Uninstalling Cognos® via the console mode installation wizard

If the Cognos-Metrics installation does not complete properly, you can uninstall the primary BI server, the secondary BI server, and Transformer using the Cognos® installation wizard.

About this task

Since there will be some important information in the <Cognos Installation Path> folder, uninstall only removes the CognosBI/ and Transformer/ folders under it. To reinstall them just after you finish the uninstallation, manually delete the folder <Cognos Installation Path>.

Procedure

  1. Access <IM location>/eclipse/tools and start the following command:
    ./imcl -c
