The same configuration successfully HL7 pings two Cache implementations of VistA. Then why doesn't it work with GT.M? Regards Usha

The receiving system would be running a listener process on that node and port to accept connect requests from the client system(s). A single threaded server can accept one connection at a time (usually applied to a simple two-system interface). You could set up the client and server links on the same physical device if you wanted but it isn't typical. The concept of HL7 ping was for one Vista client system to verify that a remote Vista listener was up and configured properly on the node and port defined on the client system. When the high level ping fails, the client makes a call to DNS to see if the Vista listener has been moved to another node. If DNS returns a list of nodes, each node is pinged in sequence. If there is a successful connection on an alternate node, the client's local database is updated with the new information. The key is to have DNS contain all possible nodes that a listener could run on. That way the listener can be moved to a different server when the original one is taken out of service.

It would seem that there should be two distinct IP addresses and sending ports in a typical configuration. Or is this the concept of HL7 ping in "client/server" terms, i.e. that the client and server share the same IP address.
