Stop a Cluster

This article explains how to stop clusters in a native cloud deployment on AWS.

Prerequisites

The database access node must be running.

Procedure

This procedure uses the c4 and confd_client command-line tools in a Linux terminal. For more information about these tools, see Exasol Deployment Tool (c4) and ConfD.

Step 1: Connect to COS

Connect to the cluster operating system (COS) using c4 connect -i PLAY_ID -s cos.

Example:
Copy 
./c4 connect -i c3275f84 -s cos

For more information about how to use c4 connect, see How to use c4.

Step 2: Stop the cluster

To stop all the nodes in a cluster, use the ConfD job infra_db_stop.

Parameter name Data type Description
db_name string The name of the cluster to be stopped.
Example:
Copy 
confd_client infra_db_stop db_name: WORKER1

Stopping the main cluster will stop the database on all worker clusters.

Step 3: Disconnect from COS

To disconnect from COS, use Ctrl-D.

Verification

To verify that the cluster has stopped, use c4 ps.
