One of the methods to implement dependencies between job chains is using event handlers. Whenever an event is created an entry is made into the data base table scheduler_events. In the event handler the conditions are defined to add an order for the job chain to be started.
Notice that the event service will not work with data base H2.
Events are processed by a JobScheduler Instance. This could be a Supervisor JobScheduler if a Workload JobScheduler is registered with that instance otherwise the Workload JobScheduler is used.
The The events can be monitored with with the JOC Cockpit web interface, which replaces the JID - JobScheduler Information Dashboard interface which is deprecated as of JobScheduler Release 1.12.0.
Event Service
Before events can be used the event service has to be installed. It is part of the JobScheduler installation if ordered configured within the installation procedure.
But it is also possible to install the event service The Event Service can also be installed in an existing JobScheduler instance. For more information for this purpose have a look at information see How to install the Event Service feature in JobScheduler.
The job chain scheduler_event_service is running in predetermined intervals or whenever an event is created and . The event service checks all .xml data files in folderthe $SCHEDULER_DATA/config/events folder for information matching the active events which are stored in the data base database table . All job chains within the actual live folder may be concerned.

The event handler is a .xml data file which contains the definitions of the events and the commands which are triggered .
For each job chain chain started by events we need an action to be defined in the event handler. An action has the two parts:
...
An event is uniquely defined by event class and event ID. Together with and/or/not the events of a group are combined to the condition.
In the command part the order Order is defined to start the job chain Job Chain as soon as the condition becomes true. It It is also possible to use the command add event for creating command to create new events.
Every event which is used in the condition has to be deleted from the database with the command remove event command .
