Notifier events

Events are fired whenever a Notifier polls a MobiLink Listener. When an event is fired, the SQL script associated with the event is executed. You can incorporate SQL script into any of the Notifier events listed in this section. Although scripting is optional, you must script the request_cursor polling event.

There are three classifications of Notifier events: polling events, connection events, and asynchronous events. Polling events are fired every time a Notifier checks the consolidated database, and include all the events that occur between a begin_poll event and an end_poll event. Connection events are fired during the Notifier database connection. Asynchronous events can be fired at any time during the synchronization process.

Unless otherwise specified, Notifier events can be configured using any of the recommended methods. For more information about configuring Notifier events, see MobiLink server settings for server-initiated synchronization.

When a MobiLink Listener polls the Notifier, these events are fired in the following order:

Fire begin_connection event
For each poll (
    Fire begin_poll event
        Fire shutdown_query event
        Fire request_cursor event
        For all requests expired before required confirmation (
            Fire error_handler event
        Fire request_delete event
    Fire end_poll event
Fire end_connection event
