Use

You start the Event Dispatcher and thus automate the reactions of the database system to particular events. In the configuration file of the event dispatcher you define how the database system should react, and to which events.

Prerequisites

     You have created the configuration file for this event dispatcher (see: Configurating for the Event Dispatcher)

     The events for which the handling is described in the configuration file, are active.

Note

To activate an event see Database Manager, event_set.

You can find an overview of the events you can activate and deactivate in Concepts of the Database System, Structure linkOverview of Database Event Categories.

You do not need to activate the special events of the event dispatcher

Process Flow

...

       1.      You add a new definition to the configuration file of the event dispatcher using the addcommand.

Note

If no configuration file exists yet, the event dispatcher then creates a configuration file when the add command is executed.

       2.      If you have not yet started the event dispatcher, start the event dispatcher with this configuration file using the startcommand.

Result

The event dispatcher monitors the database instance.

If the database instance monitored triggers an event, the event dispatcher analyzes the event. If the latter finds an entry in its configuration file, the event dispatcher then calls the program specified and transfers any necessary parameters to it.
