Services Mapping

Kyvos Manager lets you configure services for the BI Server, Web Portal, Postgres Server, and Standby Postgres Server on the cluster nodes.

You can configure services for nodes at the time of adding new nodes or migrate roles later at any time.

Note

  • From Kyvos 2024.3 onwards, you can only configure one service either BI Server or Query Engine on a node. No other service can be configured on a BI Server or Query Engine node. Ensure that this applies to all Cloud Deployments.

  • You can see the last performed node and service mapping operation details, including progress status and start time, by clicking the i icon located next to the Revert button.  To view more comprehensive details, simply click the View Details link, which will take you to the Operations page, where you can view the operation information in detail. 

  • On Azure Marketplace, the license information for the Query Engine and BI Server will not be available for Kyvos Managed Application and Kyvos Single Node Standard installation. 

Migrate Services

To migrate services from one node to another, perform the following steps.

  1. On the navigation pane, click Kyvos and Ecosystem > Node and Services. 

  2. On the Node and Services page, you will see a list of all the nodes configured in the cluster.

  3. On the right, you will see the number of instances configured in the system for each service and the number allowed in your license. 

  4. Use the Services drop-down lists to select the role that you want to assign to the node.

Note

  • The service assignment must comply with the number of instances allowed by your licenses. For example, if your license allows two BI Servers, you cannot assign the BI Server service to more than two nodes. Ensure that this is not applicable to Kyvos Marketplace.

  • When enabling Kyvos Manager HA, if the node being removed has a Kyvos Manager instance, it must be removed before removing the Kyvos Web Portal node.

  1. Once done, click the Save button.

  2. Enter your Kyvos Manager Password to continue and then click Save. 
    NOTE: From Kyvos 2023.3 onwards, if you want to start Kyvos services, select the Start Kyvos Services checkbox. 

    The Operations page displays the details of role migration. Once the operation completes, you will see the new services on the Dashboard and Node and Service Mapping page.

Managing Nodes

Kyvos allows you to add as many nodes to your cluster as you want. However, the roles that you can assign to the nodes are governed by your Kyvos License.

In this section, you will learn the following:

Adding a Kyvos Core Service Node

Note

  • Applicable in all environments except Kyvos Single Node Standard (SNS), Kyvos Single Node Installation (SNI), and environments that do not support node scaling.
