Switching environments dynamically in on demand reporting

[deep2021]

Hi,

We have separate environments for production and disaster recovery.

We are also using on demand reporting. Can you please suggest if the production server down how to switch over the DR server dynamically. 

Is there anything do we need to configure is the button actions.

Can you please suggest on this.

Thanks

Hi,

The Qlik NPrinting On-Demand button on Qlik Sense apps contains the link to the Qlik NPrinting Server and it is a fixed string. Based on that link the list of the Qlik NPrinting apps, the list of related connections and reports. So, if you want to move from production server to the disaster server you have to manually edit the links. Or you can create a copy in the disaster server and edit the links in order to be ready in case of disaster. 

Refer to https://help.qlik.com/en-US/nprinting/May2021/Content/NPrinting/On-Demand/Create-Report-On-Demand-QS...

Hi Ruggero,

This is actually interesting question and I am sure it is not as straight forward as it seems. 

We need to make sure that NPrinting Connections to Qlik Sense is also pointing to DR environment, right? In such Proxy name would have to be the same and certificates would have to be exchanged so NPrinitng would be able to succesfully run from DR env.

if that step can be achieved the only bit would be to configure Qlik Sense OnDemand extension button and maybe use a container to conditionaly choose the correct one based on hostname? That way maybe you could preconfigure it...

I understand there are multiple options and things to consider here so I am not jumping gun here with any additional solutions as I have never done it nor i tested it.

cheers

Hi Lech\Ruggero,

Thanks for your valuable response. 

Is there any possibilities, if the production server fails, it will be automatically redirected to the DR server.

There should not be any manual work.

Hi @Lech_Miszkiewicz ,

Yes, based on the Qlik NPrinting server link the connections are retrieved. So, if you have also two Qlik Sense servers, that need to be managed by changing the Qlik NPrinting connections. Connecting to different Qlik Sense server requires the certificates so you have to import them. 

So it is not an automatic process and my suggestion is to configure and test both environments before the disaster happens. For example also the users must be available in both environments.
