If applicable in your environment, you can cluster Teradata QueryGrid Manager instances.
- Log on to the Teradata QueryGrid Manager TMS, VM, or server to include in a cluster.
From a console window, run the join-cluster script as root or the tdqgm user:
Select a join method.
Join Method ----------- 1. SSH - Provide SSH credentials to access cluster seed files 2. Token - Provide token to access cluster seed files using QGM web service Select join method [1-2]:
- Enter the hostname of an existing QueryGrid Manager instance to join; if using the token join method, specify the hostname of the QueryGrid Manger instance where the create-join-cluster-token script was run.
Depending on the join method selected, enter one of the following:
Option Description SSH Specify the login credentials for a user granted read permission to /etc/opt/teradata/tdqgm on that instance. Token Enter the token generated by the create-join-cluster-token script on one of the other QueryGrid Manager instances.
Enter the Data Center for this instance.
By default, data source nodes communicate with QueryGrid Managers in the same datacenter.
- Enter y at the prompt to continue with the clustering process. All the data on the instance that the cluster command is run from is replaced with the data from the first Teradata QueryGrid Manager instance, or the existing cluster, being joined.
