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:
  • BAR integrated master and media servers (also referred to as DSC server)
  • BAR media servers (also referred to as 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.
Perform these steps on each server in the DSA environment.
  1. Log on as root to the server.
  2. Open the file /etc/ntp.conf file.
  3. Add the following to the end of the file and save the changes: server hostname 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 re-start the NTP service manually, type: /etc/init.d/ntp restart
