Integration Server can run as either a Windows application or a Windows service.
*Use a Windows application if you want to control when the Integration Server initializes. When Integration Server is a Windows application, you must manually start it.
If you installed the Integration Server as a Windows service and now want it to be a Windows application, you can manually remove the Windows service for the Integration Server. After removing the Windows service, the Integration Server will still be available as a Windows application. See Switching the Server from a Windows Service to a Windows Application.
*Use a Windows service to have Integration Server automatically initialize when the machine on which it is installed initializes. When you use a Windows service, you do not have to manually restart Integration Server following a machine restart.
If you installed Integration Server as a Windows application and now want it to be a Windows service, you can manually register the Integration Server service.
See Switching the Server from a Windows Application to a Windows Service.
Note:
If you want the Integration Server to prompt for the master password for outbound passwords at server initialization, do not run it as a Windows service. For more information about outbound passwords and the master password, refer to Configuring Integration Server for Secure Communication.
You can run multiple Integration Server instances as applications and multiple Integration Server instances as services on a single machine. For example, you can run two instances of Integration Server as an application and two instances of Integration Server as services on the same machine.
