Uninstalling Cognos Business Intelligence server

You uninstall Cognos® by uninstalling the Cognos Business Intelligence server and Cognos Transformer and removing the powercube refresh scheduler .

Procedure

  1. Stop the Cognos server from the application server list on the IBM® WebSphere® Deployment Manager.
  2. Remove the Cognos server node from the Deployment Manager by navigating to System Administration > Nodes and then select the node containing Cognos and click Remove Node.
    Note: Do not remove the node if other servers on this node should remain in the DMGR cell. If this node should remain in the cell, please use a new node for the Cognos server that will be used with Connections 5.0.
  3. Uninstall the Cognos application on the IBM WebSphere Deployment Manager if it still exists by navigating to Applications > Application Types > Websphere enterprise applications > Select Cognos and then click Uninstall.
  4. On the machine where the Cognos application is installed, remove the Cognos server instance in WAS by using the following command:
    wsadmin -lang jython -conntype NONE -c "AdminServerManagement.deleteServer('NODE_NAME', 'cognos_server')"
    Where NODE_NAME is the name of the node that the cognos_server is in. Also, change cognos_server to be the actual server name if that has been changed. This command is run from the $WAS_HOME/bin folder.
  5. Make sure that the following Cognos processes have stopped before proceeding to the next step.
    • IBM AIX® or Linux™: cgsServer.sh and CAM_LPSvr processes
    • Microsoft™ Windows™: cgsLauncher.exe and CAM_LPSvr processes
    These processes should have stopped within a few minutes after the Cognos application stopped.

    1. At the command prompt, enter the following command:
      • Windows: uninst -u
      • UNIX™ or Linux with XWindows: ./uninst -u
