This book provides information about the Teradata Director Program (TDP), which resides in the mainframe client and manages communication between CLIv2 client application programs and the Teradata server. The functions of the TDP include:
Centralized operational control
Session initiation and termination
Logging, verification, recovery, and restart of client applications
Physical input to, and output from Channel Processors (CPs)
CLIv2 applications communicate with the Teradata server through TDP, avoiding the need for application knowledge of underlying Teradata Database communication protocols.
