If an upgrade of Teradata Viewpoint does not complete successfully, the following steps allow you to back down to the previously installed version of Teradata Viewpoint.
The only supported mechanism to backdown Teradata Viewpoint is to use VM&F during the upgrade.
- Reboot back into the alternate boot environment that contains the copy of the root partition prior to the upgrade.
- Stop all of the Teradata Viewpoint services on all Teradata Viewpoint servers by typing:/opt/teradata/viewpoint/bin/vp-control.sh stop
- If the Teradata Notification Service is running on a Windows server, stop this service.
- If the /data/db-backup directory exists and the creation time matches the time of last upgrade, do the following:
- Move the existing /data/viewpointdb directory to another location.
- Replace it with the /data/db-backup directory.
- If the /data/db-backup directory does not exist or is not recent, restore the last successful backup of the Teradata Viewpoint databases.The duration of this process varies depending on the size of the databases. If the Teradata Viewpoint databases are in a clustered environment, perform the restore against the primary database server.
- Restore the Viewpoint portal.
- Uninstall the Viewpoint package:rpm -e --nodeps viewpoint
- Reinstall the version of the Viewpoint package that was uninstalled:rpm -ivh viewpoint*.rpm
- Run the post-upgrade setup script:/opt/teradata/viewpoint/portal/bin/setup.sh
