2.5.1 Flow of unidirectional message reception facility processing

The unidirectional message reception facility enables you to use the batch mode to distribute to clients a notification of startup of online operations, which is similar to batch startup of terminals in OLTP in a conventional mainframe system.

To use the unidirectional message reception facility, you execute the acceptNotification method. The client waits for a message from the server for the amount of time specified in the method, regardless of the server's status (active or inactive). If a message is sent when the server starts, the client can detect startup of the server and subsequently start user applications (CUPs).

The following figure shows the flow of unidirectional message reception facility processing.
