Uninstall CipherTrust Teradata Protection

Note

Do not run the uninstaller from the /opt/vormetric directory. Run it from a directory outside /opt/vormetric.

Remove Teradata UDFs by default in a specific database named "thales". Either drop the database or remove the UDFs (user-defined functions) by running the following binary file:
```
# cd /opt/vormetric/DataSecurityExpert/agent/pkcs11/teradata/udfs

# ./drop_udfs.bteq
```
This prompts the user to enter their Thales User password.

Uninstall the CTP rpm on Teradata.

{{{{rpm -qa | grep ctp
ctp-td20.00-6.6.1-1}}}}
rpm -e ctp-td20.00-6.6.1-1

Uninstall any files that are present in /etc/vormetric/ with rm -f.
Remove the init.d script used to start the local crypto server.
```
rm -f /etc/init.d/vormetric_local_crypto_server
```
