To require confidentiality by host group, you must set up host groups:
- A Teradata Customer Service representative configures PDE to define multiple host groups using the Vconfig utility. Each host group appears as a separate HGID in the vconfig.txt file.
- A Teradata Customer Service representative configures the database to define multiple hosts using the Configuration utility ADD HOST command. Each host must include the same vprocs as the corresponding host group in Vconfig. You can verify the current host configuration with the LIST command.
- The network administrator assigns multiple aliases (tdpids) to the Teradata Database system, and maps each tdpid, which corresponds to a configured host group, to a set of COP names and IP addresses.
- The network administrator assigns a Teradata client or group of clients to a single tdpid that corresponds to a host group.
