How to move NPrinting generated reports cache off operating system disk onto other disk or to shared storage?

[aeveltstra]

Hello!

By default, Qlik NPrinting caches its generated reports on the server that generates them, usually in c:\programdata (provided that the operating system lives on c:\).

For instance, for one of my "apps", NPrinting caches the generated reports here:

C:\ProgramData\NPrinting\apps\{app-id}\reports\published

The space on that drive is limited. I need to move the caches. Either to a different disk that has plenty of room, or to shared storage that already is accessible.

How do I make that happen? What configuration file do I edit?

Thank you,

Andre E. Veltstra

Hi, 

I suggest you start reading documentation first. It clearly says NPrinting can only be isntalled on C drive - full stop.

Second thing is that cache is not a file - it is a postgresql database  and therefore cannot be moved.

In short - what you are trying to do is not possible!

Other comments:

• are you really on 17.3 version? 
• If you are - i suggest you upgrade as you are 4 years behind the latest release and a lot has changed since
• cache are not taking up that much space - so my assumption is that what causes your space on drive to disapear is use of news stand and reatining a number of history reports on it.

All above is well documented on https://help.qlik.com. Help has more than 500 pages to ready - so happy reading, there is a lot you have to digest.

cheers

Wow. I can only assume my communication skills are severely lacking, because that answer completely missed the ballpark. Thanks.

I see registry settings here:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Qlik\NPrinting Server

that tell NPrinting where to find its data files.

One of the entries is ProgramDataLocation. This seems to indicate that I can tell NPrinting to look for its data elsewhere.

Will it suffice to update these registry entries? And maybe restart the NPrinting services? Or are more steps involved?

I updated my question to reflect the actual version of NPrinting we're using. Thank you for pointing that out!

Hi,

From the Release Notes:

Qlik NPrinting must be installed only on C: drives
Qlik NPrinting Server, Engine, and Designer can only be installed on C: drives. Any attempt to install them on
a different drive will result in task failures.

At the moment (February 2021) this requirement is still valid so there is not a supported way to move reports cache on a different storage.

Best Regards,

Ruggero

Hi!

What am I missing here? The release notes talk about where NPrinting components get installed. They don't talk about where the reports cache must be stored. Do they? How does a statement about the one lead to a conclusion about the other?

Thank you,

Andre

Hi,

Everything is installed on the C drive and cannot be moved. Also the connections caches, the templates, the generated reports published on the NewsStand etc are stored on the C drive and there is not a configuration parameter to change their storage location in a way that is also officially supported. 

This feature is already in the ideation https://community.qlik.com/t5/Suggest-an-Idea/Possibility-to-move-the-NP-installation-NP-Database-ou... so you can vote for it.

Best Regards,

Ruggero
