NCAFE - The Non-Cluster Aware Failover Environment (NCAFE) is an environment that enables applications that are not cluster aware to take advantage of the High Availability (HA) benefits offered by VMS Clustering. A Non Cluster Aware (NCA) application(s) running on VMS is an application(s) that does not have any knowledge of VMS clustering (lock management) and only runs on one node at a time.
The NCAFE will allow an NCA application(s) to run on one node at a time in a cluster and provide failover capability when/if necessary.
If an event causes the current node, the NCA application(s) is running, to drop out of the VMS cluster or if its NIC(s) fails, or the application fails, then the NCAFE will automatically failover the NCA application(s) and its associated IP address from the failed node to a surviving cluster member node.
