The steps for upgrading Teradata QueryGrid Manager are similar to those for installing it, whereas the upgrade processes for connectors, fabrics, and node software differs from the installation process.
This protocol provides for pushing changes to all systems before implementation, allowing you to test new connectors and fabrics on production deployments without affecting production workloads.
The upgrade process for QueryGrid node software differs somewhat from the installation process, with the final deployment steps being handled automatically by the pre-existing version of the software.
- Previously collected log data and query metrics are reset.
QueryGrid metrics that display in Viewpoint are maintained and not reset.
- Query summarization and system health checks are suspended during the rolling upgrade until all Managers are upgraded to the new version. Teradata recommends you perform rolling upgrades in quick succession to minimize the amount of time different versions are running simultaneously, while still making sure each instance is upgraded successfully and comes online before starting the next upgrade.
- Wait to perform diagnostic checks and node install operations until after the rolling upgrade completes to avoid timeouts or failure.
