Valid Node Checking for Registration

To allow database registration with a global service manager, perform VNCR configuration using auto-VNCR or gdsctl add invitednode.

The valid node checking for registration (VNCR) feature provides the ability to configure and dynamically update a set of IP addresses, host names, or subnets from which registration requests are allowed by the global service manager. Database instance registration with a global service manager succeeds only when the request originates from a valid node.

By default, the Global Data Services framework automatically adds a VNCR entry for the host on which a remote database is running each time the gdsctl add database command is run. The automation (called auto-VNCR) requires that the host name entry exists in either the local hosts file or in the name server. If the remote host is identified by a different name on any of the nodes on which the global service manager runs, then the Global Data Services administrator must manually add VNCR entry to the Global Data Services catalog by running the gdsctl add invitednode command.
