A group of logical connections is defined to SNA by the TRS administrator. Each logical connection connects a mainframe transaction processing region with a remote port on a TRS platform. Every request forwarded from a TRS to a mainframe server uses one of these logical connections to communicate with its remote partner. When a request is sent across a connection, it is called a conversation.
SNA connections are activated when a TRS is started and remain active until the TRS is shut down or deactivated.
