Purpose

You can use event dispatchers to automate administrative tasks.

Event dispatchers monitor database instances. If the database instances monitored by an event dispatcher reach a certain status and trigger an event, the event dispatcher calls a previously-specified program.

The event dispatcher is a command line tool and can be used for all operating systems supported by the database system.

Implementation Considerations

The event dispatcher is a component of the MaxDB software. See the Download section and the Installation Manual for information on where to find the MaxDB software and how to install it.

For more information about the database system, see Concepts of the Database System. For quick access to all documentation and an explanation of the most important terms, use the alphabetical Glossary.

Integration

To activate and deactivate events, use the Database Manager CLI database tool. See Database Manager CLI, Using Events of the Database Instance

The database system uses the event dispatcher implicitly for automatic extension of the data area (DBM command auto_extend) and automatic update of statistics of the SQL optimizer (DBM commandauto_update_statistics).
