DSC, ClientHandler, BARCmdline, and BARPortlets must be on the same version.
Important:

Make sure the DSC is up and running before installing ClientHandler.

Beginning with DSA release 16.10, the BARNC process queries the broker (ActiveMQ) for the existing DSC instances pointing to the broker. If the DSC is not running, autodiscovery fails.

DSA Package Installation Directory Notes
ClientHandler base_dir/teradata/client/version/dsa You can specify the directory as base_dir.
Do not use / or /usr as the installation directory. The permissions for the specified directory are modified so that the service user can access the directory.
  1. Verify that the DSC is up and running.
  2. On the BAR server, unzip and extract the script rpm file:
    tar zxvf clienthandler_linux_arch.xx.xx.xx.xx-######.tar.gz
    linux is the OS, arch is the architecture, xx.xx.xx.xx is the version number, and ###### is a unique number.
    A directory with the format clienthandler.xx.xx.xx.xx is extracted in the current working directory.
  3. Run the installation script from the extracted directory, where arch is the architecture, xx.xx.xx.xx is the version number, and ###### is a unique number. ./clienthandler_install.sh -r clienthandler-xx.xx.xx.xx-######.
  4. Enter values for ClientHandler. If you are doing an upgrade, the previous settings are displayed and can be changed, if desired. The following table displays prompts in the order in which they are received.
