Teradata

Teradata is one of the original enterprise database technologies that exist both on-premise and in the cloud. Teradata's robust platform is a best-in-class enterprise data platform, and its database technology is capable of handling massive transactional and analytical workloads.

Teradata Prerequisites:

• Versions (10 or above) are supported
• Determine which way to connect: Default or SSH Tunneling
• Firewalls on your database server should allow incoming connections through the public internet on your Teradata port (typically 1025 unless customized).  
• Be sure to Our IP Grantlist / Whitelist our IP Addresses for cross network database server network access
• Consult with you Teradata administrator as needed on the setup
  • We suggest creating a new read-only user and new role to delineate this user service account for DLH.io from any other user access to your database, however, using an existing user and/or role is acceptable:
  • Create a Read-Only DLH.io user in your Teradata instance
    • We suggest creating a new user specific to DLH.io for read only access to your Teradata database(s), but you may already have an existing user in which case you can ignore this step:
      • Create a new user for DataLakeHouse.io using the following or similar example Teradata logic replacing <new_username> with a user name that you choose (we recommend 'datalakehouse_ro' to signify a read-only user), and choose a good password that complies with your security policies: CREATE USER <new_username> AS PASSWORD = "tmp!password", PERM=1000000;
      • Grant the User Access to the Source Database
        • Using a direct user GRANT or by creating a role, or other means, provide the new user created above with permissions to read from the source database, for example: GRANT ALL ON <existing_source_database> TO <new_username>;

Instructions (Basic Connector Setup)

Remember DLH.io connects to your database instance with credentials supplied by you. We store your credentials securely with our bank-grade protocols.

1. On DLH.io, Enter your Credentials and Other Information in the Fields
   • Click on the Add New Source for Teradata, and in the resulting new source page update the form with your connection information...
   • Enter in the Name/Alias field, the name you'll use within datalakehouse.io to differentiate this connection from others
   • Enter in the Target Schema Prefix field, is the prefix of schema(s) that gets created on your destination target connection database for each of the schemas you load in this connection.
     • Alphanumeric characters only. It must start and end with a letter but can contain an underscore(_).
   • Enter in the Server/Host field, the name of the public server name or the IP Address (most customers use the IP for this field)
   • Enter in the Port field, where this database is accessible and the firewall restrictions are open
   • Enter in the Database field, the name of the database to connect
   • Enter in the Userame/Alias field, the username of user you created in the steps above to give access to DataLakeHouse.io
   • Leave Auth Type field alone. It is set to password because DataLakeHouse is using TLS and requires username and password credentials to access the database
   • Enter in the Password field, the password for the user you created in the steps above
2. Click Save & Test
   • This attempt to connect to your database with the credentials provided.
   • A message of success or failure will be shown
     • If success you'll be prompted with the schema objects objects of the database and will need to complete the final steps for configuration shown below.
     • If failure happens with the test connection, the connection is still saved but you will need to correct the failure based on the failure reason information provided in the message
