During DSA component installation, user accounts, initialization scripts, and environmental variables are created. You can verify proper installation by checking for these items.
  1. Verify that the ClientHandler web service is listening on all media servers by typing # netstat -an | grep 15402 | grep LISTEN.
  2. Verify that the DSA components exist in the following file paths:
    Package/Script File Path
    DSC Package /opt/teradata/client/version/dsa/dsc
    DSC Service Initialization Script /etc/init.d/dsc
    BAR Client Handler Package base_dir/teradata/client/version/dsa/clienthandler
    BAR Client Handler Service Initialization /etc/init.d/clienthandler
    BAR Command-Line Package base_dir/teradata/client/version/dsa/commandline
  3. Verify that the DSCUSER was created with the proper uid.
    # id -u dscuser
    The response should be positive and return the uid configured during install time.
  4. Restart the session and verify that the following environmental variables were created:
    Environment Variable Setting
    DSA_CONFIG_DIR /etc/opt/teradata/dsa
    DSA_LOG_DIR /var/opt/teradata/dsa/logs
    DSA_LOG_LANDING_ZONE_DIR /var/opt/teradata/dsa/landing_zone
    DSA_DSC_ROOT base_dir/teradata/client/version/dsa/dsc
    CLIENTHANDLER_ROOT base_dir/teradata/client/version/dsa/clienthandler
    BARCMDLINE_ROOT base_dir/teradata/client/version/dsa/commandline
    base_dir and version are resolved at install time. The PATH environmental variable is configured with the paths to dsc.sh and dsc for the BAR command line.
