Cause:
A DA-MP is not sending heartbeats to the IPFE.
Diagnostic Information:

Wireshark is the tool to monitor if the DAMP is sending a heartbeat to IPFE.

Follow these steps to diagnose the issues:

  1. From the SO GUI, navigate to IPFE, and then Configuration, and then Target Sets, and then TSA#, and then +; and at least one DAMP server XSI IP should be present.

    If yes, go to step 2.

  2. Log into the IPFE server.
    1. Ping <the DAMP server XSI IP>
    2. Telnet <the DAMP server XSI IP> <monitoring port, default 9675>

      If steps a or b fail, go to step 3.

  3. ssh admusr@<DAMP server XMI>.
    1. Run the sudo netstat -anop | grep <monitoring port, default 9675> command to see if there is a TCP listen socket on that DAMP XSI IP.

      If yes, check the DAMP XSI network (hardware and software).

      If no, check the configuration of the DAMP.

Recovery:

  1. Check the status of the application servers by navigating to the Status & Manage, and then Server page.
  2. Consult the application server's documentation for recovery steps.
  3. If the application server is functioning, check for network connectivity issues between the IPFE and the application server.
  4. It is recommended to contact My Oracle Support if further assistance is needed.
