The wide-area connector (wac) is a failover Application resource that ensures communication between clusters.
Figure: Wide-area connector (wac) process is an illustration of the wide-area connector process.
The wac process runs on one system in each cluster and connects with peers in remote clusters. It receives and transmits information about the status of the cluster, service groups, and systems. This communication enables VCS to create a consolidated view of the status of all the clusters configured as part of the global cluster. The process also manages wide-area heartbeating to determine the health of remote clusters. The process also transmits commands between clusters and returns the result to the originating cluster.
VCS provides the option of securing the communication between the wide-area connectors.
