If you have an earlier version than 15.10.10 of Teradata Tools and Utilities installed, then use the uninstallation script uninstall_ttu.sh to uninstall packages installed by that version before you install a new version.
If you have a 15.10.10 or later version of Teradata Tools and Utilities installed then you will have to option to remove that release before installing 16.20 or keep it (for more information, see Multi-Version Support).
The script uninstalls dependency packages in the correct order.
The script is located on the installation media in the root directory.
- Remove Teradata Tools and Utilities products
- 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, and TDICU) 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).
