5.13. Replicator Fencing

Version Support: 2.0.4

Continuent Tungsten can be configured to handle failures during replication automatically and to fence the failure so that the issues do not lead to issues with the rest of the cluster, which may lead to problems with applications operating against the cluster. By default, the cluster is designed to take no specific action aside from indicating and registering the replicator so that the node will be identified as being within the DIMINISHED or CRITICAL state.

This behavior can be changed so that the failed replicator failure is fenced, with configuration operating on either the master, or slave replicators. When fencing has been enabled, the node will be placed into either the OFFLINE state if the node is a slave or a failover will occur if the node is a master.
