Elevating an existing Qlik Sense rim node to a Failover Candidate

[Benoit_C]

For information about Qlik Sense failover candidates, see Qlik Sense Failover Central node: Requirements and Considerations.

Out of the box, you need to toggle the option to enable a rim node as a failover node during first time setup. In this article, we will outline how to accomplish elevating an existing node to being a failover candidate primarily using the QRS APIs.

Steps:

1. Perform a GET /qrs/ServerNodeConfiguration/full API call
   
   
2. Copy the JSON response
   
   
3. Edit the JSON to include only the node that you want to elevate
           Remember to remove the []'s which bracket the JSON response
   
   
4. Change the failoverCandidate to be true and slightly modify the modifiedDate
   
   
5. Perform a PUT /qrs/ServerNodeConfiguration/{GUID_of_note_to_elevate} with the edited JSON in the body
   
   
6. Export full trusted root from existing Central candidate
   
   
7. Stop services on the newly elevated rim
   
   
8. Deleted the existing trusted root certificate on the newly elevated rim
   
   
9. Import the copy of the certificate that was previously exported from an existing Central candidate
   
   
10. Start all services on the rim

@Benoit_C 

we are trying to implement same steps to convert one of our existing RIM nodes to be a failover candidate through postman but getting below error.

403 No client certificate supplied.

The request was a legal request, but the server is refusing to respond to it. Unlike a 401 Unauthorized response, authenticating will make no difference.

We have tried importing QlikClient certificate to our local system where postman is installed.

but error persists. Kindly advise.
