The installed SAP NetWeaver Application Server for Java (AS Java) has a preconfigured set of communication ports that are used both for internal and external communication.
If some of these ports are already in use by other processes running on your machine, you may need to change the ports of the conflicting processes. If this is not possible, you may change some of the AS Java ports. If you have trouble connecting to a server, check if the requested port is active and bound to the requested network interface.
To change the Java instance ports, refer to: icm/server_port_<xx>
To change the Message Server port, refer to: Message Server Parameters .
