In order to keep the Replication cluster stable and running, it is important for the system to be resilient to failures. Failures are caused by either software bugs or hardware problems, and can happen at any time. In case a server goes down, failure handling, failover and reconfiguration of the Replication cluster needs to be automatic, so as to minimize downtime.

Fail-over handling differs for the following 3 scenarios:

-       master failure

-       backup master failure

-       slave failure

ClusterControl™ automates fail-over and reconfiguration of the Replication cluster in all the above scenarios.
