TDP manages communications between Teradata CLIv2 for mainframe-attached systems and the Teradata Database server. TDP executes on the same mainframe as Teradata CLIv2 for mainframe-attached systems, but runs as a different job or virtual machine. Although an individual TDP is associated with one logical server, any number of TDPs may operate and be simultaneously accessed by Teradata CLIv2 for mainframe-attached systems on the same mainframe.
