What if I want the cluster to be less sensitive to network, especially WAN latency?
Continuent is pleased to announce that Tungsten Clustering 6.0.2 and Tungsten Replicator 6.0.2 are now available!
Our 6.0.2 release is a critical bug fix for the cluster Manager logic within a Multimaster cluster.
All current users of v6.0.0 and v6.0.1 should upgrade IMMEDIATELY!
