Chapter 3: Control Processes 3. Edit or add the following line substituting KB with the cache size you want to allocate to each process. ReadCacheSize=KB For example, the following line allocates 16,384 KB to each process: ReadCacheSize=16384 4. Save and close the file. Tip: You can also use Configuration Manager to set the process cache size. Step for UNIX • Set the environment variable PPDS_READ_MEMORY to the size you want used for each cache. For example, the following Bourne shell command allocates 32 MB: PPDS_READ_MEMORY=32768 export PPDS_READ_MEMORY Notes • You shouldn’t set the cache size to more than 64 MB, because it may take the system more processing resources to manage the cache than it would to retrieve the data from disk again. • For a new cache size setting to take effect, you must restart each cube that is running. You can either stop and then enable the cubes (p. 34), or restart the PowerPlay server altogether (p. 15). Switch Between the Enhanced and Generic Interface To improve performance, you can switch between the Enhanced and Generic interface for folders containing cubes, or for the entire server. • Consider using the Enhanced User Interface (p. 114), which supports drag and drop and right-mouse clicking. The Enhanced User Interface can be viewed using higher level browsers and does not rely on cascading drop-down menus or menu-level filtering. • Consider using the Generic interface to improve user response times, especially for low network bandwidth environments, such as dial up lines. Generic HTML is the default for Web browsers that do not support enhanced Java-based Web pages. Steps to Use the Enhanced User Interface 1. In PowerPlay Enterprise - Server Administration, select a cube, folder, or server. 2. From the Edit menu, click Properties, and then click the Cube Settings tab. 3. Expand Display (Web). 4. In the Type box, select Enhanced. 5. Click OK. Steps to Use the Generic HTML User Interface 1. In PowerPlay Enterprise - Server Administration, select a cube, folder, or server. 2. From the Edit menu, click Properties, and then click the Cube Settings tab. 3. Expand Display (Web). 4. In the Type box, select Generic. 5. Click OK. 36 Cognos PowerPlay (R)
Chapter 4: Deploy Cubes and Reports Use PowerPlay Enterprise - Server Administration to make your multidimensional data available to analysts and report consumers. This chapter introduces the PowerPlay Enterprise - Server Administration user interface and describes the various tasks you perform to deploy your data. PowerPlay Enterprise - Server Administration PowerPlay Enterprise - Server Administration is a Java application that administrators use to configure PowerPlay servers and the cubes, reports, and folders registered on the servers. To start PowerPlay Enterprise - Server Administration: • In Windows, the PowerPlay Enterprise - Server Administrator is run through Cognos Server Administration. To launch Cognos Server Administration, from the Start menu, select Programs, select Cognos, and then click Cognos Server Administration - OLAP Cubes and Reports. • In UNIX, run the script ppsrvadm.sh located in the bin directory. After you start the program, you are prompted to connect to an initial server (p. 38). You can enter the name of your computer for local administration, or the name of another networked computer for remote administration. Any computer that you administer must be running a dispatcher. The application window is divided into two panes. The left pane shows a hierarchical tree view of the connected servers and folders. You can expand and collapse objects in the hierarchy. The right pane shows a grid view of the objects in the selected server or folder. Use the tabs to choose between Explore view and Monitor view in the right pane. Tips • To sort the objects in the right pane, click the column headings. • In Explorer mode, you can use context sensitive menus. When you select an item in the either pane, click the right mouse button and a menu of available commands appears. Depending on the view chosen, the right pane shows the following. Category Explore view Monitor view Items All objects of the selected server or folder Only active objects of the selected server or folder Status ✔ ✔ Access ✔ ✔ Enterprise Server Guide 37
