Heartbeat is configured to switch over to the backup node if the master node happens to go down.
By replicating the entire configuration tree from the actual deployment manager node to another application server node, the deployment manager can be quickly restarted on the backup node.
This example presents a simple ha cluster that consists of three nodes: a master node, a backup node, and a management node.
Creates a modified deployment manager startup script for use with the configuration maintained with the backup node.
AS with the other hardware replication technologies, although the IASP is not accessible on the backup node while its actively replicating, the node itself is available to do other work.
