Dedicate a node for opening a qliksense app and onother node for reload task

[natalia21]

Hello everyone,

I would like to set a specific node for opening an app, and set another node for task reload for the same app. Is it possible to do this?

example :

qliksense app - App A

QMC reload  task App A - node X

Opening App A from Hub - node Y

Thanks,

Natalia

It is possible, see the example and links in https://support.qlik.com/articles/000050519 (How to dedicate a Qlik Sense RIM node to a particular application (APP)) and in https://support.qlik.com/articles/000030433 (Load Balancing Rules: Have only specified streams/apps to be available on a dedicated node).

Hi Miguel,

Thank you for your response.

I have tested the  solution https://support.qlik.com/articles/000050519 (How to dedicate a Qlik Sense RIM node to a particular application (APP)) , but I need a solution that involving only one access  URL, here we have 2 virtual proxy URL. The  users  should access only one URL for all app.

If you want to use one single URL for all users, you will need to set up a proxy or load balancer in front of the Qlik Sense deployment. This could be a physical device (e.g.: an F5 network load balancer) or a server running IIS, Apache or the like configured as a proxy.

Hello @Miguel_Angel_Baeyens ,

I have the same issue  @natalia21  i have 2 nodes and one central, i follow this link https://support.qlik.com/articles/000030433.

Can we have something like, in virtual proxy, load balancer :

 add the node  dedicated to specific apps on the virtual proxy of the  node with access  URL ?

Thank you.

I'm not sure I follow. You can have 2 nodes and 1 central, that's perfectly fine.

You can pin apps to be open on one of those 2 nodes, so they are only available on that node, also without any problem.

However, how the user gets to the right virtual proxy, unless they specify it on the URL?

If there is a load balancer in front of the virtual proxies, such load balancer will have to be configured as to redirect requests from the set of users to the corresponding virtual proxy. This setup is external to Qlik Sense and has to happen externally to Qlik Sense.

Separately, when you create a virtual proxy, you can link to which of the proxies does that virtual proxy link to: https://help.qlik.com/en-US/sense-admin/June2020/Subsystems/DeployAdministerQSE/Content/Sense_Deploy... and also https://help.qlik.com/en-US/sense-admin/June2020/Subsystems/DeployAdministerQSE/Content/Sense_Deploy...

Hello @Miguel_Angel_Baeyens ,

Thank you very much for your answer.

We have 4 applications, 3 large apps and one normal.

We would like the 3 large  apps be opened in node 2

and the normal app always be opened in node 1.

the URL we have communicated to users is that of Node 1.

Here's what I've been doing:

- in virtual proxy of Node 1 I added Node 2.

- In the Load balancing rules section, i disabled the default rule ResourcesOnNonCentralNodes and add new rules for node 2 (to dedidcate to large apps)(i follow this https://help.qlik.com/en-US/sense-admin/June2020/Subsystems/DeployAdministerQSE/Content/Sense_Deploy...)

So i dont understand the part about the setup external to qlik sense, can you please give me more details ?

Thanks a lot.

ZL.

Often, when there are several nodes and specifically, when several nodes are behind a load balancer (physical devices or software ones) the URL communicated to the users does not belong to any of the nodes in the Qlik Sense cluster, but instead, to that of the load balancer.

If you are not using a load balancer in front of the virtual proxies and your users communicate directly to the virtual proxies, you can ignore that, there is nothing else to do.
