Use notifications to register multiple client applications with OpenSwitch and provide asynchronous event notification within the server. When the client application receives an event notification, it can take appropriate action; for example, send an e-mail message, as illustrated in Figure 7-1.
Figure 7-1: Using notifications
OpenSwitch supports these registered procedures to create notification events:
np_req_srv – notifies the client that a connection blocked a request for the name of a remote server.
np_switch_start – notifies the client that the switching process has been manually started via rp_switch.
np_switch_end – notifies the client that switching process started via rp_switch has ended.
The next section describes each registered procedure.
