Changing the role of a node in a cluster

You can assign the Control node role to any cluster node. The other nodes will have the Secondary node role. For example, you may need to change the roles due to a failure of the Control node, or if you have to remove the application from this server.

To assign the Secondary node role to the Control node:

1. In the application web interface window, select the Nodes section.
2. In the cluster nodes table, select the node with role Control.

   The node settings window opens.

3. Click Change role to Secondary node.

The node with role Control will become a node with role Secondary. The web interface of the Secondary node opens.

To assign the Control node role to a Secondary node:

1. In the application web interface window, select the Nodes section.
2. In the cluster nodes table, select a node with role Secondary.

   The node settings window opens.

3. Click Go to manage node.

   Authorization page opens in a new browser window.

4. Enter the user name and password of the application administrator.

   The web interface of the node with role Secondary opens.

5. Click Change role to Control node.
6. In the confirmation window, click Yes.

The node with role Secondary will become the node with role Control.
