Uninstall Cognos Business Intelligence server

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

1. Stop the Cognos server from the application server list on the IBM WebSphere dmgr.

2. Remove the Cognos server node from the dmgr by navigating to System Administration > Nodes and then select the node containing Cognos and click Remove Node.

   Do not remove the node if other servers on this node should remain in the dmgrGR 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 dmgr 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 :
   wsadmin -lang jython -conntype NONE -c "AdminServerManagement.deleteServer('NODE_NAME', 'cognos_server')"

   Where NODE_NAME is the name of the node 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 the following Cognos processes have stopped before proceeding to the next step.

   • IBM AIX or Linux: cgsServer.sh and CAM_LPSvr processes

   • Windows: cgsLauncher.exe and CAM_LPSvr processes

   These processes should have stopped within a few minutes after the Cognos application stopped.

6. From the operating system command line, change to the Cognos_BI_install_path/uninstall directory.

   1. At the command prompt:

      • Windows: uninst -u

      • UNIX or Linux with XWindows: ./uninst -u

      • UNIX or Linux without XWindows: ./uninstnx -u -s

   2. Then follow the prompts to complete the IBM Cognos Business Intelligence Server uninstallation.

7. Delete the folder that Cognos Business Intelligence Server was installed.

8. From the operating system command line, change to the Cognos_Transformer_install_path/uninstall directory.

   1. At the command prompt:

      • Windows: uninst -u

      schtasks /delete /tn MetricsCubeDailyRefresh /f
      schtasks /delete /tn MetricsCubeWeeklyRebuild /f
