Uninstalling CTP

search

Please Note:

Uninstalling CTP

This section contains the following topics:

Uninstall CipherTrust Teradata Protection

When trying to uninstall CTP on a node, the uninstaller detects the presence of the cluster and will try to uninstall CTP from the other nodes that contain the same version of CTP. If there is only a single node, it uninstalls CTP from that node.

The uninstall script also ensures that the Cryptoserver Daemon is not running on any single node before uninstalling.

Note

Do not call the uninstaller from within /opt/vormetric. You must uninstall from outside of this location.

  1. 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

    Enter password for thales user:

    Confirm password for thales user:

  2. Uninstall the VAE executable on Teradata.

    rpm -qa | grep vae

vae-td14.10-6.3.0-94

rpm -e vae-td14.10-6.3.0-94

  3. Uninstall files in /opt/vormetric/DataSecurityExpert/agent using /opt/vormetric/DataSecurityExpert/agent/key/bin/uninstall. These include:

    • CipherTrust key agent

    • /opt/vormetric/DataSecurityExpert/agent/pkcs11/teradata/udfs/install_udfs.bteq.sample

    • /opt/vormetric/DataSecurityExpert/agent/pkcs11/teradata/udfs/<renamed bteq.sample file>

    • /opt/vormetric/DataSecurityExpert/agent/pkcs11/Teradata/bin/vormetric_local_crypto_server

  4. Uninstall any files that are present in /etc/vormetric/ with rm -f.

  5. Remove the init.d script to start the local crypto server.

    Delete /etc/init.d/vormetric_local_crypto_server

Automated Uninstall over a Teradata Cluster

The intent of this feature is to detect a cluster and ensure that the uninstall is performed on all nodes in the cluster.

Note

You must ensure that the Cryptoserver Daemon is not running on any single node before the uninstall begins.

When trying to uninstall CTP on a node, the uninstaller detects the presence of the cluster and tries to uninstall the same CTP on the other nodes. If there is a single node, it also uninstalls the CTP from that node as well.

The uninstaller is located in the following directory:

/opt/vormetric/DataSecurityExpert/agent/pkcs11/teradata/bin

Warning

The uninstaller cannot be called from /opt/vormetric or its sub-directories. You can call the uninstaller from any other directory.

To uninstall CTP:

  1. Remove Teradata UDFs (user-defined functions) by default in a specific database named "thales". Either drop the database or remove the UDFs by running the following binary file:

    # cd /opt/vormetric/DataSecurityExpert/agent/pkcs11/teradata/udfs

# ./drop_udfs.bteq

    Enter password for thales user:

    Confirm password for thales user:

  2. Enter the following:

    # /opt/vormetric/DataSecurityExpert/agent/pkcs11/teradata/bin/vptd_uninstall
