The Controller Link Is Missing in IBM Cognos Connection
You completed a distributed installation integrating IBM® Controller with IBM Cognos® Business Intelligence. When you access IBM Cognos Connection to start IBM Controller, the Controller link does not appear on the IBM Cognos Connection start page or on the studio bar.
Ensure that you installed the Gateway Integration Enabler on the IBM Cognos Gateway computer, and the IBM Cognos Connection Integration Enabler on the IBM Cognos application servers.
If you started the IBM Cognos service before the IBM Cognos Connection Integration Enabler was installed, you must restart the IBM Cognos service.
You may also need to verify that the URI for IBM Cognos Connection is correct. The URL parameter in the ControllerLaunch.xml file sets the link associated with Controller in IBM Cognos Connection. For a distributed installation, this must be the full URL for the Controller Client Distribution Server.
