Modifying Default Synchronization Listener Properties with Production Values

Once you have determined the degree of secure communication you require, you may need to modify default synchronization listener property values to disable one or more ports or synchronization protocols.

1. Open SAP Control Center.
2. In the left navigation pane, select Configuration.
3. In the right administration pane, click the General tab.
4. Select Replication and click Properties.
5. Modify the protocol and port values:
   • To disable the HTTP port, unselect Port. Disabling this port means that you do not plan to use an unencrypted port, or use TLS for E2EE on this port (if you also disable all properties).
     Note: Do not unselect the HTTP port if you are using Relay Server. The RSOE cannot use the HTTPS port.
   • To change the default port value, delete port 2480 and enter a new value.
   • To disable the HTTPS , unselect Secure port. Disabling this port means that you do not plan to use HTTPS with SSL.
   • To change the default secure port value, delete port 2481 and enter a new value.
   Note: You cannot disable both ports.
6. To change any default HTTPS with SSL properties (particularly to set new values for production-ready certificates for HTTPS), modify these properties:
   • Secure sync port certificate alias – the certificate alias for secure sync.
   • Trusted relay server certificate alias – if the Relay Server trusted certificate is configured, identifies the public security certificate alias.
   Note: If you have disabled the secure port, you do not need to configure these values.
7. To change any default E2EE properties (particularly to set new values for production ready certificates for E2EE), modify this property:
   • E2E encryption certificate alias – specify the certificate alias for end-to-end encryption.
   Note: Leave E2EE values blank to disable end-to-end encryption.
