If an upgrade of Teradata Alerts does not complete successfully, the following steps allow you to back the system down to the previously installed version. Note that xx represents the specific version of the software.

This procedure is only for backing down from Teradata Alerts 16.20.00.xx to release 16.10.00.xx, 16.00.00.xx, 15.11.00.xx, 15.10.00.xx, 15.00.00.xx, or 14.10.00.xx.

If backing down to an earlier version of Teradata Alerts, make sure that any applications that require the version being removed are also backed down.
  1. If the Teradata Notification Service is running on a Windows Server, stop the service.
  2. If the Teradata Notification Service is running on a Linux Server, stop the tdnotification service:
    /etc/init.d/tdnotification stop
  3. Stop all of the Teradata Alerts services on all Teradata Viewpoint servers. Also stop the Teradata Viewpoint services:
    • /etc/init.d/dcs stop

    • /etc/init.d/camalert stop

  4. Restore the last successful backup of the previous version of the Teradata Alerts database.
    The duration of this process varies and is based on the size of the database. If you have a clustered environment, perform the restore against the primary database server.
