Qlik Sense Multi-nodes site guidance

OmarBenSalem — Mon, 15 May 2017 13:43:32 GMT

Hi all,

I want to have a multi-node site. The demand is as follow:

1) One server for administration, QMC, handling autorisations, doing reloads, etc.

2) A second server to just CONSUME and Develop new Apps; the users will only have access to the HUB within this server.

What should I do? How should I proceed?

Will the first server be a master one? What should it have as services?

What services should exist in the second one? to only consume and develop apps? (the apps should be reloaded in the first server)

I hope my question is clear enough.

I suggest you to have a light master node (on the master node by default runs all services) and size the RIM node based on your actual needs. If you need RIM node just consume apps, you want to install the Engine layer on it (optionally you can also add the proxy if you want to differentiate the ipaddress between admins and users access).

As configuration you need to create a sync rule to allow apps runs only on RIM node.

Then you need to consider where run the reload tasks. If overnight you can use the same RIM node, otherwise consider to use the Master node

Thanks Vicenzo !

Can you tell me how to create a sync rule to allow apps run only on RIM node?

and how to use only the Master node for reload tasks?

And if I fully understand, the Rim node should only have an Engine service + (proxy which is optional?)

Thank you very much,

I'm really in need of guidance and couldn't find anyone in the community to help..

Hi Vicenzo, can you take a look at this?

Multi-Node site, can't access to the HUB in the RIM node

For the sync rule have a look here Configuring sync rules ‒ Qlik Sense. An alternative to the sync rule (maybe better) is to put the Proxy service on both (Master node and RIM node) each proxy need to point to the local engine only (do not balance on both engines) this assure you all people which access through the RIM proxy will use RIM engine, so apps will be loaded only on that Engine.

Hi Vicenzo,

My central node runs all services

My RIM node runs only repository, engine and proxy services

I allowed http connexion in both proxies

the hostname of the Rim node is 192.168.1.189

Now, if I do as you said:

load balance Central node with Central

Load balance Rim node with Rim node

and now, try to access to the HUB in my rim node:

here is what Il have:

Now if for the Central node, I do the load balancing with Central Node

And for the RIM node I also do the load balancing with the Central Node:

I can access to the HUB and see the streams and apps, but when I try to open an app, this happens:

Any idea on what I am doing wrng?

Another thing; my nodes are Virtual Machines,

Re: Qlik Sense Multi-nodes site guidance

Vincenzo_Esposito — Wed, 17 May 2017 09:18:33 GMT

There is apparently a problem with the RIM Engine service, the configuration you made seems correct. Virtual Machines are supported, so I do not expect problems come from there. Be sure port 4748 (Engine comunication) on RIM node is open

jog‌ can you please assist on this?

I'm sorry Omar, I really can't. I suggest contacting the closest Qlik office, resellers or Qlik Partner eventually try to open a ticket to Qlik support

Hi,

You must add the ip you acces on the virtual proxy \ advanced \ Host white list

I already did it.. I'm really confused..

Hi Omar,

Don't really understand your load balancing logic. You want to make sure your users are only on the RIM node, correct?

Secondly, can you check if you can create a new app and if you can access it? Maybe something to do with how you have set up your synchronization rules.

Re: Qlik Sense Multi-nodes site guidance

OmarBenSalem — Tue, 23 May 2017 09:45:08 GMT

Thank you Martin, I've become desperate for help...

Well, It's the first time I'm dealing with such a demand; so I'm really confused on how should I proceed.

The demand was to have the master node with all the charge (reloads, administration etc)

and the RIM node will serve as the HUB where users will only access and create apps (those apps will be reloaded by the master node)

What I did:

Master Node : all services

Rim node : engine + proxy (and its virtual proxy load balanced with the central node; I thought that doing this will allow to access to the apps loaded and reloaded within the central node; no?)

Now, to answer your question, I can create an app within the rim node; I can even see the streams and apps created within the Central node;

but when I try to access to the app, I have this error:

And more importantly, I did not add any synchronisation rule (don't even know how to do it);

The only configurations I made is as I mentionned above; I want all the apps to be accessible in the RIM node (depends on the user authorisation); and I want the users to be able to create apps within the rim node (those apps will then be reloaded within the central node)

Any idea on what I'm doing wrong? Any guidance? Please?

Interesting -

Load Balancing only redirects the User Session to a different node - I suggest deactivating it for now. Not sure it will be possible for users to create & reload apps from the RIM node without a scheduler installed.

Did you install your environment using shared or rep sync?

Thanks,

Martin

Re: Qlik Sense Multi-nodes site guidance

OmarBenSalem — Tue, 23 May 2017 10:25:02 GMT

I installed it using synchronised persistence.

I do not want apps to be reloaded within the RIM node; I want the RIM node to serve as a HUB where users can see the apps and create them; now, within the CENTRAL node; we will have a schedule, and thus all the reload of the apps will be done in the CENTRAL node.

Now, if I do as you said, and remove the central node from the load balancing of the RIM node:

(see the the msg in yellow; (must add server nodes to load balancing for users to be able to ACCESS APPS)

When I try to access to the RIM node's hub, I cannot anymore:

(the proxy can't load balance the engine services)

What a Headache

Hi Omar - I am not sure as I don't work with multi-node environments - jog - is this something you can look at?
