Install Teradata QueryGrid Manager software on one or more dedicated physical or virtual machines other than the data source nodes of your Teradata QueryGrid environment. For system requirements, see Prerequisites.
When you install Teradata QueryGrid Manager software on more than one machine, you can cluster the Teradata QueryGrid Manager instances. A database can only be managed by a single QueryGrid Manager cluster, all systems in your environment must be managed by that same cluster to communicate through QueryGrid. Therefore, Teradata recommends creating one QueryGrid Manager cluster to enable all systems across the enterprise to exchange information using QueryGrid.
Install the latest version of Java 8 on each dedicated physical or virtual machines.
If the correct version of Java is not automatically detected, you can set the path to the Java home directory in /etc/opt/teradata/tdqgm/setenv.sh.For example:

If this is the first Teradata QueryGrid Manager instance installed, confirm that the default value for the publicAddress is appropriate for your environment.
- Open the /etc/opt/teradata/tdqgm/server.properties file.
If the default value is not appropriate, see Modifying the publicAddress, bindAddress, and clusterAddress for a QueryGrid Manager Instance.
You can also edit the bindAddress and clusterAddress.
- If the publicAddress is a hostname (not an IP Address) and cannot be resolved from the data source nodes using DNS, add the QueryGrid Manager server or servers to the /etc/hosts file of each node in the data source system.
