Chapter 4: Deploy Cubes and Reports Add a Folder Add a Collection A bold setting means that it no longer acquires settings from its parent, unless you reset those settings by clicking the Reset or Reset All buttons. At the folder level, you can also force descendant objects to acquire new settings by clicking the Reset Descendants button. A folder is a container that can hold any combination of cubes, reports, or other folders. Use folders to organize and administer related objects in a hierarchy. Steps 1. In PowerPlay Enterprise - Server Administration, select a PowerPlay server or a folder. 2. From the Insert menu, click Folder. 3. In the Name box, type a name for the folder. Tip: You can click the browse (...) button to locate a folder. If folders on mapped network drives do not appear, type the UNC location in the Name box and do not use drive letters. For example, \\server_name\source_location. 4. Specify other settings if required and click OK. Note • If you specify a folder data source, the folder becomes a collection (p. 40) and takes on special characteristics. • Use Drag and Drop to move folders and collections to another location on the same server. To copy folders or collections, use CTRL and drag. A collection is a folder with a physical directory as a data source. This property enables the contents of a collection to be dynamically updated with the contents of the directory. Aside from that, a collection is still a folder that contains child objects that acquire the folder settings by default. With a collection, you can add cubes and reports by copying the source .mdc and .ppx files to the directory referenced by the collection. This offers a quick way to update an undetermined collection of items on a production system. Steps 1. In PowerPlay Enterprise - Server Administration, select a PowerPlay server or a server. 2. From the Insert menu, click Folder. 3. In the Name box, type a name for the folder. 4. In the Folder Source box, select a directory. The directory should contain data source files (.mdc or .ppx), or other directories that contain data source files. 5. Specify other settings if required and click OK. Cubes and Reports A substantial proportion of the tasks that you perform as a PowerPlay server administrator probably entail distributing cubes and reports to your users. From an administrative perspective, the cubes and reports are iconic representations of the data sources or mirror references of the data sources. For example, when you add a cube, you don’t copy the actual cube data source (an .mdc file) to a directory. Also, folders are virtual groupings of cubes, reports, or other folders, and not representative of a directory. Therefore, any reference to cubes or reports in the following sections also applies to the folders of cubes and reports. 40 Cognos PowerPlay (R)
Add a Cube or Report Chapter 4: Deploy Cubes and Reports To add a cube or report, you identify the server to be published to and specify a cube or report source. The server that a cube or report is available from is the dispatcher on which the cube or report is registered. Steps 1. In PowerPlay Enterprise - Server Administration, select a PowerPlay server. 2. From the Insert menu, click Cube or Report. 3. In the Name box, type a name for the cube or report. 4. In the Cube Source or Report Source box, click the ellipsis button. 5. Select an .mdc or .ppx file and click OK. Note: If you specify a .ppx file, the associated cube must also exist (p. 13) on a PowerPlay server. Tip: If cubes or reports on mapped network drives do not appear, type the UNC location in the Name box and do not use drive letters. For example, \\server_name\source_location. 6. Specify other settings if required and click OK. Notes • Cubes and reports are automatically enabled when you add them. • When you specify the data source, you can use the standard file notation for your operating system, such as C:\Cubes\Imports.mdc on Windows, or /cubes/imports.mdc on UNIX. You can also use a UNC path, for example //srv01/cubes/imports.mdc. If you want to browse using a UNC path, you must type the computer name and share directory in the Look In box, and then click OK to refresh the Contents list. • In Windows, services can log on only to system directories, by default. To allow PowerPlay Enterprise Server to access remote data sources, for example, to use a UNC path, you must give PowerPlay Enterprise Server account logon privileges for the remote systems. For information about configuring these privileges, see the Windows documentation about using the Services application of the Control Panel to configure Startup properties. • In UNIX, PowerPlay Enterprise Server must have access to the data sources that reside on the remote computer. You must grant this using standard UNIX permissions. Add a Mirror Reference A mirror reference is a mapped cube or report that forwards incoming requests to be processed remotely instead of on the computer where the object is added. Use mirror references to distribute the processing load among processors and servers. When you add a cube or report to PowerPlay Enterprise Server, you can specify a data source alone, a mirror reference alone, or both. You can also specify several mirror references for a cube or report (p. 29). Steps 1. In PowerPlay Enterprise - Server Administration, select a cube or report. 2. From the Edit menu, click Properties. 3. In the Cube Mirror References or Report Mirror References box, click the ellipsis button. 4. In the Select Mirror References dialog box, click the Add button. 5. In the Add Mirror Reference dialog box, select the mirror reference. 6. Click OK in all the dialog boxes. Notes • The cube or report that you want to mirror to must have sharing enabled. See the Settings tab (Options). Enterprise Server Guide 41
