Configuring Teradata QueryGrid Manager

  1. From the Azure portal, note the private IP Address, public IP Address or the public DNS of the QueryGrid Manager VM.
  2. From the SSH client console, log on to the QueryGrid VM using the same authentication type you chose when you deployed the VM.
    Authentication type Action
    SSH private key Enter the following:
    # ssh -i ssh-private-key.pem azureuser@VM-private-IP-address
    where:
    • The ssh-private-key is the private key file (.pem) specified when you deployed the VM.
    • The azureuser is the user name specified when you deployed the VM.
    • The VM-private-IP-address is the private IP address of the QueryGrid VM.
    Password Enter the following:
    # ssh azureuser@VM-private-IP-address
    Password: password
    where:
    • The azureuser is the user name specified when you deployed the VM.
    • The VM-private-IP-address is the private IP address of the QueryGrid VM.
    • The password is the password specified when you deployed the VM.
  3. Switch to the root user environment.
    # sudo su -
  4. Add the user to the QueryGrid Manager user group to prevent permissions errors.
    # sudo usermod -A tdqgm azureuser
  5. Reset the default viewpoint and support passwords:
    # /opt/teradata/tdqgm/bin/reset-password.sh
  6. [Optional] Change the private IP address to public IP address.
    By default, a QueryGrid Manager VM uses a private IP address, used by QueryGrid-attached nodes and other QueryGrid Manager VMs to access it.
    1. Open the properties file:
      /etc/opt/teradata/tdqgm/server.properties.
    2. Modify the value of publicAddress with the public IP or DNS to be used.
    3. Restart the QueryGrid Manager VM.
  7. If you deployed multiple QueryGrid Manager VMs for high availability and used SSH for authentication you must provide the SSH private key when clustering them.
    Follow the instructions in Teradata QueryGrid Installation and User Guide, using the following option with the join-cluster.sh command:
    -k,--ssh-key-file filename
