Before you install a new version of Teradata Tools and Utilities packages, you must use the uninstallation script, uninstall_ttu.sh, to uninstall previous versions of the packages.
The script uninstalls dependency packages in the correct order.
The script is located on the installation media in the root directory.
When the uninstallation script is executed from the install script, it prompts you to choose whether to uninstall packages from previous versions of Teradata Tools and Utilities and leave any currently installed versions installed.
- install another version of Teradata Tools and Utilities (a version other than the existing one)
- decommission Teradata Tools and Utilities on a particular system
- Teradata Call-Level Interface version 2
- Open Database Connectivity (ODBC) Driver for Teradata
When you run the script, you can specify individual packages to be uninstalled. Teradata recommends that you uninstall the dependency packages (CLIv2, PIOM, TDICU, and TeraGSS) last; however they can be uninstalled individually regardless of the order.
The script does not require any parameters to execute. When the script runs, all information within the script is displayed.
The script uses system packaging commands to uninstall packages, so it must be executed as root (or with root privileges).
