Hi,

What ports need to be open between source and target system for element replication:

  • In case both systems are not configured for gRPC
  • In case both systems are configured for gRPC
  • In case only the source system is configured for gRPC
  • In case only the target system is configured for gRPC

Thanks!

Hi Ruben,

If you add a replicated element on a DMA, it doesn't matter if that DMA is configured to use gRPC or not. This has nothing to do with it.

This replicated element needs to get its data from somewhere. A regular element gets the data from the actual device or service. With a replicated element, it will get the data from another DMA by connecting to that DMA just like Cube would do. So, it only depends on how this DMA, hosting the original element, is configured:

  • with gRPC: only TCP port 443 towards that DMA hosting the original element needs to be open.
  • without gRPC: TCP port 443 and 8004 (or whatever port which was chosen for .NET Remoting, default is 8004) need to be open towards that DMA hosting the original element

This is also nicely explained here: Replicated elements | DataMiner Docs

PS: I deliberately avoided the wording source and target system because I got confused what is what...
