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.

  • Olivier,

    We run a few systems with multiple clusters on the same server pairs, so we are familiar with setting the port numbers in this case. If you look at my screen shot above, you'll see the port numbers are blank for the first cluster, only the second and third cluster server pairs have the ports numbers defined. If there are better port numbers to use, please let us know, I just added a 1 front of the second cluster and a 2 in front of the third cluster.

    I have the PC name set to 'localhost', just like the 'Example_SA' project...that works in 'Stand-Alone' mode. That why I think it may be a multi-cluster issue, and maybe even those port numbers.
