Configuring additional Unity servers or Teradata systems in the Unity environment requires usernames and passwords. Unity has a tool to provide these credentials in a convenient and secure way. This is the recommended way to collect the usernames and passwords required to install and configure Unity.

  1. On the primary Unity server, use the unityPasswd tool.
    # /opt/teradata/unity/bin/unityPasswd
       Welcome to the Teradata Unity password tool.
        This interactive tool will allow you to set passwords required for maintenance on
        your Unity & Teradata environment in a safe an secure way. The password values set
        will be stored in an encrypted format in TDWallet on this server.
        This tool simply collects passwords. It does not perform any changes on the unity
        servers or Teradata systems. It will validate the passwords you have entered are
        correct by attempting to connect to the unity server or Teradata system.
        This tool will NOT affect or change any passwords or value required to run Unity.
        These values are only used for maintenance.
        At the conclusion of the maintenance, you can remove these passwords using:
        # unityPasswd --erase
        Removing any current passwords.

        Would you like to provide the credentials to configure a:
        1. Unity server?
        2. Teradata system
        Please enter 1 or 2:
    The unityPasswd tool attempts to verify the passwords by connecting to the specified systems or Unity servers.
  2. Verify the passwords before starting a configuration change:
    # /opt/teradata/unity/bin/unityPasswd --check
  3. When the configuration change is complete, remove stored passwords using the --erase option to secure the environment:
    # /opt/teradata/unity/bin/unityPasswd --erase
