Multi-node

Errors started in qlik after adding the second node. What settings should I pay attention to?

By any chance are you using ODBC DSN connections? If so, have you installed the drives and configured the new node?
If using folder connections, are you using UNC Paths?

I'm assuming the problem is with connections but best option is to check the script log:

HI Hi _MIkhail

Sorry I missed the message in the screenshot, the execution failed in the engine, it means that the reload didn't start if there is no script log, have you already reviewed the engine logs? you will probably find an error showing the cause of the issue.

Hope it helps.

Engine cannot find the application on the second node, but on first everything is OK

Hi _Mikhail

Do you have any load balancing rules? Is the proxy load balancing to both nodes?

Do you have any recommendations?

Hi @_Mikhail_

It seems those are the load balancing rules, basically the error stands that the app can't be found, have you checked in the Audit section in the QMC if the app can be load balanced to both engines?

Kind Regards,

All apps can be load balanced to both nodes

Hi @_Mikhail_

At this point it will be better to submit a new case so we can gather more information and analyze the issue.

Let me know if you need some guidance on how to create the case or I can help if you have any questions.

Kind Regards.
