Configuring Runtime Systems in NWDI 
In SAP NetWeaver Development Infrastructure (NWDI), you develop software that you run in a runtime environment. By deploying the software component archives (SCAs) to the runtime system, you create the connection between the software design environment – the local development environment – and the runtime environment. NWDI provides you with the option of connecting the design environment and runtime environment in a single integrated system. For more information, see The Term 'System' in CMS. In an NWDI development track, the runtime environment is an Application Server Java (AS Java).
Prerequisites
If you configure runtime systems in the track, deployment takes place in CMS during import. To enable the deployment, you must provide CMS with information about the deployment tool used by AS Java. CMS uses the message server of the runtime systems to get the required information. The connection with the message server runs through an HTTP connection. You therefore need to specify the message server’s HTTP port.
To find the port, open the SAP NetWeaver Administrator tool and navigate to 
Problem Management 
Infrastructure Management Message Server Show: Message Server Parameters
Parameter: ms/http_port 
Input Parameters
Host Name: Enter the name of the host on which the runtime system is installed.
HTTP Port of Message Server: HTTP port of the message server that belongs to the instance of the runtime system.
J2EE Engine User: The user with deployment authorization for the specified runtime system.
J2EE Engine Password: Password of the user that you entered in the previous field.
Options
Switch off automatic deployment
For the Development and Consolidation runtime systems, you can also select the Disable Automatic Deployment option. When you do this, you remove the link between automatic deployment and activation in SAP NetWeaver Developer Studio. You then have to start the deployment manually. For more information, see Starting the Deployment Manually
RecommendationWe recommend that you keep the default settings.
End of the recommendation.Integrate runtime systems into the Support Package process with Java Support Package Manager (JSPM)
Normally, you use JSPM to update the runtime systems directly with SAP Support Packages. To synchronize any modifications with the developed software components, NWDI and JSPM have to exchange information about the software components involved. You can enhance the configuration of the runtime system for this process. For more information, see Maintenance of an NWDI-Driven System Landscape.
This requires the following additional settings:
URL of AS Java
AS Java User: The user with deployment authorization for the specified runtime system.
Password: Password of the user that you entered in the previous field.
NoteIf you select the option Integrate Runtime System into JSPM Scenario, CMS makes these settings automatically during configuration with the Configuration Wizard.
End of the note.
