3.1 ComAgent Configuration on DSR

For Comagent configuration, go to the Communication agent tab on Active DSR NO GUI and configure UDB DB Server IMI IP as remote server.

Note:

  • If DSR and UDR deployment are in the same network, use UDR IMI IP as Comagent Remote Server Configuration.
  • If DSR and UDR deployment are in a different network, use UDR XSI IP as Comagent Remote Server configuration.

For this, add new XSI Interface on both DSR and UDR side for Comagent Communication. Ensure that newly added XSI interface are Desktop routable and are accessible from both the sides.

Note:

Do not use DSR signaling Interface (XSI Interface) for comagent communication.

  • Remote Server Configuration: Configure UDR DB as Remote Server.
  • Connection Group configuration: Add previously configured Remote Server to the STPSvcGroup Connection Group.

    Note:

    • This "STPSvcGroup" routed service is common for DCA and vSTP application.
    • Restart MP servers to make the Comagent service/connection up.
    • The following error is encountered, when the traffic is around 5.3k on each MP during the performance run:
      • Communication Agent Reliable Transaction Failed: Communication Agent Reliable Transaction Failed.
      • DCA to UDR ComAgent Error: DCA failed to send query to UDR due to ComAgent Error.
      • Communication Agent Transaction Failure Rate: The number of failed transactions over the sampling period exceeded the configured thresholds.

      To improve efficiency and to avoid the above issue, use the xsi2 interface for comagent connections between DSR and UDR.

  • Steps to Restart the MPs Server: Go to the Active DSR NOAM status & Manage section, select the MP server and restart the MP server by clicking the Restart button.
