Checking an Event Alert
How Check Event Alert Works
Once you define an event alert to monitor a table for inserts and/or updates, any insert or update to the table will trigger the event alert. When an insert or update to an event table occurs, Oracle Alert submits to the concurrent manager, a request to run a concurrent program called Check Event Alert (ALECTC). The concurrent manager runs this request according to its priority in the concurrent queue. When the request is run, Check Event Alert executes the alert Select statement. If the Select statement finds exceptions, Check Event Alert performs the actions defined in the enabled action set(s) for the alert. If the Select statement does not find any exceptions, Check Event Alert performs the No Exception actions in the enabled action set(s) for the alert.
How to Optimize Event Alert Request Handling
You can have your system administrator configure your concurrent managers to optimize event alert request handling. Define one concurrent manager to run only the Check Event Alert program (ALECTC). Define all other concurrent managers to run all other programs except the Check Event Alert program.
