Fully Qualified Domain Names

A fully qualified domain name [FQDN] takes the form <host>.<domain>, e.g. xx.xyz.com. When viewing the SocketNodes, displayed by RPC Diagnostics, you may notice that the MachineNode names are machine names, whereas the SocketNode names are FQDNs. This is because SocketNode names are obtained by reverse name lookup, converting the IP of the connected [remote] machine to a name. Name resolution, particularly via DNS, may yield such a name.

When specifying server lists, you must provide machine names [not FQDNs] in the configuration files and when acquiring an application from another machine.

Then configure name resolution to resolve names within the context of the appropriate domains by specifying domain suffixes during DNS configuration on the client machine [see diagram] and leave the mapping to DNS.

In the following diagram, a machine called XX will be searched for, firstly, within the trihedral.com domain and then in the xyz.com domain.

This means that machine names must be unique within the domains that RPC Manager can address, e.g. using the above configuration, RPC Manager will treat xx.trihedral.com and xx.xyz.com as the same machine [even if they are not].
