EPM System installs a single start script in MIDDLEWARE_HOME/user_projects/epmsystem1/bin, called start.bat|sh. Running the single start script on a machine in your EPM System deployment starts all EPM System services installed on that machine.
To launch the single start script from the Start menu, Select Start, then Programs, then Oracle EPM System, then Foundation Services, and then Start EPM System. Run this start script on each machine in your environment.
