How to Configure a Rim Node to Function Only as a Scheduler Node in Qlik Sense

jpjust — Sat, 20 Aug 2022 09:01:10 GMT

All,

I have the following services on one of the RIM node.

I want this node only to be scheduler node, in order to do that which services should be disabled?

Thanks

Hi @jpjust,

For a Scheduler Rim node, you'll need the Repository, Engine and Scheduler services. See Qlik Sense Help entry Deployment examples of nodes running Qlik Sense services, which states

Scheduler: A node that manages scheduled reloads of Qlik Sense apps and other types of reload triggering. It includes the QRS, QSS, and QES services. In order to perform reloads the QSS requires the QES to be running on the same node.

Best Regards

Thanks for the answer. So I don't need to enable Proxy service, correct? And If I don't enable proxy service, this node can't be an failover node since I understand that in-order to delegate an node as fail over node, all the services needs to be run.

Thanks

@jpjust,

Correct. For a node to be a failover candidate, it must run the following services:

Qlik Sense Repository Service
Qlik Sense Engine Service
Qlik Sense Proxy Service
Qlik Sense Scheduler Service

Best Regards

Hello @jpjust ,

Correct, proxy service is not needed.

For a node to be a failover candidate, it must run the following services:

Qlik Sense Repository Service
Qlik Sense Engine Service
Qlik Sense Proxy Service
Qlik Sense Scheduler Service

Configuring failover for central node resiliency ‒ Qlik Sense for administrators

Cheers,

Albert

I don't think we need proxy service

Hi All,

If I disable proxy service on my newly added scheduler RIM node, my Proxy status is disabled under Proxies for that Node. Is this OK? Please see the screenshots below.

Hello @jpjust,

That should be ok as the proxy service is indeed disabled and not installed.

Cheers,

Albert

Hi,

So to make a rim node as a reload node. You just enable the scheduler services ? How do I test a reload task on this specific node?

Hello @AdrianOh ,

You mean only for testing? if yes, just stop the services on the other node.

Cheers,

Albert

I never thought of this. Do you mean stop / disable the scheduler services on the QMC on the other node? Will give it a try .

Is there way also to force some task to run on the new node? Like a load balance rules or some sort ?

Thanks

Hello @AdrianOh ,

Exactly, to disable/stop the scheduler service. Just got that idea if needs to be tested, I would expect that to work, but I haven't be able to test it myself yet so kindly let me know the outcome.

As of today, I am afraid tasks cannot be force to be executed on a particular node. I kindly suggest to vote on Ideation if there is an existing idea on this, otherwise kindly create a new one and share it here, so we can vote on it too.

Cheers,

Albert

So how does the load balance work for schedule task? Automatically pick up? Round robin?

Kindly review:

Qlik Sense Scheduler does not load-balance properl... - Qlik Community - 1716963

I also recommend:

Hi Dear @Chip_Matejowsky

Thanks for the answer, i have a similar situation, we have one central node and three RIM Nodes, the target of two of three RIM Nodes is only run task, the Enginee, Repository and Scheduler Windows services are runnning on RIM Task nodes, if i deactivate Enginee flag on nodes section on QMC, the central node not send task to RIM Nodes.

I don't want active enginee on this nodes because i neeed the resources for task, not for users

Can you help me please
