Chapter 2: Configure Servers To work within this restriction, you must set the CGI (common gateway interface) to communicate only on the dispatcher port. This way, all communication to and from the gateway is on the same port. Steps 1. Start Configuration Manager. 2. Click the Cognos PowerPlay Enterprise Server.Gateway.General.Restrict the Outgoing Web Port property, and set the value to True. 3. Click Apply. Change the Port for Windows Connections If you are connecting to a PowerPlay server using a Windows client application (PowerPlay for Windows or PowerPlay for Excel), you may want to restrict outbound communication to a specific port. For example, you may need to connect through a firewall. You can configure your firewall to allow TCP traffic through a specified port, and then configure the Windows client applications to listen on this port. Restricting the port number for Windows connections may affect performance if many client applications are accessing the server. Steps 1. On the computers running the Windows client applications, open the file cern.ini in a text editor. It is located in the bin directory. 2. Add or edit the following lines, replacing port_number with the port number you want to use: [PowerPlay Server - PPDSRemote] Port=port_number You can use any port number between 1025 and 65535 (inclusive). 3. Save and close the file. Configure Security on a Microsoft Web Server You can use Microsoft Internet Information Server (IIS) to control Web access to cubes on PowerPlay Enterprise Server by requiring network security information from users when they log on. In Microsoft IIS, you configure the network security using Microsoft Management Console. For information about Microsoft Management Console, see the documentation provided with the Microsoft Internet Information Server Web server. This table describes how the security properties affect access to cubes on a PowerPlay server. Check box Allow Anonymous Basic Authentication (Passwords Sent in Clear Text) Description Limits users to cubes in directories accessible by the Web server. Prompts for network security information when users access cubes using non Microsoft Web browsers. The Basic Authentication (Passwords Sent in Clear Text) check box affects user privileges. For example, if a cube is stored in a directory that a user doesn't have network privileges for, the user can’t open the PowerPlay Web page that is generated from the cube. 22 Cognos PowerPlay (R)
Chapter 2: Configure Servers Performance Monitor Define Network Security Information You can define the network security information that users enter. Typically, network security requires that users provide user IDs and passwords. For PowerPlay Enterprise Server, the network security must include the domain. For example, you register the following for a domain named europe and a user with the identifier smiths: europe\smiths Notes • Users with Internet Explorer Web browsers may not be prompted for network security information if they are already logged on to the network when they execute a request. You can use the PowerPlay Server and PowerPlay Web Cube objects in Performance Monitor to troubleshoot problems and monitor performance. The PowerPlay Server object contains counters that display information about the PowerPlay server service. The PowerPlay Web Cube object contains counters that display information about Web requests performed by PowerPlay Web for a specific cube. Both objects contain the same set of counters and they are listed below: Counter Current requests received Current queued requests Description Number of Web requests that were received in the last sampling period. Number of Web requests that are currently queued awaiting processing. Current requests completed Number of Web requests that were completed in the last sampling period. Average request time Request count base Total failed requests Total requests received Total requests completed Average time to process a Web request. Used to calculate the average. This counter is hidden from the user. Total number of Web requests that have failed since the service started. Total number of Web requests that have been received since the service started. Total number of Web requests that have been completed since the service started. These performance objects are not installed by default. You must install them manually. Steps 1. Stop the Cognos PowerPlay Enterprise Server (cern) service from Services under Control Panel. 2. From the command prompt, type ppserver -i from the installation_location\bin directory. 3. From the command prompt, type lodctr ppwebperf.ini from the installation_location\bin directory. 4. Start the Cognos PowerPlay Enterprise Server (cern) service from Services under Control Panel. 5. If the PowerPlay Server and PowerPlay Web Cube performance objects are unavailable in Performance Monitor, reboot your machine. The PowerPlay Server and PowerPlay Web Cube performance objects are now available. Enterprise Server Guide 23
