ESB Server High Availability

This section describes how Failover can be configured on the Fiorano Enterprise Server (FES). This feature allows you to specify a backup Enterprise Server as a contingency measure against the failure of the primary Enterprise Server in the Fiorano Network. If the default FES fails, the Event Processes running on the Fiorano network connect to the backup FES and continue to run. The tools do not automatically reconnect to the backup Server; the user has to manually connect them. The Fiorano Enterprise Server HA is implemented in both shared and replication mode. If there is a failure in the Active Server while it was launching an application, the Secondary Server assumes the Active role and starts launching the Event Processes again.
Figure below illustrates the failover connection on the FES.
