Single Event Server Mode

By default, CA Workload Automation AE is configured to run with one event server (database). This configuration is named single event server mode. You can configure CA Workload Automation AE to run with two event servers either during installation or after a single event server mode installation.

When CA Workload Automation AE is running in dual event server mode and the scheduler detects an unrecoverable error condition on one of the event servers, it automatically rolls over to single event server mode using the other event server. You can configure CA Workload Automation AE to run in single event server mode. This is useful after a database rollover.

The Event Server - CA Workload Automation AE Administrator window indicates a rollover and a switch to single event server mode in the following ways:

The Status field displays which event server is DOWN.
The A Database Rollover Has Occurred check box is selected.

CA Workload Automation AE makes these changes so that the scheduler or the application server trying to access the database are aware that it is now running in single event server mode.
