running IS service without LOCKFILE in 8.2

Hi I m running IS 8.2 on windows as service hence I dont want to have LOCKFILE (.lock) generated…I have done it in previous versions but seems the settings for it has changed from Server.bat to profile/bin or profile/config … I tried server.bat, setenv.bat even runtime.bat does anybody knwo settings changes required to be done in order to not create .lock file for IS8.2?
Thanks in advance

This is what I called my runserver.bat

del “C:\SoftwareAG\IntegrationServer\LOCKFILE”
C:\SoftwareAG\IntegrationServer\bin\server.bat -log none
