Install CTE on the Teradata Database Appliance

CTE must be installed on every node in the Teradata cluster, including any Hot Standby Nodes. When you install CTE on every node in your Teradata cluster and register each node with the CipherTrust Manager, the following are required:

• You must have AES-NI key available on the host.

• The Teradata kernel must be at version 4.4.140-96.54.TDC-default, or higher, on the Teradata Database Appliance on which you plan to install CTE. Refer to CTE release notes for compatibility between CTE and the Teradata kernel releases.

• Your version of Teradata Database must be fully compatible with CTE for supporting the pdisk devices protected as IDT-Capable GuardPoints.

• The CTE Agent must be installed in /opt/teradata/vormetric. In order to specify this location, use the -d option when installing CTE. For example:

  ./vee-fs-7.3.0-135-sles12-x86_64.bin -d /opt/teradata/vormetric

  Copy
  

  Warning

  Before you install or upgrade CTE, you must stop the Teradata Database and any other applications that access the database devices directly or though the database service. Failure to stop the applications will result in a failure to install or upgrade CTE.

  

  Caution

  Be sure to install the CTE Agent in a file system with sufficient free storage space. The minimum available free space is the number of pdisks in your cluster multiplied by 63MB.
