Running multiple clusters on a single server pairs on CitectSCADA 2018 R2

I had 3 clusters setup running fine in a test environment on V8.1 on the latest update. Today, I upgraded to v8.2, ever since, the alarms don't work, be the Example_SA project alarms work fine. I looked in the trace logs for the alarm server, there are countless errors with refused connections, the firewall is disabled on my machine too. It's not a privilege issue either.

2019-09-11 13:44:22.941 -07:00 21256 0 Error Transport TcpipTransport::EndConnect() [CLIENT 0.0.0.0:57459 --> 127.0.0.1:2082 #1] SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:2082
2019-09-11 13:44:25.168 -07:00 27936 0 Error Transport TcpipTransport::EndConnect() [CLIENT 0.0.0.0:57472 --> 127.0.0.1:12082 #2] SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:12082
2019-09-11 13:44:27.424 -07:00 15584 0 Error Transport TcpipTransport::EndConnect() [CLIENT 0.0.0.0:57492 --> 127.0.0.1:22082 #3] SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:22082

I had to manually define the port numbers 12080 and 22082 for cluster 2 and 3 respectfully. Again, this work perfectly in v8.1.

I also get a hardware alarm from each of the running Alarm servers - Data Not Ready.

  • G'day Chris,

    When you say it works in Network Mode, but not standalone. Are you making any configuration changes when switching between those modes? Is SECVS002 and 4 on the same computer (i.e. dual nic) or are they separate computers?

    Is the IO and Alarm configured to run on the same computer? (when running stand-alone)
    Are you having IO problems as well? Or just Alarm? Do trends work?

    Do you have the DNS Name field configured for the stand-alone computer? (and does it match the host name of the computer you are running on.) This is essential for encryption to work as certificate validation can only be done with host names.

    cheers,
