Creating the Teradata User Defined Functions (UDFs)

Mon, 01 Jan 0001 00:00:00 +0000

Before creating the UDFs, ensure that the following prerequisites are met:

You have installed the Teradata Data Warehouse Protector on all the nodes.
When installing the Teradata objects, you must specify the maximum data size to be allocated by the UDFs. This value should not exceed 500 MB.
- When you calculate the data size, ensure that you also consider the space for the overheads.
  For example:
  - For the data that would be tokenized using non-length preserving tokens, you must add an overhead of approximately 6% to the original data size.
  - For the AES-encrypted data, with the blocks of 16 bytes, you must add an overhead of an additional 16 bytes to include CRC or IV.
The database user that installs the UDFs must have the following privileges:

Installing the Teradata User Defined Types (UDTs)

The UDTs allows you to create the data-types that can be used as pre-defined data-types.

To install the UDT for Teradata:

Log in to the server as the user with the required permissions.
Navigate to the /opt/protegrity/ directory.
To install the UDT setup for Teradata, run the following command:
```
./PepTeradata_UDTSetup_Linux_x64_10.0.0+x.sh
```

Press ENTER.
The prompt to continue the installation appears.

Creating the Teradata User Defined Types (UDTs)

The Teradata Data Warehouse Protector automatically creates the To-SQL and From-SQL transform, the ordering, and the necessary casts for a distinct UDT once the CREATE TYPE statement is issued.

On the Data Warehouse Protector installation, the /databaseprotector/teradata/udt/ directory is created with the following files:

generate_udt_scripts.sh is an executable file that generates UDT scripts
pepteradataudt.plm is a library that contains protect and unprotect functions for UDT usage.

The generate_udt_scripts.sh generates UDT scripts using the following command:
