Chapter 2: Configure Servers Enable Accessibility Support Cognos is committed to assisting people with disabilities, and promotes initiatives that make workplaces and technologies accessible. For example, Cognos Series 7 provides a report-reading solution for accessibility. This report-reading solution is currently available in English. In addition to the English report-reading solution, the Upfront Accessible theme can be read in English and French. By default, reports published to a PowerPlay Enterprise Server are not accessible to disabled users. To enable accessibility, you must specify the appropriate setting in Configuration Manager. Note: PDF documents that support software accessibility guidelines contain additional markup information that increases the size of the PDF file produced and, as a result, may impact performance. Steps 1. Start Configuration Manager. 2. From the File menu, click Open the current configuration. The current configuration of your computer appears in the Configuration Manager window. 3. From the View menu, click Advanced. 4. Under the Cognos PowerPlay Enterprise Server/Dispatcher component, click the Accessibility category. 5. Click the Accessible PDF property, and change the Value property to True. 6. From the Actions menu, click Validate Selection. 7. Click the Accessibility category, then from the Actions menu, click Apply Selection. Note: If you change the setting for Accessible PDF, existing saved report output in PDF format is not affected. In order to create PDF files that include accessibility markup tags, you must re-run your reports and re-save the output. PDF Server Configuration The PDF server is the component used by PowerPlay Enterprise Server that renders reports in PDF format. It works in the background whenever a user runs a report, either from Upfront or the Table of Contents. The PDF server is automatically tuned for optimal performance. However, you can adjust the settings using Cognos Configuration Manager. You can determine what settings are required by monitoring the status of running reports using the Monitor tab in PowerPlay Enterprise - Server Administration. Font Support Within PDF Generation You can specify the default font used for PDF generation. This font is used when the font specified in the report definition cannot be found on the server. Swiss 721 is the default font for Latin-1 based languages, such as the Western European languages English, German, French, Spanish, Dutch, and Swedish. For non Latin-1 languages, including multi-byte languages, the default font is one of the larger world fonts from the Andale font family. The Swiss 721 font and Andale font family are supplied with your Cognos product. Use the Default Font property in Configuration Manager to change the default font. It is also beneficial to be able to search specified directories for fonts. You can use the System Font Files Paths property to specify a search list of font directories. This property is specified as a list of directory names separated by semi-colons, such as C:/WINNT/FONTS;D:/Program Files/Cognos/cern/bin/fonts. 20 Cognos PowerPlay (R)
Chapter 2: Configure Servers Security In order to secure your data, your network administrator should first take the necessary precautions to protect all servers from unauthorized intruders. You can then configure PowerPlay Enterprise Server to better secure your sensitive data. The following section describes some of the precautions you can take. For example, • if you need to put a PowerPlay server behind a firewall, you can restrict outgoing communication to a specific Web port (p. 21) • if you want detailed reports on the data accessed, you can enable auditing (p. 72) • if you want to prevent downloading of cubes, you can disable the saving of sub-cubes (p. 25) Cognos Business Intelligence products and data are secured with Access Manager, an access control application based on user classes. With Access Manager configured, you can secure your data by allowing controlled access from any Windows or Web application. For information about configuring Access Manager and user classes, see the Access Manager online help. Depending on how the server has been configured for security, users may see Cognos Application Firewall error messages. For more information, see the Cognos Application Firewall Secure Deployment Guide. Change the Enterprise Server Port Number The PowerPlay Enterprise Server dispatchers are set to communicate on port number 8010 by default for both Windows and Web connections. You may want to change the port number if there is a conflict with another product, or for security reasons. To make server administration easier, we recommend that you configure all PowerPlay servers to use the same port number. Use the Configuration Manager to confirm or change the Enterprise Server Port Number. Notes • If you change the port number to anything other than 8010, there are cases when you must provide the new port number as part of the server name whenever you refer to the PowerPlay server. For example, refer to the server as srv2:8015 when you use PowerPlay Enterprise - Server Administration. • Dispatcher and port information is defined in the cern.csx file. In the case of a multi-machine deployment, this file may be copied to many machines. • On a Windows computer, the file cern.csx is located in the installation_location\bin directory for a dispatcher machine or the installation_location\cgi-bin directory for a gateway machine. On a UNIX computer, the file is located in installation_location/bin or the installation_location/cgi-bin directory. Restrict the Outgoing Web Port By default, a PowerPlay server listens to the gateway on port 8010 and sends back outgoing Web pages on an arbitrary port number. Under most circumstances, this is acceptable. However, if your Web server is outside a firewall, you may have restrictions on outgoing ports.
