Before you begin:

About this task:

To replace a failed node, you must install the Hybrid Data Pipeline server on a new host machine and configure your network load balancer to use the new node. In addition, references and routing information related to the failed node should be removed from the load balancer configuration.

Note that during the initial installation of the Hybrid Data Pipeline server, the installer writes properties files, encryption keys, and system information to the key location. When performing subsequent installations on additional nodes, the key location must be specified to ensure consistent configuration of the service across nodes. For installations on additional nodes, the installer bypasses prompts for load balancing, SSL, system database, and On-Premises Connector configurations, as this information is provided by the files written to the key location.

  1. From a command-line prompt, navigate to the directory where you saved the product file. Alternatively, place the product file directory on your path before proceeding to the next step.

    The product file has the format PROGRESS_DATADIRECT_HDP_SERVER_nn_LINUX_64_INSTALL.bin, where nn is the version of the product.

  2. Make the file an executable using the chmod command. Then, press ENTER. For example:

    chmod +x ./PROGRESS_DATADIRECT_HDP_SERVER_nn_LINUX_64_INSTALL.bin

  3. Run the executable.
    • Console mode

      ./PROGRESS_DATADIRECT_HDP_SERVER_nn_LINUX_64_INSTALL.bin -i console

    • GUI mode

      ./PROGRESS_DATADIRECT_HDP_SERVER_nn_LINUX_64_INSTALL.bin

      Note: If the installer cannot continue with a GUI installation, a message is displayed and the installation continues in console mode
  4. Specify an installation directory.
  5. Provide the hostname of the machine on which you are installing the Hybrid Data Pipeline server.
  6. Select the Custom installation type.
  7. Provide the key location and other information as prompted.
  8. Review the installation summary, and proceed with the installation.
  9. Configure the network load balancer.
    1. Configure the network load balancer to use the new node.
    2. For deployments that include the On-Premises Connector, configure the load balancer to handle requests to backend data stores. (Refer to Load balancer configuration in the Deployment Guide for details.)
    3. Remove references and routing information related to the failed node from the load balancer configuration.

What to do next:

Monitor your environment to ensure that requests are being distributed by the load balancer and results are being properly returned to client applications.
