NPrinting High-Availability Deployment and failover?

[kalvinchan]

How to achieve high availability deployment of Qlik NPrinting (NP)?  Would like to achieve:

- Assume 2 NP servers, serve as one primary + one secondary

- Both NP servers connect to the same 2-nodes Qlik Sense cluster site

- Primary NP server can failover to secondary NP server automatically

Any best practice and architectural reference?

Hi,

At the moment (September 2018) you can have only more Qlik NPrinting Engines.

If you want to have more that one server the only solution is manually backup the first and restore on the second (they must be at the same version). Then you can connect to one or to the other but there is nothing automatic.

For example, you cannot have two Qlik NPrinting Repositories synced automatically on different computers.

What about having the repository on a shared location??? that way you only have to start the second server and have a virtual IP for it, right? Do you know someone who has managed to do it?

Thanks

Hi,

I think you mean the whole Qlik NPrinting Server and not only the Qlik NPrinting Repository. You can install two servers and then switch on and off one of them but all must be managed manually. Each server must be connected with its Engines (you can connect many Engines to a server but an Engine can be connected only to one server at a time).

What I mean in my previous post is the you also need to manually keep the two servers aligned. For example if you create a new connection in a server you need to create it also in the second. You can export reports one by one from the first and import on the second. Both must be at the same version. Or you can backup one and restore on the second server. In any case there is nothing automatic to keep the content of more that one server aligned.

Best Regards,

Ruggero
