Dual Event Servers

CA Workload Automation AE can run with two event servers. CA Workload Automation AE keeps these two event servers synchronized, which provides complete recovery when a failure occurs on one of the event servers. These two event servers contain identical data, including object definitions and events. CA Workload Automation AE reads from one event server and writes to both the event servers simultaneously.

When the scheduler processes events, it reads from both event servers. If it detects an event on one event server and not on the other, it copies the missing event to the other event server. Therefore, a temporary problem in getting events to one of the event servers does not interrupt processing.

Note: To avoid a single point of failure, the two event servers must reside on two different data servers running on different computers. For more information about installing, configuring, and using dual event servers, see the Windows Implementation Guide.
