To uninstall IBM Cognos 8, you uninstall server components and modeling tools.
If you are running IBM Cognos 8 in
an application server environment, use the administration tool provided
with the application server to stop the application if it is running and
undeploy the Java portion of IBM Cognos 8 components. Many
application servers do not completely remove all deployed application
files or directories during an undeployment; therefore, you may
have to perform this action manually. After you have undeployed
IBM Cognos 8 components, complete the steps in this chapter
to uninstall on UNIX and on Windows .
