Triggers and Event Alarms

Triggers based on changes to SMI tables never run. Although you can define triggers on SMI tables, triggers are activated only when an INSERT, UPDATE, or DELETE statement occurs on a table. The updates to the SMI data occur within the database server, without the use of SQL, so a trigger on an SMI table is never activated, even though the data returned by a SELECT statement indicates that it should be.

To create an event alarm, query for a particular condition at predefined intervals, and execute an SPL routine if the necessary conditions for the alarm are met.
