>
>
> DUCC should provide the capability to move the head node, comprising the broker, database, Orchestrator, PM, RM, SM, and WS, and have the agents seamlessly switch over w/o service disruption.
> ---
> In this "static" failover implementation the agents are pre-configured with a list of potential head nodes.  Introduced into the ducc.properties file is the key ducc.head.failover whose value is a comma separated list of failover nodes:
> ducc.head.failover = node1, node2, node3...
> The agents at boot time are configured for broker failover to this set of nodes.
> If ducc.head.failover is not specified, then the failover functionality is simply not supported for the installation (e.g. no seamless transition of running agents to an alternate broker head node).
> If ducc.head.failover is specified, then the node specified for ducc.head must appear in this list.
