RSI User Thread

The RSI user thread is a client connection thread for incoming messages from another Replication Server.

It calls the Message Delivery (MD) module to determine whether to send the message to:

A data server using the DSI thread. The DSI thread is composed of a scheduler thread (DSI-S) and one or more executor threads (DSI-E).
Another Replication Server using the RSI thread.

The RSI user thread writes commands destined for other Replication Servers or databases into outbound queues. The threads involved in processes in the primary Replication Server process messages after they are stored in the outbound queues.
