Checking cluster health

The check cluster health feature checks whether the Db2® Big SQL database and all Db2 Big SQL nodes are running. It verifies database connections, adds missing database partitions, and registers the new database partitions.

Ensure that any dead nodes are removed before checking cluster health. Dead nodes are Db2 Big SQL nodes that are not accessible or that are unable to communicate over the network.

To check whether your cluster has any dead nodes, specify the -checkDeadNodes option in the Db2 Big SQL administration utility.
To remove dead nodes, specify the -removeDeadNode. This action enables you to perform a full cleanup on the dead nodes in your cluster.

To enable the cluster health feature, specify the -health option in the Db2 Big SQL administration utility. For more information, see Db2 Big SQL cluster administration utility.

You can find the cluster health check log files at /tmp/bigsql-health-check-*.log.
