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

Stop the Cognos® server from the application server list on the IBM® WebSphere® Deployment Manager.
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.
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.
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.
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.
