If you use the applications.xml file as part of a custom application portlet, all Application Tier Components computers in a distributed environment must reference the same applications.xml file. If you have multiple instances of the applications.xml file, they must be identical.
Note: The steps are required only if you want to use the Extended Applications portlet, which is included with the IBM Cognos 8 software development kit.
On the Application Tier Components computer, start IBM Cognos Configuration.
In the Explorer window, under Environment, click Portal Services.
In the Properties window, click the Value next to Location of ’applications.xml’.
Replace localhost with a valid host name or IP address and, if necessary, replace the default port number.
From the File menu, click Save.
You can now deploy the Cognos portlets to your portal server. For instructions, see the Administration and Security Guide.
