2.6.1 Overview of the facility for receiving one-way messages from the server

The facility for receiving one-way messages from the server can be used to deliver online start signals concurrently to the client. This is analogous to OLTP of a mainframe starting all terminals at one time.

To use the facility for receiving one-way messages from the server, issue the dc_clt_accept_notification_s function. This function allows the client to wait for a message from the server within the time specified for API regardless of the server state whether it is active or inactive.

When the server sends a message at startup, the client detects the server startup and is ready for starting a user job (CUP). The following figure illustrates the one-way message reception function.

The following figure shows the processing flow for the facility for receiving one-way messages from the server.
