Use a silent uninstallation
Use a silent uninstallation to automate the removal of components on several computers that have the same components or remove components on a UNIX or Linux® environment that does not have XWindows.
Tip: If monitoring tools such as Process explorer, MMC
(Microsoft Management Console) are running during the uninstall, they will interfere with the
deletion of the services. This applies to all services in general. For example, after uninstalling
Cognos Analytics, product services such as ApacheDS, IBM Cognos, and Informix will not be fully
removed, but instead they will show in the services panel as stopped and disabled. To avoid this, do
not have any monitoring tools running while running the uninstall. Shutting down these monitoring
tools after the uninstall will also complete the removal of the services.
Procedure
Run the uninstallation wizard from a command line with parameters as follows:
Windows: install_location/uninstall/Uninstall_IBM_Cognos_Analytics.exe -i silent.
UNIX or Linux: ./install_location/uninstall/Uninstall_IBM_Cognos_Analytics -i silent
