Communication Default

Synchronous communication relies on a direct connection between the client and server systems.

In asynchronous communication, a connection exists between the client and the Uniface Router for only as long as it takes to transfer the request to the Router. Once the request has been received by the Router, a local channel is opened to the Uniface Server and the request message is transferred. Therefore, with asynchronous communication, the client does not have to wait for the request to be processed before continuing.

For all component implementations, you can override this definition using the newinstance statement with the switches /sync or /async.
