When the CONNECTION_POLICY is not set in the DM_LOCAL_DOMAINS entry, or is set to ON_DEMAND, you may not specify multiple values for RDOM in a DM_REMOTE_SERVICES entry. If multiple values for RDOM are specified, only the first one will be used. Using multiple values allows you to specify Domains-level failover, where a comma-separated list of RDOMs can be specified. The first value listed for RDOM is the primary value; the rest are alternates.
