States are defined for each database instance; when the database instance reaches a certain state, an event is triggered.
The database system recognizes the following event types:
·
Events that are
always triggered and cannot be deactivated
The system default that triggers the event cannot be changed.
· Events that can be deactivated
·
Events for which
the system default that triggers the event can be changed
For certain states, multiple values can be defined, each of which can trigger
an event.
You can use this event type, for example, to receive a warning when a certain filling level in the log area is reached, or when the optimizer statistics need to be updated.
