Script for creating the EPMSystem Admin service. This example covers EPM System11.

Create the CMD file under: D:\Oracle\Middleware\user_projects\domains\EPMSystem\InstalAdminService.cmd

File Contents:

SETLOCAL
set DOMAIN_NAME=EPMSystem
set USERDOMAIN_HOME=D:\Oracle\Middleware\user_projects\domains\EPMSystem
set SERVER_NAME=AdminServer
set PRODUCTION_MODE=true
cd %USERDOMAIN_HOME%
set WLS_USER=epm_admin
set WLS_PW=wlpassword
call %USERDOMAIN_HOME%\bin\setDomainEnv.cmd
call "D:\Oracle\Middleware\wlserver_10.3\server\bin\installSvc.cmd"
ENDLOCAL

Correct the WL Password and paths to fit your installation, normally just updating the drive letter will do. Run the batch file.

If all is well it will create an entry at:
HKLM\SYSTEM\CurrentControlSet\Services\beasvc EPMSystem_AdminServer

The memory settings can be tweaked here as well as updating the log file entry if detailed service start-up information is needed.
