Configuration of Secure Communication with the WebStart Client 

Secure P4 is used for communication between the WebStart client and the Enterprise Services Repository and the Integration Directory.

To enable secure P4, create or maintain the following properties in your exchange profile:

●      com.sap.aii.connect.rmi.protocol

This property contains the protocol used for P4 communication. Possible values are P4 (default), P4S (secure), and P4HTTP (HTTP tunneling).

●      com.sap.aii.connect.repository.rmiport.ssl

This property contains the P4 port number of the AS Java where your Entire Services Repository is installed.

●      com.sap.aii.connect.directory.rmiport.ssl

This property contains the P4 port number of the AS Java where your Integration Directory is installed.

It is a prerequisite that your AS Java is configured for SSL. More information: Configuring the Use of SSL on the AS Java.

If you are working in a high-availability environment, you must also maintain the following properties:

●      com.sap.aii.connect.repository.mshttpsport

●      com.sap.aii.connect.directory.mshttpsport

These properties contain the HTTPS port number of your message server.

It is a prerequisite that the message server of the SCS Instance is configured for SSL. More information: Metadata Exchange Using SSL.

HTTPS is then used for the communication with the message server and secure P4 is used for the communication with the WebStart client.
