Analytical Ecosystem
You must create a unique alias for every server with DNS, or in the host files, to make sure that all servers in the automatic failover cluster can connect to each other. The unique alias allows you to reconfigure automatic failover without needing a new IP address when the IP address of a server changes.
  1. Define all servers in the cluster by creating a unique alias in the DNS or the host files.
    Define the IP addresses in the /etc/hosts file if using the host file method.
  2. Add an entry to the /etc/hosts original-active and designated-standby servers to make sure that the local server resolves to a publicly accessible IP address instead of 127.0.0.1.
    This allows ARCMAIN to run on a remote Data Mover agent and connect its socket connection to the Data Mover daemon.
