using Report Studio to extract data from the Rational Asset Manager server or data warehouse. Rational Asset Manager contains a few sample reports. The final section of this document provides an example of how to run a sample report. When Rational Asset Manager and Rational Insight are integrated, you can generate various reports for live reporting and data warehouse reporting. For a list of sample reports that you can use, see the Sample reports section. Prerequisites You must use the following Rational Insight features to install and publish the Rational Asset Manager reports: 1. Data warehouse 2. Data warehouse with sample data 3. Framework manager 4. Data Manager 5. Report Server 6. XML Data Configuration Configuring the XML data configuration for Rational Asset Manager The XML ODBC driver presents XML documents in a relational view, which bridges the data structure gap between the XML and REST GET interface with the database access that Cognos requires. The mappings are specified in the XML Data Configuration tool and saved in a configuration file (.xdc) for use by the XML ODBC driver. The XML ODBC driver processes ODBC API calls into REST GET requests, and in return converts XML documents into ODBC. To modify the XDC files for Rational Asset Manager, you must complete the following procedures. Configuring the resource group for Rational Asset Manager for live reporting 1. In Rational Asset Manager, click Help > Extensions. 2. On the Extensions page, select the insight.zip file and extract its contents. In the Web Services section, note the URL of the Rational Asset Manager server. 5

6 3. Open the XML data configuration tool. From the Start menu, select All Programs and click IBM Rational Insight > XML Data Configuration. 4. Open the Rational Asset Manager configuration by clicking File > Open Configuration, and browsing to this location: unzip_directory\dataconfig\configs\live data config\assetmanager.xdc 5. Open the Rational Asset Manager resource group: a. Expand XML Data Configuration > Resources > RAM. b. Double-click Asset Manager to open the properties editor. 6. In the properties editor, provide information about the resource group: a. In the URL field, enter the URL of the Rational Asset Manager server, which you noted in step 2. Note: Open a browser and test the URL. Make sure that the URL does not end with a forward slash (/). b. From the URL type list, select Generic XML. c. From the Authentication type list, select Basic. d. Enter the user name and password, which might be admin and admin. e. Save the changes. You have now configured the connection between Rational Insight and Rational Asset Manager. f. Click Test Connection, and then click OK. You now have a specification of the resource groups as a.xdc file. Figure 2. The resource group details 6

7 Configuring the resource group for Rational Asset Manager for data warehouse reporting Repeat the process that is defined in the previous section, except use the file from this location: unzip_directory\dataconfig\configs\configurations\assetmanager.xdc Configuring the server to connect to the operational data warehouse The Rational Insight server is preconfigured to work with the sample data warehouse (SAM- PLEDW). The databases can be viewed with the IBM DB2 Control Center. Figure 3. DB2 Control Center The configuration steps in this section are required if you have not yet configured Cognos Connection to use a specific data warehouse. In the following procedure, the server is configured to connect to the operational data warehouse (RIDW). However, in your installation, the operational data warehouse might be named differently. Configuring the database connection by using Cognos Administration 1. In Rational Insight, add a signon to the RIDW data source connection. To learn how to add a signon, see Create a Signon in the Rational Insight information center, 2. Modify the RIDW data source connection to use DB2. To learn how to modify the connection, see Modify a Connection in the Rational Insight information center, 7

8 3. Modify the connection parameters for the RIDW data source connection, specifying RIDW for the DB2 database name and replacing sampledw with ridw in the DB2 connect string field. To learn more about DB2 connection parameters, see DB2 Connection Parameters in the Rational Insight information center, 4. Test the connection. To learn how to test the connection, see Create a Data Source in the Rational Insight information center, 5. Click Launch and select IBM Cognos Administration. You have now configured Rational Insight to use the RIDW database. Configuring and deploying the ETL database You must configure the ETL database to import data from the Rational Asset Manager data sources that are defined in the XDC tool (in section 2).
