Uninstalling on a Load-Balanced System

Uninstalling a load-balanced system requires removing the application files from each application server and the Collaboration server. After running the Uninstall option on one application server, that application server, the file system, and the database will be removed. Use the Uninstall Appserver option to remove the application files on the Collaboration server and the other application servers. To uninstall app server only, add the -a option to the command, denoted with [-a] as optional in the examples below.
