Event Dispatcher 
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).
