The installation process creates a test system and a production system. A new release is initially installed on the test system, where the software is exercised and verified. The software is then moved to the production system.
The installation process covers the steps from the media to the test system to the production system. The data set names provided distinguish between release media, test, and production libraries.
A Teradata software installation should not affect current production client sessions until an Initial Program Load (IPL) is performed. For users, the install process is transparent except during the time that the IPL is performed to incorporate the new software into the client environment.
