The time must be synchronized between all servers in the DSA environment so that messages expired from the ActiveMQ server are not lost. The servers include:
  • DSC server
  • DSA media server
  • Viewpoint server
  • DBS node(s)

The servers should be set in the same time zone with teradata-ntp to achieve synchronization of timestamps.

Use this procedure for each server in the DSA environment.

  1. Log on as root to the server.
  2. Open and edit /etc/ntp.conf.
  3. Add the following to the end of the file where host is the hostname of the time server: server host For example:
    server time00.teradata.com
  4. To verify that the NTP service runs when the server starts up, type: chkconfig ntp on
  5. To restart the NTP service manually, type: /etc/init.d/ntp restart
