Server Transaction Programs

The server transaction program delivers the service that is requested by the client transaction program.

The server transaction program can run continuously, waiting for clients to begin conversations with it. But frequently, the server transaction program handles a single transaction, and is started by the APPC API to handle one specific conversation. The server transaction program begins execution when a conversation is requested, and it terminates when the conversation is finished.

An important feature of the LU 6.2 architecture is that it can start server transaction programs when client transaction programs request them. You can design your server programs according to this model and arrange for them to be started on demand.
