If the webMethods instance has been installed as an application and you would like to start it up as a windows service, you can create a service wrapper for server.bat.

1. Simply run the <IS_HOME>\support\win32\installSvc.bat file. This file will create a windows service wrapper for server.bat, however the settings from server.bat need to be copied over to the registry. These settings include jvm memory values and everything else defined as a variable in server.bat. These settings can be changed in server.bat but that does not necessarily indicate that the windows service will use these settings.
2. To update the IS windows service with the settings mentioned above, first make changes required to server.bat. Then run

   server.bat -service wmIS
   

   This will update the parameters for the service identified by "wmIS"
